BACKGROUND OF THE INVENTION
[0002] In fabric and home care industry, there is a strong need for new biodegradable cleaning
polymers to provide both excellent primary (i.e., soil removal) and secondary (i.e.,
whiteness maintenance) cleaning benefits for both hydrophobic and hydrophilic stains,
particularly under quick and cold wash conditions. In additional to the cleaning benefit,
fabric and home care composition comprising the new biodegradable polymers should
also provide delightful sensorial experiences for consumer, including suds profile
during wash, freshness profile during wash and after wash, fabric feel during wash
during wash and after wash.
[0003] The objective of the present invention is to provide a fabric and home care composition
comprising a fabric and home care ingredient, a graft polymer, and a modified polyalkyleneimine
/ polyamine (PAI / PA). The composition of the present inventions not only delivers
strong cleaning benefit, but also delivers delightful sensorial experience, particularly
good flash suds in the presence of soil. In addition, the combination of the graft
polymer with the modified polyalkyleneimine / polyamine (PAI / PA) improved sustainability
and biodegradability profile of the fabric and home care composition.

vinyl ester (weight percent being based on the total weight of vinyl ester monomers
B 1 being employed),
and wherein - more preferably - essentially no other monomer (B2) is employed.
Monomers (B2) may in principle any monomer polymerizable with vinyl ester-monomers
(B 1). For type I, II and III graft polymers, the backbone (A) contained within the
graft polymer according to the present invention may either be capped or not capped
(uncapped) at the respective end groups of the backbone. By consequence, within the
present invention, it is possible that the block copolymer backbone (A) is optionally
capped at one or both endgroups, preferably the block copolymer backbone (A) is not
capped at both endgroups or, if the block copolymer backbone (A) is capped, the capping
is done by C
1C
25-alkyl groups, preferably C
1 to C
4-alkyl groups.
[0054] In respect of the polymeric sidechains (B) contained within the graft polymer according
to the present invention, it is preferred that the polymeric sidechains (B) are obtained
by radical polymerization and/or the at least one vinyl ester monomer (B1).
[0055] As vinyl ester monomer (B1) any further vinyl ester besides vinyl acetate, vinyl
propionate or vinyl laurate may be employed which are known to a person skilled in
the art, such as vinyl valerate, vinyl pivalate, vinyl neodecanoate, vinyl decanoate
or vinyl benzoate.
[0056] Within the context of the present invention, it is preferred that no other monomers
besides those as defined above in connection with the at least one vinyl ester monomer
(B1) and the optionally present N-vinylpyrrolidone as optional further monomer (B2)
are employed within the respective polymerization process for obtaining the polymeric
sidechains (B). However, if any further polymeric monomers besides the monomers according
to (B1) and optionally (B2) are present, such monomers are present in an amount of
less than 1% of the total amount of monomers employed for obtaining the polymeric
sidechains (B). Preferably, the amount of said additional monomers is less than 0.5%
by weight, even more preferably less than 0.01% by weight, most preferably, there
is a total absence of any additional monomer besides the monomers (B1) and optionally
(B2).
[0057] In one embodiment it is also preferred that also monomers (B2) are present in an
amount of less than 1% of the total amount of monomers employed for obtaining the
polymeric sidechains (B). Even more preferably, the amount of monomers (B2) is less
than 0.5% by weight, even more preferably less than 0.01% by weight, most preferably,
there are essentially no monomers (B2) present besides the monomers (B1).
Within the present invention, it is particularly preferred that no monomers are employed
comprising an acid function. In particular, the monomers employed for obtaining the
polymeric sidechains (B) of the graft polymers according to the present invention
do not comprise any acidfunctional monomers such as acrylic acid, methacrylic acid,
maleic acid, itaconic acid, crotonic acid, vinyl-acetic acid or acryloxy-propionic
acid and the like.
[0058] The graft polymers according to the present invention preferably have a low polydispersity.
It is preferred that the graft polymer of the invention and/or as detailed before
has a polydispersity M
w/M
n of < 5, preferably <3.5, more preferably <3, and most preferably in the range from
1.0 to 2.5 (with M
w = weight average molecular weight and M
n = number average molecular weight; with polydispersity being without unit

). The respective values of M
w and/or M
n can be determined as described within the experimental section below.
Process of Making the Graft Polymer
[0059] Another subject-matter of the present invention is a process for preparing the inventive
graft polymers as described above in the various embodiments and variations thereof.
Within this process for obtaining at least one graft polymer according to the present
invention, at least one monomer (B1) and optionally a further monomer (B2) are polymerized
in the presence of at least one polymer backbone (A).
[0060] It has to be noted that the grafting process as such, wherein a polymeric backbone,
such as a polymer backbone (A), is grafted with polymeric sidechains, is known to
a person skilled in the art. Any process known to the skilled person in this respect
can be employed within the present invention.
[0061] Within the process of the present invention, it is preferred that the polymeric sidechains
(B) are obtained by radical polymerization.
[0062] The radical polymerization as such is also known to a skilled person. The person
skilled in the art also knows that the inventive process can be carried out in the
presence of a radical-forming initiator (C) and/or at least one solvent (D). The skilled
person knows the respective components as such.
[0063] The term "radical polymerization" as used within the context of the present invention
comprises besides the free radical polymerization also variants thereof, such as controlled
radical polymerization. Suitable control mechanisms are RAFT, NMP or ATRP, which are
each known to the skilled person, including suitable control agents.
[0064] In a preferred embodiment, the process to produce a graft polymer of the invention
and/or as detailed before comprises the polymerization of at least one vinyl ester
monomer (B1) and optionally at least one further monomer (B2) in the presence of at
least one polymer backbone (A), a free radical-forming initiator (C) and, if desired,
up to 50% by weight, based on the sum of components (A), (B1), optionally (B2), and
(C) of at least one organic solvent (D), at a mean polymerization temperature at which
the initiator (C) has a decomposition half-life of from 40 to 500 min, in such a way
that the fraction of unconverted graft monomers (B1) and optional monomer (B2) and
initiator (C) in the reaction mixture is constantly kept in a quantitative deficiency
relative to the copolymer backbone (A). In a preferred embodiment no monomer (B2)
is employed.
[0065] The amount of ((free) radical-forming) initiator (C) is preferably from 0.1 to 5%
by weight, in particular from 0.3 to 3.5% by weight, based in each case on the polymeric
sidechains (B).
[0066] For the process according to the invention, it is preferred that the steady-state
concentration of radicals present at the mean polymerization temperature is substantially
constant and the graft monomers (B 1) or (B2) are present in the reaction mixture
constantly only in low concentration (for example of not more than 5% by weight in
total). This allows the reaction to be controlled, and graft polymers can be prepared
in a controlled manner with the desired low polydispersity.
[0067] The term "mean polymerization temperature" is intended to mean here that, although
the process is substantially isothermal, there may, owing to the exothermicity of
the reaction, be temperature variations which are preferably kept within the range
of +/- 10°C, more preferably in the range of +/- 5°C.
[0068] According to the invention, the (radical-forming) initiator (C) at the mean polymerization
temperature should have a decomposition half-life of from 40 to 500 min, preferably
from 50 to 400 min and more preferably from 60 to 300 min.
[0069] According to the invention, the initiator (C) and the graft monomers (B 1) and/or
(B2) are advantageously added in such a way that a low and substantially constant
concentration of undecomposed initiator and graft monomers (B 1) and/or (B2) is present
in the reaction mixture. The proportion of undecomposed initiator in the overall reaction
mixture is preferably ≤ 15% by weight, in particular ≤ 10% by weight, based on the
total amount of initiator metered in during the monomer addition.
[0070] In a more preferred embodiment, the process comprises the polymerization of at least
one vinyl ester monomer (B 1) and optionally at least one other monomer (B2) in the
presence of at least one polymer backbone (A), a free radical-forming initiator (C)
and, if desired, up to 50% by weight, based on the sum of components (A), (B 1), optional
(B2), and (C), of at least one organic solvent (D), at a mean polymerization temperature
at which the initiator (C) has a decomposition half-life of from 40 to 500 min, in
such a way that the fraction of unconverted graft monomers (B 1) and optional (B2)
and initiator (C) in the reaction mixture is constantly kept in a quantitative deficiency
relative to the polymer backbone (A), wherein preferably at least 10 weight percent
of the total amount of vinyl ester monomer (B 1) is selected from vinyl acetate, vinyl
propionate and vinyl laurate, more preferably from vinyl acetate and vinyl laurate,
and most preferably vinyl acetate, and wherein the remaining amount of vinyl ester
may be any other known vinyl ester, wherein preferably at least 60, more preferably
at least 70, even more preferably at least 80, even more preferably at least 90 weight
percent, and most preferably essentially only (i.e. about 100wt.% or even 100 wt.%)
vinyl acetate is employed as vinyl ester (weight percent being based on the total
weight of vinyl ester monomers B 1 being employed), and wherein - if (B2) is present
- the weight ratio of optional monomer (B2) to monomer (B1) is less than 0.5, preferably
less than 0.4, more preferably less than 0.3, even more preferably less than 0.2,
and most preferably less than 0.1.
[0071] In an even more preferred embodiment of the preceding embodiment before, besides
the monomer(s) (B1) essentially no monomer (B2) is employed.
[0072] The mean polymerization temperature is appropriately in the range from 50 to 140°C,
preferably from 60 to 120°C and more preferably from 65 to 110°C.
[0073] Examples of suitable initiators (C) whose decomposition half-life in the temperature
range from 50 to 140°C is from 20 to 500 min are those described in
WO2023019153 on page 17, line 9, to page 18, line 25. The preferences given there are also the
same preferences used here for this present invention.
Particularly advantageous polymerization conditions can be established effortlessly
by precise adjustment of initiator (C) and polymerization temperature. For instance,
the preferred mean polymerization temperature in the case of use of tert-butyl peroxypivalate
is from 60 to 80°C, and, in the case of tert-butyl peroxy-2ethylhexanoate, from 80
to 100°C.
[0074] The inventive polymerization reaction can be carried out in the presence of, preferably
small amounts of, an organic solvent (D). It is of course also possible to use mixtures
of different solvents (D). Preference is given to using water-soluble or water-miscible
solvents.
[0075] When a solvent (D) is used as a diluent, generally from 1 to 40% by weight, preferably
from 1 to 35% by weight, more preferably from 1.5 to 30% by weight, most preferably
from 2 to 25% by weight, based in each case on the sum of the components (A), (B1),
optionally (B2), and (C), are used.
Examples of suitable solvents (D) include those described in
WO2023019153 on page 19, line 11, to page 20, line 22. The preferences given there are also the
same preferences used here for this present invention.
[0076] In the process according to the invention, polymer backbone (A), graft monomer (B1)
and, if appropriate, (B2), initiator (C) and, if appropriate, solvent (D) are usually
heated to the selected mean polymerization temperature in a reactor.
[0077] The reactor types to be employed for the polymerisation, means of post-polymerization,
means of polymerization such as temperatures, temperature ranges or tempertature profiules,
application of pressure or reduced pressure, purification, concentration etc and any
and all such means which can be adjusted, employed and/or applied are descried in
detail for the grafts polymer encompassed by this invention in the literature, specifically
in
WO2021160795 for graft I, in
WO2023019152 for graft II and
WO2023019153 for graft III. Those measures and preferences thereto are also explicitly encompassed
into this present invention as options and preferred embodiments.
According to the invention, the polymerization is carried out in such a way that described
in
WO2023019153 on page 20, line 25, to page 21, line 17. The preferences given there are also the
same preferences used here for this present invention.
[0078] From a theoretical point of view, each ester function of the polymeric sidechain
(B) may be replaced by an alcohol function (hydroxy group). In such a case, the polymeric
sidechain is fully hydrolyzed (saponified). It has to be noted that in case N-vinylpyrrolidone
is employed as further monomer, no hydrolyzation takes place at those units of the
polymeric sidechain (B) which originate from N-pyrrolidone employed as further monomer
(B).
[0079] The hydrolysis can be carried out by any method known to a person skilled in the
art. For example, the hydrolysis can be induced by addition of a suitable base, such
as sodium hydroxide or potassium hydroxide. However, in a most preferred embodiment
of this invention, the polymeric sidechains (B) are not hydrolyzed.
[0080] The graft polymers of the invention may contain a certain amount of ungrafted polymers
("ungrafted side chains") made of vinyl ester(s), e.g. poly vinyl acetate in case
only vinyl acetate is employed, and/or - when further monomers are employed - homo-
and copolymers of vinyl ester(s) with the other monomers. The amount of such ungrafted
vinyl acetate homo- and copolymers may be high or low, depending on the reaction conditions,
but is preferably to be lowered and thus low. By this lowering, the amount of grafted
side chains is preferably increased. Such lowering can be achieved by suitable reaction
conditions, such as dosing of vinyl ester and radical initiator and their relative
amounts and also in relation to the amount of backbone being present. This is generally
known to a person of skill in the present field.
[0081] The inventive graft polymers may be characterized by their degree of grafting (number
of graft sites of the polymeric sidechains (B) on the copolymer backbone (A)). The
degree of graft may be high or low, depending on the reaction conditions. Preferably,
the degree of grafting is low to medium, more preferably low. "Low" in this aspect
means that statistically less than 2 graft sites per 50 alkylene oxide units are present.
[0082] This adjustment of the degree of grafting and this amount of ungrafted polymers can
be used to optimize the performance in areas of specific interest, e.g. certain (e.g.
detergent-) formulations, application areas or desired cleaning etc. performance.
[0083] Inventive polymers have at least one of the following properties, preferably two
or more, to be successfully employed in the various fields of applications targeted
with this present invention:
- a) biodegradability of a certain level, such biodegradability of the graft polymer
being at least 15, preferably at least 20, preferably at least 25, preferably at least
30, preferably at least 35, even more preferably at least 40 % within 28 days when
tested under OECD301F (measurement method see also experimental section).
- b) Water-solubility of the polymers to a certain extent, to be able to employ the
polymers within the aqueous environment typically present in the fields of applications
as generally targeted with this present invention. Preferably inventive polymers should
exhibit a medium to good, more preferably a very good solubility in the environment
of an aqueous formulation as typically employed in such fields for the various kinds
of formulations, e.g. dish washing, automatic dish-washing, hard surface cleaning,
fabric cleaning, fabric care, cosmetic formulations etc.
- c) Viscosities of the polymer solutions should optionally be such that at reasonably
high solid concentrations of the polymer as to be handled in and after production
and to be provided to the user, which could be e.g. as a "pure" (then typically liquid)
product, dissolved in a solvent, typically an aqueous solution containing water and
organic solvents, only water or only organic solvents, the viscosity of such polymer
or polymer solution being in a range that allows typical technical process steps such
as pouring, pumping, dosing etc. Hence, the viscosities should be preferably in a
range of about up to less than 4000 mPas, more preferably up to 3500 mPas, even more
preferably up to 3000 mPas, such as up to 4500, 3750, 3250, 2750 or even 2600 or below
such as 2500, 2000, 1750, 1500, 1250, 1000, 750, 500, 250, 200, 150, or 100 mPas,
at concentrations of the polymer (based on the total solid content of the polymer
in solution, as defined by weight percent of the dry polymer within the total weight
of the polymer solution) of preferably at least 10 wt.%, more preferably at least
20, and even more preferably at least 40 wt.%, and most preferably at least 50 wt.%,
such as at least 60, 70, 80 or even 90 wt.%. The viscosity may be measured at either
25 °C or at elevated temperature, e.g. temperatures of 50 or even 60 °C. By this a
suitable handling of the polymer solutions in commercial scales is possible. It is
of course evident that depending on the amount of solvent being added the viscosity
is lower when the amount of solvent increases and vice versa, thus allowing for adjustment
in case desired. It is also evident that the viscosity being measured depends on the
temperature at which it is being measured, e.g. the viscosity of a given polymer with
a given solid content of e.g. 80 wt.% will be higher when measured at lower temperature
and lower when measured at a higher temperature. In a preferred embodiment the solid
content is in between 70 and 99 wt.%, more preferably in between 75 and 85 wt.%, with
no additional solvent being added but the polymer as prepared. In a more preferred
embodiment, the solid content is in between 70 and 99 wt.%, more preferably in between
75 and 95 wt.%, with no additional solvent being added but the polymer as prepared,
and the viscosity is lower than 3000 mPas, more preferably 3250, or even below 2750,
2600, 2500, 2000, 1750, 1500, 1250, 1000, 750, 500 or even 250 mPas, when measured
at 60 °C. The viscosity may be determined as generally known for such polymers, preferably
as described below in the experimental part.
[0084] To achieve these requirements, the following guidance can be given on how to achieve
such properties of the inventive polymers:
Biodegradability increases generally with at least one of the following conditions:
- lower molecular weight Mn of the backbone (A) compared to higher molecular weight;
- lower weight percentage of polymeric side chains (monomer B) being grafted onto the
backbone compared to higher weight percentages.
[0085] As further criteria of course the individual performance of a specific polymer needs
to be evaluated and thus ranked for each individual formulation in a specific field
of application. Due to the broad usefulness of the inventive polymers an exhaustive
overview is not possible, but the present specification and examples give a guidance
on how to prepare and select useful polymers of desired properties and how to tune
the properties to the desired needs. One such criteria for the area of home care and
especially fabric care of course it he performance upon washing, e.g. subjecting a
certain material exhibiting stains of certain materials to a defined washing procedure.
[0086] The examples give some guidance for the application for washing of fabrics, i.e.
the general area of fabric care.
[0087] Depending on the individual needs for a polymer exhibiting a defined degree of biodegradation,
water solubility and viscosity (i.e. handling properties) the general and specific
teachings herein - without being intended to be limited to the specific examples being
given - will guide on how to obtain such polymer.
The modified polyalkyleneimine / polyamine (PAI / PA):
[0088] The modified polyalkyleneimine / polyamine (PAI / PA) comprises a polyalkyleneimine
/ polyamine (PAI / PA) core, and at least one side chain attached to at least one
NH-functionality of the polyalkyleneimine / polyamine (PAI / PA) core, such chain
consisting of moieties stemming from the polycondensation or polyaddition of at least
one of the following further monomers
(D) at least one lactone and/or at least one hydroxy carbon acid, and/or
(E) at least one alkylene oxide being selected from C2 to C22-alkylene oxides, preferably C2 to C6, more preferably C2, C3 and/or C4,
wherein the order of D and E within the side chains can be any order such as random,
block or statistical distribution, with block order being preferred, and
wherein the amount of D is from 0,5 to 15 based on mol equivalents per NH-functionality,
and
wherein the amount of E is within 10 to 100 based on mol equivalents per NH-functionality.
wherein the polyalkyleneimine / polyamine (PAI / PA) core comprises from 2 to 8 Nitrogen
atoms.
[0089] In principle, the polyalkyleneimine / polyamine (PAI / PA) core generally may be
linear or branched, with the branching forming a tertiary amino group, and branches
may be (i) relatively short alkylene amino groups as such (e.g., -(CH
2)
3-NH
2 groups) up to very long side chains which may contain further amino-groups being
similarly branched etc, thus leading to highly branched structures such as the typical
highly branched polyethylene imine (PEI) known to date, or (ii) hydrocarbon units
not bearing further amino groups.
[0090] Within the context of the present invention, the term "polyalkylene imine" (PAI)
differs from the corresponding term "polyamine" (PA) especially in respect of the
branching of the compounds as such as employed in the first step (to obtain an modified
polyamine or modified polyalkylene iminie) as educt or within the backbone of the
corresponding modified alkoxylated compounds as such as obtained within the modification
steps (i.e. the following reactions with alkylene oxides and/or lactones and/or their
mixtures) within the process to produce them. Polyethylene imines (PEI) are PAI resulting
from the polycondensation of ethyleneimine only.
[0091] Whereas polyamines (PA) in the context of the present invention are (predominantly)
linear compounds (in respect of its backbone without consideration of any alkoxylation),
containing primary and/or secondary amino moieties
but no tertiary amino moieties within its backbone, the corresponding polyalkylene imines are, according to the
present invention, (predominantly) branched molecules containing (in respect of its
backbone without consideration of any alkoxylation), in addition to the primary and/or
secondary amino moieties, mandatorily tertiary amino moieties, which cause the branching
of the (linear) main chain into several side chains within the polymeric backbone
(basic skeleton).
[0092] For the purpose of this invention, the polyalkyleneimine / polyamine (PAI / PA) core
comprises on average from 2 to 6 Nitrogen atoms, preferably from 2 to 4 Nitrogen atoms,
more preferably from 2 to 3 Nitrogen atoms, most preferably 2 Nitrogen atoms. Without
wishing being bound by theory, modified polyalkyleneimine / polyamine (PAI / PA) polymers
with lower average number of Nitrogen atoms typically show better biodegradability.
[0093] Polyalkylene imines, both as backbone and as modified alkoxylated compounds are thus
compounds falling under the definition of general formula (I),

wherein z is an integer of at least 1 and/or y is an integer of at least one and at
least one of the variables (residues) E
1 is C
1-C
18-alkyl. R is identical or different, linear or branched C
2-C
12 alkylene radicals, preferably C
2-C
6 alkylene radicals, more preferably C
2-C
4 alkylene radicals. In contrast to that, polyamines, both as backbone and as modified
alkoxylated compounds, are those compounds of formula (I), wherein z is 0 and E
1 is hydrogen, or wherein both z and y are 0.
[0095] For the sake of completeness, it is indicated that the variable B indicating the
branching of the polyalkylene imine backbone of compounds according to general formula
(I) contains at least one fragment with at least one further amino moiety such as
-[-NE
1-R]
y, H
2N-R or combinations thereof, including a two times, three times or even higher degree
of branching. It has to be noted that in contrast to the definition of the variable
B, the variable E
1 with C
1-C
18-alkyl also provides a branching of the respective backbone and, by consequence, another
type of tertiary amino moiety, but in contrast to the definition of the variable B,
the variable E
1 does not contain any further amino moiety. However, none of the tertiary amino moieties
are present in the backbone of polyamine compounds. The degree of branching may be
determined, for example, by NMR-spectroscopy such as
1H-NMR or preferably
13C-NMR.
[0096] Within the context of the present invention, the term "polyalkylene imine backbone"
relates to those fragments of the inventive modified alkoxylated polyalkylene imines
which are not alkoxylated and not further modified. The polyalkylene imine backbone
is employed within the present invention as an educt in step a) to be reacted first
with at least one first lactone (LA 1) or hydroxy carbon acid (HA1) in order to obtain
a first intermediate (I1), followed by step b), wherein said first intermediate (I1)
is reacted with at least one alkylene oxide (AO) in order to obtain a second intermediate
(I2). Afterwards, said second intermediate (I2) is reacted with at least one second
lactone (LA2) and/or a second hydroxy carbon acid (HA2) in order to obtain the inventive
modified alkoxylated polyalkylene imines. Polyalkylene imines as such (backbones or
not alkoxylated compounds) are known to a person skilled in the art.
[0097] Within the context of the present invention, the term "polyamine backbone" relates
to those fragments of the inventive modified alkoxylated polyamines which are not
alkoxylated and not further modified. The polyamine backbone is employed within the
present invention as an educt in step a) to be reacted first with at least one first
lactone (LA1) or hydroxy carbon acid (HA1) in order to obtain a first intermediate
(I1), followed by step b), wherein said first intermediate (I1) is reacted with at
least one alkylene oxide (AO) in order to obtain a second intermediate (I2). Afterwards,
said second intermediate (I2) is reacted with at least one second lactone (LA2) and/or
a second hydroxy carbon acid (HA2) in order to obtain the inventive modified alkoxylated
polyamines. Polyamines as such (backbones or not alkoxylated compounds) are known
to a person skilled in the art.
[0098] Within the context of the present invention, the term "NH-functionality" is defined
as follows: In case of defined organic amines, such as di- and oligo amines like BAPMA,
N4-amine or 1,6-hexamethylene diamine, the structure itself gives information about
the content of primary, secondary and tertiary amines. A primary amino group (-NH
2) has two NH- functionalities, a secondary amino group only one NH-functionality,
and a tertiary amino group, by consequence, has no reactive NH-functionality. In case
of (predominantly) branched polyethylene imines, such as those as obtained from polymerization
of the monomer ethylene imine (C
2H
5N), the respective polymer (polyethylene imine, PEI) contains a mixture of primary,
secondary and tertiary amino groups. The exact distribution of primary, secondary
and tertiary amino groups can be determined as described in
Lukovkin G.M., Pshezhetsky V.S., Murtazaeva G. A.: Europ. Polymer Journal 1973, 9,
559-565 and
St. Pierre T., Geckle M.: ACS Polym. Prep. 1981, 22, 128-129, or by determination of the primary, secondary and tertiary amino number, according
to DIN 16945. In case of the modification with lactone or hydroxy carbon acids and
alkylene oxides, this information is then used to calculate the total amount of NH
functionalities in the polyalkylene imine, which serves as the basis for the amount
of modification reagents to be employed in the reaction.
[0099] For the purpose of the present invention, the term "integer" - as defined, for example,
for the number of the different repeating units such as the variables m, n and o of
the residue according to general formula (IIa) - relates to the average number of
each of the different repeating units of that specific residue, i.e., to the number
of each of the different repeating units of the most frequent residue among all existing
specific residues according to general formula (IIa), as obtained by the respective
synthesis/polymerization conditions. It is clear to the person skilled in the art
that a polymer composition usually contains a statistically distributed mixture of
individual polymers or a statistically distributed mixture of individual residues
according to, for example, general formula (IIa), respectively. It is therefore clear
to a person skilled in the art that within such a statistically distributed mixture
of individual residues according to general formula (IIa) the individual residues
as such may differ in respect of the numbers of said repeating units. The same holds
true for any other specific residue according to the present invention such as the
residues according to general formulas (IIb) or (IIc). The average number of repeating
units can be determined by analytical methods such as NMR and GPC. Preferably, within
the embodiment of the present invention, the determination of the average number of
repeating units, such as the variables m, n and o in the residue according to general
formula (IIa), is performed by closely monitoring the conversion rates of each of
the synthetical steps a) - c) using
13C-NMR-spectroscopy and/or
1H-NMR-spectroscopy. However, as the term "integer" denotes the number of repeating
units, and these numbers are a results from a statistical distribution which stems
from the way the reaction is pursued (amounts, relative amounts, duration etc), it
is also clear that the number not necessarily is an "integer" in mathematical terms,
but can be in principle any number between zero and the maximum amount allowed, including
natural numbers but also decimal numbers.
[0100] Polyalkyleneimine / polyamine (PAI / PA) may be predominantly linear, such as at
least to 95% linear, and preferably are essentially linear ("essentially linear" being
defined herein as comprising less than 1%, preferably less than 0,5% of tertiary nitrogen
atoms), such as completely linear ("completely linear" being defined herein as containing
no detectable amounts of tertiary amines). When tertiary nitrogen atoms are present,
those nitrogen atoms are preferably substituted with hydrocarbon units only, more
preferably with C
1-C
4-alkyl-groups, most preferably with C
1- and/or C
2-alkyl, most preferably C
1-alkyl only. Most preferably, such tertiary nitrogen atoms are essentially not present
and thus the PAI are essentially linear.
[0101] In another embodiment, polyalkyleneimine / polyamine (PAI / PA) may be branched,
such as moderately to highly branched or even hyperbranched, as the known PEI-structures
which typically are highly branched or even hyperbranched.
The degree of branching may be determined, for example, by NMR-spectroscopy such as
1H-NMR or preferably
13C-NMR.
[0102] The amine number for primary and secondary, and tertiary amines is determined in
accordance with the standard DIN EN ISO 9702.
[0103] Typically, the biodegradation of polyalkyleneimine / polyamine (PAI / PA) itself
is depending on the molecular weight: the higher the molecular weight, biodegradability
decreases quickly. For this invention, it is preferred that the polyalkyleneimine
/ polyamine (PAI / PA) has a MW less than 600, preferably less than 550
[0104] An advantage of the modified alkoxylated compounds according to the present invention
can be seen in their properties, which can be tuned in hydrophilicity/hydrophobicity
to achieve in principle all properties from hydrophobic over amphiphilic to hydrophilic;
this is especially due to the employment of alkylene oxides and the proper selection
of hydrophilic and more hydrophobic alkylene oxides, their relative amounts and their
order, by which one or more blocks or a totally random structure or a mixture of random
and block structures can be created, thus achieving in principle each and every degree
of hydrophilicity/ hydrophobicity/amphiphillicity as desired.
[0105] By inclusion of ester-groups into those alkylene oxide chains a "linker" is introduced
which is generally accepted as having a lower resistance to hydrolysis; thus, these
linker positions are prone to hydrolytic attack and thus help to "cut" the chains
into smaller sub-parts, and by this help to speed up the total biodegradation in terms
of speed and also of total biodegradability of the compounds.
Further definitions for Substitutions
[0106] For the purpose of the present invention, the expression / term "modified" relates
to the presence of a linker based on lactones or hydroxyl carbon acids within the
inventive modified alkoxylated polyalkylene imines and modified alkoxylated polyamines
(obtainable by a process comprising the step a)), as well as the presence of further
(predominately) hydrophobic polyester blocks based on lactones or hydroxyl carbon
acids obtained in step c), in addition to the alkylene oxide blocks obtained in step
b) By consequence, at the periphery of several residues, such as residues according
to formula (IIa) expressed by the variables R
3 and m, fragments with (predominately) hydrophobic polyester blocks are obtained.
Those fragments with (predominately) hydrophobic polyester blocks lead to the amphiphilic
nature and thus to excellent cleaning properties of the inventive polymers in detergent
applications.
[0107] The term "polymer", "polymer of the invention" or "inventive polymer", as used herein,
refers to modified alkoxylated polyalkylene imines as described below and/or in the
appended claims.
[0108] For the purposes of the present invention, definitions such as C
1-C
22-alkyl, as defined below for, for example, the radical R
2 in formula (IIa), mean that this substituent (radical) is an alkyl radical having
from 1 to 22 carbon atoms. The alkyl radical can be either linear or branched or optionally
cyclic. Alkyl radicals which have both a cyclic component and a linear component likewise
come within this definition. The same applies to other alkyl radicals such as a C
1-C
4-alkyl radical. Examples of alkyl radicals are methyl, ethyl, n-propyl, sec-propyl,
n-butyl, sec-butyl, isobutyl, 2-ethylhexyl, tert-butyl (tert-Bu/t-Bu), pentyl, hexyl,
heptyl, cyclohexyl, octyl, nonyl, decyl or dodecyl.
[0109] The term "C
2-C
22-alkylene" as used herein refers to a saturated, divalent straight chain or branched
hydrocarbon chains of 2, 3, 4, 5, 6, 10, 12 or up to 22 carbon atoms, examples including
ethane-1,2-diyl ("ethylene"), propane-1,3-diyl, propane-1,2-diyl, 2-methylpropane-1,2-diyl,
2,2-dimethylpropane-1,3-diyl, butane-1,4-diyl, butane-1,3-diyl (= 1-methylpropane-1,3-diyl),
butane-1,2-diyl ("1,2-butylene"), butane-2,3-diyl, 2-methyl-butan-1,3-diyl, 3-methyl-butan-1,3-diyl
(= 1,1-dimethylpropane-1,3-diyl), pentane-1,4-diyl, pentane-1,5-diyl, pentane-2,5-diyl,
2-methylpentane-2,5-diyl (= 1,1-dimethylbutane-1,3-diyl) and hexane-1,6-diyl.
[0110] Other such typical abbreviations such as "C2-C22 alkylene oxides" and the like have
their ordinary meaning as used in this field of organic chemistry.
[0111] The term "C
5-C
10-cycloalkylene" as used herein refers to saturated, divalent hydrocarbons of 5, 6,
7, 8, 9 or 10 carbon atoms wherein all or at least a part of the respective number
of carbon atoms form a cycle (ring). In case not all of the respective number of carbon
atoms form a cycle, such remaining carbon atoms (i. e., those carbon atoms not forming
a cycle) form a methane-1,1-diyl ("methylene") fragment or an ethane-1,2-diyl ("ethylene")
fragment of the respective C
5-C
10-cycloalkylene radicals. One of the two valencies of said respective methylene or
ethylene fragments is bound to a neighbouring nitrogen atom within general formula
(I), whereas the second valency of said fragments is bound to the cyclic fragment
of said C
5-C
10-cycloalkylene radical.
[0112] Expressed in other words, a C
5-C
10-cycloalkylene radical may comprise, in addition to its cyclic fragment, also some
non-cyclic fragments building a bridge or a linker of the cyclic fragment of the C
5-C
10-cycloalkylene radical to the neighbouring nitrogen atom within general formula (I).
The number of such carbon linker atoms is usually not more than 3, preferably 1 or
2. For example, a C
7-cycloalkylene radical may contain one C
6-cycle and one C
1-linker.
[0113] The respective hydrocarbon cycle itself may be unsubstituted or at least monosubstituted
by C
1-C
3-alkyl. It has to be noted that the carbon atoms of the respective C
1-C
3-alkyl substituents are not considered for determination of the number of carbon atoms
of the C
5-C
10-cycloalkylene radical. In contrast to that, the number of carbon atoms of such a
C
5-C
10-cycloalkylene radical is solely determined without any substituents, but only by
the number of carbon atoms of the cyclic fragment and optionally present carbon linker
atoms (methylene or ethylene fragments).
[0114] Examples for C
5-C
10-cycloalkylene include cyclopentane-1,2-diyl, cyclohexane-1,2-diyl, cyclohexane-1,3-diyl,
cyclohexane-1,4-diyl, 3-(methane-1,1-diyl)-cyclohexane-1,3-diyl, cycloheptane-1,3-diyl
or cyclooctane-1,4-diyl, each of the aforementioned radicals may be at least monosubstituted
with C
1-C
3-alkyl.
[0115] It is preferred that the respective C
5-C
10-cycloalkylene radical is employed as a mixture of two or more individual cycloalkylene
radicals having the same ring size. It is particularly preferred to employ a mixture
of cyclohexane-1,3-diyl monosubstituted with methyl in position 2 or 4, respectively,
of the cycle. The ratio of the two compounds is preferably in a range of 95 : 5 to
75 : 25, most preferably about 85 : 15 (4-methyl versus 2-methyl).
[0116] 3-(methane-1,1-diyl)-cyclohexane-1,3-diyl is a preferred example for a C
5-C
10-cycloalkylene radical having a non-cyclic fragment in addition to its cyclic fragment.
For this specific case, the non-cyclic fragment is a C
1-linker and the cyclic fragment is a C
6-cycle resulting in a C
7-cycloalkylene radical. 3-(methane-1,1-diyl)-cyclohexane-1,3-diyl may also be substituted
with at least one C
1-C
3-alkyl, preferably with three methyl groups, in particular 3,5,5-trimethyl. The latter
one is a fragment of isophorone diamine, which may be employed as backbone with general
formula (I).
[0117] For the purposes of the present invention, the term "aralkyl" or "C
7-C
22-aralkyl", respectively, as defined below for, for example, the radical R
2 in formula (IIa), means that the substituent (radical) is an aromatic ("ar") combined
with an alkyl substituent ("alkyl"). The aromatic "ar" part can be a monocyclic, bicyclic
or optionally polycyclic aromatic. In the case of polycyclic aromatics, individual
rings can optionally be fully or partially saturated. Preferred examples of aryl are
phenyl, naphthyl or anthracyl, in particular phenyl. The sum of the carbon atoms of
the aromatic and the alkyl fragment is a radical having from 7 to 22 carbon atoms.
[0118] The term "-(CO)-C
1-C
22-alkyl" as used hereinafter, for example, within the definition for the radical R
2 in formula (IIa) means that this substituent contains a carbonyl group (CO) bound
to an alkyl radical having 1 to 22 carbon atoms as defined above. The alkyl radical
can be either linear or branched or optionally cyclic. Alkyl radicals which have both
a cyclic component and a linear component likewise come within this definition. The
same applies to the definitions of the term "-(CO)-C
7-C
22-aralkyl" in respect of a carbonyl group (CO) bound to a radical having an aromatic
and an alkyl fragment with a sum of 7 to 22 carbon atoms as defined above.
[0119] For the purposes of the present invention, definitions such as C
2-C
30-alkenyl, as defined below, for example, as part of the term "-(CO)-C
2-C
30-alkenyl" of the radical R
2 in formula (IIa), mean that this part of the substituent (radical) is an alkenyl
radical having from 2 to 30 carbon atoms. This carbon radical is preferably monounsaturated
but can optionally also be doubly unsaturated or multiply unsaturated. As regards
linearity, branches and cyclic constituents, what has been said above for C
1-C
30-alkyl radicals applies analogously. C
2-C
30-alkenyl is, for the purposes of the present invention, preferably vinyl, 1-allyl,
3-allyl, 2-allyl, cis- or trans-2-butenyl, ω-butenyl. The term "-(CO)-C
2-C
30-alkenyl" in turn relates to a substituent containing a carbonyl group (CO) bound
to such an alkenyl radical having from 2 to 30 carbon atoms as defined above.
[0120] The term "unsubstituted or at least monosubstituted C
1-C
22-alkyl, C
7-C
22-aralkyl, -(CO)-C
1-C
22-alkyl, -(CO)-C
2-C
30-alkenyl and/or -(CO)-C
7-C
22-aralkyl" as defined below, for example, in R
2 in formula (IIa) means that each of the mentioned/listed radicals (substituents)
such as C
1-C
22-alkyl or -(CO)-C
7-C
22-aralkyl may either be unsubstituted or at least monosubstituted with the specific
substituents as defined in the (following) context. For the sake of completeness it
is also indicated that a person skilled in the art knows that the mentioned substituents
replace a hydrogen atom of the respective radicals (substituents) such as C
1-C
22-alkyl or -(CO)-C
7-C
22-aralkyl. In case the substituents are selected from -COOH or a salt thereof, the
respective salts are known to the skilled person. Preferably, the salts are selected
from alkali salts such as sodium or potassium salts, in particular a sodium salt (-COONa).
[0121] The modification of the modified polyalkyleneimine / polyamine (PAI / PA):
The modified polyalkyleneimine / polyamine (PAI / PA) may comprise side chains which
are attached to nitrogen atoms of the polyalkyleneimine / polyamine (PAI / PA). The
side chains may be - and preferably are - attached by way of a polycondensation or
polyaddition reaction. The side chains are made up from C
2-C
22-alkylene oxides, lactones and/or hydroxy carbon acids. Typically, a side chain comprises
at least one alkylene oxide (AO) and at least one lactone (LA) and/or at least one
hydroxy acid (HA). The (poly)condensation or (poly)addition reaction to prepare a
side chain comprising AO, LA and HA is - by way of example for the preparation of
the side chains in general - typically done by reacting the polyalkyleneimine / polyamine
(PAI / PA) with the at least one AO and the at least one LA and/or HA either i) in
a mixture of adding all ingredients employed at the very same time or at least shortly
after each other with a preferably as short as possible timelag, ii) by adding first
either the AO or the LA or the HA and then the second ingredient and then the third
to obtain blocks of AO, LA and HA, iii) by adding one or two ingredients as defined
for method i) before and the remaining two or one ingredient(s) according to method
ii) as defined before. It is of course also possible to repeat reactions with further
amounts of the same ingredient type AO, LA and/or HA at a later point in time, thereby
creating block structures.
[0122] Preferably, a side chain comprises more than one, more preferably more than two,
even more preferably more than 3 units per NH-functionality of the polyalkyleneimine
/ polyamine (PAI / PA) stemming from AO, and at least 0,5 units per NH-functionality.
All such numbers are numbers "on average" meaning that such numbers refer to the average
number for such unit per NH-functionality calculated based on all NH-functionalities
of a polyalkyleneimine / polyamine (PAI / PA).
[0123] Additionally, it has to be noted within the context of the process according to the
present invention that those primary amino moieties of the respective backbone, which
are reacted first with at least one lactone and/or at least one hydroxy carbon acid
are transferred into an amido moiety wherein one of the originally two hydrogen atoms
of the respective primary amino moiety is replaced by a fragment originating from
the respective lactone or hydroxy carbon acid, whereas the second hydrogen atom of
the primary amino moiety of the backbone does not get substituted by this reaction.
Beyond that, such a second hydrogen atom of the primary amino moiety of the backbone
does also not become substituted within the further reaction steps, e.g., further
reactions with AO, LA and/or HA.
Statistical Reactions and thus statistical Distributions
[0124] It is to be emphasized that the reactions leading to the modified polyalkyleneimine
/ polyamine (PAI / PA) are statistical reactions, meaning there is never just one
chemically exactly defined compound present, but an inventive modified polyalkyleneimine
/ polyamine (PAI / PA) always is a mixture of slightly deviating structures, all stemming
from the same reaction within one reaction space; the difference of those structures
clearly stemming from the facts that no reaction proceeds in exactly the same way
and the same speed on all functional units, especially as the chemical reactivities
of the functional units - here mainly those of the NH-functionalities, differs according
to their environment, meaning that a primary amino group reacts differently than a
secondary amine and that differently compared to a tertiary amino group (specifically
in terms of reaction with a lactone and/or a hydroxy carbon acid, as described above),
and also the chemical environment of those three principal groups may be different
in the monomers employed; this leads in an overall view to slightly deviating structures
being present, and thus any modified polyalkyleneimine / polyamine (PAI / PA) of this
invention being defined as in the various embodiments, and exemplified in the examples
never is just one chemical compound, but always a mixture of slightly deviating compounds,
having a statistical distribution. As the reactivities of those groups are not differing
by a large extent, the deviation is relatively small. Hence, defining a modified polyalkyleneimine
/ polyamine (PAI / PA) by their monomers and process of production (i.e. order of
reaction steps) is a viable way of defining the structures. Also, defining the composition
of the side chains by average numbers based on the numbers of NH-functionalities being
present in the modified polyalkyleneimine / polyamine (PAI / PA) - such number of
functionalities being themselves an average number due to this factual mixture - is
a useful way of defining the overall composition of any mixture herein defined as
"a modified polyalkyleneimine / polyamine (PAI / PA)".
[0125] Therefore, unless otherwise indicated, the values, ranges and ratios given in the
specification, the numbers for a, b, c, d and e, the number of NH-functionalities,
and the molecular weight (Mn) relate to the number average values of the mixture obtained
as modified polyalkyleneimine / polyamine (PAI / PA) containing individual, slightly
from each other deviating chemical structures of several modified polyalkyleneimine
/ polyamine (PAI / PA) - compounds, with "the modified PAI/PA" defining this mixture
being the result from the preparation method. As known in polymer science, the weight-average
molecular weight (Mw) is then a measure for the (in)homogeneity within the mixture
of different species in "the modified polyalkyleneimine / polyamine (PAI / PA)".
[0126] Suitable lactones and/or hydroxy carbon acids can be aliphatic, cycloaliphatic or
aromatic.
[0127] Particularly suitable aromatic hydroxy carbon acids are hydroxy-substituted benzoic
acids and naphthalene carboxylic acids, such as p-hydroxyethyl benzoic acid and 2-hydroxynaphthalene-6-carboxylic
acid. Preference is given to aliphatic hydroxy carbon acids, especially to those with
hydroxyl groups in the ω position, and their lactones. In general, the aliphatic hydroxy
carbon acids have from 1 to 22 alkylene radicals, preferably from 2 to 10 alkylene
radicals, more preferably from 2 to 5 alkylene radicals. The alkylene radicals may
be linear or branched. Examples which may be mentioned are glycolic acid, lactic acid
and its lactide, gamma-hydroxybutyric acid and gamma-butyrolactone, delta-hydroxyvaleric
acid and gamma- and delta-valerolactone, epsilon-hydroxycaproic acid and epsilon-caprolactone,
12-hydroxystearic acid and ricinoleic acid, and also mixtures, especially including
naturally occurring acids. Preferably, glycolic acid, lactic acid, epsilon-caprolactone
or lactide, or mixtures thereof, are employed, even more preferably epsilon-caprolactone.M
[0128] Modified polyalkyleneimine / polyamine (PAI / PA) according to this invention thus
comprises at least one of the following side chain-structures:
- i) [PAI/PA]-N-(E1)a-(D1)d-(E2)b-(E3)c
- ii) [PAI/PA]-N-(D1)d-(E2)b-(E3)c
- iii) [PAI/PA]-N-(E1)a-(D1)d-(E2)b
- iv) [PAI/PA]-N-(D1)d-(E2)b
- v) [PAI/PA]-N-(E1)a-(D1)d-(E2)b-(D2)e
- vi) [PAI/PA]-N-(D1)d-(E2)b-(D2)e
with (E1), (E2), (E3) each denoting sub-units each being independently from each other
composed of monomers which is/are at least one alkylene oxide, preferably a single
alkylene oxide,
with (D1) and (D2) each denoting sub-units each being independently from each other
composed of monomers which is/are at least one lactone(s) and/or hydroxy carbon acid(s),
preferably a single lactone and/or hydroxy carbon acid,
with a, b, c, d and e defining the total average number of individual repeating units
within each sub-unit (E1), (E2, (E3), (D1) and (D2)
preferably the side chains being selected from i), ii), iii) and iv), more preferably
from i) and ii), most preferably i),
and with the variables being based on average mol equivalents per NH-functionality
of the modified polyalkyleneimine / polyamine (PAI / PA)as follows:
- a 0.5-2, preferably 0.8-1.5, and/or
- b 10 to 40, preferably 15 to 35, and/or
- c 5 to 40, preferably 10 to 35, and/or
- d 0.5-5, preferably 1.0-3.0, and/or
- e 2-10, preferably 2-6;
preferably
D1 is a linear or branched C3-C11 aliphatic lactone, most preferably caprolactone, and/or a hydroxy carbon acid, most
preferably lactic acid and/or glycolic acid; in one preferred embodiment D1 is caprolactone;
D2 is a linear or branched C3-C11 aliphatic lactone, most preferably caprolactone, and/or a hydroxy carbon acid, most
preferably lactic acid and/or glycolic acid; in one preferred embodiment D2 is caprolactone;
E1 is preferably C2-C5-AO, most preferably EO, PO and/or BuO;
E2 is C2-C5-AO containing more than 50 wt% EO, preferably more than 90 wt% EO, most preferably
100 wt% EO;
E3 is C2-C5-AO containing more than 50 wt% PO and/or BuO, preferably more than 90 wt% PO and/or
BuO, most preferably 100 wt% PO and/or BuO; in one preferred embodiment, E3 is 100
wt% PO.
[0129] It is to be emphasized that it is a preferred embodiment to employ the various AOs
denoted in the various preferred embodiments as E1, E2 and E3, and the lactones/hydroxy
carbon acids denoted in various preferred embodiments as D1 and D2 in a stepwise manner.
Such stepwise manner is to be understood that
- by way of example using structural order "i) [PAI/PA]-N-(E1)a-(D1)d-(E2)b-(E3)c" -
to obtain such structural order the following reaction steps are to be employed:
A modified polyalkyleneimine / polyamine (PAI / PA) as defined in this invention is
employed and reacted first with AO(s) represented by E1, then in a second reaction
with lactone(s)/hydroxy acid(s) represented by D1, then in a third reaction with AO(s)
represented by E2, and in a fourth reaction with AO(s) represented by E3.
[0130] The conversion rate of each reaction is monitored: Only when the previous reaction
(in this example: E1 as the first reactant reacting with polyalkyleneimine / polyamine
(PAI / PA)) has proceeded to a conversion rate of at least 90%, preferably at least
95%, more preferably at least 99%, and even more preferably at least 99,5 % or even
more has been achieved, the next reactant (in this example: D1 as the second reactant)
is to be added which in turn is also monitored for its conversion rate to detect when
this next reaction has proceeded to a conversion rate of at least 90%, preferably
at least 95%, more preferably at least 99%, and even more preferably at least 99,5
% or even more has been achieved, then the even next reaction (in this example: E2
as the third reactant) is to be added - and so on until all reactants have been reacted
and the reaction of the last reactant added has proceeded to a conversion rate of
at least 90%, preferably at least 95%, more preferably at least 99%, and even more
preferably at least 99,5 % or even more has been achieved. All other structural orders
as previously and hereinafter defined are performed in this defined manner, leading
- on statistical average - to a defined structural order directly derived from the
way such reaction is performed.
[0131] The conversion rate of each of the respective steps can be determined according to
methods known to the skilled person, such as NMR-spectroscopy, such as
13C-NMR-spectroscopy and/or
1H-NMR-spectroscopy.
[0132] In a preferred embodiment the sub-units are composed as follows:
- i) E1 is PO and/or BuO; and/or
- ii) E2 is EO; and/or
- iii) E3 is PO; and/or
- iv) D1 is caprolactone; and/or
- v) D2 is caprolactone,
preferably at least two, more preferably at least three, even more preferably at least
four, and most preferably all options i) to v) being interlinked with "and" and thus
being required features.
[0133] IN another preferred embodiment the sub-units are composed on average as follows:
- i) E1 being 0.8-1.5 PO and/or BuO; and/or
- ii) E2 being 15 to 35 of EO; and/or
- iii) E3 being 10 to 35 of PO; and/or
- iv) D1 being 1.0-3.0 caprolactone; and/or
- v) D2 being 2-6 caprolactone,
with all numbers being mol per NH-functionality of the polyalkyleneimine / polyamine
(PAI / PA) (whatever is employed as the "core"),
preferably at least two, more preferably at least three, even more preferably at least
four, and most preferably all options i) to v) being interlinked with "and" and thus
being required features.
[0134] In a further preferred embodiment of the embodiments before, at least 50 %, preferably
at least 60% and most preferably at least 80%, even more preferably at least 90, and
most preferably at least 95% of all side chains attached to the NH-functionalities
of one specific modified polyalkyleneimine / polyamine (PAI / PA) (whatever is employed
as the "core") have the same structural order, such structural order as being generally
defined as "structural orders" as i), ii), iii), iv), v) or vi) in the context of
"Modified polyalkyleneimine / polyamine (PAI / PA) according to this invention..."
as defined above.
[0135] Without wishing being bound by the following explanation, a rationale exists to explain
the resulting structures of the polyalkyleneimine / polyamine (PAI / PA) and the modified
polyalkyleneimine / polyamine (PAI / PA): Due to the fact that the reactions in questions
necessarily employed to prepare those structural orders of the side chains, and thus
to prepare the specific modified polyalkyleneimine / polyamine (PAI / PA), are reactions
of quite reactive species which can lead under suitable conditions to almost complete
and even "essentially complete" conversions of almost 100 % if not even 100%, the
statistical deviation of the composition of the mixture of "the PAI/PA" in question
is not that high, which in turn means that the structural order of the side chains
do not show much deviation. Thus, it is a reliable assumption which can in principle
being proven by sophisticated and thus time-consuming and expensive analytical means
- such as multi-dimensional NMR-analyses - and thus it is generally accepted that
such deviation exists; hence, no "specific modified PAI/PA" will be "just one chemical
compound of a clearly defined chemical structure", but clearly will consist of a a)
mixture of slightly differing compounds, such differences lying in b) slight deviations
already in the structure of compound making up "the (unmodified) PAI/PA" being employed
for the further modification steps, and c) the slight deviations in the structural
orders of the side chains attached by way of d) multi-step condensation reactions
due to e) variations in the chemical reactivities of the NH-functionalities, f) slight
differences in the reactivities of employed AO, LA and HA due to their structure and
g) due to their reactivities towards the slightly differing reactivities NH-functionalities,
and h) due to slight inhomogeneities occurring in a commercial scale process. All
of those factors a) to h) - to just mention a few important ones - lead to a "specific
modified PAI/PA" which is not one specific chemical compound but in fact a mixture
of slightly differing compounds having an overall very similar chemical structure;
thus, such structure is best described by average numbers for the variables and percentages
for the amounts of the dominating structural order.
[0136] The modified PAI/PA as detailed herein may be further modified by quaternization
using standard means, including protonation by pH-adjustment or permanent quaternization
by standard means such as alkylation using standard reactants, preferably by alkylation,
to a degree of from 5 to 100, preferably up to 95, more preferably up to 70, even
more preferably up to 50 percent of all nitrogen-atoms within the PAI/PA. It is well-known
to a person of skill in the art that such PAI/PA -structures and such modified PAI/PA
-structures can be quaternized using standards means, due to their in principle chemical
similarity with already known structures of this general type, and the known ability
to modify those known structures by quaternization. Clearly, also the present structures
described herein as PAI/PA and modified PAI/PA can be quaternized as well.
[0137] A suitable degree of quaternization is up to 100%, in particular from 5 to 95%. The
quaternization is conducted preferably by introducing C
1-C
22-alkyl groups, C
1-C
4-alkyl groups and/or C
7-C
22-aralkyl groups and may be undertaken in a customary manner by reaction with corresponding
alkyl halides and dialkyl sulfates. The quaternization may be advantageous in order
to adjust the inventive modified PAI/PA to the particular composition such as laundry
compositions in which they are to be used, and to achieve better compatibility and/or
phase stability of the formulation.
[0138] The quaternization of the inventive modified PAI/PA is achieved preferably by introducing
C
1-C
22 alkyl, C
1-C
4-alkyl groups and/or C
7-C
22 aralkyl, aryl or alkylaryl groups and may be undertaken in a customary manner by
reaction with corresponding alkyl-, aralkyl - halides and dialkylsulfates, as described
for example in
WO 09/060059.
[0139] Quaternization can be accomplished, for example, by reacting an inventive modified
PAI/PA with an alkylation agent such as a C
1-C
4-alkyl halide, for example with methyl bromide, methyl chloride, ethyl chloride, methyl
iodide, n-butyl bromide, isopropyl bromide, or with an aralkyl halide, for example
with benzyl chloride, benzyl bromide or with a di-C
1-C
22-alkyl sulfate in the presence of a base, especially with dimethyl sulfate or with
diethyl sulfate. Suitable bases are, for example, sodium hydroxide and potassium hydroxide.
[0140] The amount of alkylating agent determines the amount of quaternization of the amino
groups in the polymer, i.e., the amount of quaternized moieties.
[0141] The amount of the quaternized moieties can be calculated from the difference of the
amine number in the non-quaternized amine and the quaternized amine. The amine number
can be determined according to the method described in DIN 16945.
[0142] The quaternization can be carried out without any solvent. However, a solvent or
diluent like water, acetonitrile, dimethylsulfoxide, N-methylpyrrolidone, etc. may
be used. The reaction temperature is usually in the range from 10°C to 150°C and is
preferably from 50°C to 100°C.
[0143] The quaternization may be advantageous in order to adjust the modified or unmodified
PAI/PA to the particular composition such as laundry compositions in which they are
to be used, and to achieve better compatibility and/or phase stability of the formulation

Fibrous Water-soluble Unit Dose Article.
[0311] As used herein, the phrases "water-soluble unit dose article," "water-soluble fibrous
structure", and "water-soluble fibrous element" mean that the unit dose article, fibrous
structure, and fibrous element are miscible in water. In other words, the unit dose
article, fibrous structure, or fibrous element is capable of forming a homogeneous
solution with water at ambient conditions. "Ambient conditions" as used herein means
23°C ± 1.0°C and a relative humidity of 50% ± 2%. The water-soluble unit dose article
may contain insoluble materials, which are dispersible in aqueous wash conditions
to a suspension mean particle size that is less than about 20 microns, or less than
about 50 microns.
[0313] These fibrous water-soluble unit dose articles can be dissolved under various wash
conditions, e.g., low temperature, low water and/or short wash cycles or cycles where
consumers have been overloading the machine, especially with items having high water
absorption capacities, while providing sufficient delivery of active agents for the
intended effect on the target consumer substrates (with similar performance as today's
liquid products). Furthermore, the water-soluble unit dose articles described herein
can be produced in an economical manner by spinning fibers comprising active agents.
The water-soluble unit dose articles described herein also have improved cleaning
performance.
Method of Use.
[0314] The compositions of this invention, prepared as hereinbefore described, can be used
to form aqueous washing/treatment solutions for use in the laundering/treatment of
fabrics. Generally, an effective amount of such compositions is added to water, for
example in a conventional fabric automatic washing machine, to form such aqueous laundering
solutions. The aqueous washing solution so formed is then contacted, typically under
agitation, with the fabrics to be laundered/treated therewith. An effective amount
of the liquid detergent compositions herein added to water to form aqueous laundering
solutions can comprise amounts sufficient to form from about 500 to 7,000 ppm of composition
in aqueous washing solution, or from about 1,000 to 3,000 ppm of the laundry care
compositions herein will be provided in aqueous washing solution.
[0315] Typically, the wash liquor is formed by contacting the laundry care composition with
wash water in such an amount so that the concentration of the laundry care composition
in the wash liquor is from above 0g/l to 5g/l, or from 1g/l, and to 4.5g/l, or to
4.0g/l, or to 3.5g/l, or to 3.0g/l, or to 2.5g/l, or even to 2.0g/l, or even to 1.5g/l.
The method of laundering fabric or textile may be carried out in a top-loading or
front-loading automatic washing machine or can be used in a handwash laundry application.
In these applications, the wash liquor formed and concentration of laundry detergent
composition in the wash liquor is that of the main wash cycle. Any input of water
during any optional rinsing step(s) is not included when determining the volume of
the wash liquor.
[0316] The wash liquor may comprise 40 liters or less of water, or 30 liters or less, or
20 liters or less, or 10 liters or less, or 8 liters or less, or even 6 liters or
less of water. The wash liquor may comprise from above 0 to 15 liters, or from 2 liters,
and to 12 liters, or even to 8 liters of water. Typically, from 0.01kg to 2kg of fabric
per liter of wash liquor is dosed into said wash liquor. Typically, from 0.01kg, or
from 0.05kg, or from 0.07kg, or from 0.10kg, or from 0.15kg, or from 0.20kg, or from
0.25kg fabric per liter of wash liquor is dosed into said wash liquor. Optionally,
50g or less, or 45g or less, or 40g or less, or 35g or less, or 30g or less, or 25g
or less, or 20g or less, or even 15g or less, or even 10g or less of the composition
is contacted to water to form the wash liquor. Such compositions are typically employed
at concentrations of from about 500 ppm to about 15,000 ppm in solution. When the
wash solvent is water, the water temperature typically ranges from about 5 °C to about
90 °C and, when the situs comprises a fabric, the water to fabric ratio is typically
from about 1:1 to about 30:1. Typically the wash liquor comprising the laundry care
composition of the invention has a pH of from 3 to 11.5.
[0317] In one aspect, such method comprises the steps of optionally washing and/or rinsing
said surface or fabric, contacting said surface or fabric with any composition disclosed
in this specification then optionally washing and/or rinsing said surface or fabric
is disclosed, with an optional drying step.
[0318] Drying of such surfaces or fabrics may be accomplished by any one of the common means
employed either in domestic or industrial settings. The fabric may comprise any fabric
capable of being laundered in normal consumer or institutional use conditions, and
the invention is suitable for cellulosic substrates and in some aspects also suitable
for synthetic textiles such as polyester and nylon and for treatment of mixed fabrics
and/or fibers comprising synthetic and cellulosic fabrics and/or fibers. As examples
of synthetic fabrics are polyester, nylon, these may be present in mixtures with cellulosic
fibers, for example, polycotton fabrics. The solution typically has a pH of from 7
to 11, more usually 8 to 10.5. The compositions are typically employed at concentrations
from 500 ppm to 5,000 ppm in solution. The water temperatures typically range from
about 5°C to about 90°C. The water to fabric ratio is typically from about 1:1 to
about 30:1.
[0319] Another method includes contacting a nonwoven substrate, which is impregnated with
the detergent composition, with a soiled material. As used herein, "nonwoven substrate"
can comprise any conventionally fashioned nonwoven sheet or web having suitable basis
weight, caliper (thickness), absorbency, and strength characteristics. Non-limiting
examples of suitable commercially available nonwoven substrates include those marketed
under the trade names SONTARA
® by DuPont and POLY WEB
® by James River Corp.
Carbon Source of Raw Materials.
[0320] The raw materials for preparation of the surfactant, polymers and other ingredients
can be based on fossil carbon or renewable carbon. Renewable carbon is a carbon source
that avoid the use of fossil carbon such as natural gas, coal, petroleum. Typically,
renewable carbon is derived from the biomass, carbon capture, or chemical recycling.
[0321] Biomass is a renewable carbon source formed through photosynthesis in the presence
of sunlight, or chemosynthesis process in the absence of sunlight. In some cases,
polymers isolated from biomass can be used directly, or further derivatized to make
performance polymers. For example, the use of polysaccharide (such as starch) and
derivatized polysaccharide (such as cellulose derivatives, guar derivatives, dextran
derivatives) in fabric home care composition are known. In some cases, biomass can
be converted into basic chemicals under certain thermal, chemical, or biological conditions.
For example, bioethanol can be derived from biomass such as straw, and further convert
to biobased polyethylene glycol. Other nonlimiting examples of renewable carbon from
biomass include plants (e.g., sugar cane, beets, corn, potatoes, citrus fruit, woody
plants, lignocellulosics, hemicellulosics, cellulosic waste), animals, animal fats,
fish, bacteria, fungi, plant-based oils, and forestry products. These resources can
be naturally occurring, hybrids, or genetically engineered organisms.
[0322] Carbon capture is another renewable carbon source which use various process to capture
CO
2 or methane from industrial or natural processes, or directly from air (direct capture).
Captured methane and CO
2 maybe converted into syngas, and/or further convert to basic chemicals, including
but not limit to methanol, ethanol, fatty alcohols such as C
12/C
14 or even C
16/C
18 alcohols, other alcohols, olefins, alkanes, saturated and unsaturated organic acids,
etc. These basic chemicals can used as or further convert to monomers for making transformed
to usable chemicals by e.g. catalytic processes, such as the Fischer-Tropsch process
or by fermentation by C
1 -fixing microorganisms.
[0323] Chemical recycling is another renewable carbon source which allow plastics from waste
management industry to be recycled and converted into base chemicals and chemical
feedstocks. In some cases, waste plastics which cannot be re-used or mechanical recycled
are convert to hydrocarbons or basic petrochemicals through gasification, pyrolysis
or hydrothermal treatment processes, the hydrocarbons and basic petrochemicals can
be further convert into monomers for polymers. In some cases, waste plastics are depolymerized
into monomers to make new polymers. It is also possible that waste plastics are depolymerized
into oligomers, the oligomers can be used as building blocks to make new polymers.
The waste plastic converted by various processes to a waste plastic feedstock for
the above materials may either be used alone or in combination with traditional surfactant
feedstocks, such as kerosene, polyolefins derived from natural gas, coal, crude oil
or even biomass, or waste fat/oil-derived paraffin and olefin, to produce biodegradable
surfactants for use in detergents and other industries (thereby providing a benefit
to society).
[0324] Preferably, the surfactant, polymers and other ingredients contains renewable carbon,
the Renewable Carbon Index (RCI, a measure of sustainability by dividing the number
of carbons derived from renewable sources by the total number of carbons in an active
ingredient) of the polymer is above 10%, more preferably above 30%, more preferably
above 50%, more preferably above 60%, more preferably between 70% to 100%, and most
preferably 100%.

EXAMPLES
Method of testing polymer biodegradation
[0326] Biodegradation in wastewater was tested in triplicate using the OECD 301F manometric
respirometry method. OECD 301F is an aerobic test that measures biodegradation of
a sample by measuring the consumption of oxygen. To a measured volume of medium, 100
mg/L test substance, which is the nominal sole source of carbon is added along with
the inoculum (30 mg/L, aerated sludge taken from Mannheim wastewater treatment plant).
This is stirred in a closed flask at a constant temperature (20°C or 25°C) for 28
or 56 days, respectively. The consumption of oxygen is determined by measuring the
change in pressure in the apparatus using an OxiTop
® C (Xylem 35 Analytics Germany Sales GmbH & Co KG). Evolved carbon dioxide is absorbed
in a solution of sodium hydroxide. Nitrification inhibitors are added to the flask
to prevent usage of oxygen due to nitrification. The amount of oxygen taken up by
the microbial population during biodegradation of the test substance (corrected for
uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD (Theoretical
oxygen demand, which is measured by the elemental analysis of the compound). A positive
control Glucose/Glucosamine is run along with the test samples for each cabinet.
Method for evaluating stain removal benefit of polymers in laundry detergent.
[0327] Cleaning benefits of polymers are evaluated using automatic tergotometer. Some examples
test stains suitable for this test are:
Dust Sebum on polycotton ex CFT
Highly Discriminating Sebum on polycotton ex CFT
[0328] The stains are analysed using Image Analysis System for Laundry stain removal testing
before and after the wash.
[0329] SBL2004 test soil strips supplied by WFK Testgewebe GmbH are used to simulate consumer
soil levels (mix of body soil, food, dirt etc.). Every 1 SBL2004 strip is loaded with
8g soil. The SBL2004 test soil strips were cut into 5×5 cm squares for use in the
test.
[0330] Additional ballast (background fabric swatches) is also used to simulate a fabric
load and provide mechanical energy during the real laundry process. Ballast loads
are comprised of knitted cotton swatches at 5×5 cm size.
[0331] The desired amount of detergent is fully dissolved by mixing with 1L water (at defined
hardness) in each tergotometer pot. 60 total grams of fabrics including stains (2
internal replicates of each stain in each pot), defined amount of 5×5 cm SBL2004 and
ballast are washed and rinsed in the tergotometer pot under defined conditions. The
test is repeated for 4 times (4 external replicates).
[0332] All stains are tumbled dried between 60-65°C until dry, then stains are measured
again using Image Analysis System for Laundry stain removal testing.
[0333] Stain Removal Index (SRI) are automatically calculated from the L, a, b values using
the formula shown below. The higher the SRI, the better the stain removal.
Subscript 'b' denotes data for the stain before washing
Subscript 'a' denotes data for the stain after washing
Subscript 'c' denotes data for the unstained fabric
Method for Evaluating Flash Suds
[0334] The suds profile of a laundry detergent is a very important property to consumers.
The detergent must deliver enough suds to serve as a signal to consumers to show effective
cleaning but not too much that extra rinse effort are required to remove excess suds.
The initial bloom of suds which generated at the start of a wash cycle upon mechanical
agitation in a washing machine or in a basin when consumer is washing using their
hands, so-called "flash suds," constitutes the first suds touch point for consumer,
is a critical signal which consumer view as a sign of an effective laundry detergent.
[0335] The flash suds of comparative and inventive composition are evaluated using automatic
Tergotometer with 10 pots for laundry formulation testing.
[0336] SBL2004 test soil strips supplied by WFK Testgewebe GmbH are used to simulate consumer
soil levels (mix of body soil, food, dirt etc.). Every 1 SBL2004 strip is loaded with
8g soil. The SBL2004 test soil strips were cut into 5×5 cm squares for use in the
test.
[0337] 2500ppm of detergent is fully dissolved by mixing with 1L water at 7gpg in each tergotometer
pot with 5 pieces 5×5cm SBL2004 at 25°C for 1 minute. A one minute suds generation
cycle is then carried out, suds are allowed to stabilize for one minute after which
time a photograph is taken of each tergotometer pot at same distance and position
with flash enabled. 4 external replicates are required, and pots are rotated between
runs.
[0338] In order to determine % suds coverage of pot ImageJ imaging process software is used:
- Image Is opened in Image J
- Image is coverted to 8-bit picture
- Image is adjusted via Auto Threshold feature, under Default method, with `White objects
on black background' checked
- Wand outline tool is selected, and Tolerance changed to 22.
- Outline of inner tergotemeter pot is selected using wand.
- Result is analysed using Analyze particle feature this calculates % of white pixels
in the area selected. Areas not covered by suds will be black, areas with suds will
be white. This calculation corresponds to the suds coverage of the tergtometer pot.
Method of molecular weight measurements
[0339] The number average molecular weight (M
n), the weight average molecular weight (M
w) and the polydispersity M
w/M
n of the inventive graft polymers were determined by gel permeation chromatography
in tetrahydrofuran. The mobile phase (eluent) used was tetrahydrofuran comprising
0.035 mol/L diethanolamine. The concentration of graft polymer in tetrahydrofuran
was 2.0 mg per mL. After filtration (pore size 0.2 µm), 100 µL of this solution were
injected into the GPC system. Four different columns (heated to 60°C) were used for
separation (SDV precolumn, SDV 1000A, SDV 100000A, SDV 1000000A). The GPC system was
operated at a flow rate of 1 mL per min. A DRI Agilent 1100 was used as the detection
system. Poly(ethylene glycol) (PEG) standards (PL) having a molecular weight M
n from 106 to 1 378 000 g/mol were used for the calibration.
Synthesis of graft polymer.
[0340] The following inventive graft polymer Example 1 was synthesized according to procedure
described below.
Graft polymer Example 1
graft polymerization of vinyl acetate in a ratio of polyalkylene oxide /
VAc (60 /
40), wherein the polyalkylene oxide is triblock copolymer (PO13-EO24-PO13).
[0341] A polymerization vessel equipped with stirrer and reflux condenser was initially
charged with 600 g of triblock copolymer (PO
13-EO
24-PO
13) under nitrogen atmosphere and melted at 90°C.
[0342] Feed 1 containing 4.0 g of tert-butyl peroxy-2-ethylhexanoate, dissolved in 33.0
g of tripropylene glycol, was dosed to the stirred vessel in 6:10 h, at 90°C. 5.56%
of Feed 1 were dosed in the first 10 min and the rest was dosed with constant feed
rate for 6:00 h. 10 minutes after the start of Feed 1, Feed 2 (400 g of vinyl acetate)
was started and dosed within 6:00 h at constant feed rate and 90°C. Upon completion
of the Feeds 1 and 2, the temperature was increased to 95°C and Feed 3 consisting
of 2.55 g of tert-butyl peroxy-2-ethylhexanoate, dissolved in 21.0 g of tripropylene
glycol, were dosed within 56 min with constant flow rate at 95 °C. The mixture was
stirred for one hour at 95°C upon complete addition of the feed.
[0343] Residual amounts of monomer were removed by vacuum distillation for 1 h at 95°C and
500 mbar. The resulting graft polymer had a mean molecular weight M
w of 3 640 g/mol and a polydispersity of 1.5.
Graft polymer Example 2
graft polymerization of vinyl acetate in a ratio of polyalkylene oxide /
VAc (60 /
40), wherein the polyalkylene oxide is triblock copolymer (P06.5 EO48-PO6.5).
[0344] Instead of using triblock copolymer
(PO13-EO24-PO13) as backbone, triblock copolymer (PO
6.5-EO
48-PO
6.5) was used to make graft polymer Example 2 following similar procedure.
[0345] The resulting graft polymer had a mean molecular weight M
w of 5 190 g/mol and a polydispersity of 1.5.
[0346] Other inventive graft polymer examples 3-24 can be synthesized following similar
procedure. The structure details of graft polymer 1-24 are summarized in Table 5 below:
