Field of the Invention
[0001] The present invention relates to cleaning compositions, including laundry, dishwashing,
hard surface cleaner, oral/dental cleaning compositions, comprising a surfactant system,
an organic acid, a hydrogen peroxide source and a oxidoreductase with an α/β-hydrolase
fold and a catalytic triad consisting of the amino acid residues serine, histidine
and aspartic acid.
Background of the invention
[0002] Performance of a cleaning product, for use in washing or cleaning method, is judged
by a number of factors, including the ability to remove soils, and the ability to
prevent the redeposition of the soils, or the breakdown products of the soils on the
articles in the wash.
[0003] Coloured stains / soils are often difficult to remove effectively from a soiled item.
Highly coloured stains and soils i.e. derived from fruit and/or vegetables are particularly
challenging soils to remove. This stains and soils contain colour-bodies based on
carotenoids compounds such as α-,β and γ-carotene and lycopene and xanthophyls, on
porphyrins such as chlorophyll and on flavonoid pigments and dye components. This
latter group of natural flavonoid based dye components comprises the highly coloured
anthocyanins dyes and pigments based on pelargonidin, cyanidin, delphidin and their
methyl esters and the antoxanthins. These compounds are the origin of most of the
orange, red, violet and blue colours occurring in fruits and are abundant in all berries,
cherry, red and black currents, grapefruits, passion fruit, oranges, lemons, apples,
pears, pommegranate, red cabbage, red beets and also flowers. Derivatives of cyanidin
are present in up to 80% of the pigmented leaves, in up to 70% of fruits and in up
to 50% of flowers. Specific examples of such soils would include tea, coffee, spices
such as curry and paprika, orange, tomato, banana, tea, mango, broccoli, carrot, beetroot,
spinach soils and grass. Ball pens' ink are also known to be highly difficult coloured
stains to be removed.
[0004] In addition, the complex nature of everyday "body" soils typically found on pillow
cases, T-shirts, collars and socks, provides a continuous thorough cleaning challenge
for cleaning products. These soils are difficult to remove completely and often residues
build up on fabric leading to dinginess and yellowing. Everyday body soils are also
found on sanitary and kitchen surfaces such as bathtubs, toilet bowl and dishware.
[0005] The items can be fabrics, hard surfaces, dishware such as plasticware, glassware
or chinaware, teeth and mouth.
[0006] Traditionally, high levels of bleaching agents, optionally with bleach precursors
and/or bleach enhancers, are incorporated in cleaning compositions. Bleaching agents
are compounds which are precursors of hydrogen peroxide which is formed in the course
of the washing procedure. Perborates and percarbonates are the most important examples
of such hydrogen peroxide precursors.
[0007] In view of the above, there exits clearly a continuous need to provide cleaning compositions
which have an excellent detergency performance. Accordingly it is an object of the
present invention to provide a cleaning composition which provides effective and efficient
cleaning of coloured and/or everyday body stains and/or soils. It is a further object
to provide a cleaning composition which provides fabric realistic items cleaning and
whitening while avoiding colour fading.
[0008] The above objective has been met by formulating cleaning compositions comprising
a surfactant system, an organic acid, a hydrogen peroxide source and an oxidoreductase
with an α/β-hydrolase fold and a catalytic triad consisting of the amino acid residues
serine, histidine and aspartic acid, usually referred to as "non-heme haloperoxidase".
[0009] In a preferred embodiment, the present invention relates to a laundry composition
comprising a surfactant system, an organic acid, a hydrogen peroxide source and a
non-heme haloperoxidase further providing fabric realistic items cleaning and whitening.
In a second embodiment, the present invention relates to dishwashing or household
cleaning compositions comprising a surfactant system, an organic acid, a hydrogen
peroxide source and a non-heme haloperoxidase and in a third embodiment, the present
invention relates to oral/dental care compositions comprising a surfactant system,
an organic acid, a hydrogen peroxide source and a non-heme haloperoxidase.
[0010] It has been surprisingly found that a non-heme haloperoxidase based enzymatic bleach
system delivers in a detergent composition, bleach-like benefits in an unexpected
broad range of performance areas such as dingy cleaning, whiteness maintenance and
stain removal. It has also been found that the cleaning compositions of the present
invention provide sanitisation of the treated surfaces. It has been further found
the performance of the cleaning compositions of the present invention is enhanced
by the addition of another enzymatic bleach system, a conventional activated bleach
system, a metallo catalyst based bleach system and/or another detergent enzyme.
[0011] WO95/27046 discloses antimicrobial compositions comprising a vanadium haloperoxidase,
a source of halide and hydrogen peroxide or a source thereof, wherein the vanadium
haloperoxidase is a chloroperoxidase obtainable from
Curvularia inaequalis. These enzymatic antimicrobial compositions generally comprise from 0.01 to 50% by
weight of one or more surfactants.
[0012] WO96/06909 describes enzymatic, active oxygen-releasing mixtures which might be used
as oxidising agents for preparing chemical compounds and in bleaching, cleaning and
disinfecting agents. Said mixtures contain oxidoreductase with an α/β-hydrolase fold
and a catalytic triad consisting of the serine, histidine and aspartic acid amino
acids; a hydrogen peroxide source and an aqueous solution of an organic acid or its
salt. These organic acids or salts are converted into organic peracids at a pH value
from 3.5 to 6.0 and temperature from 15°C to 80°C.
[0013] However, the use of an enzymatic bleach system comprising an organic acid, a hydrogen
peroxide source and a oxidoreductase with an α/β-hydrolase fold and a catalytic triad
consisting of the amino acid residues serine, histidine and aspartic acid, in a surfactant-containing
cleaning composition, has never been previously recognised.
Summary of the invention
[0014] The present invention relates to cleaning compositions, including laundry, dishwashing,
hard surface cleaner, oral/dental cleaning compositions having a pH of 7-12, comprising
a surfactant system, an organic acid as specified in Claim 1, a hydrogen peroxide
source and an oxidoreductase with an α/β-hydrolase fold and a catalytic triad consisting
of the amino acid residues serine, histidine and aspartic acid. The cleaning compositions
of the present invention provide effective and efficient cleaning of coloured and/or
everyday body stains and/or soils and sanitisation of the treated surfaces.
[0015] In a preferred embodiment, the present invention relates to laundry detergent compositions
providing fabric realistic items cleaning and whitening while avoiding colour fading.
Detailed description of the invention
Non-heme haloperoxidase enzyme :
[0016] An essential component of the cleaning compositions of the invention is an oxidoreductase
with an α/β-hydrolase fold and a catalytic triad consisting of the amino acid residues
serine, histidine and aspartic acid, usually referred to as a non-heme haloperoxidase.
[0017] It has been found that the cleaning compositions of the present invention provide
effective and efficient cleaning of coloured and everyday body stains and/or soils
and in particular provide fabric realistic items cleaning and whitening while avoiding
colour fading when formulated as a laundry detergent composition.
[0018] In addition, the cleaning compositions of the present invention provide sanitisation
of the treated surfaces.
Sanitisation includes all positive effects obtained by the inhibition or reduction
of microbial activity on fabrics and other surfaces, such as the prevention of malodour
development and bacterial/fungal growth. For example, it provides prevention of malodour
development on stored and weared fabrics, on stored dishware, especially plastic kitchen
gear and in toilets. In particular, the composition of the invention will inhibit
or at least reduce the bacterial and/or fungal development on moist fabric waiting
for further laundry processing and thereby preventing the formation of malodour. In
addition, bacterial and/or fungal growth on hard surfaces such as tiles and their
silicone joints, sanitary installations, will be prevented.
The sanitisation potential of the cleaning compositions of the present invention
can be enhanced by the addition of chemical sanitisers such as Triclosan and/or hexemidine.
Parfums Cosmétiques Actualites No 125, Nov, 1995, 51-4 describes suitable chemical
sanitisers.
The sanitisation benefits of the cleaning compositions of the present invention
can be evaluated by the Minimum Inhibitory Concentration (MIC) as described in Tuber.
Lung. Dis. 1994 Aug; 75(4):286-90; J. Clin. Microbiol. 1994 May; 32(5):1261-7 and
J. Clin. Microbiol. 1992 Oct; 30(10):2692-7.
[0019] Without wishing to be bound by theory, it is believed that the peroxy acids produced
in situ by the non-heme haloperoxidase, have excellent bleaching performance on a
wide range of bleachable substrates including everyday body (dingy soils), coloured
stains/soils removal and whitening. Indeed, it is believed that the low level of the
organic per-acid formed by the activity of the non-heme haloperoxidase on the organic
acid brings about the oxidation of the natural and synthetic dyes and of soil components
in solution and on surfaces. The coloured plant and fruit stains also contain highly
colored colour-bodies associated with cell wall constituents. All these natural dyestuffs
are based on highly conjugated poly-aromatic compounds. The colour of these materials
fades upon oxidation by the peracid due to disruption of the colour-forming conjugated
system in the compound.
[0020] Without wishing to be bound by theory, it is believed that the body soil removal
in the cleaning compositions of the present invnetion is achieved by the oxidation
of the body soils componenets by the low level of organic peracid formed by the non-heme
haloperoxidase. This oxidation results in the hydrophilic substitution of the body
soil component and/or the fragmentation of the body soil component. These mechanisms
lead to an enhanced removal of the body soil components from the articles in the wash.
[0021] Haloperoxidases are a widely distributed family of enzymes catalysing the formation
of carbon-halogen bonds in presence of hydrogen peroxide, halides ions and a suitable
organic substrate. According to molecular and catalytic properties, these enzymes
can be classified in two subsets : the heme containing and non-heme containing haloperoxidases.
The heme containing enzymes usuallly contain a protoporphyrin IX as prosthetic group
and demonstrate catalase and peroxidase enzymatic activities. The non-heme containing
enzymes can be further divided into two classes : eukaryotic haloperoxidases containing
vanadium and bacterial non-heme haloperoxidase which require neither metal ions nor
any other cofactors ("The non-haem chloroperoxidase from
Pseudomonas fluorescens and its relationship to pyrrolnitrin biosynthesis" by S. Kirner at al. Microbiology
(1996), 142, 2129-2135).
[0022] Halogenating enzymes have been extensively studied : "Bacterial haloperoxidase and
their role in secondary metabolism" by K.H. van Pée, Biotech. Adv. Vol 8, pp 185-205,
1990 wherein non-heme haloperoxidase from several bacterias are compared in table
2 page 198 - "Biosynthesis of halogenated metabolites by bacteria" by K.H. van Pée,
Annu. Rev. Microbiol. 1996, 50:375-99 describing on page 389 vanadium-containing non-heme
haloperoxidases and bacterial non-heme haloperoxidases on pages 389-392.
[0023] Suitable for the purpose of the present invention are enzymes which contain a catalytical
triad consisting of aspartate, histidine and serine amino acids, involved in the halogenating
enzymatic activity. The first step of the halogenation catalysed by the bacterial
non-heme haloperoxidase is the formation of an acetate ester at the serine residue
of the catalytical triad. This ester is not hydrolysed by water but by hydrogen peroxide,
resulting in the production of a peracetic acid. As a strong oxidation agent, the
peracid acids are capable of oxidising unspecifically bromide, chloride and aromatic
amino to nitro groups. The non-heme haloperoxidases lack substrate specificity.
[0024] Non-heme bromoperoxidase enzymes are producible from Corallina marina algae (JP63
196 295 and JP61 242 577). Suitable non-heme haloperoxidases for the purpose of the
present invention can be obtained as listed below:
1. non-heme Chloro-and Bromo peroxidases from Pseudomonas species and Streptomyces
species and Serratia species described in WO 9606909 of Degussa pp 7-9:
1.1. non-heme Chloro peroxidase from Serratia marcescens as described in Microbiol.Lett.Vol.129,
p 255-260 (1995).
1.2. non-heme bromo peroxidase from Streptomyces aureofaciens ATCC 10762 in J.Gen.Microbiol.
137, p2539-2546 (1992).
1.3. non-heme chloro peroxidase from Pseudomonas fluorescens as described in Microbiology(1996)
,142,2129-2135 by S.Kimer et all.
2. non-heme Bromo peroxidase from Corallina marine algae (e.g C.officinalis, C. pilulifera,
C. squamata, Serraticardia maxima, Calliarthron yessoense) as described in J63196295
and J61242577 both of Amano Pharm KK.
Preferred non-heme haloperoxidase for use in the present invention are the enzymes
obtained such as described in WO96/06909, more preferred enzyme is the non-heme chloroperoxidase
obtained from Serratia marcescens.
[0025] The non-heme haloperoxidase is incorporated into the cleaning compositions of the
present invention preferably at a level of from 0.0001 % to 2%, more preferably from
0.001% to 1.0%, most preferred from 0.005% to 0.1% pure enzyme by weight of the composition.
[0026] Preferred non-heme haloperoxidases for specific applications are alkaline , i.e.
enzymes having an enzymatic activity of at least 10%. preferably at least 25%, more
preferably at least 40% of its maximum activity at a pH ranging from 7 to 12. More
preferred non-heme haloperoxidases are enzymes having their maximum activity at a
pH ranging from 7 to 12.
[0027] Enzymes homologue to the non-heme haloperoxidase enzymes of the present invention
are also contemplated. The term "homologue" is intended to present invention are also
contemplated. The term "homologue" is intended to indicate a polypeptide encode by
DNA which hybridises to the same probe as the DNA coding for the non-heme haloperoxidase
enzyme with this amino acid sequence under certain specific conditions (such as presoaking
in 5xSSC and prehybridising for 1 h at ~40°C in a solution of 20% formamide, 5xDenhardt's
solution, 50 mM sodium phosphate, pH 6.8, and 50 µg of denaturated sonicated calf
thymus DNA, followed by hybridisation in the same solution supplemented with 100 µM
ATP for 18 h at ~40°C). The term is intended to include derivatives of the non-heme
haloperoxidase enzyme sequence obtained by addition of one or more amino acid residues
to either or both the C- and N-terminal of the native sequence, substitution of one
or more amino acid residues at one or more sites in the native sequence, deletion
of one or more amino acid residues at either or both ends of the native amino acid
sequence or at one or more sites within the native sequence, or insertion of one or
more amino acid residues at one or more sites of the native sequence.
[0028] The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal,
bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic
(psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic,
halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Nowadays,
it is common practice to modify wild-type enzymes via protein / genetic engineering
techniques in order to optimise their performance efficiency in the cleaning compositions
of the invention. For example, the variants may be designed such that the compatibility
of the enzyme to commonly encountered ingredients of such compositions is increased.
Alternatively, the variant may be designed such that the optimal pH, bleach or chelant
stability, catalytic activity and the like, of the enzyme variant is tailored to suit
the particular cleaning application.
In particular, attention should be focused on amino acids sensitive to oxidation
in the case of bleach stability and on surface charges for the surfactant compatibility.
The isoelectric point of such enzymes may be modified by the substitution of some
charged amino acids, e.g. an increase in isoelectric point may help to improve compatibility
with anionic surfactants. The stability of the enzymes may be further enhanced by
the creation of e.g. additional salt bridges and enforcing calcium binding sites to
increase chelant stability.
The organic acid :
[0029] A second essential element of the cleaning compositions of the present invention
is an organic acid. The organic acid is characterised by a pKa value at 20°C between
2 and 10, preferably between 3 and 9 and more preferably between 3,5 and 8.
Suitable acids are listed in CRC Handbook for Chemistry and Physics, D. R. Lide,
71
st Edition, CRC press, section 8, pp35-36. Suitable organic acids are acetic, propionic,
butyric, hexanoic, octanoic, decanoic, malic, oxalic, benzoic, citric acids and/or
mixtures thereof and/or salts thereof. Also suitable are lactic acids, fruitacids,
benzoic acids, phtalic acids and/or mixtures thereof and/or salts thereof.
Preferred organic acids are monocarboxylic acids of the formula RnH(n+1)COOH wherein
n = 1-9 such as actic acid, propionic acid, nonanoic acid, and /or their corresponding
sodium salts.
The organic acids are generally incorporated into the cleaning compositions of
the present invention at a level of from 0.1% to 50%, preferably from 0.5% to 40%,
more preferably from 1% to 20% by weight of total composition.
The hydrogen peroxide source :
[0030] A third essential element of the cleaning compositions of the present invention is
a source of hydrogen peroxide. Suitable hydrogen peroxide source are any compound
or system that can release hydrogen peroxide in the wash solution. Examples are percarbonate,
perborate or enzymatic systems generating in situ hydrogen peroxide, such as oxidases.
[0031] Suitable sources of hydrogen peroxide for the present invention include hydrogen
peroxide releasing agents such as hydrogen peroxide, perborates, e.g. perborate monohydrate,
perborate tetrahydrate, persulfates, percarbonates, peroxydisulfates, perphosphates,
peroxyhydrates and urea hydrogen peroxide. Preferred bleaches are percarbonates and
perborates.
[0032] It may be also desirable to utilize an enzymatic process for hydrogen peroxide formation.
Thus, the process according to the invention may additionally comprise adding an enzymatic
system (i.e. an enzyme and a substrate therefore) which is capable of generating hydrogen
peroxide during the washing process. One such category of hydrogen peroxide generating
systems comprises enzymes which are able to convert molecular oxygen and an organic
or inorganic substrate into hydrogen peroxide and the oxidized substrate respectively.
These enzymes produce only low levels of hydrogen peroxide, but they may be employed
to great advantage in the process of the invention as the presence of oxidase ensures
an efficient utilization of the hydrogen peroxide produced. Preferred hydrogen peroxide
generating enzymes are those which act on cheap and readily available substrates which
may conveniently be included into cleaning compositions. For example, one may use
an amine oxidase and an amine, an amino acid oxidase and an amino acid, lactate oxidase
and lactate, cholesterol oxidase and cholesterol, uric acid oxidase and uric acid,
or xanthine oxidase with xanthine. Other suitable oxidases are urate oxidase, galactose
oxidase, alcohol oxidase and amyloglucosidase.
[0033] The preferred enzymatic systems are alcohol and aldehyde oxidases. The more preferred
systems for granular detergent application would have solid alcohols, e.g. glucose
whose oxidation is catalysed by glucose oxidase to glucoronic acid with the formation
of hydrogen peroxide. Preferred is the combination of glucose oxidase and glucose.
The amount of glucosed oxidase will depend on its specific activity and the activity
of residual catalase that may be present, but by way of an example it can be stated
generally that the detergent composition according to the invention will contain from
10 to 1000, preferably from 20 to 500 units of glucose oxidase per g or ml of the
detergent composition, a unit of enzyme activity being defined as the quantity required
to convert 1 µmol substrate per minute under standard conditions.
The more preferred systems for liquid detergent application would involve liquid alcohols
which could also act as, for example, solvents. An example is ethanol/ethanol oxidase.
Such enzymatic systems are disclosed in EP Patent Application EP 537 381 filed October
9, 1991.
[0034] The level of hydrogen peroxide in the wash solution is critical for the stability
of the non-heme haloperoxidase. Therefore, controlled release of the hydrogen peroxide
into the wash solution might be used in the non-heme haloperoxidase enzymatic bleach
system.
[0035] The hydrogen peroxide is generally present in the wash solution at a level of from
0.0001 - 10 mmoles, preferably 0.0001 - 2 mmoles, more preferably 0.0001 - 0.3 mmoles;
maintained preferably with a controlled releasing system.
The hydrogen peroxide can be generated by a perborate, percarbonate system, an
enzymatic system for generating hydrogen peroxide at a level of 0.1 - 0.2 mmole.
[0036] A release agent is an agent which releases the incorporated hydrogen peroxide source
into the wash environment in a controlled manner.
[0037] For granular and powder cleaning products, the hydrogen peroxide source can be contained
in a granulate. Said granulate may suitably further contain various granulation aids,
binders, fillers, plasticizers, lubricants, cores and the like. Examples thereof include
cellulose (e.g. cellulose in fibre or microcrystalline form), dextrins (e.g. yellow
dextrin), polyvinylpyrrolidone, polyvinylalcohol, cellulose derivatives (such as CMC,
MC, HPC or HPMC), gelatin, starch sugar, salts (e.g. sodium sulfate, sodium chloride,
calcium sulfate or calcium carbonate), titanium dioxide, talc and clays (e.g. kaolin
or bentonite). Other materials of relevance for incorporation in the granulates of
the type in question are described, for example, in EP 0 304 331 B1, and will be well
known to persons skilled in the art.
The release agent may be, for example, a coating. Said coating protects said granulates
(co-granulates) in the wash environment for a certain period of time. The coating
will normally be applied to said granulates (co-granulates) in an amount in the range
of 1% to 50% by weight (calculated on the basis of the weight of the uncoated, dry
granulate), preferably in the range of 5 % to 40 % by weight. The amount of coating
to be applied to said granulates will depend to a considerable extent on the nature
and composition of the desired coating, and to the kind of protection said coating
should offer to said granulates. For example, the thickness of said coating or a multi-layered
coating applied onto any of the above granulates may determine the period in which
the content of said granulates is released. A possible multi-layered coating may be
a coating in which, for example, a fast release coating is coated over a slow release
coating.
Suitable release coatings are coatings which give rise to release of the contents
of the source of peroxide-granulates according to the present invention under the
conditions prevailing during the use thereof. Thus, for example, when a preparation
of the invention is to be introduced into a washing liquor containing a washing detergent
(normally comprising, e.g. one or more types of surfactants), the coating should be
one which ensures the release of the contents of said granulates from the release
agent when it is introduced into the washing medium.
Preferred release coating are coatings which are substantially insoluble in water.
Release coatings which are appropriate in washing media may suitably comprise substances
selected from the following: tallow; hydrogenated tallow; partially hydrolyzed tallow;
fatty acids and fatty alcohols of natural and synthetic origin; long-chain fatty acid
mono-, di- and triesters of glycerol (e.g. glycerol monostearate); ethoxylated fatty
alcohols; latexes; hydrocarbons of melting point in the range of 50-80°C; and waxes.
Melt-coating agents are a preferred class of fast or slow release coating agents which
can be used without dilution with water. Reference may be made to Controlled Release
Systems : Fabrication Technology, Vol. I, CRC Press, 1988, for further information
on slow release coating.
Coatings may suitably further comprise substances such as clays (e.g. kaolin),
titanium dioxide, pigments, salts (such as calcium carbonate) and the like. The person
skilled in the art will be aware of further coating constituents of relevance in the
present invention.
[0038] In the liquid cleaning compositions of the present invention, the hydrogen peroxide
source can be incorporated as a dispersion of particles further containing a release
agent. The hydrogen peroxide source can be present in a liquid or solid form. suitable
particles consist of a porous hydrophobic material (e.g. silica with an average pore
diametre of 5.10
-8 m (500 Angstrom) or higher) such as described in EP 583 512 of Surutzidiz A. et al.
The release agent might be a coating which protects said particles in the wash
cycle for a certain period of time. The coating is preferably a hydrophobic material
such as hydrophobic liquid polymer. Said polymer can be an organo polysiloxane oil,
alternatively a high molecula weight hydrocarbon or water-insoluble but water-permeable
polymeric material such as CMC, PVA or PVP. The polymer properties are selected to
achieve suitable release profile of the source of peroxide in the wash solution.
The Surfactant system :
[0039] The cleaning compositions according to the present invention comprise a surfactant
system wherein the surfactant can be selected from nonionic and/or anionic and/or
cationic and/or ampholytic and/or zwitterionic and/or semi-polar surfactants.
[0040] The surfactant is typically present at a level of from 0.1% to 60% by weight. More
preferred levels of incorporation are 1% to 35% by weight, most preferably from 1%
to 30% by weight of cleaning compositions in accord with the invention.
[0041] The surfactant is preferably formulated to be compatible with enzyme components present
in the composition. In liquid or gel compositions the surfactant is most preferably
formulated such that it promotes, or at least does not degrade, the stability of any
enzyme in these compositions.
[0042] Preferred surfactant systems to be used according to the present invention comprise
as a surfactant one or more of the nonionic and/or anionic surfactants described herein.
[0043] Polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols
are suitable for. use as the nonionic surfactant of the surfactant systems of the
present invention, with the polyethylene oxide condensates being preferred. These
compounds include the condensation products of alkyl phenols having an alkyl group
containing from 6 to 14 carbon atoms, preferably from 8 to 14 carbon atoms, in either
a straight-chain or branched-chain configuration with the alkylene oxide. In a preferred
embodiment, the ethylene oxide is present in an amount equal to from 2 to 25 moles,
more preferably from 3 to 15 moles, of ethylene oxide per mole of alkyl phenol. Commercially
available nonionic surfactants of this type include Igepal
TM CO-630, marketed by the GAF Corporation; and Triton
TM X-45, X-114, X-100 and X-102, all marketed by the Rohm & Haas Company. These surfactants
are commonly referred to as alkylphenol alkoxylates (e.g., alkyl phenol ethoxylates).
[0044] The condensation products of primary and secondary aliphatic alcohols with from 1
to 25 moles of ethylene oxide are suitable for use as the nonionic surfactant of the
nonionic surfactant systems of the present invention. The alkyl chain of the aliphatic
alcohol can either be straight or branched, primary or secondary, and generally contains
from 8 to 22 carbon atoms. Preferred are the condensation products of alcohols having
an alkyl group containing from 8 to 20 carbon atoms, more preferably from 10 to 18
carbon atoms, with from 2 to 10 moles of ethylene oxide per mole of alcohol. 2 to
7 moles of ethylene oxide and most preferably from 2 to 5 moles of ethylene oxide
per mole of alcohol are present in said condensation products. Examples of commercially
available nonionic surfactants of this type include Tergitol
TM 15-S-9 (the condensation product of C
11-C
15 linear alcohol with 9 moles ethylene oxide), tergitol
TM 24-L-6 NMW (the condensation product of C

of HLB in these products is from 8-11 and most preferred from 8-10.
[0045] Also useful as the nonionic surfactant of the surfactant systems of the present invention
are the alkylpolysaccharides disclosed in U.S. Patent 4,565,647, Lienado, issued January
21, 1986, having a hydrophobic group containing from 6 to 30 carbon atoms, preferably
from 10 to 16 carbon atoms and a polysaccharide, e.g. a polyglycoside, hydrophilic
group containing from 1.3 to 10, preferably from 1.3 to 3, most preferably from 1.3
to 2.7 saccharide units. Any reducing saccharide containing 5 or 6 carbon atoms can
be used, e.g., glucose, galactose and galactosyl moieties can be substituted for the
glucosyl moieties (optionally the hydrophobic group is attached at the 2-, 3-, 4-,
etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside).
The intersaccharide bonds can be, e.g., between the one position of the additional
saccharide units and the 2-, 3-, 4-, and/or 6- positions on the preceding saccharide
units. The preferred alkylpolyglycosides have the formula
R
2O(C
nH
2nO)
t(glycosyl)
x
wherein R
2 is selected from the group consisting of alkyl, alkylphenyl, hydroxyalkyl, hydroxyalkylphenyl,
and mixtures thereof in which the alkyl groups contain from 10 to 18, preferably from
12 to 14, carbon atoms; n is 2 or 3, preferably 2; t is from 0 to 10, preferably 0;
and x is from 1.3 to 10, preferably from 1.3 to 3, most preferably from 1.3 to 2.7.
The glycosyl is preferably derived from glucose. To prepare these compounds, the alcohol
or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source
of glucose, to form the glucoside (attachment at the 1-position). The additional glycosyl

to this hydrophobic portion tends to increase the water solubility of the molecule
as a whole, and the liquid character of the product is retained up to the point where
the polyoxyethylene content is 50% of the total weight of the condensation product,
which corresponds to condensation with up to 40 moles of ethylene oxide. Examples

propylene oxide, and generally has a molecular weight of from 2500 to 3000. This hydrophobic
moiety is condensed with ethylene oxide to the extent that the condensation product
contains from 40% to 80% by weight of polyoxyethylene and has a molecular weight of
from 5,000 to 11,000. Examples of this type of nonionic surfactant include certain

Detergent components
[0080] The cleaning compositions of the invention may also contain additional detergent
components. The precise nature of these additional components, and levels of incorporation
thereof will depend on the physical form of the composition, and the nature of the
cleaning operation for which it is to be used.
[0081] In a preferred embodiment, the present invention relates to a laundry and/or fabric
care composition comprising a surfactant system and a non-heme haloperoxidase (Examples
1-18). In a second embodiment, the present invention relates to dishwashing or household
cleaning compositions - including sanitisation frormulations (Examples 18-28) and
in a third embodiment, the present invention relates to oral/dental care compositions
(Examples 29-30).
[0082] The cleaning compositions according to the invention can be liquid, paste, gels,
bars, tablets, spray, foam, powder or granular forms. Granular compositions can also
be in "compact" form, the liquid compositions can also be in a "concentrated" form.
[0083] The compositions of the invention may for example, be formulated as hand and machine
dishwashing compositions, hand and machine laundry detergent compositions including
laundry additive compositions and compositions suitable for use in the soaking and/or
pretreatment of stained fabrics, rinse added fabric softener compositions, and compositions
for use in general household hard surface cleaning operations. Compositions containing
such non-heme haloperoxidase can also be formulated as oral /dental care compositions.

of the invention preferably contain a surfactant and preferably other detergent compounds
selected from organic polymeric compounds, suds enhancing agents, group II metal ions,
solvents, hydrotropes and additional enzymes.

Such additive products are intended to supplement or boost the performance of conventional
detergent compositions.
[0087] If needed the density of the laundry detergent compositions herein ranges from 400
to 1200 g/litre, preferably 600 to 950 g/litre of composition measured at 20°C.
[0088] The "compact" form of the compositions herein is best reflected by density and, in
terms of composition, by the amount of inorganic filler salt; inorganic filler salts
are conventional ingredients of detergent compositions in powder form; in conventional
detergent compositions, the filler salts are present in substantial amounts, typically
17-35% by weight of the total composition.
In the compact compositions, the filler salt is present in amounts not exceeding
15% of the total composition, preferably not exceeding 10%, most preferably not exceeding
5% by weight of the composition.
The inorganic filler salts, such as meant in the present compositions are selected
from the alkali and alkaline-earth-metal salts of sulphates and chlorides.

[0089] Liquid detergent compositions according to the present invention can also be in a
"concentrated form", in such case, the liquid detergent compositions according the
present invention will contain a lower amount of water, compared to conventional liquid
detergents.
Typically the water content of the concentrated liquid detergent is preferably
less than 40%, more preferably less than 30%, most preferably less than 20% by weight
of the detergent composition.
Conventional detergent enzymes
[0090] The cleaning compositions can in addition to the non-heme haloperoxidase enzyme further

WO96/23873 (Novo Nordisk). Other amylolytic enzymes with improved properties with
respect to the activity level and the combination of thermostability and a higher
activity level are described in WO95/35382.
The amylolytic enzymes are incorporated in the detergent compositions of the present
invention a level of from 0.0001% to 2%, preferably from 0.00018% to 0.06%, more preferably
from 0.00024% to 0.048% pure enzyme by weight of the composition.
[0097] The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal,
bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic
(psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic,
halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Also
included by definition, are mutants of native enzymes. Mutants can be obtained e.g.
by protein and/or genetic engineering, chemical and/or physical modifications of native
enzymes. Common practice as well is the expression of the enzyme via host organisms
in which the genetic material responsible for the production of the enzyme has been
cloned.
[0098] Said enzymes are normally incorporated in the detergent composition at levels from
0.0001% to 2% of active enzyme by weight of the detergent composition. The enzymes
can be added as separate single ingredients (prills, granulates, stabilized liquids,
etc... containing one enzyme ) or as mixtures of two or more enzymes ( e.g. cogranulates).
[0099] Other suitable detergent ingredients that can be added are enzyme oxidation scavengers
which are described in Copending European Patent application EP 553 607 filed on January
31, 1992. Examples of such enzyme oxidation scavengers are ethoxylated tetraethylene
polyamines.

Bleaching agent
[0101] Preferred additional optional detergent ingredients that can be included in the cleaning
compositions of the present invention include conventional activated-, other enzymatic-
and/or metallo catalyst-bleach systems. It has been found that the combination of
the non-heme haloperoxidase with another bleach system provides improved cleaning
of coloured and/or everyday body stains and/or soils and when formulated as laundry
composition, improved fabric realistic items cleaning and whitening.
[0102] The bleaching agent component for use herein can be any of the bleaching agents useful
for cleaning compositions including oxygen bleaches as well as others known in the
art. The bleaching agent suitable for the present invention can be an activated or
non-activated bleaching agent.
[0103] Bleaching agents are such as hydrogen peroxide, PB1, PB4 and percarbonate with a
particle size of 400-800 microns. These bleaching agent components can include one
or more oxygen bleaching agents and, depending upon the bleaching agent chosen, one
or more bleach activators. When present oxygen bleaching compounds will typically
be present at levels of from 1% to 25%.
[0104] The hydrogen peroxide releasing agents can be used in combination with bleach activators
such as tetraacetylethylenediamine (TAED), nonanoyloxybenzene-sulfonate (NOBS, described
in US 4,412,934), 3,5,-trimethylhexanoloxybenzenesulfonate (ISONOBS, described in
EP 120,591) or pentaacetylglucose (PAG)or Phenolsulfonate ester of N-nonanoyl-6-aminocaproic
acid (NACA-OBS, described in WO94/28106) which are perhydrolyzed to form a peracid
as the active bleaching species, leading to improved bleaching effect. Also suitable
activators are acylated citrate esters such as disclosed in Copending European Patent
Application EP 624 154 and unsymetrical acyclic imide bleach activator of the following
formula as disclosed in the Procter & Gamble co-pending patent application WO 98/04664:

wherein R
1 is a C
7-C
13 linear or branched chain saturated or unsaturated alkyl group, R
2 is a C
1-C
8, linear or branched chain saturated or unsaturated alkyl group and R
3 is a C
1-C
4 linear or branched chain saturated or unsaturated alkyl group.
[0105] One category of oxygen bleaching agent that can be used encompasses percarboxylic
acid bleaching agents and salts thereof. Suitable examples of this class of agents
include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of meta-chloro
perbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid and diperoxydodecanedioic acid.
Such bleaching agents are disclosed in U.S. Patent 4,483,781, U.S. Patent Application
740,446, European Patent Application 0,133,354 and U.S. Patent 4,412,934. Highly preferred
bleaching agents also include 6-nonylamino-6-oxoperoxycaproic acid as described in
U.S. Patent 4,634,551.
Another category of bleaching agents that can be used encompasses the halogen bleaching
agents. Examples of hypohalite bleaching agents, for example, include trichloro isocyanuric
acid and the sodium and potassium dichloroisocyanurates and N-chloro and N-bromo alkane
sulphonamides. Such materials are normally added at 0.5-10% by weight of the finished
product, preferably 1-5% by weight.
[0106] Useful bleaching agents, including peroxyacids and bleaching systems comprising bleach
activators and peroxygen bleaching compounds for use in detergent compositions according
to the invention are described in our co-pending applications WO95/10592, WO97/00937,
WO95/27772, WO95/27773, WO95/27774 and WO95/27775.
[0107] The hydrogen peroxide may also be present by adding an enzymatic system (i.e. an
enzyme and a substrate therefore) which is capable of generating hydrogen peroxide
at the beginning or during the washing and/or rinsing process. Such enzymatic systems
are disclosed in EP Patent Application EP 537 381 filed October 9, 1991.
Peroxidase enzymes are used in combination with hydrogen peroxide, oxygen sources,
e.g. percarbonate, perborate, persulfate, hydrogen peroxide, etc. and a bleach enhancer.
They are used for "solution bleaching", i.e. to prevent transfer of dyes or pigments
removed from substrates during wash operations to other substrates In the wash solution.
Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase,
ligninase and haloperoxidase such as chloro- and bromo-peroxidase. Peroxidase-containing
detergent compositions are disclosed, for example, in PCT International Application
WO 89/099813, WO89/09813 and in European Patent application EP 540 784 filed on November
6, 1991. Also suitable is the laccase enzyme.
Enhancers are generally comprised at a level of from 0.1% to 5% by weight of total
composition. Preferred enhancers are substitued phenthiazine and phenoxasine 10-Phenothiazinepropionicacid
(PPT), 10-ethylphenothiazine-4-carboxylic acid (EPC), 10-phenoxazinepropionic acid
(POP) and 10-methylphenoxazine (described in WO 94/12621) and substitued syringates
(C3-C5 substitued alkyl syringates) and phenols. Sodium percarbonate or perborate
are preferred sources of hydrogen peroxide.
Said peroxidases are normally incorporated in the detergent composition at levels
from 0.0001% to 2% of active enzyme by weight of the detergent composition.
[0108] Metal-containing catalysts for use in bleach compositions, include cobalt-containing
catalysts such as Pentaamine acetate cobalt(III) salts and manganese-containing catalysts
such as those described in EPA 549 271; EPA 549 272; EPA 458 397; US 5,246,621; EPA
458 398; EPA 458 397; US 5,194,416 and US 5,114,611. Bleaching composition comprising
a peroxy compound, a manganese-containing bleach catalyst and a chelating agent is
described in the patent application EP 718 398.
Preferred metal-contaning catalyst for the purpose of the present invention is
a transition metal complex of a macropolycyclic rigid ligand. The phrase "macropolycyclic
rigid ligand" is sometimes abbreviated as "MRL" in discussion below. The amount used
is a catalytically effective amount, suitably about 1 ppb or more, for example up
to about 99.9%, more typically about 0.001 ppm or more, preferably from about 0.05
ppm to about 500 ppm (wherein "ppb" denotes parts per billion by weight and "ppm"
denotes parts per million by weight).
Suitable transition metals e.g., Mn are illustrated hereinafter. "Macropolycyclic"
means a MRL is both a macrocycle and is polycyclic. "Polycyclic" means at least bicyclic.
The term "rigid" as used herein herein includes "having a superstructure" and "cross-bridged".
"Rigid" has been defined as the constrained converse of flexibility: see D.H. Busch.,
Chemical Reviews., (1993),
93, 847-860, incorporated by reference. More particularly, "rigid" as used herein means
that the MRL must be determinably more rigid than a macrocycle ("parent macrocycle")
which is otherwise identical (having the same ring size and type and number of atoms
in the main ring) but lacking a superstructure (especially linking moieties or, preferably
cross-bridging moieties) found in the MRL's. In determining the comparative rigidity
of macrocycles with and without superstructures, the practitioner will use the free
form (not the metal-bound form) of the macrocycles. Rigidity is well-known to be useful
in comparing macrocycles; suitable tools for determining, measuring or comparing rigidity
include computational methods (see, for example, Zimmer,
Chemical Reviews, (1995), 95(38), 2629-2648 or Hancock et al.,
Inorganica Chimica Acta, (1989), 164, 73-84. A determination of whether one macrocycle is more rigid than
another can be often made by simply making a molecular model, thus it is not in general
essential to know configurational energies in absolute terms or to precisely compute
them. Excellent comparative determinations of rigidity of one macrocycle vs. another
can be made using inexpensive personal computer-based computational tools, such as
ALCHEMY III, commercially available from Tripos Associates. Tripos also has available
more expensive software permitting not only comparative, but absolute determinations;
alternately, SHAPES can be used (see Zimmer cited supra). One observation which is
significant in the context of the present invention is that there is an optimum for
the present purposes when the parent macrocycle is distinctly flexible as compared
to the cross-bridged form. Thus, unexpectedly, it is preferred to use parent macrocycles
containing at least four donor atoms, such as cyclam derivatives, and to cross-bridge
them, rather than to start with a more rigid parent macrocycle. Another observation
is that cross-bridged macrocycles are significantly preferred over macrocycles which
are bridged in other manners.
Preferred MRL's herein are a special type of ultra-rigid ligand which is cross-bridged.
A "cross-bridge" is nonlimitingly illustrated in 1.11 hereinbelow. In 1.11, the cross-bridge
is a -CH
2CH
2- moiety. It bridges N
1 and N
8 in the illustrative structure. By comparison, a "same-side" bridge, for example if
one were to be introduced across N
1 and N
12 in 1.11, would not be sufficient to constitute a "cross-bridge" and accordingly would
not be preferred.
Suitable metals in the rigid ligand complexes include Mn(II), Mn(III), Mn(IV),
Mn(V), Fe(II), Fe(III), Fe(IV), Co(I), Co(II), Co(III), Ni(I), Ni(II), Ni(III), Cu(I),
Cu(II), Cu(III), Cr(II), Cr(III), Cr(IV), Cr(V), Cr(VI), V(III), V(IV), V(V), Mo(IV),
Mo(V), Mo(VI), W(IV), W(V), W(VI), Pd(II), Ru(II), Ru(III), and Ru(IV). Preferred
transition-metals in the instant transition-metal bleach catalyst include manganese,
iron and chromium. Preferred oxidation states include the (II) and (III) oxidation
states. Manganese(II) in both the low-spin configuration and high spin complexes are
included. It is to be noted that complexes such as low-spin Mn(II) complexes are rather
rare in all of coordination chemistry. The designation (II) or (III) denotes a coordinated
transition metal having the requisite oxidation state; the coordinated metal atom
is not a free ion or one having only water as a ligand.
In general, as used herein, a "ligand" is any moiety capable of direct covalent
bonding to a metal ion. Ligands can be charged or neutral and may range widely, including
simple monovalent donors, such as chloride, or simple amines which form a single coordinate
bond and a single point of attachment to a metal; to oxygen or ethylene, which can
form a three-membered ring with a metal and thus can be said to have two potential
points of attachment, to larger moieties such as ethylenediamine or aza macrocycles,
which form up to the maximum number of single bonds to one or more metals that are
allowed by the available sites on the metal and the number of lone pairs or alternate
bonding sites of the free ligand. Numerous ligands can form bonds other than simple
donor bonds, and can have multiple points of attachment.
Ligands useful herein can fall into several groups: the MRL, preferably a cross-bridged
macropolycycle (preferably there will be one MRL in a useful transition-metal complex,
but more, for example two, can be present, but not in preferred mononuclear transition-metal
complexes); other, optional ligands, which in general are different from the MRL (generally
there will be from 0 to 4, preferably from 1 to 3 such ligands); and ligands associated
transiently with the metal as part of the catalytic cycle, these latter typically
being related to water, hydroxide, oxygen or peroxides. Ligands of the third group
are not essential for defining the metal bleach catalyst, which is a stable, isolable
chemical compound that can be fully characterized. Ligands which bind to metals through
donor atoms each having at least a single lone pair of electrons available for donation
to a metal have a donor capability, or potential denticity, at least equal to the
number of donor atoms. In general, that donor capability may be fully or only partially
exercised.
Generally, the MRL's herein can be viewed as the result of imposing additional
structural rigidity on specifically selected "parent macrocycles".
More generally, the MRL's (and the corresponding transition-metal catalysts) herein
suitably comprise:
(a) at least one macrocycle main ring comprising four or more heteroatoms; and
(b) a covalently connected non-metal superstructure capable of increasing the rigidity
of the macrocycle, preferably selected from
(i) a bridging superstructure, such as a linking moiety;
(ii) a cross-bridging superstructure, such as a cross-bridging linking moiety; and
(iii) combinations thereof.
The term "superstructure" is used herein as defined in the literature by Busch
et al., see, for example, articles by Busch in "Chemical Reviews".
[0109] Preferred superstructures herein not only enhance the rigidity of the parent macrocycle,
but also favor folding of the macrocycle so that it co-ordinates to a metal in a cleft.
Suitable superstructures can be remarkably simple, for example a linking moiety such
as any of those illustrated in 1.9 and 1.10 below, can be used.

wherein n is an integer, for example from 2 to 8, preferably less than 6, typically
2 to 4, or

wherein m and n are integers from 1 to 8, more preferably from 1 to 3; Z is N
or CH; and T is a compatible substituent, for example H, alkyl, trialkylammonium,
halogen, nitro, sulfonate, or the like. The aromatic ring in 1.10 can be replaced
by a saturated ring, in which the atom in Z connecting into the ring can contain N,
O, S or C.
Without intending to be limited by theory, it is believed that the preorganization
built into the MRL's herein that leads to extra kinetic and/or thermodynamic stability
of their metal complexes arises from either or both of topological constraints and
enhanced rigidity (loss of flexibility) compared to the free parent macrocycle which
has no superstructure. The MRL's as defined herein and their preferred cross-bridged
sub-family, which can be said to be "ultra-rigid", combine two sources of fixed preorganization.
In preferred MRL's herein, the linking moieties and parent macrocycle rings are combined
to form ligands which have a significant extent of "fold", typically greater than
in many known superstructured ligands in which a superstructure is attached to a largely
planar, often unsaturated macrocycle. See, for example: D.H. Busch,
Chemical Reviews, (1993),
93, 847 - 880. Further, the preferred MRL's herein have a number of particular properties,
including (1) they are characterized by very high proton affinities, as in so-called
"proton sponges"; (2) they tend to react slowly with multivalent transition metals,
which when combined with (1) above, renders synthesis of their complexes with certain
hydrolyzable metal ions difficult in hydroxylic solvents; (3) when they are coordinated
to transition metal atoms as identified herein, the MRL's result in complexes that
have exceptional kinetic stability such that the metal ions only dissociate extremely
slowly under conditions that would destroy complexes with ordinary ligands; and (4)
these complexes have exceptional thermodynamic stability; however, the unusual kinetics
of MRL dissociation from the transition metal may defeat conventional equilibrium
measurements that might quantitate this property.
In one aspect of the present invention, the MRL's include those comprising:
(i) an organic macrocycle ring containing four or more donor atoms (preferably at
least 3, more preferably at least 4, of these donor atoms are N) separated from each
other by covalent linkages of at least one, preferably 2 or 3, non-donor atoms, two
to five (preferably three to four, more preferably four) of these donor atoms being
coordinated to the same transition metal in the complex; and
(ii) a linking moiety, preferably a cross-bridging chain, which covalently connects
at least 2 (preferably non-adjacent) donor atoms of the organic macrocycle ring, said
covalently connected (preferably non-adjacent) donor atoms being bridgehead donor
atoms which are coordinated to the same transition metal in the complex, and wherein
said linking moiety (preferably a cross-bridged chain) comprises from 2 to 10 atoms
(preferably the cross-bridged chain is selected from 2, 3 or 4 non-donor atoms, and
4-6 non-donor atoms with a further donor atom).
Suitable MRL's are further nonlimitingly illustrated by the following compound:

[0110] This is a MRL in accordance with the invention which is a highly preferred, cross-bridged,
methyl-substituted (all nitrogen atoms tertiary) derivative of cyclam. Formally, this
ligand is named 5,12-dimethyl-1,5,8,12-tetraazabicyclo[6.6.2]hexadecane using the
extended von Baeyer system. See "A Guide to IUPAC Nomenclature of Organic Compounds:
Recommendations 1993", R. Panico, W.H. Powell and J-C Richer (Eds.), Blackwell Scientific
Publications, Boston, 1993; see especially section R-2.4.2.1. According to conventional
terminology, N1 and N8 are "bridgehead atoms"; as defined herein, more particularly
"bridgehead donor atoms" since they have lone pairs capable of donation to a metal.
N1 is connected to two non-bridgehead donor atoms, N5 and N12, by distinct saturated
carbon chains 2,3,4 and 14,13 and to bridgehead donor atom N8 by a "linking moiety"
a,b which here is a saturated carbon chain of two carbon atoms. N8 is connected to
two non-bridgehead donor atoms, N5 and N12, by distinct chains 6,7 and 9,10,11. Chain
a,b is a "linking moiety" as defined herein, and is of the special, preferred type
referred to as a "cross-bridging" moiety. The "macrocyclic ring" of the ligand supra,
or "main ring" (IUPAC), includes all four donor atoms and chains 2,3,4; 6,7; 9,10,11
and 13,14 but not a,b. This ligand is conventionally bicyclic. The short bridge or
"linking moiety" a,b is a "cross-bridge" as defined herein, with a,b bisecting the
macrocyclic ring.
The MRL's herein are of course not limited to being synthesized from any preformed
macrocycle plus preformed "rigidizing" or "conformation-modifying" element: rather,
a wide variety of synthetic means, such as template syntheses, are useful. See for
example Busch et al., reviewed in "Heterocyclic compounds: Aza-crown macrocycles",
J.S. Bradshaw et. al.
Transition-metal bleach catalysts useful in the invention compositions can in general
include known compounds where they conform with the definition herein, as well as,
more preferably, any of a large number of novel compounds expressly designed for the
present laundry or cleaning uses, and non-limitingly illustrated by any of the following:

[0111] The practitioner may further benefit if certain terms receive additional definition
and illustration. As used herein, "macrocyclic rings" are covalently connected rings
formed from four or more donor atoms (i.e., heteroatoms such as nitrogen or oxygen)
with carbon chains connecting them, and any macrocycle ring as defined herein must
contain a total of at least ten, preferably at least twelve, atoms in the macrocycle
ring. A MRL herein may contain more than one ring of any sort per ligand, but at least
one macrocycle ring must be identifiable. Moreover, in the preferred embodiments,
no two hetero-atoms are directly connected. Preferred transition-metal bleach catalysts
are those wherein the MRL comprises an organic macrocycle ring (main ring) containing
at least 10-20 atoms, preferably 12-18 atoms, more preferably from 12 to 20 atoms,
most preferably 12 to 16 atoms.
"Donor atoms" herein are heteroatoms such as nitrogen, oxygen, phosphorus or sulfur,
which when incorporated into a ligand still have at least one lone pair of electrons
available for forming a donor-acceptor bond with a metal. Preferred transition-metal
bleach catalysts are those wherein the donor atoms in the organic macrocycle ring
of the cross-bridged MRL are selected from the group consisting of N, O, S, and P,
preferably N and O, and most preferably all N. Also preferred are cross-bridged MRL's
comprising 4 or 5 donor atoms, all of which are coordinated to the same transition
metal. Most preferred transition-metal bleach catalysts are those wherein the cross-bridged
MRL comprises 4 nitrogen donor atoms all coordinated to the same transition metal,
and those wherein the cross-bridged MRL comprises 5 nitrogen atoms all coordinated
to the same transition metal.
"Non-donor atoms" of the MRL herein are most commonly carbon, though a number of
atom types can be included, especially in optional exocyclic substituents (such as
"pendant" moieties, illustrated hereinafter) of the macrocycles, which are neither
donor atoms for purposes essential to form the metal catalysts, nor are they carbon.
Thus, in the broadest sense, the term "non-donor atoms" can refer to any atom not
essential to forming donor bonds with the metal of the catalyst. Examples of such
atoms could include heteroatoms such as sulfur as incorporated in a non-coordinatable
sulfonate group, phosphorus as incorporated into a phosphonium salt moiety, phosphorus
as Incorporated into a P(V) oxide, a non-transition metal, or the like. In certain
preferred embodiments, all non-donor atoms are carbon.
Transition metal complexes of MRL's can be prepared in any convenient manner. Two
such preparations are illustrated as follows:
Synthesis of [Mn(Bcyclam)Cl2]
[0112]

(a) Method I.
[0113] "Bcyclam" (5,12-dimethyl-1,5,8,12-tetraaza-bicyclo[6.6.2]hexadecane) is prepared
by a synthesis method described by G.R. Weisman, et al.,
J.Amer.Chem.Soc., (1990),
112, 8604. Bcyclam (1.00 g., 3.93 mmol) is dissolved in dry CH
3CN (35 mL, distilled from CaH
2). The solution is then evacuated at 15 mm until the CH
3CN begins to boil. The flask is then brought to atmospheric pressure with Ar. This
degassing procedure is repeated 4 times. Mn(pyridine)
2Cl
2 (1.12 g., 3.93 mmol), synthesized according to the literature procedure of H. T.
Witteveen et al.,
J. Inorg. Nucl. Chem., (1974),
36, 1535, is added under Ar. The cloudy reaction solution slowly begins to darken. After
stirring overnight at room temperature, the reaction solution becomes dark brown with
suspended fine particulates. The reaction solution is filtered with a 0.2µ filter.
The filtrate is a light tan color. This filtrate is evaporated to dryness using a
rotoevaporator. After drying overnight at 0.05 mm at room temperature, 1.35 g. off-white
solid product is collected, 90% yield.
Elemental Analysis: %Mn, 14.45; %C, 44.22; %H, 7.95; theoretical for [Mn(Bcyclam)Cl
2], MnC
14H
30N
4Cl
2, MW = 380.26. Found: %Mn, 14.98; %C, 44.48; %H, 7.86; Ion Spray Mass Spectroscopy
shows one major peak at 354 mu corresponding to [Mn(Bcyclam)(formate)]
+.
(b) Method II.
[0114] Freshly distilled Bcyclam (25.00 g., 0.0984 mol), which is prepared by the same method
as above, is dissolved in dry CH
3CN (900 mL, distilled from CaH
2). The solution is then evacuated at 15 mm until the CH
3CN begins to boil. The flask is then brought to atmospheric pressure with Ar. This
degassing procedure is repeated 4 times. MnCl
2 (11.25 g., 0.0894 mol) is added under Ar. The cloudy reaction solution immediately
darkens. After stirring 4 hrs. under reflux, the reaction solution becomes dark brown
with suspended fine particulates. The reaction solution is filtered through a 0.2µ
filter under dry conditions. The filtrate is a light tan color. This filtrate is evaporated
to dryness using a rotoevaporator. The resulting tan solid is dried overnight at 0.05
mm at room temperature. The solid is suspended in toluene (100 mL) and heated to reflux.
The toluene is decanted off and the procedure is repeated with another 100 mL of toluene.
The balance of the toluene is removed using a rotoevaporator. After drying overnight
at.05 mm at room temperature, 31.75 g. of a light blue solid product is collected,
93.5% yield.
Elemental Analysis: %Mn, 14.45; %C, 44.22; %H, 7.95; %N, 14.73; %Cl, 18.65; theoretical for [Mn(Bcyclam)Cl
2], MnC
14H
30N
4Cl
2, MW = 380.26. Found: %Mn, 14.69; %C, 44.69; %H, 7.99; %N, 14.78; %Cl, 18.90 (Karl
Fischer Water, 0.68%). Ion Spray Mass Spectroscopy shows one major peak at 354 mu
corresponding to [Mn(Bcyclam)(formate)]
+.
[0115] Bleaching agents other than oxygen bleaching agents are also known in the art and
can be utilized herein. One type of non-oxygen bleaching agent of particular interest
includes photoactivated bleaching agents such as the sulfonated zinc and/or aluminum
phthalocyanines. These materials can be deposited upon the substrate during the washing
process. Upon irradiation with light, in the presence of oxygen, such as by hanging
clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated
and, consequently, the substrate is bleached. Preferred zinc phthalocyanine and a
photoactivated bleaching process are described in U.S. Patent 4,033,718. Typically,
detergent compositions will contain 0.025% to 1.25%, by weight, of sulfonated zinc
phthalocyanine.
Color care and fabric care benefits
[0116] Technologies which provide a type of color care benefit can also be included. Examples
of these technologies are metallo catalysts for color maintenance. Such metallo catalysts
are described in copending European Patent Application EP 596 184. Dye fixing agents,
polyolefin dispersion for anti-wrinkles and improved water absorbancy, perfume and
amino-functional polymer for color care treatment and perfume substantivity are further
examples of color care / fabric care technologies and are described in the co-pending
Patent Application EP 841 390, filed November 07, 1996.
[0117] Fabric softening agents can also be incorporated into cleaning compositions in accordance
with the present invention. These agents may be inorganic or organic in type. Inorganic
softening agents are exemplified by the smectite clays disclosed in GB-A-1 400 898
and in USP 5,019,292. Organic fabric softening agents include the water insoluble
tertiary amines as disclosed In GB-A1 514 276 and EP-B0 011 340 and their combination
with mono C12-C14 quaternary ammonium salts are disclosed in EP-B-0 026 527 and EP-B-0
026 528 and di-long-chain amides as disclosed in EP-B-0 242 919. Other useful organic
ingredients of fabric softening systems include high molecular weight polyethylene
oxide materials as disclosed in EP-A-0 299 575 and 0 313 146.
[0118] Levels of smectite clay are normally in the range from 2% to 20%, more preferably
from 5% to 15% by weight, with the material being added as a dry mixed component to
the remainder of the formulation. Organic fabric softening agents such as the water-insoluble
tertiary amines or dilong chain amide materials are incorporated at levels of from
0.5% to 5% by weight, normally from 1% to 3% by weight whilst the high molecular weight
polyethylene oxide materials and the water soluble cationic materials are added at
levels of from 0.1% to 2%, normally from 0.15% to 1.5% by weight. These materials
are normally added to the spray dried portion of the composition, although in some
instances it may be more convenient to add them as a dry mixed particulate, or spray
them as molten liquid on to other solid components of the composition.
Builder system
[0119] The compositions according to the present invention may further comprise a builder
system. Any conventional builder system is suitable for use herein including aluminosilicate
materials, silicates, polycarboxylates, alkyl- or alkenyl-succinic acid and fatty
acids, materials such as ethylenediamine tetraacetate, diethylene triamine pentamethyleneacetate,
metal ion sequestrants such as aminopolyphosphonates, particularly ethylenediamine
tetramethylene phosphonic acid and diethylene triamine pentamethylenephosphonic acid.
Phosphate builders can also be used herein.
[0120] Suitable builders can be an inorganic ion exchange material, commonly an inorganic
hydrated aluminosilicate material, more particularly a hydrated synthetic zeolite
such as hydrated zeolite A, X, B, HS or MAP.
Another suitable inorganic builder material is layered silicate, e.g. SKS-6 (Hoechst).
SKS-6 is a crystalline layered silicate consisting of sodium silicate (Na
2Si
2O
5).
Suitable polycarboxylates containing one carboxy group include lactic acid, glycolic
acid and ether derivatives thereof as disclosed in Belgian Patent Nos. 831,368, 821,369

840,623. Polycarboxylates containing three carboxy groups include, in particular,
water-soluble citrates, aconitrates and citraconates as well as succinate derivatives
such as the carboxymethyloxysuccinates described in British Patent No. 1,379,241,
lactoxysuccinates described in Netherlands Application 7205873, and the oxypolycarboxylate
materials such as 2-oxa-1,1,3-propane tricarboxylates described in British Patent
No. 1,387,447.
[0121] Polycarboxylates containing four carboxy groups include oxydisuccinates disclosed
in British Patent No. 1,261,829, 1,1,2,2-ethane tetracarboxylates, 1,1,3,3-propane
tetracarboxylates and 1,1,2,3-propane tetracarboxylates. Polycarboxylates containing
sulfo substituents include the sulfosuccinate derivatives disclosed in British Patent
Nos. 1,398,421 and 1,398,422 and in U.S. Patent No. 3,936,448, and the sulfonated
pyrolysed citrates described in British Patent No. 1,082,179, while polycarboxylates
containing phosphone substituents are disclosed in British Patent No. 1,439,000.
[0122] Alicyclic and heterocyclic polycarboxylates include cyclopentane-cis,cis,cis-tetracarboxylates,
cyclopentadienide pentacarboxylates, 2,3,4,5-tetrahydro-furan - cis, cis, cis-tetracarboxylates,

1,2,3,4,5,6-hexane - hexacar-boxylates and and carboxymethyl derivatives of polyhydric
alcohols such as sorbitol, mannitol and xylitol. Aromatic poly-carboxylates include
mellitic acid, pyromellitic acid and the phthalic acid derivatives disclosed in British
Patent No. 1,425,343.
Of the above, the preferred polycarboxylates are hydroxycarboxylates containing
up to three carboxy groups per molecule, more particularly citrates.
[0123] Preferred builder systems for use in the present compositions include a mixture of
a water-insoluble aluminosilicate builder such as zeolite A or of a layered silicate
(SKS-6), and a water-soluble carboxylate chelating agent such as citric acid.
[0124] Preferred builder systems include a mixture of a water-insoluble aluminosilicate
builder such as zeolite A, and a watersoluble carboxylate chelating agent such as
citric acid. Preferred builder systems for use in liquid detergent compositions of
the present invention are soaps and polycarboxylates.
[0125] Other builder materials that can form part of the builder system for use in granular
compositions include inorganic materials such as alkali metal carbonates, bicarbonates,
silicates, and organic materials such as the organic phosphonates, amino polyalkylene
phosphonates and amino polycarboxylates.
[0126] Other suitable water-soluble organic salts are the homo- or co-polymeric acids or
their salts, in which the polycarboxylic acid comprises at least two carboxyl radicals
separated from each other by not more than two carbon atoms. Polymers of this type
are disclosed in GB-A-1,596,756. Examples of such salts are polyacrylates of MW 2000-5000
and their copolymers with maleic anhydride, such copolymers having a molecular weight
of from 20,000 to 70,000, especially about 40,000.
[0127] Detergency builder salts are normally included in amounts of from 5% to 80% by weight
of the composition preferably from 10% to 70% and most usually from 30% to 60% by
weight.
Chelating Agents
[0128] The detergent compositions herein may also optionally contain one or more iron and/or
manganese chelating agents. Such chelating agents can be selected from the group consisting
of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating
agents and mixtures therein, all as hereinafter defined. Without intending to be bound
by theory, it is believed that the benefit of these materials is due in part to their
exceptional ability to remove iron and manganese ions from washing solutions by formation
of soluble chelates.
[0129] Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates,
N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates,
triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines,
alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.
[0130] Amino phosphonates are also suitable for use as chelating agents in the compositions
of the invention when at lease low levels of total phosphorus are permitted in detergent
compositions, and include ethylenediaminetetrakis (methylenephosphonates) as DEQUEST.
Preferred, these amino phosphonates to not contain alkyl or alkenyl groups with more
than 6 carbon atoms.
[0131] Polyfunctionally-substituted aromatic chelating agents are also useful in the compositions
herein. See U.S. Patent 3,812,044, issued May 21, 1974, to Connor et al. Preferred
compounds of this type in acid form are dihydroxydisulfobenzenes such as 1,2-dihydroxy-3,5-disulfobenzene.
[0132] A preferred biodegradable chelator for use herein is ethylenediamine disuccinate
("EDDS"), especially the [S.S] isomer as described in U.S. Patent 4,704,233, November
3, 1987, to Hartman and Perkins.
[0133] The compositions herein may also contain water-soluble methyl glycine diacetic acid
(MGDA) salts (or acid form) as a chelant or co-builder useful with, for example, insoluble
builders such as zeolites, layered silicates and the like.

propane-diol. The target is to obtain a polymer capped at both end by sulphobenzoate
groups, "primarily", in the present context most of said copolymers herein will be
end-capped by sulphobenzoate groups. However, some copolymers will be less than fully
capped, and therefore their end groups may consist of monoester of ethylene glycol
and/or propane 1-2 diol, thereof consist "secondarily" of such species.

[0146] Is is well known in the art that free chlorine in tap water rapidly deactivates the
enzymes comprised in detergent compositions. Therefore, using chlorine scavenger such
as perborate, ammonium sulfate, sodium sulphite or polyethyleneimine at a level above
0.1% by weight of total composition, in the formulas will provide improved through
the wash stability of the detergent enzymes. Compositions comprising chlorine scavenger
are described in the European patent application EP 553 607 filed January 31, 1992.

W.F. Masler, Cosmetics and Toiletries, volume 104, pages 71-73, (1989). The LSDP is
the % weight ratio of dispersing agent to sodium oleate required to disperse the lime
soap deposits formed by 0.025g of sodium oleate in 30ml of water of 333ppm CaCo
3 (Ca:Mg=3:2) equivalent hardness.
