[0001] This application contains a Sequence Listing in computer readable form, which is
incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present disclosure relates to cleaning compositions comprising a specific glycoside
hydrolase enzyme. The present disclosure also relates to methods of making and using
such cleaning compositions. The present disclosure also relates to the use of the
glycoside hydrolase enzyme.
BACKGROUND OF THE INVENTION
[0003] The detergent formulator is constantly aiming to improve the performance of detergent
compositions. One particular challenge is the removal of certain soils of microbial
origin from surfaces such as textiles. Such soils can be sticky and difficult to remove.
Furthermore, because they are sticky they tend to adhere body soils and/or particulate
soils to the surface, making soil removal difficult and having a tendency to build
up over time. This may be particularly noticeable for example on collars and cuffs
where incomplete cleaning may occur.
[0004] There is a need for improved cleaning compositions which provide cleaning of such
soils. The present inventors have found that this problem may be ameliorated by cleaning
compositions comprising certain glycoside hydrolases. Glycosyl hydrolases are enzymes
that catalyze the hydrolysis of the glycosyl bond to release smaller sugars. There
are over 100 classes of glycosyl hydrolase and many different enzymes fall within
the class of glycosyl hydrolases, for example cellulases and xyloglucanases which
can be used in cleaning compositions. Surprisingly, certain specific glycosyl hydrolases
can provide particularly improved cleaning.
[0005] Glycoside hydrolases are described by
Coutinho, P.M. and Henrissat, B., 1999, Carbohydrate-active enzymes: an integrated
database approach, in "Recent Advances In Carbohydrate Bioengineering", H.J. Gilbert,

pp. 3-12.

Methods of Making the Composition
[0123] The present disclosure relates to methods of making the compositions described herein.
The compositions of the invention may be solid (for example granules or tablets) or
liquid form. It may be preferred for the compositions to be in liquid form. They may
be made by any process chosen by the formulator, including by a batch process, a continuous
loop process, or combinations thereof.
[0124] When in the form of a liquid, the compositions of the invention may be aqueous (typically
above 2 wt% or even above 5 or 10 wt% total water, up to 90 or up to 80wt% or 70 wt%
total water) or non-aqueous (typically below 2 wt% total water content). Typically
the compositions of the invention will be in the form of an aqueous solution or uniform
dispersion or suspension of optical brightener, DTI and optional additional adjunct
materials, some of which may normally be in solid form, that have been combined with
the normally liquid components of the composition, such as the liquid alcohol ethoxylate
nonionic, the aqueous liquid carrier, and any other normally liquid optional ingredients.
Such a solution, dispersion or suspension will be acceptably phase stable. When in
the form of a liquid, the detergents of the invention preferably have viscosity from
1 to 1500 centipoises (1-1500 mPa*s), more preferably from 100 to 1000 centipoises
(100-1000 mPa*s), and most preferably from 200 to 500 centipoises (200-500 mPa*s)
at 20s-1 and 21°C. Viscosity can be determined by conventional methods. Viscosity
may be measured using an AR 550 rheometer from TA instruments using a plate steel
spindle at 40 mm diameter and a gap size of 500 µm. The high shear viscosity at 20s-1
and low shear viscosity at 0.05-1 can be obtained from a logarithmic shear rate sweep
from 0.1-1 to 25-1 in 3 minutes time at 21C. The preferred rheology described therein
may be achieved using internal existing structuring with detergent ingredients or
by employing an external rheology modifier. More preferably the detergents, such as
detergent liquid compositions have a high shear rate viscosity of from about 100 centipoise
to 1500 centipoise, more preferably from 100 to 1000 cps. Unit Dose detergents, such
as detergent liquid compositions have high shear rate viscosity of from 400 to 1000cps.
Detergents such as laundry softening compositions typically have high shear rate viscosity
of from 10 to 1000, more preferably from 10 to 800 cps, most preferably from 10 to
500 cps. Hand dishwashing compositions have high shear rate viscosity of from 300
to 4000 cps, more preferably 300 to 1000 cps.
[0125] The cleaning and/or treatment compositions in the form of a liquid herein can be
prepared by combining the components thereof in any convenient order and by mixing,
e.g., agitating, the resulting component combination to form a phase stable liquid
detergent composition. In a process for preparing such compositions, a liquid matrix
is formed containing at least a major proportion, or even substantially all, of the
liquid components, e.g., nonionic surfactant, the non-surface active liquid carriers
and other optional liquid components, with the liquid components being thoroughly
admixed by imparting shear agitation to this liquid combination. For example, rapid
stirring with a mechanical stirrer may usefully be employed. While shear agitation
is maintained, substantially all of any anionic surfactants and the solid form ingredients
can be added. Agitation of the mixture is continued, and if necessary, can be increased
at this point to form a solution or a uniform dispersion of insoluble solid phase
particulates within the liquid phase. After some or all of the solid-form materials
have been added to this agitated mixture, particles of any enzyme material to be included,
e.g., enzyme granulates, are incorporated. As a variation of the composition preparation
procedure hereinbefore described, one or more of the solid components may be added
to the agitated mixture as a solution or slurry of particles premixed with a minor
portion of one or more of the liquid components. After addition of all of the composition
components, agitation of the mixture is continued for a period of time sufficient
to form compositions having the requisite viscosity and phase stability characteristics.
Frequently this will involve agitation for a period of from about 30 to 60 minutes.
[0126] The adjunct ingredients in the compositions of this invention may be incorporated
into the composition as the product of the synthesis generating such components, either
with or without an intermediate purification step. Where there is no purification
step, commonly the mixture used will comprise the desired component or mixtures thereof
(and percentages given herein relate to the weight percent of the component itself
unless otherwise specified) and in addition unreacted starting materials and impurities
formed from side reactions and/or incomplete reaction. For example, for an ethoxylated
or substituted component, the mixture will likely comprise different degrees of ethoxylation/substitution.
Method of Use
[0127] The present disclosure relates to a method of using the cleaning composition of the
present disclosure to clean a surface, such as a textile. In general, the method includes
mixing the cleaning composition as described herein with water to form an aqueous
liquor and contacting a surface, preferably a textile, with the aqueous liquor in
a laundering step. The target surface may include a greasy soil or body soil.
[0128] The present invention also provides use of a composition comprising an amylase enzyme
and an enzyme having glycoside hydrolase activity belonging to the endo-alpha-1,4-polygalactosminidase
class (EC 3.2.1.109) of enzymes for enhanced stain removal from a surface, preferably

malodour. Preferably the glycoside hydrolase enzyme is a variant having at least 60%
or 65% or 70% or 75% or 80% or 85% or 90% or 95% identity to 100% SEQ ID NO:1.
[0129] The compositions of this invention, typically prepared as hereinbefore described,
can be used to form aqueous (washing/treatment) liquor for use in the laundering/treatment
of fabrics and/or hard surfaces. Generally, an effective amount of such a composition
is added to water, for example in a conventional fabric automatic washing machine,
to form such aqueous liquor. The aqueous liquor so formed is then contacted, typically
under agitation, with the fabrics to be laundered/treated therewith. An effective
amount of the cleaning composition herein added to water to form aqueous liquor can
comprise amounts sufficient to form from about 500 to 25,000 ppm, or from 500 to 15,000
ppm of composition in the aqueous liquor, or from about 1,000 to 3,000 ppm of the
cleaning composition herein will be provided in aqueous liquor.
[0130] Typically, the aqueous liquor is formed by contacting the cleaning composition with
wash water in such an amount so that the concentration of the anionic surfactant in
the wash liquor is from above 0.1g/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 hand-wash laundry application. In these
applications, the aqueous liquor formed and concentration of cleaning 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 aqueous liquor.
[0131] The aqueous liquor may comprise 40 litres or less of water, or 30 litres or less,
or 20 litres or less, or 10 litres or less, or 8 litres or less, or even 6 litres
or less of water. The aqueous liquor may comprise from above 0 to 15 litres, or from
2 litres, and to 12 litres, or even to 8 litres of water. Typically from 0.01kg to
2kg of fabric per litre of aqueous liquor is dosed into said aqueous 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 litre of aqueous liquor is dosed into said aqueous
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 aqueous liquor. Such compositions
are typically employed at concentrations of from about 500 ppm to about 15,000 ppm
in solution. The water temperature typically ranges from about 5 °C to about 90 °C
for example from 20 °C to 60 °C, preferably up to 40 °C or 30 °C and, when laundering
fabric, the water to fabric ratio is typically from about 1:1 to about 30:1. Typically
the aqueous liquor comprising the cleaning composition of the invention has a pH of
from 3 to 11.5, typically from 7 to 11, more usually 8 to 10.5.
[0132] 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,
with an optional drying step.
[0133] Drying of such surfaces or fabrics may be accomplished by any one of the common means
employed either in domestic or industrial settings: machine drying or open-air drying.
The fabric may comprise any fabric capable of being laundered in normal consumer or
institutional use conditions, and the invention is particularly suitable for synthetic
textiles such as polyester and nylon and especially for treatment of mixed fabrics
and/or fibres comprising synthetic and cellulosic fabrics and/or fibres. As examples
of synthetic fabrics are polyester, nylon, these may be present in mixtures with cellulosic
fibres, for example, polycotton fabrics.
