  • Cyclomaltodextrin glucanotransferase is a transferase that exhibits several different actions on starch. It produces from starch ⁇ , ⁇ , and ⁇ cyclodextrins, hydrolyzes starch and cross links starch. In these types of reactions, ⁇ sugars are both donor and acceptor for the transferase reaction. Up to now, it was not clear if these transferase enzymes could covalently link sugar units to cotton.

Description

LAUNDRY DETERGENT AND/OR FABRIC CARE COMPOSITIONS COMPRISING A TRANSFERASE
Field of the Invention
The present invention relates to laundry detergent and/or fabric care compositions comprising a transferase.
Background of the invention
Laundry detergent and/or fabric care compositions are well-known in the art and extensively represented in the market place.
Laundry detergent compositions include nowadays a complex combination of active ingredients which fulfil certain specific needs : a surfactant system, enzymes providing cleaning and fabric care benefits, bleaching agents, a builder system, suds suppressors, soil-suspending agents, soil-release agents, optical brighteners, softening agents, dispersants, dye transfer inhibition compounds, abrasives, bactericides, perfumes, and their overall performance has indeed improved over the years.
However, the complex nature of everyday "body" soils typically found on pillow cases, T-shirts, collars and socks, provides a continuous thorough cleaning challenge for detergents. These soils are difficult to remove completely and often residues build up on fabric leading to dinginess and yellowing. In addition, removal by detergents of stains stemming from plants, wood, mud-clay based soil and fruits is one of the toughest cleaning challenges, in particular with the tendency to move to low wash temperatures and shorter washing cycles. These stains typically contain complex mixtures of fibrous material, based mainly on carbohydrates and their derivatives, fibre and cell wall components. Such stains are generally accompanied by amylose, sugars and their derivatives.
In recent years, consumer desirability for fabric conditioning compositions has risen. Fabric softening compositions impart several desirable properties to treated garments including softness and static control. Fabric softness of laundered garments is typically achieved by delivering a quaternary ammonium compound to the surface of the fabric.
Consumer desirability for durable press fabric garments, particularly cotton fabric garments, has also risen. Durable press garments include those garments which resist wrinkling of the fabric both during wear and during the laundering process. Durable press garments can greatly decrease the hand work associated with laundering by eliminating ironing or reducing ironing time sometimes necessary to prevent wrinkling of the garment. However, in most commercially available durable press fabrics, the fabric's ability to resist wrinkling is reduced over time as the garment is repeatedly worn and laundered.
Furthermore, coloured garments have a tendency to wear and show appearance losses. A portion of this colour loss may be attributed to abrasion in the laundering process, particularly in automatic washing machines and automatic laundry dryers.
Moreover, tensile strength loss of fabric appears as an unavoidable result of mechanical / chemical action due to use / wearing or washing.
As indicated above, there is a continuous need for a laundry detergent composition which provides excellent fabric cleaning and/or fabric stain removal, especially on body soils and plant based stains and/or fabric whiteness maintenance and/or fabric color appearance and/or dye transfer inhibition.
In addition, there is a continuous need for a laundry detergent composition and/or fabric care composition, which can provide, refurbish or restore tensile strength, anti- wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, as well as provide static control, fabric softness, colour appearance and fabric anti-wear properties and benefits.
The above objectives have been met by formulating laundry detergent and/or fabric care compositions comprising a transferase.
It is a further object of the present invention to provide detergent composition and/or fabric care composition comprising transferase enzyme, which can provide, refurbish or restore improved tensile strength, enhanced anti-wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, as well as provide better static control, fabric softness, colour appearance and fabric anti-wear properties and benefits, while providing improved cleaning benefits. The above objective has been met by formulating laundry detergent and/or fabric care compositions further comprising a surfactant selected from nonionic and/or anionic and/or cationic and or mixtures thereof, a detergent enzyme, a bleaching agent, a dye transfer inhibiting polymer, a dispersant and/or a smectite clay.
Transferase enzymes have been described in the art :
A process for producing saccharides of a definite chain length such as maltose and maltooligosaccharides in an isolated and highly pure form using a saccharide chain transferase such as cyclodextrin glycosyltransferase or α-amylase, has been disclosed in EP 560 982. These so-produced saccharides are used in the pharmaceutical field.
US 5,516,689 describes an enzyme composition and a means of reducing the stickiness of honey dew contaminated cotton. Transglucosidases and/or pectinases are used to hydrolyse and/or reduce honeydew on cotton fiber for reducing the stickiness of such fiber and avoid severe problems during the milling of cotton.
Microbial transglutaminases, their production and their use in a variety of industrial purposes, including gelling of proteins, improvement of baking quality of flour, producing paste type food material from protein, fat and water, preparation of cheese from milk concentrate, binding of chopped meat, improvement of taste and texture of food proteins, casein finishing in leather processing, shoe shine, etc. have been described in WO96/06931.
JP 7-107971 relates to a micro-organism belonging to the genus Bacillus and having the capacity to produce an alkali resistant cyclodextrin glucanotransferase. Said enzyme can be used in dishwashing applications wherein it demonstrates decomposition and removal of food soils and the produced cyclodextrin plays as a masking, de-odorizing agent. Moreover said alkali resistant cyclodextrin glucanotransferase improves the cleaning capabilities of said compositions by improving the sudsing properties and stimulating the emulsification of the soiling.
Dishwashing detergent compositions containing cyclodextrin glucanotransferase with cleaning benefits and deodorising effect are described in JP 7-109488.
WO 97/23683 relates to the use of xyloglucan endotransglycosylase (XET) to provide strength and/or shape-retention and/or anti- wrinkling properties to cellulosic material.
Nevertheless, none of these documents teaches the cleaning or fabric care benefits obtained by transferase enzymatic activity from transferases nor xyloglucan transferases that exhibit greater transferase activity than hydrolytic activity and/or xyloglucan transferases that exhibit higher reaction rates for donor substrates with higher molecular weight than for donor substrates with lower molecular weight, 4
when used in the laundry and/or fabric care process.
Summary of the invention
The present invention relates to laundry detergent and/or fabric care compositions comprising a transferase for fabric care and/or cleaning benefits.
Detailed description of the invention
The Transferase Enzymes and their Substrates
An essential component of the laundry detergent and/or fabric care compositions of the present invention is a transferase enzyme.
Transferase enzymes catalyse the transfer of functional compounds to a range of substrates. Particularly, the transferase of the invention have the potential to transfer a chemical moiety, for example a methyl group or a glycosyl group, from a small substrate to form oligomeric molecules or elongate polymeric compounds. Using small substrates, the enzyme improves the properties of garments by binding functional groups like methyl, hydroxymethyl, formyl, carboxyl, aldehyde, ketone, acyl, amino and phosphorous functional groups and/or transferring glycosyl residues to the garment surface. The improved garments properties include tensile strength, anti-wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, static control, fabric softness, colour appearance and fabric anti-wear properties and benefits. When the transferase level is high and the substrate concentration is low, the functional groups are transferred to water molecules providing cleaning benefits.
Suitable transferases for the present invention are represented by the EC 2.1 Transferring one-carbon groups enzymes, EC 2.2 Transferring aldehyde or ketone residues enzymes, EC 2.3 Acyltransferases, EC 2.4 Glycosyltransferase, EC 2.5 Transferring alkyl or aryl groups other than methyl groups enzymes, EC 2.6 Transferring nitrogenous groups enzymes and EC 2.7 Transferring phosphorus-containing groups enzymes.

For specific applications, preferred transferases demonstrate some / most of their activity in the alkaline conditions, 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 transferases are enzymes having their maximum activity at a pH ranging from 7 to 12. Other preferred transferase is a transferase having at least 50% of its maximum activity between 10°C and 50°C.
Preferred transferases for the laundry detergent and/or fabric care compositions of the present invention are included in the acyltransferases (EC 2.3) and glycosyltransferases classes ( EC 2.4).
Of particular interest is the group of acyltransferases, especially the aminoacyl transferases (EC 2.3.2). These are enzymes transferring amino groups from a donor, generally an amino acid, to an acceptor. Even more preferred is the protein-glutamine γ- glutamyltransferase (EC 2.3.2.13), also available under the name transglutaminase. Without wishing to be bound by theory, it is believed that enzymatic crosslinking of amino acids, di/tri/poly-peptides and/or proteins will occur on the fabric, resulting in increased tensile strength and improved appearance. Moreover, hydrolysis by an aminoacyl transferase of said substrates present in the soils/stains, will provide cleaning benefits.
Of particular interest is also the group of glycosyltransferases. The general properties of these enzymes is to transfer a sugar from oligosaccharides to another carbohydrate as acceptor. Both hexosyltransferases and pentosyltransferases can be used in the invention. Glycosyltransferases catalyse both hydrolytic and transfer reactions in incubation with oligosaccharides. As a result of the enzymatic activity, oligosaccharides are converted into a new class of polysaccharides. It has been surprisingly found that glycosyltransferases improve the tensile strength and appearance of fabrics, e.g. reduce fabric wrinkles. Without wishing to be limited by any theory, it is indeed believed that due to the glycosyltransferase activity, oligosaccharides are bound to the cellulose polymers of cotton fabrics resulting in improved tensile strength and demonstrating appearance benefits especially after multiple wash cycles.
Without wishing to be bound by theory, the glycosyltransferase activity is believed to have four potential modes of action providing fabric care benefits :
- Enzymatic stitching wherein the enzyme is thought to bind oligosaccharides to cellulose fibers with reduced tensile strength;
- Enzymatic cross-linking wherein the glycosyltransferase is thought to bind cellulose fibers with reduced tensile strength together; and
- Enzymatic polymer linking wherein polymers are linked to cellulose fibers with reduced tensile strength.
In addition, in presence of a low level of substrate and a high level of glycosyltransferase, the glycosyl groups are transferred to water molecules providing cleaning benefits.
For example, transglucosidase is an enzyme that catalyses both hydrolytic and transfer reactions in solutions containing α-D- gluco-oligosaccharides. As a result of the transglucosidase enzymatic reactions, the malto-oligosaccharides are converted to isomalto-oligosaccharides providing a new class of polysaccharides characterised by a higher proportion of saccharides linked by α-D- 1,6 linkages from the non-reducing end.
These transglucosidase reactions have been found to provide fabric care performance. It is believed that the improved tensile strength, the reduced wrinkling and better appearance are due to oligosaccharides bound to the cellulose polymers fibers of cotton.
Examples of suitable glycosyltransferases are galactosyl transferases and fructosyltransferases, such as 1,4-β-galactosyltransferase; 1,3-α-fructosyltransferase; 2,3-sialyl transferase; cyclodextrin glycosyltransferase; N-acetylgluco- or -galactosaminyltransferase; and

Of particular interest is EC 2.4.1.24 1 ,4-α-D-glucan : 1 ,4-a-D-glucan(D-glucose) 6-α-D-glucosyl transferase. A particulate member of this enzyme is commercially available under the name Transglucosidase L-500. In addition to the glycosyltransferases discussed above, it has been found that mutant glycosyltransferases and/or mutant glycosidases, examples of which are described in PCT Application Publication No. WO 97/21822, its Canadian equivalent Canadian Patent No. 2,165,041, and its U.S. equivalent U.S. Patent No. 5,716,812, all to S.G. Withers et al., improve the tensile strength and appearance of fabrics, e.g., reduce fabric wrinkles, enhance shape retention and reduce shrinkage. The mutant forms of glycosyltransferases and/or glycosidases provide enzymatic stitching, enzymatic cross- linking and enzymatic polymer linking, as discussed above in greater detail.
The mutant glycosyltransferases and/or mutant glycosidases only have one nucleophilic amino acid on the active site of the enzyme, rather than two, like non- mutated glycosyltransferases and/or non-mutated glycosidases, respectively. In other words, the mutant glycosyltransferases and/or mutant glycosidases are formed in which one of the normal nucleophilic amino acids within the active site has been changed to a non-nucleophilic amino acid. As a result, the mutant glycosyltransferases and/or mutant glycosidases only exhibit transferase activity; no hydrolytic activity is exhibited by the mutant glycosyltransferases nor the mutant glycosidases. Accordingly, unlike non- mutated glycosyltransferases and/or non-mutated glycosidases, the mutant glycosyltransferases and/or mutant glycosidases convert oligosaccharides into a new class of polysaccharides without the detrimental hydro lyzation of the new class of polysaccharides back into oligosaccharides or without water acting as acceptor for the transfer reaction.
These mutant glycosyltransferases and/or mutant glycosidases can be extracted from plant, yeast, bacteria or other organisms. The DNA of the mutant glycosyltransferases and/or mutant glycosidases can be cloned and expressed in bacteria, yeast or fungi and obtained in this way.
These mutant glycosyltransferases and/or mutant glycosidases can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions, and the like.
In addition to the usefulness of mutant glycosyltransferases and/or mutant glycosidases in laundry detergents and fabric care compositions, they can also be used in solutions for the treatment of fabrics in the textile process industry, and the treatment of paper and paper pulp.
The novel characteristics and properties of the mutated glycosyltransferases and/or the mutated glycosidases make them highly suitable for use in laundry detergent and fabric care compositions because the absence of hydrolytic activity implies no loss in tensile strength of fabrics, even in the absence of donors in the transferase reaction. When mutant glycosyltransferases and or mutant glycosidases are present in the compositions of the present invention, it is desirable that the saccharide concentration in the compositions is in the range of from about 0.01% to 30% by weight of the total composition, more preferably, 1% to 10% by weight of the total composition. Furthermore, the compositions of the present invention can have saccharides of high molecular weight added to the compositions to obtain the benefits discussed above.
Another class of enzymes that is of particular interest is xyloglucan transferases. A preferred xyloglucan transferase is endoxyloglucan transferase ("EXT"), which is described in J. Plant Res. 108, 137-148, 1995 by Nishitani, Kagoma University, and now called "EXGT" in Int. Review of Cytology, Vol. 173, p. 157, 1997 by Nishitani, Kagoma University. EXT is also described in J. Biol. Chem. 267, 21058-21064, 1992 by Nishitani et al.
Like the mutant glycosyltransferases discussed above, this endoxyloglucan transferase improves the tensile strength and appearance of fabrics, e.g., reduce fabric wrinkles, enhance shape retention and reduce shrinkage. The endoxyloglucan transferase stitch cellulose fibrils. These stitching properties of the enzyme on cellulose fibrils delivers the above mentioned benefits.
Endoxyloglucan transferase is responsible for rejoining intermicrofibrillar xyloglucan chains, the xyloglucan chains between cellulosic microfibrils during the formation of plant cell walls. By rejoining the cellulosic microfibrils through xyloglucan linkages, the cellulose structure acquires improved strength of the fibers. Since the structure of fabrics is of cellulosic nature, the enzyme has a stitching activity on the microfibrils. Also shape retention, anti-shrinkage and anti- wrinkle benefits can be explained by the stitching properties of the enzyme.
Endoxyloglucan transferase differs in activity from xyloglucan endotransglycosylase ("XET transferase"), which is described in WO 97/23683 to Novo Nordisk A/S, in Biochem. J. (1992) 282, 821-828 by Fry et al. and in Plant J. (1993) 3(5), 691-700. The difference being that the xyloglucan endotransglycosylase shows both transferase activity and hydrolase ("hydrolytic") activity. In contrast, endoxyloglucan transferase only shows transferase activity. No hydrolase activity is shown by endoxyloglucan transferase. Accordingly, unlike xyloglucan endotransglycosylase, the endoxyloglucan transferase converts oligosaccharides into a new class of polysaccharides without the detrimental hydrolyzation of the new class of polysaccharides back into oligosaccharides.
Furthermore, the endoxyloglucan transferase exhibits strict donor specificity for high molecular weight xyloglucan polymers and does not act on lower molecular weight 10
xyloglucan oligomers. Preferably, endoxyloglucan transferase exhibits strict donor specificity for xyloglucan polymers having molecular weights of at least 10,000.
The novel characteristics and properties of endoxyloglucan transferase make it highly suitable for use in laundry detergent and fabric care compositions because the absence of hydrolytic activity implies no loss in tensile strength of fabrics, even in the absence of donors in the transferase reaction. Furthermore, lower levels of substrate donor can be used. Without desiring to be limited, it is believed that high benefits can be obtained even in the absence of a donor substrate if the endoxyloglucan transferase uses xyloglucans of the primary wall of the cotton fiber within fabrics.
Endoxyloglucan transferase can be extracted from plants and other organisms. Endoxyloglucan transferase can be obtained from a large number of plants including, but not limited to, A. thaliana and V. angularis. Alternatively, the DNA of the enzyme can be cloned and expressed in bacteria, yeast or fungi and obtained in this way.
The endoxyloglucan transferase can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions, and the like.
In addition to its usefulness in laundry detergent and fabric care compositions, endoxyloglucan transferase can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp.
When endoxyloglucan transferase is present in the compositions of the present invention, it is desirable that the xyloglucan concentration in the compositions is in the range of from about 0.01% to 30% by weight of the total composition, more preferably, 1% to 10% by weight of the total composition. Furthermore, the compositions of the present invention can have xyloglucan polymers of high molecular weight added to the compositions to obtain the benefits discussed above.
Accordingly, when the transferase is a xyloglucan transferase, such as endoxyloglucan transferase, the xyloglucan transferase preferably exhibits greater transferase activity than hydrolase (hydrolytic) activity and/or the xyloglucan transferase preferably exhibits strict donor specificity for high molecular weight xyloglucan polymers and does not act on lower molecular weight xyloglucan oligomers, more preferably the xyloglucan transferase exhibits strict donor specificity for xyloglucan polymers having molecular weights of at least 10,000.
Yet another enzyme that is of particular interest is cyclomaltodextrin glucanotransferase ("CGT-ase") (EC 2.4.1.19), which is commercially available from Amano and Novo Nordisk A S.
Covalent linking of carbohydrates, oligo and polysaccharides to cotton surfaces, such as fabrics, with a transferase delivers benefits such as anti-wrinkling, color 11
maintenance, dye fixation and soil repulsion. Covalent linkage of glucose units to the cellulose surface versus a physical absorption of polymers, which are produced by the transferase in situ (or others), make the observed benefits durable.
Cyclomaltodextrin glucanotransferase is a transferase that exhibits several different actions on starch. It produces from starch α, β, and γ cyclodextrins, hydrolyzes starch and cross links starch. In these types of reactions, α sugars are both donor and acceptor for the transferase reaction. Up to now, it was not clear if these transferase enzymes could covalently link sugar units to cotton.
Surprisingly, it has been found that cyclomaltodextrin glucanotransferase can covalently link glucose units from α-cyclodextrine to the cotton surfaces of fabrics at the non-reducing end of the cellulose polymers. Accordingly, cyclomaltodextrin glucanotransferase has the ability to make the benefits discussed above more durable.
As discussed above, it is known that covalently linking cellulose polymers with cross-linking agents delivers benefits to fabrics, such as anti-wrinkle benefits, but anti- wrinkle benefits can also be obtained by a physical absorption of polymers on the cotton surface. This physical absorption of polymers on the cotton surface can now be made more durable since one of the polymer units is covalently linked to the cotton surface by the action of cyclomaltodextrin glucanotransferase. Since these more durable benefits are produced enzymatically, the covalent linking occurs at a much lower temperature, thus, much lower temperatures as compared to conventional wash cycles are feasible in the wash cycle. In addition, conventional cross-linking chemicals (some of them are potentially toxic), which are used in the textile industry, are not applicable at the lower temperatures in the wash cycle.
Other benefits, such as dye fixation and improved soil release, are obtained through the covalent incorporation of cationic or anionic glucose units to the cotton surface.
Accordingly, the use of cyclomaltodextrin glucanotransferase in laundry detergent and fabric care compositions provides improved anti-wrinkle, shape retention, anti- shrinkage, dye fixation, soil repulsion and tensile strength benefits for fabrics.
The cyclomaltodextrin glucanotransferase can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions, and the like.
In addition to its usefulness in laundry detergent and fabric care compositions, cyclomaltodextrin glucanotransferase can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp.
When cyclomaltodextrin glucanotransferase is present in the compositions of the present invention, it is desirable that the starch concentration in the compositions is in the 12
range of from about 0.01% to 30% by weight of the total composition, more preferably, 1% to 10% by weight of the total composition. Furthermore, the compositions of the present invention can have cyclodextrins or types of starch and sucrose added to the compositions to obtain the benefits discussed above.
Still yet another group of enzymes that is of particular interest is glucansucrases, of which dextransucrase (EC 2.4.1.5), a glycosyltransferase, is one example. Other glucansucrases that are suitable for use in the compositions described herein include, but are not limited to, various dextransucrases and alternansucrases. Alternatively, levansucrase, which is commercially available from Genencor, can be used.
Dextransucrase enzymes can be obtained from any suitable source known in the art, and are used in conjunction with appropriate substrates (sucrose +/-maltose). Dextransucrase catalyzes transfer reactions of glycosyl residues from one polysaccharide to another. As a result of dextransucrase reactions, high molecular weight dextrans are produced on fabric surfaces. In dextrans, glucose residues are linked by 1-6-α linkages. Modification of cotton fiber with carbohydrates, oligo and polysaccharides, delivers benefits such as anti-wrinkling, color maintenance, dye fixation and soil repulsion. The durability of these benefits may require covalent linkage of the oligosaccharides.
It has been found that dextransucrase can be bound to oligosaccharides to cellulose polymers in cotton. As a result of this binding via the transfer reactions catalyzed by the dextransucrase provided improved fabric appearance benefits i.e., improved anti-wrinkling, shape retention, anti-shrinkage, dye fixation, soil repulsion and tensile strength benefits. When the reaction products are bound (may or may not be a covalent linkage) to cotton, they modify the cotton surface and fibrils, which in turn delivers the fabric care benefits discussed above. Dextransucrase with sucrose also provided improved whiteness benefits (dyes from other color garments are not deposited on white fabrics). The dextransucrase/sucrose combination forms high molecular weight dextran (and smaller oligomers when other saccharides such as maltose, cellobiose, etc., are present).
Furthermore, it has been found that the deposition efficiency of reaction products on the fabrics is high, and that the reaction products are all not washed off in the following wash cycle.
The glucansucrases can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions, and the like.
In addition to their usefulness in laundry detergent and fabric care compositions, glucansucrases can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp. 13
When glucansucrase is present in the compositions of the present invention, it is desirable that the substrate (typically sucrose or other disaccharides) concentration in the compositions is in the range of from about 0.01% to 30% by weight of the total composition, more preferably, 1% to 10% by weight of the total composition. Furthermore, the compositions of the present invention can have smaller polysaccharides such as sucrose, maltose, maltdextrins, cellosaccharides, and types of starch added to the compositions to obtain the benefits discussed above.
These transferases are preferably incorporated into the compositions in accordance with the invention at a level of from 0.0001% to 10%, more preferably from 0.0005% to 5 %, most preferred from 0.001% to 1% pure enzyme by weight of the total composition.
The fabric care and/or cleaning benefits can be obtained by the laundry and/or fabric care compositions of the present invention in presence or absence of the corresponding natural substrate. In general, the first part of the enzyme name indicates the substrate for the enzyme reaction and the second part is the acceptor to which the group is transferred. The substrate of the transferase enzyme can be the fabric itself, stains and/or soils, added in any treatment including pre- or post-treatment from the textile industry and/or from any washing and/or fabric care process, and/or added together with the transferase-containing composition.
Examples of substrates for some of the transferases listed above are : S-adenosyl- L-methionine, 5,10-methylenetetrahydrofolate or formiminotetra-hydrofolate (hydroxymethyl or formyl group transfer to glycine), formaldehyde, acetyl Co A, methyl- a,w-diamine, palmityl Co A, geranoyl di phosphate.
In particular, the substrate for the aminoacyl transferases is an amino containing compound such as an amino acid, a di tri polypeptide and/or a protein.
Among the glycosyltransferases, though the transferring group is a glycosyl residue, the specifics of the substrate for each enzyme is derived from the first part of the name. Especially for the glycosyltransferases, the natural substrate could be any alpha- glucosyl saccharide chosen from amylaceous substances in a dimer, oligomer and/or polymer. The examples are preferably different forms of starch (gelatinized, liquefied, solubilized), partial starch hydrolysate, more preferably malto-oligosaccharides, and most preferably maltose. Of interest are also substituted starch/sugar substrates, containing methylation and carboxylation substitution. Alternatively, the following substrates could be used for the mentioned glycosyltransferases: dextrins, sucrose, raffinose, fructosyl polymers, UDP glucose, xyloglucan, GDP glucose, arylamine, UDP galacturonate, ADP glucose, indole-3 -acetate, a-D-glucans, UDP-xylan. 14
The transferase-substrates are preferably incorporated into the compositions in accordance with the invention at a level of from 0.01% to 30%, more preferably from 0.1% to 20%, most preferably from 1% to 10% by weight of the total composition.
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, baropbilic, 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 and/or chelant stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular fabric conditioning and/or 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. Surfactants

The compositions of the invention may contain a lime soap peptiser compound, which has a lime soap dispersing power (LSDP), as defined hereinafter of no more than 8, preferably no more than 7, most preferably no more than 6. The lime soap peptiser compound is preferably present at a level from 0% to 20% by weight.
A numerical measure of the effectiveness of a lime soap peptiser is given by the lime soap dispersant power (LSDP) which is determined using the lime soap dispersant test as described in an article by H.C. Borghetty and CA. Bergman, J. Am. Oil. Chem. Soc, volume 27, pages 88-90, (1950). This lime soap dispersion test method is widely used by practitioners in this art field being referred to, for example, in the following 22
review articles; W.N. Linfield, Surfactant science Series, Volume 7, page 3; W.N. Linfield, Tenside surf, det, volume 27, pages 159-163, (1990); and M.K. Nagarajan, 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 CaCθ3 (Ca:Mg=3:2) equivalent hardness.
Surfactants having good lime soap peptiser capability will include certain amine oxides, betaines, sulfobetaines, alkyl ethoxysulfates and ethoxylated alcohols.

The laundry detergent and/or fabric care compositions herein may also optionally contain one or more preservatives. The function of the preservatives is to prevent organisms/micro-organisms from breeding and growing on the fabrics treated with the laundry detergent and/or fabric care compositions herein. In the absence of such preservatives, organisms/micro-organisms could grow on the fabrics treated with the laundry detergent and/or fabric care compositions herein because a significant amount of carbohydrates/sugar could remain on the fabrics after treatment.
Sanitization of fabrics can be achieved by the compositions of the present invention containing antimicrobial materials, e.g., antibacterial halogenated compounds, quaternary compounds, and phenolic compounds.
Suitable preservatives for use with the present invention include, but are not limited to, the following. 28
It is preferable to use a broad spectrum preservative, e.g., one that is effective on both bacteria (both gram positive and gram negative) and fungi. A limited spectrum preservative, e.g., one that is only effective on a single group of microorganisms, e.g., fungi, can be used in combination with a broad spectrum preservative or other limited spectrum preservatives with complimentary and/or supplementary activity. A mixture of broad spectrum preservatives can also be used. In some cases where a specific group of microbial contaminants is problematic (such as Gram negatives), aminocarboxylate chelators may be used alone or as potentiators in conjunction with other preservatives. These chelators which include, e.g., ethylenediaminetetraacetic acid (EDTA), hydroxyethylenediaminetriacetic acid, diethylenetriaminepentaacetic acid, and other aminocarboxylate chelators, and mixtures thereof, and their salts, and mixtures thereof, can increase preservative effectiveness against Gram-negative bacteria, especially Pseudomonas species.
Antimicrobial preservatives useful in the present invention include biocidal compounds, i.e., substances that kill microorganisms, or biostatic compounds, i.e., substances that inhibit and/or regulate the growth of microorganisms. (1) Organic Sulfur Compounds

It 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 92870018.6 filed January 31, 1992.
Alkoxylated polycarboxylates such as those prepared from polyacrylates are useful herein to provide additional grease removal performance.

The side-chains are ester-linked to the polyacrylate "backbone" to provide a "comb" polymer type structure. The molecular weight can vary, but is typically in the range of about 2000 to about 50,000. Such alkoxylated polycarboxylates can comprise from about 0.05% to about 10%, by weight, of the compositions herein. Detergent Composition Form
The laundry detergent and/or fabric care 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.
The compositions of the invention may for example, be formulated as hand and machine laundry detergent compositions including laundry additive compositions and compositions suitable for use in the soaking and/or pre-treatment of stained fabrics, rinse added fabric softener compositions. Pre-or post treatment of fabric include gel, spray and liquid fabric care compositions. A rinse cycle with or without the presence of softening agents is also contemplated.
When formulated as compositions suitable for use in a laundry machine washing method, the compositions of the invention preferably contain both a surfactant and a 35
builder compound and additionally one or more detergent components preferably selected from organic polymeric compounds, bleaching agents, additional enzymes, suds suppressors, dispersants, lime-soap dispersants, soil suspension and anti-redeposition agents and corrosion inhibitors. Laundry compositions can also contain softening agents, as additional detergent components.
The compositions of the invention can also be used as detergent additive products. Such additive products are intended to supplement or boost the performance of conventional detergent compositions.
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.
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.
A preferred filler salt is sodium sulphate.
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.
The compositions of the present invention can be incorporated into a spray dispenser that can create an article of manufacture that can facilitate the cleaning and/or fabric care of fabric. Compositions containing from 1 ppm to 50 ppm of pure transferase enzyme by weight of total composition and 0.01% to 20% of its corresponding substrate by weight of total composition, are preferably sprayed onto the fabrics and therefore typically packaged in a spray dispenser.
The spray dispenser can be any of the manually activated means for producing a spray of liquid droplets as is known in the art, e.g. trigger-type, pump-type, non-aerosol 36
self-pressurized, and aerosol-type spray means. It is preferred that at least about 70%, more preferably, at least about 80%, most preferably at least about 90% of the droplets have a particle size of smaller than about 200 microns.
The spray dispenser can be an aerosol dispenser. Said aerosol dispenser comprises a container which can be constructed of any of the conventional materials employed in fabricating aerosol containers. The dispenser must be capable of withstanding internal pressure in the range of from about 20 to about 110 p.s.i.g., more preferably from about 20 to about 70 p.s.i.g. The one important requirement concerning the dispenser is that it be provided with a valve member which will permit the wrinkle reducing composition contained in the dispenser to be dispensed in the form of a spray of very fine, or finely divided, particles or droplets. The aerosol dispenser utilizes a pressurized sealed container from which the wrinkle reducing composition is dispensed through a special actuator/valve assembly under pressure. The aerosol dispenser is pressurized by incorporating therein a gaseous component generally known as a propellant. Common aerosol propellants, e.g., gaseous hydrocarbons such as isobutane, and mixed halogenated hydrocarbons, are not preferred. Halogenated hydrocarbon propellants such as chlorofluoro hydrocarbons have been alleged to contribute to environmental problems. Preferred propellants are compressed air, nitrogen, inert gases, carbon dioxide, etc. A more complete description of commercially available aerosol spray dispensers appears in U.S. Pat. Nos.: 3,436,772, Stebbins, issued Apr.8, 1969; and 3,600,325, Kaufman et al., issued Aug. 17, 1971; both of said references are incorporated herein by reference.
Preferably the spray dispenser can be a self-pressurized non-aerosol container having a convoluted liner and an elastomeric sleeve. Said self-pressurized dispenser comprises a liner/sleeve assembly containing a thin, flexible radially expandable convoluted plastic liner of from about 0.010 to about 0.020 inch thick, inside an essentially cylindrical elastomeric sleeve. The liner/sleeve is capable of holding a substantial quantity of odor-absorbing fluid product and of causing said product to be dispensed. A more complete description of self-pressurized spray dispensers can be found in U.S. Pat. Nos.: 5,111,971, Winer, issued May 12, 1992; and 5,232,126, Winer, issued Aug. 3, 1993; both of said references are herein incorporated by reference. Another type of aerosol spray dispenser is one wherein a barrier separates the wrinkle reducing composition from the propellant (preferably compressed air or nitrogen), as is disclosed in U.S. Pat. No. 4,260,110, issued Apr. 7, 1981, incorporated herein by reference. Such a dispenser is available from EP Spray Systems, East Hanover, N.J.
More preferably, the spray dispenser is a non-aerosol, manually activated, pump- spray dispenser. Said pump-spray dispenser comprises a container and a pump 37
mechanism which securely screws or snaps onto the container. The container comprises a vessel for containing the wrinkle reducing composition to be dispensed.
The pump mechanism comprises a pump chamber of substantially fixed, volume, having an opening at the inner end thereof. Within the pump chamber is located a pump stem having a piston on the end thereof disposed for reciprocal motion in the pump chamber. The pump stem has a passageway there through with a dispensing outlet at the outer end of the passageway and an axial inlet port located inwardly thereof.
The container and the pump mechanism can be constructed of any conventional material employed in fabricating pump-spray dispensers, including, but not limited to: polyethylene; polypropylene, polyethlyleneterephthalate; blends of polyethylene, vinyl acetate, and rubber elastomer. Other materials can include stainless steel. A more complete disclosure of commercially available dispensing devices appears in: U.S. Pat. Nos.: 4,895,279, Schultz, issued Jan. 23, 1990; 4,735,347, Schultz et al., issued Apr. 5, 1988; and 4,274,560, Carter, issued Jun. 23, 1981; all of said references are herein incorporated by reference.
Most preferably, the spray dispenser is a manually activated trigger-spray dispenser. Said trigger-spray dispenser comprises a container and a trigger both of which can be constructed of any of the conventional material employed in fabricating trigger- spray dispensers, including, but not limited to : polyethylene, polypropylene, polyacetal, polycarbonate, polyethylene-terephthalate , polyvinyl chloride, polystyrene, blends of polyethylene, vinyl acetate, and rubber elastomer. Other materials can include stainless steel and glass. The trigger-spray dispenser does not incorporate a propellant gas. The trigger-spray dispenser herein is typically one which acts upon a discrete amount of the wrinkle reducing composition itself, typically by means of a piston or a collapsing bellows that displaces the composition through a nozzle to create a spray of thin liquid. Said trigger-spray dispenser typically comprises a pump chamber having either a piston or bellows which is movable through a limited stroke response to the trigger for varying the volume of said pump chamber. This pump chamber or bellows chamber collects and holds the product for dispensing. The trigger spray dispenser typically has an outlet check valve for blocking communication and flow of fluid through the nozzle and is responsive to the pressure inside the chamber. For the piston type trigger sprayers, as the trigger is compressed, it acts on the fluid in the chamber and the spring, increasing the pressure on the fluid. For the bellows spray dispenser, as the bellows is compressed, the pressure increases on the fluid. The increase in fluid pressure in either trigger-spray dispenser acts to open the top outlet check valve. The top valve allows the product to be 38
forced through the swirl chamber and out the nozzle to form a discharge pattern. An adjustable nozzle cap can be used to vary the pattern of the fluid dispensed.
For the piston spray dispenser, as the trigger is released, the spring acts on the piston to return to its original position. For the bellows spray dispenser, the bellows acts as the spring to return to its original position. This action causes a vacuum in the chamber. The responding fluid acts to close the outlet valve while opening the inlet valve drawing product up the chamber from the reservoir.
A more complete disclosure of commercially available dispensing devices appears in U.S. Pat. Nos.: 4,082,223, Nozawa, issued Apr. 4, 1978; 4,161,288, McKinney, issued Jul. 7, 1985; 4,434,917, Saito et al., issued Mar. 6, 1984; and 4,819,835, Tasaki, issued Apr. 11, 1989; 5,303,867, Peterson, issued Apr. 19, 1994; all of said references are incorporated herein by reference.
