DETERGENT COMPOSITIONS COMPRISING A CYCLODEXTRIN GLUCANOTRANSFERASE ENZYME
s This application has been divided out of Canadian Patent Application Serial No. 2,412,371 filed internationally June 30, 2000 as PCT/US/18119, published internationally as W002/02725.
Field of the Invention The present invention relates to detergent compositions comprising a cyclodextrin transferase enzyme and a detergent ingredient selected from a nonionic surfactant, a protease and/or a bleaching agent.
Background of the invention Performance of a detergent product is judged by a number of factors, including the ability to remove soils. Therefore, detergent components such as surfactants, 2o bleaching agents and enzymes, have been incorporated in detergents. One of such specific example is the use of proteases, lipases, arrrylases and/or cellulases.
In particular, amylase enzymes have long been recognised in detergent compositions to provide the removal of starchy food residues or starchy films from dishware or hard surfaces or to provide cleaning performance on starchy soils as well as other soils typically encountered in laundry and dishwashing applications. Indeed, ~ starchy materials such as amylose and amylopectin, constitute one of the major components of the soils /stains encountered in laundry, dishwashing or hard surfaces cleaning operations. Moreover, the textile industry uses starchy materials in their textile finishing processes.
Therefore, amylase enzymes have been since a long time incorporated into the detergent products for the removal of starch-containing stains. However, it has been surprisingly found that such commonly used , detergent amylases could not hydrolyse retrograded starch or raw starch.

As studied in J. A. Radley "Starch and its Derivatives" Fourth Edition Chapman and Hall Ltd p194-201; retrogradation is a term given to the changes which occur spontaneously in a starch paste, or gel on ageing. !t arises from the inherent tendency of starch molecules to bind to one another and which leads to an s increase in crystallinity. Solutions of low concentration become increasingly cloudy due to the progressive association of starch molecules into larger particles. Spontaneous precipitation takes place and the precipitated starch appears to be reverting to its original condition of cold-water insolubility.
Pastes of higher concentration on cooling set to a gel, which on ageing becomes ~o steadily firmer due to the increasing association of the starch molecules.
This arises because of the strong tendency for hydrogen bond formation between hydroxyl groups on adjacent starch molecules.
The changes taking place during retrogradation are of considerable importance ~s in the industrial uses of starch. It is believed to be an important~factor in the staling of bread and in the textural changes of other starch-containing foods, e.g.
canned soups, peas, meat preparations, etc. Starch and retrograded starch are also found in the textile, paper and adhesives industries. indeed, fabrics are sized with starch in the textile process. Depending on the sizing process, 2o retrograded starch can be fom~ed on the fabrics and might riot be removed in the ulterior desizing processes. Moreover, the majority of the stains/soils found on fabrics, dishware and other hard surfaces, especially those found in the kitchen, contain starch which upon ageing in for e.g., the laundry basket or dishwashing machine will retrograde to such associated starchy network. Hence, such zs retrograded starch containing materials are found later onto the fabric, dishware and/or other hard surfaces to be cleaned. Such retrograded starch shows an increased resistance~to hydrolysis by amylolytic enzymes, is only slightly soluble at ordinary temperatures and redispersed only with difficulty, especially if the retrograded starch has dried first and it further demonstrates a progressive so increase in gel firmness. Indeed, it has been found that retrograded starch forms very stable structures and only melts at very high temperature such as 150°C for amylose, 60°C for amylopectin or 120°C for the complex amylose-lipid. The level and timing of retrogradation depends upon the starch type: it can vary from 10%
to 90% of th'e starch content. It has been found that current detergent amylases 35 have very little to no effect on retrograded starch.

!n addition, a substantial part of starch material remains indeed under the raw form even when processed within the food or textile industries. In particular, it has been found that food stains such as rice, spaghettis, potatoes, com, cereals, etc. retrieved on fabric, dishware and other hard surfaces contain a substantial s amount of raw starch.
Furthermore, it has been surprisingly found that such retrograded or raw starch remaining on the surfaces, entraps further dirt, and when found on a fabric surface, leads to a dingy appearance of the surface to be cleaned.
~o As can be seen from the above, there is a need to formulate detergent products which address the removal of such raw or retrograded starch containing soils/stains. Accordingly, the above objective has been met by formulating a detergent composition comprising a cyclodextrin transferase enzyme and a 15 detergent ingredient selected from a nonionic surfactant, a protease and/or a bleaching agent.
Indeed, it has been surprisingly found that the combination of a nonionic surfactant and a cyclodextrin glucanotransferase within a detergent composition, 2o provides a very effective cleaning of starch containing stains and soils.
Indeed, it has been found cyclodextrin glucanotransferase have a transferase activity as well as an endo-, exo- hydrolytic activity on starch, that can be very useful in a cleaning -applications. Moreover, such of starch containing stains and soils comprise many lipids components as well. Without wishing to be bound by theory 2s it is believed that the nonionic surfactant remove the lipids contained in the starch containing stains and soils and thereby facilitate the degradation of starch by the cyclodextrin glucanotransferase. In addition it is believed that the nonionic surfactant keeps the degraded starch in solution and prevents its redeposition onto the surface to be cleaned. It has been further surprisingly found that 3o nonionic surfactant prevents the retrogradation of starch and therefore is very efficient if used with the cyclodextrin transferase in a pre-treatment step.
Similarly, such of starch containing stains and soils comprise many proteins components as well. Without wishing to be bound by theory, it is believed that the protease enzyme hydrolyses the proteins contained in such complex stains and 35 thereby induces the synergistic removal of such stains/soils with the cyclodextrin giucanotransferase. in addition, such hydrolysed proteins/starch containing stainslsoils have a lower molecular weight in the wash solution and this results in less redeposition of such hydrolysed stains/soils on the surface to be cleaned.
Finally, it has been found that bleaching agents oxidise the starch containing stains and soils. Without wishing to be bound by theory it is believed that the s oxidising action of the bleaching agent renders the starch more soluble and therefore easier to be synergistically removed by the cyclodextrin glucanotransferase and the bleaching agent. It results as well in less redeposition on the surface to be cleaned.
~o Furthermore, it has been surprisingly found that the combination of a nonionic surfactant andlor protease, and a cyclodextrin giucanotransferase provides synergistic malodour control. It is believed that the main origin for malodour derives from greasy material such as those entrapped within complex soils/stains. Without wishing to be bound by theory it is believed that the nonionic ~s surfactant remove the lipids contained in the starch containing stains and soils.
Similarly, the combination with a protease would increase the starch removal.
This facilitates the degradation of starch by the cyclodextrin glucanotransferase.
Hence, there is more starch available to form cyciodextrin from the enzymatic activity of the cyclodextrin glucanotransferase. Cyclodextrin are known to 2o encompass a hydrophobic cavity that can entrap hydrophobic molecules and thereby remove odorous material. The combined action of the nonionic surfactant and/or protease, and the cyclodextrin glucanotransferase results in more cyclodextrin produced and more entrapped odorous material removed and therefore in better malodour control. In addition, it has been found that the 25 oxidising action of the bleaching agent has a sanitisation effect in preventing the growth of micro-organism on the surtace to be cleaned and thereby the formation of malodour.
Cyclodextrin glucanotransferase enzymes find application in processes for the 3o manufacture of cyclodextrins for various industrial applications, particularly in the food, cosmetic, chemical, agrochemical and pharmaceutical industries.
Cyclodextrin glucanotransferases may also be used in a process for the manufacture of linear oligosaccharides, in particular linear oligosaccharides of 2 to 12 glucose units. Cyclodextrin glucanotransferases are also used for in situ 35 generation of cyclodextrins, especially for methods of producing baked products, in methods for stabilizing chemical products during their manufacture, and in detergent compositions. Certain cyclodextrins are known to improve the quality of baked products. Cyclodextrins have an inclusion ability useful for stabilization, sofubilization, etc. Thus cyclodextrins can make oxidizing and photolytic substances stable, volatile substances non-volatile, poorly-soluble substances soluble, and odoriferous substances odorless, etc, and thus are useful to encapsulate perfumes, vitamins, dyes, pharmaceuticals, pesticides and fungicides.
Cyclodextrins are also capable of binding lipophilic substances such as cholesterol, to remove them from egg yolk, butter, etc. Cyclodextrins also find utilization in products and processes relating to plastics and rubber, where they have been used for different purposes in plastic laminates, films, membranes, etc. Also cyclodextrins have been used for the manufacture of biodegradable plastics.
EP 802 259 describes cyclodextrin transferases for the production of gamma-cyclodextrin. GB 169 902 discloses a polypeptide possessing cyclomaltodextrin glucanotransferase activity. JP07109488 describes detergent compositions 15 comprising a cyclodextrin transferase for high detergency against starch and deodorising effect. JP07107971 describes a specific cyclodextrin glucanotransferase from Bacillus, with improved stability towards alkali.
W096/33267 and W099/15633 are directed to specific novel cyclomaltodextrin glucanotransferase variants.
However, the synergistic combined use of a cyclodextrin transferase with a detergent ingredient specifically selected from a nonionic surfactant, a protease and/or a bleaching agent, for the synergistic removal of starch-containing stains-soils and malodour control in a detergent composition, has never been 2s previously recognised.
Sumr~,ar~of the invention The present invention relates to detergent compositions, including laundry, dishwashing, and/or hard surface cleaner compositions, comprising a cyclodextrin glucanotransferase and a protease. Such compositions provide excellent removal of 3o starch-containing stains and soils and malodour control; and when formulated as laundry compositions, excellent whiteness maintenance and cleaning of dingy materials.
The parent application is specifically directed to detergent compositions comprising s5 cyciodextrin glucanotransferase and a nonionic surtactant. A further divisional application is specifically directed to detergent compositions comprising cyclodextrin glucanotransferase and a bleaching agent.

Detailed descrilption of the inyention Cyclodextrin glucanotransferase The first element of the present invention is a cyclomaltodextrin glucanotransferase (E.C. 2.4.1.19), also designated cyclodextrin glucanotransferase or cyclodextrin glycosyltransferase, in the following termed CGTase, that catalyses the conversion of starch and similar substrates into cyclomaltodextrins via an intramolecular transglycosylation reaction, thereby forming cyclomaltodextrins, in the following termed cyclodextrins (or CD), of 1o various sizes. Commercially most important are cyclodextrins of 6, 7 and 8 glucose units, which are termed a-, b- and g-cyclodextrins, respectively. Commercially less important are cyclodextrins of 9, 10, and 11 glucose units, which are termed d-, e-, and z-cyclodextrins, respectively.
~5 Cyclodextrins are thus cyclic glucose oligomers with a hydrophobic internal cav'rly.
They are able to form inclusion complexes with many small hydrophobic molecules in aqueous solutions, resulting in changes in physical properties, e.g.
increased solubility and stability and decreased chemical reactivity and volatility.
Cyclodextrins find applications particularly in the food, cosmetic, chemical and 2o pharmaceutical industries.
Most CGT-ases have both starch-degrading activity and transglycosylation activity.
Although some CGTases produce mainly a-cyclodextrins and some CGTases produce mainly b-cyclodextrins, CGTases usually form a mixture of a-, b- and g-25 cyclodextrins. Selective precipitation steps with organic solvents may be used for the isolation of separate a-, b- and g-cyclodextrins. To avoid expensive and environmentally harmful procedures, the availability of CGTases capable of producing an increased ratio of one particular type of cyclodextrin is desirable.
3o CGTases from different bacterial sources, including CGTases obtained from Bacillus, Brevibacterium, Clostridium, Corynebacterium, Klebsiella, Micrococcus, Thermoanaerr~bacter and Themaoanaerobacterium have been described in the literature.

W099/43793 describes variants of CGT-ase that has the ability to form linear oligosaccharides v~rhen acting on starch. Such CGT-ase variant has a modification 1 o of at least one amino acid residue in a region corresponding to residues 40-43, 78-85, 136-139, 173-180, 189-195 or 259-268 of SEQ ID NO: 1 of W099143793. Each modification may be an insertion, a deletion or a substitution, of one or more amino acid residues in the region indicated. The modification of the parent CGT-ase is preferably such that the resulting modified amino acid or amino acid sequence more cloTsely resembles the corresponding amino acid or structural region in Novamyl. Thus, the modification may be an insertion of or a substitution with an amino acid present at the corresponding position of Novamyl, or a deletion of an amino acid not present at the corresponding position of Novamyl.
The CGT-ase variant may particularly comprise an insertion into a position 2o corresponding to the region D190-F194 of Novamyl (amino acid sequence shown in SEQ ID NO: 1 of W099/43793). The insertion may comprise 3-7 amino acids, particularly 4-6, e.g. 5 amino acids. The insertion may be DPAGF as found in Novamyl or an analogue thereof, e.g. with the first amino acid being negative, the last one being aromatic, and the ones in between being preferably P, A or G.
The variant may further comprise a substitution at the position corresponding to T189 of Novamyl with a neutral amino acid which is less bulky than F, Y or W. Other examples of insertions are DAGF, DPGF, DPF, DPAAGF, and DPAAGGF.
Modifications in the region 78-85 preferably include deletion of 2-5 amino acids, e.g. 3 or 4. Preferably, any aromatic amino acid in the region 83-85 should be 3o deleted or substituted with a non-aromatic.
Modifications in the region 259-268 preferably include deletion of 1-3 amino acid, e.g, two. The region may be modified so as to correspond to Novamyl The CGT-ase variant may comprise further modifications in other regions, e.g.
regions corresponding to amino acids 37-39, 44-45, 135, 140-145, 181-186, 269 273, or 377-383 of Novamyl.

Additional modifications of the amino acid sequence may be modeled on a second CGT-ase, i.e. an insertion of or substitution with an amino acid found at a given position in the second CGT ase, or they may be made close to the substrate (less than 8 A from the substrate, e.g. less than 5 A or less than 3 A) as described in W096/33267.
The following are some examples of variants based on a parent CGT-ase from Thermoanaerobacter (using B. circulars numbering). Similar variants may be made from other CGT-aces.

2o W099/43793 further describes Novamyl variants having the CGT-ase properties required within the present invention. Such Novamyl variant has as well the ability to form cyclodextrin when acting on starch and has a modification of at least one amino acid residue in the same regions described above for CGT-ase variants.
However, the modifications are preferably in the opposite direction, i.e. such that 2s the resulting modified amino acid or amino acid sequence more closely resembles the con-esponding amino acid or structural region of a CGT-ase. Thus, the modification may be an insertion of or a substitution with an amino acid present at the corresponding position of a CGT-ase, or a deletion of an amino acid not present at the corresponding position of a CGT-ase. Preferred modifications 3o include a deletion in the region 990-195, preferably the deletion (191-195) and/or a substitution of amino acid 188 and/or,189, preferably F188L and/or Y189Y.
Preferred CGT-ases for inclusion in the detergent compositions of the present invention are the following CGT-ases variants of W099/15633 described above in more details : CGTase variants showing an increased product specificity with respect to the production of a-cyclodextrin; CGTase variants showing an increased product specificity with respect to the production of ~3-cyclodextrin and those CGTase variants showing an increased product specificity with respect to the production of y-cyclodextrin. More preferred CGT-ases are CGTase variants of W099115633 showing an increased product specificity with respect to the production of ~i-cyclodextrin.
Such CGT-ase is generally comprised in the detergent compositions of the present invention at a level of from 0.0002% to 10%, preferably 0.001 % to 2%, more preferably 0.001 % to 1 % pure enzyme by weight of the total detergent s composition.
Commercially available CGT-ase is the enzyme product sold under the trademark Toruzyme by Novo Nordisk A/S, the enzyme product sold under the trademark CGT-ase from B. macerans by Amano and the enzyme product sold under the trademark EN301 from B.stearothermophilus by Hayashibara.
Preferred CGT-ase for specific applications are alkaline CGT-ase, i.e. enzymes having an enzymatic activity of at least 10%, preferably at least 25%, more preferably at least 40% of their maximum activity at a pH ranging from 7 to 12, ~s preferably 70.5. More preferred CGT-ase are enzymes having their maximum activity at a pH ranging from 7 to 12, preferably 10.5.
In another embodiment of the present invention, the detergent compositions of the present invention comprising a CGT-ase and detergent ingredient selected 2o from a nonionic surfactant, a protease and/or a bleach agent, might further one or more starch-binding domain. Such starch binding domain might be added in the detergent compositions of the present invention, as such, or might be part of a chimeric CGT-ase hybrid. Indeed, the CGT-ase of the present inventions preferably will have or will be added a Starch Binding Domain (SBD). In general 2s enzymes such as amylases, cellulases and xylanases have a modular structure consisting of a catalyst domain and at least one non-catalytic domain whose function is generally described as that of a polysaccharide-binding domain (PBD), starch-binding domain (SBD), cellulose-binding domain (CBD) and xylan-binding domain. The function of these binding domains is to bind selectively to so the substrate of the enzyme, and in particular, the primary function of SBD
is to bind to starch. It has been found surprisingly found that the detergent compositions of the present invention comprising one or more SBD and/or wherein the CGT-ase comprise such a SBD will provide a more effective starch-containing soils/stains removal. It has further been found that such enzymes can be formulated in a more cost-effective manner. Without wishing to be bound by theory, it is believed that such CGT-ase will be more effectively directed specifically to their substrate from the wash solutions and so have improved deposition onto the starch containing stains/soils for improved and/or new performance. Moreover, it is believed that the binding of the SBD will disrupt the surface of starch resulting in a higher hydrolytic rate.
1o Suitable SBD for use in the present invention are the SBDs comprised in the glucoamylase from Aspergillus niger ( Sigma) and in the (3-galactosidase from A.
awamori. The recovery and fusion of SBDs can be achieved as described in Ford, C. et al., J. Cell. Biochem. (Suppl.) 14D:30 (1990) and in Chen, L. et al., Abst. Annu. Meet. Am. Soc. Microbiol. 90:269 (1990).
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 2o be used. Nowadays, it is common practice to modify wild-type enzymes via protein l genetic engineering techniques in order to optimise their pertormance efficiency in the detergent 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 so 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 a5 and enforcing metal binding sites to increase chelant stability.

Nonionic surfactants A second element of the present invention can be a nonionic surfactant. As described below, preferred nonionic surfactants are selected from polyethylene oxide condensates of alkyl alcohols, amide oxide and polyethylene oxide condensates of alkyls acids and/or mixtures thereof.
The nonionic surfactants are generally comprised at a level of 0.05-30% by weight, preferably from 0.1-10% by weight of the total composition.
to As mentioned above, it has been surprisingly found that the detergent compositions of the present invention comprising a nonionic surfactant, provide synergistic removal of starch from fabrics, dishware and other hard surfaces.
Without wishing to be bound by theory, it is believed that the nonionic surfactant adsorbs onto the granular surface of the starch thereby disrupting the starch ~5 structure and influencing and preventing the retrogradation process of the starch.
Such disruption of the structure increases the . CGT-ase accessibility to its substrate. Moreover, nonionic surfactants can be used also in a pre-treatment process and therefore can reduce the retrogradation process of starch. Hence, the starch-containing stains / soils is more easily hydrolysed by the enzyme and zo a synergistic breakdown of the starch soil by the CGT-ase and the nonionic surfactant occurs.
The nonionic surtactant which can be used in the present invention may comprise essentially any alkoxylated nonionic surfactant. The ethoxylated and 25 propoxylated nonionic surfactants are preferred. Preferred alkoxylated surfactants can be selected from the classes of the nonionic condensates of alkyl phenols, nonionic ethoxylated alcohols, nonionic ethoxylated/propoxylated fatty alcohols, nonionic ethoxylate/propoxylate condensates with propylene glycol, and the nonionic ethoxylate condensation products with propylene oxidelethylene 3o diamine adducts. Highly preferred are nonionic alkoxylated alcohol surfactants, being the condensation products of aliphatic alcohols with from 1 to 125 moles of alkylene oxide, in particular about 50 or from 1 to 15 moles, preferably to 11 moles, particularly ethylene oxide and/or propylene oxide, are highly preferred nonionic surtactant comprised in the anhydrous component of the particles of the s5 invention. The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from 6 to 22 carbon atoms. Particularly preferred are the condensation products of alcohols having an alkyl group containing from 8 to 20 carbon atoms with from 2 to 9 moles and in particular 3, 5 or 7 moles, of ethylene oxide per mole of alcohol.
s The nonionic surfactant which can be used in the present invention may also comprise polyhydroxy fatty acid amides, in particular those having the structural formula R2CONR1Z wherein : R1 is H, C1_18, preferably C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, ethoxy, propoxy, or a mixture thereof, preferable C1-C4 alkyl, more preferably C1 or C2 alkyl, most preferably C1 alkyl (i.e., ~o methyl); and R2 is a C5-Cg1 hydrocarbyl, preferably straight-chain C5-C1g or C7-C1g alkyl or alkenyl, more preferably straight-chain Cg-C17 alkyl or alkenyl, most preferably straight-chain C11-C17 alkyl or alkenyl, or mixture thereof;

Z preferably will be derived from a reducing sugar in a reductive amination reaction; more preferably Z is a glycityl. A
preferred nonionic polyhydroxy fatty acid amide surfactant for use herein is a C12-C14 ~ a C15-C17 and/or C1 g-C1 g alkyl N-methyl glucamide.

1800, exhibiting cellulase activity; a preferred endoglucanase component has the amino acid sequence disclosed in PCT Patent Application No. WO 91/17243.
Also suitable cellulases are the EGI11 cellulases from Trichoderma longibrachiatum described in W094/21801, Genencor, published September 29, 1994. Especially suitable cellulases are the cellulases having color care benefits.
Examples of such cellulases are cellulases described in U.S.
patent No. 5,520,838 (Novo). CarezymeT"" and CelluzymeT"" (Novo Nordisk A/S) are especially useful. See also W091/17244 and 3o W091/21801. Other suitable cellulases for fabric care and/or cleaning properties are described in W096/34092, W096/17994 and W095/24471.
Said cellulases are normally incorporated in the detergent composition at levels from 0.0001 % to 2% of pure enzyme by weight of the detergent composition.
Peroxidase enzymes are used in combination with oxygen sources, e.g.
percarbonate, perborate, persulfate, hydrogen peroxide, etc and with a phenolic substrate as bleach enhancing molecule. 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 W089/099813, W089/09813 and in Canadian Patent application No. 2, 9 22,987, filed on October 28, 9 992 and EP 927,242 published July 7, 1999.
Also suitable is the lactase enzyme.
~o 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 W094/12621 ) and substitued syringates (C3-~5 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 pure enzyme by weight of the detergent 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, 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 detergent 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.

Example 11 The following laundry detergent compositions in the form of a tablet were prepared according to the present invention i) a detergent base powder of composition I was prepared as follows: a(I the particulate material of base composition I were mixed together in a mixing drum to form a homogenous particulate mixture. During this mixing, the spray-ons were carried out.
ii) Tablets were then made the following way: 50g of the matrix was introduced into a mould of circular shape with a diameter of 5.5 cm, and compressed to s give a tablet tensile strength (or diametrical fracture stress) of 10kPa.
iii) The tablets were then dipped in a bath comprising 90 parts of sebacic acid and 10 parts per weight of Nymcel-ZSB16T"' by Metsa Serla at 140 °C.
The time the tablet was dipped in the heated bath was adjusted to allow application of 4g of the bath mixture. The tablet was then left to cool at 1o ambient temperature of 25°C for 24 hours. The tensile strength of the coated tablet was increased to a tensile strength of 30 kPa.
