Background of the invention Performance of a detergent product 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.

Therefore, detergent compositions include nowadays a complex combination of active ingredients which fulfill certain specific needs. In particular, current detergent formulations generally include surfactants and detergent enzymes providing cleaning and fabric care benefits.

Removal of stains stemming from plants, wood, mould-clay based soils, muddy soils, and fruits is one of today's toughest cleaning task ; especially with the trend toward low wash temperatures. These stains typically contain complex mixtures

of fibrous material based mainly on carbohydrates and their derivatives : fibres and cell wall components. Plant based soils are additionally accompanied with amylose, sugars and their derivatives. Food soils are often difficult to remove effectively from a soiled substrate. Highly coloured or"dried-on"soils derived from fruit and/or vegetable juices are particularly challenging to remove. Specific examples of such soils would include orange juice, tomato juice, banana, mango or broccoli soils. Indeed, pectin polymers are important constituents of plant cell walls. Pectin is a hetero-polysaccharide with a backbone composed of alternating homogalacturonan (smooth regions) and rhamnogalacturonan (hairy regions).

The smooth regions are linear polymers of 1, 4-linked alpha-D-galacturonic acid.

The galacturonic acid residues can be methyl-esterified on the carboxyl group to a varying degree, usually in a non-random fashion with blocks of polygalacturonic acid being completely methyl-esterified. The substrates on which pectin containing stains are commonly found can be fabrics, dishware or hard surfaces.

In addition, highly coloured or'dried-on'soils derived for example, from fruit and/or vegetables are also particularly challenging soils to remove. These coloured stains contain highly coloured compounds based on carotenoid compounds such as a-, (3- and y-carotene and lycopene and xanthophyls (zeaxanthin or capsanthin), or porphyrins such as chlorophyll and 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, pomegranate, red cabbage, red beets and also flowers. Carotenoids soils are derived from carrots and tomatoes and in any processed products containing these components as well as certain tropical fruits and saffron.

In particular in the dishwashing context, these coloured food soils may be removed from soiled articles into the wash solution, and then may be redeposited from the wash solution onto other articles in the wash or onto the interior of the dishwashing machine. The problem is particularly noticeable when the wash load includes articles soiled by foods naturally containing significant levels of coloured dyestuff molecules, including for example tomato sauce and curry.

The Applicant has found that plastic articles in the wash, and especially areas of the interior of the dishwashing machine which are made of plastic material, are particularly susceptible to the staining/discoloration of the dishware by coloured food soils. Said soils can interact with the surface of such plastic substrates producing staining which can be very difficult to remove.

A number of the Applicant's co-pending European Patent Applications have proposed solutions to solve the problem of coloured food dyestuff deposition in a machine dishwashing method. For example, EP 692 947 provides an efficient dye transfer inhibiting composition for use in a machine dishwashing method.

The composition comprises an enzymatic system capable of generating hydrogen peroxide in combination with certain metallo catalysts. EP 740 521 describes the use of diacyl and tetraacyl peroxide bleaching species for inhibiting the transfer of bleachable food soils and enhancing their removal from plastic substrates.

Furthermore, 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 due in part to their interaction with the pectin components in the primary cell walls of cotton fibers comprising cotton containing fabrics, and often residues build up on such fabric leading to dinginess and yellowing. Moreover, body fluid stains, such as blood and menstrual fluids, are often difficult to remove effectively from a soiled item, especially when the stains have been aged. Everyday body soils are also found on sanitary and kitchen surfaces such as bathtubs, toilet bowls and dishware.

Bleaching compositions for the bleaching of such plant-, dirt based stains, highly coloured stains and soils and body soils, have been extensively described in the art. Suitable bleaching agents are usually percompounds which liberate hydrogen peroxide in aqueous solution, such as peroxyhydrates, perborate, percarbonate, perpyrophosphate, persilicate, urea peroxide and the like. It is know that the use of such percompounds can be improved by the use of organic bleach activators or peroxyacid precursors. Such bleaching compositions are known to be effective in the removal of all sorts of stains. More recently, products containing bleach catalysts, particularly manganese bleach catalysts have become of interest.

In addition, oxygen bleaching agents have become increasingly popular in recent years in household and personal care products to facilitate stain and soi ! removal. Bleaches are particularly desirable for their stain-removing, dingy fabric cleanup, whitening and sanitization properties. Oxygen bleaching agents have found particular acceptance in laundry products such as detergents, in automatic dishwashing products and in hard surface cleansers. Oxygen bleaching agents, however, are somewhat limited in their effectiveness. Some frequently encountered disadvantages include colour damage on fabrics and damage to laundry appliances, specifically rubber hoses these appliances may contain. In addition, oxygen bleaching agents tend to be extremely temperature rate dependent. Thus, the colder the solution in which they are employed, the less effective the bleaching action. Temperatures in excess of 60°C are typically required for effectiveness of an oxygen bleaching agent in solution.

Attempts have been made to develop a bleach system which will be effective in lower temperature water conditions. U. S. Patent No. 5, 360, 568 to Madison et al., U. S. Patent No. 5, 360, 569 to Madison et al., and U. S. Patent No. 5, 370, 826 to Madison et al., all relate to positively charged quaternary imine salts as catalysts for peroxygen compounds to transfer active oxygen and thus are said to increase the activity of peroxygen compounds over a range of water temperatures, including lower temperatures. However, these positively charged quaternary imine salts are not completely satisfactory in laundry bleaching applications. In particular, the positively charged quaternary imine salts disclosed in these references, when combined with peroxygen compounds, cause an unacceptable level of colour damage on fabrics.

Accordingly, the need remains for a detergent compositions providing effective bleaching, especially of plant-, dirt based stains, highly coloured stains and soils and body soils. Such need is even more accute in lower water temperatures and while providing improved colour-safety profiles and/or preventing the staining /discoloration of dishware by highly coloured components. These needs are met by the detergent compositions of the present invention comprising a pectate lyase enzyme and a bleach system selected from : a combination of a bleach booster and a peroxygen source, a metal bleach catalyst and/or a diacyl peroxide.

It has been surprisingly found that such selected bleach systems can maximise the pectate lyase enzyme cleaning efficiency. Further it has been surprisingly found that detergent compositions comprising a pectate lyase and a such selected bleach system, provide superior cleaning due to the synergistic effect of the selected bleach system providing cleaning, stain removal and in a laundry context whiteness maintenance, and the pectate lyase degrading the pectin components of such soil and/or, in a laundry context, the pectin component of the fabrics that can bind such soils. These selected bleach systems-enzyme mixed systems deliver an outstanding cleaning effect, especially on food coloured stains and body soils. Moreover, when formulated as a laundry and/or fabric care composition, the compositions of the present invention provide synergistic whiteness maintenance.

Without wishing to be bound by theory, it is believed that the natural pectins found in many common fruit and vegetable based soils as well as the primary wall of cotton fibers attract and hold soil residues, particularly highly colored soil components. Removal of the pectin component with pectate lyase exposes these color bodies to the bleach system. It is believed that the synergistic effect is due to these bleach systems decolourizing the colour components of tough to remove food stains and body soils and the pectate lyase degrading the pectin components of such soil and/or in a laundry context. the pectin components of the fabrics that can bind or otherwise interact with such soils, making said soils difficult to remove.

In particular, it has been surprisingly found that the detergent compositions of the present invention comprising a diacyl peroxide, provide effective stain removal, especially on highly coloured stains and soils, especially on plasticware, and further prevent the staining/discoloration of the dishware by highly coloured components. Furthermore, it has been surprisingly found that the combination of a pectate lyase with the bleach booster as the selected bleach system, enhances cleaning by improving the overall efficiency of the bleach system, especially at low wash temperatures. The addition of a bleach booster enables the oxygen- based bleaching system to more thoroughly bleach these exposed color bodies at low wash temperatures resulting in both improved stain removal and enhanced whiteness.

Pectin degrading enzymes are known to provide soil/stain removal benefits when used in washing and cleaning operations, specifically to provide the removal of a broad range of plant and fruit based stains and enhance the body soil cleaning profile of the detergent compositions. By pectin degrading enzyme it is meant herein any enzyme which acts to break down pectin substances and pectin related substances. Pectin degrading enzymes can be classified according to their preferential substrate, highly methyl-esterified pectin or low methyl-esterified pectin and polygalacturonic acid (pectate), and their reaction mechanism, beta- elimination or hydrolysis. Pectin degrading enzymes can be mainly endo-acting, cutting the polymer at random sites within the chain to give a mixture of oligomers, or they may be exo-acting, attacking from one end of the polymer and producing monomers or dimers. Several pectinase activities acting on the smooth regions of pectin are included in the classification of enzymes provided by the Enzyme Nomenclature (1992) such as pectate lyase (EC 4. 2. 2. 2), pectin lyase (EC 4. 2. 2. 10), polygalacturonase (EC 3. 2. 1. 15), exo-poiygaiacturonase (EC 3. 2. 1. 67), exo-polygalacturonate lyase (EC 4. 2. 2. 9) and exo-poly-alpha- galacturonosidase (EC 3. 2. 1. 82). The pectin degrading enzymes are natural mixtures of the above mentioned enzymatic activities.

Each type of pectin degrading enzyme has a unique profile of substrate specificity, activity and stability under different hardness, pH, temperature, surfactant and other detergent ingredient matrix conditions. Pectin degrading enzymes are specifically directed to degrade pectin substances and in particular plant cell walls. In particular, pectate lyase enzymes are directed to the cleavage of a-D- (1, 4) glycosidic bonds in poly-D-galacturonans by the mechanism of- elimination. These pectate lyase enzymes further help as well the removal of mixed stains soils comprising pectin substances and other components.

However, soils stains which are not sensitive to pectate lyases such as non- pectin carbohydrates, lipids, proteins and their derivatives may block the accessibility of the pectin substances to the enzymes and necessitate a further strong detergent ingredient.

The use of pectin degrading enzymes in detergent has already been recognised in the art. The use of pectin enzyme is also recognised for the cleaning of contact lenses (US 4, 710, 313-J60196724). Enzymes having a pectinase activity are described in DE 36 35 427 to increase the capacity of the detergent for removing

inorganic dirt, e. g. sludge, from laundry without damaging the fibres and without discoloration to allow the use of zeolites and polycarbonate builders which have a lower capacity for dispersing inorganic materials than the phosphates. Benefits for the use of pectin enzymes in detergent formulations, particularly those designed for use in laundry, dishwashing and household cleaning operations have been recognised in W095/25790. JP 60226599 describes detergent compositions comprising conventional detergent actives and a cellulase and hydrolase such as hemicellulase, pectinase, amylase or protease. The combination of cellulase and hydrolase is said to give a good washing effect on inorganic fouling together with enzymatic activity. W095/09909 describes an enzyme preparation comprising modified enzymes selected from the group of amylase, lipase, oxidoreductase, pectinase or hemicellulase ; the modified enzymes having an improved performance due to an alkaline pl and/or increased surface activity obtained by chemical modification or amino acid substitution.

Modified pectin and/or pectolytic and/or hemi-cellulolytic and/or lipolytic enzymes are applied advantageously in the papermaking industry and modified amylase and/or lipase in laundry and dishwashing.

However, the synergistic combination of a pectate lyase and a selected bleach system selected from a combination of a bleach booster and a peroxygen source, a metal catalyst and/or a diacyl peroxide in a bleaching composition, for superior cleaning performance in a detergent composition, has never been previously recognised.

Summary of the invention The present invention relates to laundry, dishwashing or hard surface cleaner detergent compositions comprising a pectate lyase and a bleach system selected from : a combination of a bleach booster and a peroxygen source, a metal bleach catalys and or a diacyl peroxide.

These compositions provide superior cleaning performance, especially on plant-, dirt-based stains, highly coloured food soiis/stains and body soils. Such laundry detergent compositions also provide superior whiteness maintenance.

Furthermore, these compositions comprising a colour-safe booster, provide superior cleaning performance in lower water temperatures while providing improved colour-safety profiles. In addition, these compositions comprising diacyl peroxide, provide effective highly coloured stains and soils removal, especially on plasticware, and further prevent the staining/discoloration of the dishware by highly coloured components.

Detailed description of the invention The detergent compositions of the present invention comprise as essentiai elements a pectate lyase enzyme and a bleach system selected from : a combination of a bleach booster and a peroxygen source, a metal bleach catalyst and/or a diacyl peroxide.

Each type of pectin degrading enzyme has a unique profile of substrate specificity, activity and stability under different hardness, pH, temperature, surfactant and other detergent ingredient matrix conditions. Pectin degrading enzymes are specifically directed to degrade pectin substances and in particular

plant cell walls. In particular, pectate lyase is a pectin degrading enzyme which splits the a-1, 4, glucoside bond of polygalacturonic acids found in pectin substances, to create a double bond between C4 and C5. Pectate lyase enzymes further help the removal of mixed stains soils comprising pectin substances and other components. However, soils stains which are not sensitive to pectate lyases such as non-pectin carbohydrates, lipids, proteins and their derivatives or highly coloured materials associated with the pectins, may block the accessibility of the pectin substances to the enzyme and necessitate a further strong detergent ingredient.

It has been surprisingly found that the selected bleach of the present invention can maximise the pectate lyase cleaning efficiency. Such selected bleach systems are known to provide superior cleaning and stain removal of highly coloured stains, and in a laundry and/or fabric care context, whiteness maintenance and especially greasy/oily stain removal. Without wishing to be bound by theory, it is believed that the pectate lyase degrades the pectin component of soils and stains that serves to bind colour bodies and chromophores. Such enzymatic degradation of the pectin components exposes these colour bodies and chromophores to the bleach system, allowing them to be effectively removed. It has been found that such combinations lead to performance synergy in soil and stain cleaning, especially on coloured food stains/soils and body soils.

In particular, it is well known in the art that cleaning performance decreases with decreasing temperatures. This is especially true for the removal of pectin-based stains/soils and the performance of oxygen bleaching systems. Not wishing to be bound by theory it is believed that pectate lyase helps to improve overall cleaning at low temperatures by catalyzing the hydrolysis of the pectin found in many soils/stains, and in a laundry context, in the residual primary wall of cotton fibers, that can trap and hold color bodies onto surfaces. Hydrolysis of the pectin allows easier removal by the rest of the detergent ingredients. Improved removal of the pectin component of highly colored food stains as well as the pectin from cotton fibers exposes soil chromophores to the oxygen bleaching system in the detergent formulation. Bleach booster enhances performance of the oxygen bleach system at low temperatures. The combination of a pectate lyase with a bleach booster in a detergent formulation containing an oxygen bleaching

system, provides an effective means of removing high colored food soils from dishware and fabric surfaces and, in a iaundry context, effective removal of body soils from fabric surfaces.

The Pectate Lyase enzyme An essential element of the detergent composition of the present invention is a pectate lyase enzyme.

Pectate lyase is classified within the classification of enzymes provided by the Enzyme Nomenclature (1992) as EC 4. 2. 2. 2. Said enzyme is known to split the a-1, 4, glucoside bond of galacturonic acid found in pectin substances, creating a double bond between C4 and C5 and is substantially free for other pectin degrading activities, i. e having less than 25%, preferably less than 15%, more preferably less than 5% by weight of the enzyme compound of other pectin degrading enzyme activities.

Pectate lyases have been cloned from different bacterial genera such as Erwinia, <BR> <BR> <BR> Pseudomonas, Kiebsiella, Streptomyces, Penicillium, Bacteroides, Thermomonospora, Fusarium, Aspergillus and Xanthomonas. Also from Bacillus subtilis (Nasser et al. (1993) FEBS 335 : 319-326) and Bacillus sp. YA-14 (Kim et al. (1994) Biosci. Biotech. Biochem. 58 : 947-949) cloning of a pectate lyase has been described. Purification of pectate lyases with maximum activity in the pH range of 8-10 produced by Bacillus pumilus (Dave and Vaughn (1971) J.

Bacteriol. 108 : 166-174), B. polymyxa (Nagel and Vaughn (1961) Arch. Biochem.

24 : 1164-1172) has been reported. WO 98/45393 discloses detergent compositions containing protopectinase with remarkable detergency against muddy soils.

Further suitable pectate lyases for use in the present invention are the protopectinases having an optimum reaction pH of 7. 0 or higher when polygalacturonic acid is used as a substrate such as described in W098/45393 and the pectic acid lyase having the amino acid sequence SEQ no 1 of EP 870

More preferred pectate lyases for the purpose of the present invention are those having optimum activity at pH's >7. 0 and derived from Streptomyces fradiae, Streptomyces nitrosporeus, Erwinia carotovora, Bacillus spheroides, Thermomonospora fusca, Pseudomonas solanacearum, Bacteroides thetaiotaomicron, Fusarium solani, Xanthomonas campestris, Bacillus agaradhaerens, and/or Bacillus licheniformis.

Most preferred pectate lyase for the purpose of the present invention is the Pectate lyase from Bacillus agaradhaerens, NCIMB 40482 or DSM 8721.

The pectate lyase is incorporated into the detergent compositions of the present invention preferably at a level of from 0. 0001% to 2%, more preferably from 0. 0005% to 0. 1%, most preferred from 0. 001% to 0. 02% pure enzyme by weight of the composition.

The pectate lyase of the invention, in addition to the enzyme core comprising the catalytically domain, may also contain a cellulose binding domain (CBD), the cellulose binding domain and enzyme core (the catalytically active domain) of the enzyme being operably linked. The cellulose binding domain (CBD) may exist as an integrai part of the encoded enzyme, or a CBD from another origin may be introduced into the enzyme thus creating an enzyme hybrid. In this context, the term"cellulose-binding domain"is intended to be understood as defined by Peter Tomme et al."Cellulose-Binding Domains : Classification and Properties"in "Enzymatic Degradation of Insoluble Carbohydrates", John N. Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618, 1996. This definition classifies more than 120 cellulose-binding domains into 10 families (I-X), and demonstrates that CBDs are found in various enzymes such as cellulases, xylanases, mannanases, arabinofuranosidases, acetyl esterases and chitinases.

CBDs have also been found in algae, e. g. the red alga Porphyra purpurea as a non-hydrolytic polysaccharide-binding protein, see Tomme et al., op. cit.

However, most of the CBDs are from cellulases and xylanases, CBDs are found at the N and C termini of proteins or are internal. Enzyme hybrids are known in the art, see e. g. WO 90/00609 and WO 95/16782, and may be prepared by transforming into a host cell a DNA construct comprising at least a fragment of DNA encoding the cellulose-binding domain ligated, with or without a linker, to a DNA sequence encoding the pectate lyase enzyme and growing the host cell to express the fused gene. Enzyme hybrids may be described by the following formula : CBD-MR-X wherein CBD is the N-terminal or the C-terminal region of an amino acid sequence corresponding to at least the cellulose binding domain ; MR is the middle region (the linker), and may be a bond, or a short linking group preferably of from about 2 to about 100 carbon atoms, more preferably of from 2 to 40 carbon atoms ; or is preferably from about 2 to about 100 amino acids, more preferably of from 2 to 40 amino acids ; and X is an N-terminal or C-terminal region of the pectate lyase of the invention.

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, haiophilic, 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 metal binding sites to increase chelant stability.

In the instance, DAP is included in the detergent compositions of the present invention in the form of a particulate, such particulate comprises, by weight of said particulate, from 1-80% of a water-insoluble diacyl peroxide and from 0. 01% to 95% stabilising additive in which the diacyl peroxide does not dissolve.

Examples of suitable additives are inorganic salts, transition metal chelants, antioxidants, binding agents, coatings agents and/or mixtures thereof.

The term"Diacyl peroxide does not dissolve"is defined herein to mean the diacyl peroxide does not dissolve in the stabilising additive (s) under particulate processing conditions and/or detergent storage conditions. The Term"Water insoluble"is defined herein to mean limited water solubility, i. e. less than 1%, preferably less than 0. 5%, dissolves in water. The term"stabilising additive"is defined herein to mean a compound or compound (s) the prevents the diacyl peroxide from decomposing with other ingredients, especially components in which the diacyl peroxide is soluble in and with which the diacyl peroxide will reacted while stored in the product.

Said particle provide storage stability and protect the diacyl peroxide from interacting with other ingredients and decomposing in the composition over time.

The stabilizing additive in the particle is by weight of the particle from about 0. 1% to about 95%, preferably from about 10% to about 95%, more preferably from about 40% to about 95% stabilizing additive.

Preferably, the stabilizing additive is not miscible with other components of the composition at temperatures at or below 100°F, preferably 120°F. In a particularly preferred embodiment the stabilizing agent would be soluble in the wash solution.

The inorganic salt, useful as a stabilizing additive include but are not limited to alkali metal sulfates, citric acid, and boric acid, and their salts, alkali metal carbonates, bicarbonates and silicates and mixtures thereof. Preferred

inorganic salts are sodium sulfate and citric acid. which, because they are non- alkaline, prevent alkaline hydrolysis in product.

Binding agents and coating agents include but are not limited to certain water soluble polymers in which the diacyl peroxide does not dissolve, ethoxylated C16-C20 alcohols with sufficient ethoxylate groups to prevent dissolution of the diacyl peroxide, aliphatic fatty acids, aliphatic fatty alcohols, maltodextrins, dextrin, starch, gelatin, polyethylene glycols with melting points above 100°F, polyvinyl alcohol, and sorbitol. The polymers include polyacrylates with an average molecular weight of from about 1, 000 to about 10, 000, and acrylate/maleate or acrylate/fumarate copolymers with an average molecular weight of from about 2, 000 to about 80, 000 and a ratio of acrylate to maleate or fumarate segments of from about 30 : 1 to about 1 : 2. Examples of such copolymers based on a mixture of unsaturated mono-and dicarboxylate monomers are disclosed in European Patent Application No. 66, 915, published December 15, 1982, incorporated herein by reference. Other suitable copolymers are modified polyacrylate copolymers as disclosed in U. S. Patents 4, 530, 766, and 5, 084, 535, both incorporated herein by reference.

Transition metal chelats which can be employed are selected from the group consisting of polyacetate and polycarboxylate builders such as the sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylenediamine tetraacetic acid, ethylenediamine disuccinic acid (especially the S, S-form), nitriiotriacetic acid, tartrate monosuccinic acid, tartrate disuccinic acid, oxydisuccinic acid, carboxymethyloxysuccinic acid, mellitic acid, sodium benzene polycarboxylate salts ; nitrilotris (methylenephosphonic acid) diethylenetrinitrilopentakis (methylenephosphonic acid), 1-hydroxyethylidene-1, 1- diphosphonic acid, other phosphonates chelats (e. g. Dequest line of products from Monsanto), ethylene-N, N'-bis (o-hydroxyphenylglycine), dipicolinic acid and mixtures thereof.

Antioxidants (radical trap, radical scavenger or free radical inhibitor) can also be suitable stabilizing additives. These compounds slow down or stop a reaction even though present in small amounts. In the present invention it is believed the antioxidant would trap or scavenge the radical formed due to thermal decomposition of the peroxide bond. This would prevent the radical from further reacting or propagating the formation of another radical (self-accelerated decomposition). Since this material would be used in small amounts in the particle, it most likely would not hurt overall performance of the detergent

composition. Suitable antioxidants include but are not limited to citric acid, phosphoric acid, BHT, BHA, a-tocopherol, Irganox series C (Ciba Giegy), Tenox series (Kodax) and mixtures thereof..

It can be noted that of the above listed stabilizing additives can also provide other benefits in a detergent product (i. e. pH control, carbonate/silicate dispersion) as well as serve as the stabilizing additive. These ingredients therefore may aiso be added separately from the particulate. For example, agglomerated forms of the present invention may employ aqueous solutions of the polyacrylates discussed herein above as liquid binders for making the agglomerate.

The diacyl peroxide particles formed preferably have a mean particle size from about 400pm to about 1000jim, more preferably from about 600|um to about 800um with less than 1 % of the diacyl peroxide particle population being greater than 1180m (Tyler 14 mesh) and less than 1% less than or equal to 212X1m (Tyler 65 mesh).

Typically, diacyl peroxide is added to the detergent compositions of the present invention at a level of from 0. 01 % to 20% by weight of the composition, preferably 0. 5% to 10%, more preferably 0. 2% to 3%. When the diacyl peroxide is incorporated into a particulate, the compositions of the present invention comprise by weight of the composition from 0. 1% to 30%, preferably from 1 % to 15%, more preferably from 1. 5% to 10% of diacyl peroxide particle.

The bleach catalyst is typically used in a catalytically effective amount in the compositions and processes herein. By"catalytically effective amounts meant an amount which is sufficient, under whatever comparative test conditions are employed, to enhance bleaching and removal of the stain or stains of interest from the target substrate. The test conditions will vary, depending on the type of washing appliance used and the habits of the user. Some users elect to use very hot water ; others use warm or even cold water in laundering operations. Of course, the catalytic performance of the bleach catatyst will be affected by such considerations, and the levels of bleach catalyst used in fully-formulated detergent and bleach compositions can be appropriately adjusted. As a practical matter, and not by way of limitation, the compositions and processes herein can be adjusted to provide on the order of at least one part per ten million of the active bleach catalyst species in the aqueous washing liquor, and will preferably provide from about 1 ppm to about 200 ppm of the catalyst species in the wash liquor.

For certain perhydrate salts however, the preferred executions of such granular compositions utilise a coated form of the material which provides better storage stability for the perhydrate salt in the granular product.

A suitable coating material providing in product stability comprises mixed salt of a water soluble alkali metal sulphate and carbonate. Such coatings together with coating processes have previously been described in GB-1, 466, 799, granted to Interox on 9th March 1977.

L may be selected from any of the leaving groups described hereinbefore for the analogues having R1 as an aryl or alkaryl group. Amide substituted bleach activator compounds of this type are described in EP-A-0170386.

The L group must be sufficiently reactive for the reaction to occur within the optimum time frame (e. g., a wash cycle). However, if L is too reactive, this activator will be difficult to stabilize for use in a bleaching composition. These characteristics are generally parallele by the pKa of the conjugate acid of the leaving group, although exceptions to this convention are known. Ordinarily, leaving groups that exhibit such behaviour are those in which their conjugate acid has a pKa in the range of from 4 to 13, preferably from 6 to 11 and most preferably from 8 to 11.

Preferably, M is an alkali metal, ammonium or substituted ammonium cation, with sodium and potassium being most preferred, and X is a halide, hydroxide, methylsulfate or acetate anion. It should be noted that bleach activators with a leaving group that does not contain a solubilizing groups should be well dispersed in the bleaching solution in order to assist in their dissolution.

Organic peroxyacids

The compositions may contain as components of the bleaching system organic peroxyacids, typically at a level of from 2% to 30% by weight, more preferably from 5% to 20% by weight of the bleaching composition. When the bleaching compositions are comprised in a detergent composition in accordance with the present invention, the organic peroxyacid is preferably present at a level of from 1% to 15% by weight and more preferably from 1% to 10% by weight of the detergent composition.

A preferred class of organic peroxyacid compounds are the amide substituted compounds of the following general formulae : wherein R1 is an alkyl, aryl or alkaryl group with from 1 to 14 carbon atoms, R2 is an alkylene, arylene, and alkarylene group containing from 1 to 14 carbon atoms, and R5 is H or an alkyl, aryl, or alkaryl group containing 1 to 10 carbon atoms.

Also suitable is the nonanoyl-oxybenzene-sulfonate (NOBS, described in US 4, 412, 934). 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 USSN 08/136, 626, PCT/US95/07823, W095/27772.

W095/27773, W095/27774 and W095/27775.

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 91202655. 6 filed October 9, 1991.

Detergent components The detergent compositions of the invention will preferably comprise further additional detergent components. The precise nature of these additional component, 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.

The detergent compositions according to the invention can be liquid, paste, gels, bars, tablets, spray, foam, powder or granular. Granular compositions can also be in"compact"form and the liquid compositions can also be in a"concentrated" form. Tablet compositions can be in single phase or multiple phase form.

It has been surprisingly found that the cleaning benefits of pectate lyase enzymes can be optimised and maximised with a t ; me controlled release technology. In particular, the time controlled technology is a tablet wherein the pectate lyase is separated from the inhibiting/deactivating other detergent ingredients in a different product phase having a different solubility in the wash. It has been surprisingly found that optimal performance efficiency of the pectate lyase enzyme can be achieved when said enzyme is incorporated into a tablet and such system delivers significant soil and stain cleaning benefits. It has further been found that such time controlled release technology allows a broader range of Pectate Lyases to be used, including those that show a high degree of instability in standard detergent matrices. Indeed, the pectate lyase and buffer materials can preferably be incorporated into the rapid dissolving portion of the tablet. Without wishing to be bound by theory, it is believed that the pectate lyase

is released earlier than the inhibiting/deactivating other detergent ingredients and that optimum pectate lyase activity is obtained at the beginning of the wash under buffered conditions, allowing the formulation in detergent of pectate iyases in the full range of available pectate lyases.

Suitable tablets are detergent tablets which are not only sufficiently robust to withstand handling and transportation, but also at least a portion of which dissolves rapidly in the wash water providing rapid delivery of the pectate lyase enzyme. It is preferred that at least one phase of the tablet dissolves in the wash water within the first ten minutes, preferably five minutes, more preferably four minutes of the wash cycle of an automatic dishwashing or laundry washing machine. Preferably the washing machine is either an automatic dishwashing or laundry washing machine. The time within which the multi-phase tablet or a phase thereof or a detergent active component dissolves is determined according to DIN 44990 using a dishwashing machine available from Bosch on the normal 65°C washing program with water hardness at 18°H using a minimum of six replicates or a sufficient number to ensure reproducibility.

In a first embodiment, the present invention relates to laundry detergent compositions comprising a pectate lyase and a selected bleach system (Examples 1-16). In a second embodiment, the present invention relates to dishwashing detergent compositions comprising a pectate lyase, a peroxygen source, and a bleach booster (Examples 17-27).

The bleaching composition of the present invention may be advantageously employed in laundry applications, hard surface cleaning, automatic dishwashing applications, as well as cosmetic applications such as dentures, teeth, hair and skin. However, due to the unique advantages of both increased effectiveness in lower temperature solutions and the superior color-safety profile, the bleach boosters of the present invention are ideally suited for laundry applications such as the bleaching of fabrics through the use of bleach containing detergents or laundry bleach additives. Furthermore, the bleach boosters of the present invention may be employed in both granular and liquid compositions.

The compositions of the invention may for example, be formulated as hand 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 and compositions for use in general household hard surface cleaning operations. When formulated as compositions for use in manual dishwashing methods the compositions of the invention preferably contain a surfactant and preferably other detergent compounds selected from organic polymeric compounds, suds enhancing agents, group 11 metal ions, solvents, hydrotropes and additional enzymes.

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 builder compound and additionally one or more detergent components preferably selected from organic polymeric compounds, bleaching agents, additional enzymes suds suppressors, dispersants, time-soap dispersants, soil suspension and anti-redeposition agents and corrosion inhibitors. Laundry compositions can also contain softening agents, as additional detergent components. Such compositions containing a pectate lyase, a peroxygen source and a bleach booster can provide fabric cleaning, stain removal, and color appearance when formulated as laundry detergent compositions.

When formulated as compositions suitable for use in a machine dish wash method, the compositions of the invention preferably contain a low foaming nonionic surfactant, a builder system, and one or more 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.

Conventional detergent enzymes The detergent compositions can in addition to the pectate lyase enzyme further comprise one or more enzymes which provide cleaning performance, fabric care and/or sanitisation benefits. Preferably the detergent compositions of the present invention will further comprise a pectin lyase.

Said enzymes include enzymes selected from cellulases, hemicellulases, peroxidases, proteases, gluco-amylases, amylases, xyianases, lipases, phospholipases, esterases, cutinases, other pectinases, keratanases, reductases, oxidases, phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, ß-glucanases, arabinosidases, hyaluronidase, chondroitinase, laccase or mixtures thereof. A preferred combination is a detergent composition having cocktail of conventional applicable enzymes like protease, amylase, lipase, cutinase and/or cellulase in conjunction with one or more plant cell wall degrading enzymes.

Each type of pectin degrading enzyme has a unique profile of substrate specificity, activity and stability under different hardness, pH, temperature, surfactant and other detergent ingredient matrix conditions. Pectin degrading enzymes are specifically directed to degrade pectin substances and in particular plant cell walls. In particular, pectate lyase enzymes are specifically directed to pectic acid chains of plant cell walls such as low methoxy pectins while pectin lyase is more specifically directed towards esterified pectin chains such as high methoxy pectins. Moreover, it has been found that pectate lyases are metal and especially calcium sensitive, whereas pectin lyases do not require metals for stabilisation and optimum enzymatic activity, It has been surprisingly found that a wide range of range of substrate specificity and a high flexibility toward a variety of wash conditions can be achieved with combining further the pectate lyase of the present invention with a pectin lyase. This results in synergistic cleaning and especially plant-based soil/stains and body soil removal.

Pectin lyase enzyme is classified under the EC classification EC 4. 2. 2. 10, is preferably substantially free of other pectic enzymes, and acts on the pectic acids

to bring about non-hydrolytic cleavage of alpha-1-4 glycosidic linkages to give oligosaccharides with terminal 4-deoxy-6-a-D-galacto-enuronosyl groups. The pectin lyase of the present invention is substantially free of other pectic enzymes.

By"substantially free of other pectic enzymes", it is meant pectin lyase enzyme- containing compositions which contain less than 25% of pectic enzymes which are not pectin lyase enzymes, preferably less than 15%, more preferably less than 5%. The enzymatic activity can be measured according to the"Assay of trans-eliminase activities toward pectin and pectic acid"described by K.

Horikoshi in Agr. Biol. Chem, Vol 36 (2), 286.

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.

Other amylases known for use in detergent compositions include both a-and p-amy ! ases. a- Amylases are known in the art and include those disclosed in US Pat. no.

5, 003, 257 ; EP 252, 666 ; WO/91/00353 ; FR 2, 676, 456 ; EP 285, 123 ; EP 525, 610 ; EP 368, 341 ; and British Patent specification no. 1, 296, 839 (Novo). Other suitable amylases are stability-enhanced amylases described in W094/18314, published August 18, 1994 and W096/05295, Genencor, published February 22, 1996 and amylase variants having additional modification in the immediate parent available from Novo Nordisk A/S, disclosed in WO 95/10603, published April 95. Also suitable are amylases described in EP 277 216, W095/26397 and W096/23873 (all by Novo Nordisk).

Examples of commercial a-amylases products are Purafect Ox Am from Genencor and Termamyl, Ban@ Fungamylg and Duramyl), all available from Novo Nordisk A/S Denmark. W095/26397 describes other suitable amylases : a-

amylases characterised by having a specific activity at feast 25% higher than the specific activity of Termamyl at a temperature range of 25°C to 55°C and at a pH value in the range of 8 to 10, measured by the Phadebas a-amylase activity assay. Suitable are variants of the above enzymes, described in W096/23873 (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 W095/35382.

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.

The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungai 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. Special attention must be paid to the cellulases as most of the cellulases have separate binding domains (CBD). Properties of such enzymes can be altered by modifications in these domains.

Said enzymes are normally incorporated in the detergent composition at levels from 0. 0001 % to 2% of pure 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).

Other suitable detergent ingredients that can be added are enzyme oxidation scavengers which are described in Co-pending European Patent application 92870018. 6 filed on January 31, 1992. Examples of such enzyme oxidation scavengers are ethoxylated tetraethylene polyamines.

A range of enzyme materials and means for their incorporation into synthetic detergent compositions is also disclosed in WO 9307263 A and WO 9307260 A to Genencor International, WO 8908694 A to Novo, and U.

Fabric softening agents can also be incorporated into detergent 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-BO 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.

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.

Cheating Agents The detergent compositions herein may also optionally contain one or more iron and/or manganese cheating agents. Such cheating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic cheating 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.

Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilo-

triacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines. alkaii metal, ammonium, and substituted ammonium salts therein and mixtures therein.

Amino phosphonates are also suitable for use as cheating 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. Preferably, these amino phosphonates do not contain alkyl or alkenyl groups with more than about 6 carbon atoms.

Polyfunctionally-substituted aromatic cheating 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.

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.

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.

If utilized, these cheating agents will generally comprise from about 0. 1% to about 15% by weight of the detergent compositions herein. More preferably, if utilized, the cheating agents will comprise from about 0. 1% to about 3. 0% by weight of such compositions.

Suds suppressor Another optional ingredient is a suds suppressor, exemplified by silicones, and silica-silicone mixtures. Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. These materials can be incorporated as particulates in which the suds suppressor is advantageously releasably incorporated in a water-soluble or water-dispersible, substantially non-surface-active detergent impermeable

carrier. Alternatively the suds suppressor can be dissolved or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.

A preferred silicone suds controlling agent is disclosed in Bartollota et al. U. S.

Patent 3 933 672. Other particularly useful suds suppressors are the self- emulsifying silicone suds suppressors, described in German Patent Application DTOS 2 646 126 published April 28, 1977. An example of such a compound is DC-544, commercially available from Dow Corning, which is a siloxane-glycol copolymer. Especially preferred suds controlling agent are the suds suppressor system comprising a mixture of silicone oils and 2-alkyl-alcanols.

The detergent active composition of phase 1 is prepared by admixing the granular and liquid components and is then passed into the die of a conventional rotary press. The press includes a punch suitably shaped for forming a mould. The cross-section of the die is approximately 30x38 mm. The composition is then subjected to a compression force of 940 kg/cm2 and the punch is then elevated exposing the first phase of the table'containing the mould in its upper surface. The detergent active composition of phase 2 is prepared in similar manner and is passed into the die. The particulate active composition is then subjected to a compression force of 170 kg/cm2, the punch is elevated, and the multi-phase tablet ejected from the tablet press. The resulting tablets dissolve or disintegrate in a washing machine as described above within 12 minutes, phase 2 of the tablets dissolving within 5 minutes. The tablets display improved strength, especially on long-term storage, together with excellent dissolution characteristics.

The tablet composition III was prepared as follows : The compressed portion is prepared by delivering the composition of aciive detergent components to a punch cavity of a modified rotary tablet press and compressing the composition at a pressure of 940kg/cm2. The modified tablet press provides tablet wherein the compressed portion has a mould. For the purposes of Example t ! t, the non- compressed portion is in particulate form. The non-compressed portion is accurately delivered to the mould of the compressed portion using a nozzle feeder. The non-compressed portion is adhered to the compressed portion by coating the non-compressed portion with a coating layer which contacts the compressed portion.
