WO 00/42155 PCT/(JS00/00794 DETERGENT COMPOSITIONS COMPRISING A PECTATE LYASE AND A SPECIFIC SURFACTANT
SYSTEM

Field of the Invention The present invention relates to detergent compositions comprising a pectate lyase and specific surfactant selected from ~~. a~~ine oxide surfactant and/or a mid-chain branched anionic surfactant.
2o 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 fulfil certain specific needs. In particular, current detergent formulations generally include surfactants and detergent enzymes providing cleaning and fabric care benefits.
so 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 s5 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 ~o containing stains are commonly found can be fabrics, dishware or hard surfaces.
In addition, the complex nature of everyday "body" soils typically found on pillow cases, T-shirts, collars and socks, provides a continuous thorough cleaning challenge for detergents. These soils are difficult to remove completely due in 15 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 2o also found on sanitary and kitchen surfaces such as bathtubs, toilet bowls and dishware.
Amine oxide surfactants have been used since a very long time in the detergency industry and are known to provide good cleaning benefits, especially on grease 2s lipids soils. Anionic surfactants have been used since a very long time in the detergency industry. in recent years, mid-chain branched anionic surfactants were developed such as described in W097/39091 and W097138956 and in the co-pending US applications US97/06485, US97/06474, US97/06339, US97/06476 and US97/06338. These mid-chain branched anionic surfactants 3o are characterised by having the ability to couple with high hydrophobicity, a low temperature solubility and a high hardness tolerance. And therefore provide good cleaning properties, especially on greasy stains and body soils. These mid-chain branched are especially useful in cool or cold water laundry washing conditions, even in temperatures as low as 20°C-5°C. It has also been found that a 35 combination of two or more of these mid-chain branched surfactants can provide a surfactant mixture that is even higher in surfactancy and has better low temperature water solubility.
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 ~o 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 ~s 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-polygalacturonase (EC 3.2.1.67), exo-polygalacturonate lyase (EC 4.2.2.9) and exo-poly-alpha-2o gaiacturonosidase (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, z5 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 ~i-elimination. These pectate lyase enzymes further help as well the removal of 3o 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.

It has been surprisingly found that a unique surfactant system containing a surfactant selected from an amine oxide surfactant and/or a mid-chain branched anionic surfactant, can maximise the pectate lyase enzyme cleaning efficiency.
It has been surprisingly found that detergent compositions comprising a pectate lyase and such selected surfactant, provide superior cleaning due to the synergistic effect of the selected surfactant removing greasy stains and the pectate lyase degrading the pectin components of such soils and/or in a laundry context, the pectin components of the fabric that can bin or otherwise interact with such soils, making them difficult to remove. This surfactant - enzyme mixed ~o system delivers an outstanding cleaning effect, especially on these plant-based stains and body soils. in particular, it has been surprisingly found that such removal of greasy stains, is particularly effective with mid-chain branched anionic surfactant at low temperature.
~ 5 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. sludges, from laundry without damaging the fibres and without 2o 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 25 composition 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. W095I09909 describes an enzyme preparation comprising modified enzyme selected from the group of 3o amylase, lipase, oxidoreductase, pectinase or hemicellulase; the modified enzyme having an improved performance due to an alkaline pi andlor increased surface activity obtained by chemical modification or amino acid substitution.
Modified pectin and/or pectolytic and/or hemi-cellulolytic and for lipolytic enzymes are applied advantageously in the papermaking industry and modified amylase s5 andlor lipase in laundry and dishwashing.

In particular, Pectate lyases have been cloned from different bacterial genera such as Erwinia, Pseudomonas, Klebsiella, Streptomyces, Penicillium, Bacteroides, Thermomonospora, Fusarium, Aspergillus and Xanthomonas. Also from Bacillus subtilis (Nasser et al. (1993) FEES 335:319-326) and Bacillus sp.

Summary of the invention The present invention relates to detergent compositions, including laundry andlor 2s fabric care, dishwashing and hard surfaces compositions, comprising a pectate lyase and a surfactant selected from an amine oxide surfactant andlor mid-chain branched anionic surfactant. These compositions provide superior cleaning performance, especially on plant-based stains and body soils.
Detailed description of the invention The present invention relates to detergent compositions comprising a pectate lyase and a surfactant selected from an amine oxide surfactant andlor mid-chain branched anionic surfactant, for providing superior cleaning performance.

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,giucoside bond of polygaiacturonic acids found in pectin substances, to create a double bound between C4 and C5.
Pectate lyase enzymes further help the removal of mixed stains / soils ~o comprising pectin substances and other components. However, soils I 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 enzyme and necessitate a further strong detergent ingredient.
It has been -surprisingly found that a unique surfactant system comprising a surfactant selected from an amine oxide surfactant andlor mid-chain branched anionic surfactant, can maximise the pectate lyase cleaning efficiency. Such surfactants are known to provide superior cleaning, stain removal and in a laundry andlor fabric care context, whiteness maintenance and especially 2o greasyloily stain removal. Without wishing to be bound by theory, it is believed that the combination of an amine oxide surfactant andlor a mid-chain branched anionic surfactant with a pectate lyase enzyme, achieves high substrate specificity, high solution activity and high flexibility towards a variety of wash conditions and applications needs. It has been found that such combination 25 leads to performance synergy in soil and stain cleaning, especially on food stainslsoils and body soils.
Indeed and without wishing to be bound by theory, it is believed the synergistic cleaning benefits observed with the detergent compositions of the present so invention is the result of the selected surfactant of the present invention, promoting the removal of greasy soils bound to the fabric by pectins and that the pectate lyase hydrolysing the pectin network which entraps a variety of soils species. Furthermore and without wishing to be doubt by theory, it is believed that the amine oxide andlor mid-chain branched anionic surfactants provide 3s superior removal of hydrophobic soils such as body soils, mechanical and grease/oil, especially at low temperature, by emulsifying such soils and reducing WO 00/42155 PCT/US00/00'794 their melting points. The pectate lyase enzyme is believed to further aid the cleaning action by removing the pectin containing compounds found in a number of dirt, mud and plant-based soils as well as the natural pectin found on cotton fabric. The combination of improved hydrophobic soil removal with the removal of the pectin containing compounds of soils that can entrap other spoils materials is believed responsible for the synergistic, superior cleaning, whitening and stain removal observed with the detergent compositions of the present invention.

~ s 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 2o 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, Pseudomonas, Klebsiella, Streptomyces, Penicillium, Bacteroides, 2s Thermomonospora, Fusarium, Aspergillus and Xanthomonas. Also from Bacillus subfilis (Nasser et al. (1993) FEES 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.

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 s 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 ~o 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 integral 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 w - ~ -~sw 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 2o 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 2s at the N and C termini of proteins or are internal. Enzyme hybrids are known in the art, see e.g. WO 90100609 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 ao 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 35 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, halophilic, etc.). Purred or non-purified forms of these enzymes may be used. Nowadays, it is common practice to modify wild-type enzymes via ~ o 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, ~ 5 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 2o 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.

2,5-dimethylpentadecylsulfate having the formula:

2,6-dimethylpentadecylsulfate having the formula 2,7-dimethylpentadecylsulfate having the formula 2,8-dimethylpentadecylsulfate having the formula 2,9-dimethylpentadecylsulfate having the formula 2,10-dimethylpentadecylsulfate having the formula wherein M is preferably sodium.
The mid-chain branched encompasses in the present invention can be manufactured according to the process described in W097I38956. Such process prepares mid- to near mid-chain branched olefins (primarily, methyl branched at ~o or near the mid-chain region). Such materials are then used as the basic feedstock which provides the hydrophobic portion of branched-chain detersive surfactants.
The process herein is designed to provide branched reaction products which are primarily (85%, or greater) alpha-olefins, and which are then converted into ~ 5 hydrophobes in the Oxo-reaction sequence noted hereinafter. Preferably, such branched alpha-olefins contain frorri about 11 to about 18 (avg.) total carbon atoms and comprise a linear chain having an average length in the 10-18 region.
The branching is predominantly mono-methyl, but some di-methyl and some ethyl branching may occur. Advantageously, the present process results in little 20 (1%, or less) geminal branching, i.e., little, if any, "quaternary" carbon substitution. Moreover, little (less than about 20%) vicinal branching occurs.
Of course, some (ca. 20%) of the overall feedstock used in the subsequent Oxo-process may remain unbranched. Typically, and preferably from the standpoint of cleaning performance and biodegradability, the present process provides 25 alpha-olefins with: an average number of branches (longest chain basis) in the 0.4-2.5 range; of the branched material, there are essentially no branches on carbons 1, 2 or on the terminal (omega) carbon of the longest chain of the branched material.
Following the formation and purification of the branched-chain alpha-olefin, the 3o feedstock is subjected to an Oxo carbonylation process. In this Oxo-step, a catalyst (e.g., conventional cobalt carbonyl; see Kirk Othmer, below) which does not move the double bond from its initial position is used. This avoids the WO 00/42155 PCT/US00/00?94 formation of vinylidene intermediates (which ultimately yield less favorable surfactants) and allows the carbonylation to proceed at the #1 and #2 carbon atoms.
Deter4ent 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.
Ttre-detergent compositions according to the invention can be-liquid, paste, gels, ~ s 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 enzyme can be optimised and maximised with a time controlled release technology. In 2o 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 25 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 3o tablet. Without wishing to be bound by theory, it is believed that the pectate lyase is released earlier than the inhibiting I 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 lyases in the full range of available pectate lyases.

WO 00!42155 PCT/US00/00794 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 s 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 o 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.

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 fyase. 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 an 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.

By "substantially free of other pectic enzymes", it is meant pectin lyase enzyme-containing compositions which contain less than 25% of pectic enzymes which 2o 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.

Other amylases known for use in detergent compositions include both a- and p-amylases. a-Amylases are known in the art and include those disclosed in US Pat. no.
5,003,257; EP 252,666; WO/91100353; 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 ~o August 18, 1994 and W096105295, Genencor, published February 22, 1996 and amylase variants having additional modification in the immediate parent available from Novo Nordisk A/S, disclosed in WO 95110603, published April 95. Also suitable are amylases described in EP 277 216, W095/26397 and W096/23873 (all by Novo Nordisk).
~ s Examples of commercial a-amylases products are Purafect Ox Am~ from Genencor and Termamyl~, Ban~ ,Fungamyl~ and Duramyl~, all available from Novo Nordisk AlS Denmark. W095126397 describes other suitable amylases : a-amylases characterised by having a specific activity at least 25% higher than the specific activity of Termamyl~ at a temperature range of 25°C to 55°C and at a 2o 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.
2s 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.
3o 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 ss protein I 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 5 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 ceHulases have separate binding ~5 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 2o 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 25 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.

Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms ~5 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 20 liquid carrier and applied by spraying on to one or more of the other components.

Other useful polymeric materials are the polyethylene glycols, particularly those of molecular weight 1000-10000, more particularly 2000 to 8000 and most preferably about 4000. These are used at levels of from 0.20% to 5% more 15 preferably from 0.25% to 2.5% by weight. These polymers and the previously mentioned homo- or co-polymeric polycarboxylate salts are valuable for improving whiteness maintenance, fabric ash deposition, and cleaning performance on clay, proteinaceous and oxidizable soils in the presence of transition metal impurities.
Soil release agents useful in compositions of the present invention are conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol andlor propylene glycol units in various arrangements. Examples of such polymers are disclosed in the commonly assigned US Patent Nos. 4116885 and 4711730 and European Published Patent Application No. 0 272 033. A particular preferred polymer in accordance with EP-A-0 272 033 has the formula (CH3(PEG)43)O.TS(POH)0.25Cr-PO)2.8(T-PEG)p.4lT(PO-H)0.25((PEG)43CH3)0.75 where PEG is -(OC2H4)O-,PO is (OC3H60) and T is (pcOC6H4C0).
Also very useful are modified polyesters as random copolymers of dimethyl terephthalate, dimethyl sulfoisophthalate, ethylene glycol and 1-2 propane diol, the end groups consisting primarily of sulphobenzoate and secondarily of mono esters of ethylene glycol and/or propane-diol. The target is to obtain a polymer capped at both end by sulphobenzoate groups, "primarily", in the present context most of said copolymers herein will be end-capped by sulphobenzoate groups.
However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or propane 1-2 diol, thereof consist "secondarily" of such species.
The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of propane -1.2 diol, about 10% by weight ethylene glycol about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about ~0 3.000. The polyesters and their method of preparation are described in detail in EPA 311 342.
It is well-known in the art that free chlorine in tap water rapidly deactivates the enzymes---comprised in dEtergent compositions. Therefore, using chlorine ~ 5 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.
