The Present Invention:
One difficulty with prior detergent-formulations containing lipase is that there is a strong tendency for many detergent-active materials to inhibit the action of the lipase.
It is an aim of the present invention to provide detergent formulations in which the activity of added lipase is relatively less inhibited.
According to the present invention there is provided an enzyme-cont~ ing detergent composition for washing fabrics, comprising:
~3~ *denotes tr~de mark ~ 4 ~ 2 005022 1) 1 to 60% by weight of a surfactant system S consisting of (a) at least 50% by weight of a primary alcohol sulphate having a chain length in the range of C12 to C~8; and (b) 0 to 50% by weight of a surfactant selected from the group consisting of anionic surfactants other than primary alcohol sulphates, nonionic surfactants, cationic surfactants and mixtures thereof; and 2) lipase enzyme in an amount in the range 50 to 30,000 (LU) lipase units per gram of the surfactant system or of the detergent composition, together with conventional detergent adjuncts.
In this specification lipase units are defined as they are in EP 0 258 068 (Novo).
In most practical embodiments, the ingredients of the detergent compositions also include e.g. conventional detergent ad~uncts such as one or more of those mentioned below.
It has been found that, in the composition of the invention, lipase enzyme shows surprisingly little inhibition. One reason for surprise at good performance of ' ~3 ~4~~ 2005022 lipase in this system is that at least one member of the cla~s of primary alcohol sulphates, i.e. sodium dodecyl sulphate, i~ well-known and used in laboratory investigations as a denaturant for proteins including enzymes. By comparison with a lipase-cont~i n ing surfactant based on alpha-olefin sulphonate, the compositions of the present invention show stronger detergent action combined with ade~uately low levels of lipase inhibition.
It is also surprising that the (known) building effect of primary alcohol sulphate and it~ high calcium affinity by comparison with the highly inhibitory LAS surfactants does not lead to greater degrees of lipa3e ~ ~, _ /

The primary alcohol sulphates used in these compositions can for example be based on coco-primary alcohol sulphates or tallow-primary alcohol slllrh~tes or mixtures of these with each other and/or analogues having alkyl chAinc derived from other sources.
Also permissible in the compositions are quantities of other surfactant types, especially anionic, nonionic or cationic detergents, in small or minor amounts e.g. up to 10%, possibly up to 20% or up to 35%, sometimes up to 50%, of the surfactant system, e.g. linear alkyl-benzene sulphonates (LAS) or (branched-chain) alkylbenzene sulphonates (ABS), which alone have been found to show unacceptably high degrees of inhibition of lipase.
In certain examples of the compositions of the invention, especially for example those illustrated in Example 11-13 below, the alkylbenzene sulphonates (LAS or ABS) may be present at up to about 66%, or in some cases up to about 70% or even 75%, of the surfactant system including the primary alcohol sulphate.
For example, certain of the formulations may comprise a surfactant system consisting essentially of a mixture of PAS with ABS and/or LAS. Here the proportion of ABS or LAS in such mixture may be for example up to about 75%, e.g. up to about 70%, often somewhat lower as for example about 66% or 60%, by weight.
A preferred surfactant system for use in this invention is based on a mixture (e.g. about 1:1 w/w) of C12-C14 coco-alkyl and C16-C18 tallow-alkyl sulphates.
20~S022 The lipolytic enzyme can usefully be added in the form of a granular composition of lipolytic enzyme with carrier material.
The added amount of lipolytic enzyme can be chosen within wide limits, for example 50 to 30,000 LU/g of granular detergent composition, e.g. often at least 100 LU/g, very usefully at least 500 LU/g, sometimes preferably above 1000, above 2000 LU/g or above 4000 LU/g or more, thus very often within the range 50-4000 LU/g and possibly within the range 200-1000 LU/g.
The lipolytic enzyme can be chosen from among a wide range of lipases: in particular the lipases described in for example the following patent specifications, EP O
214 761 (Novo), EP 0 258 068 (Novo) and especially lipases showing immunological cross-reactivity with antisera raised against lipase from Thermomyces lanuginosus ATCC 22070, EP 0 205 208 (Unilever) and EP 0 206 390 (Unilever), and especially lipases showing immunological cross-reactivity with antisera raised against lipase from Chromobacter viscosum var lipolyticum NRRL B-3673, or against lipase from Alcaligenes PL-679, ATCC 31371 and FERM-P 3783, also the lipases described in specifications WO 87/00859 (Gist-Brocades) and EP 0 204 284 (Sapporo Breweries). Suitable in particular are for example the following commercially available lipase preparations: Novo Lipolase, Amano Iipases CE, P, B, AP, M-AP, AML, and CES, and Meito lipases MY-30, OF, and PL, also esterase MM, Lipozym, SP225, SP285, Saiken lipase, Enzeco lipase, Toyo Jozo lipase and Diosynth lipase (Trade Marks).
Genetic engineering of the enzymes can be achieved by extraction of an appropriate lipase gene, e.g. the 20050;~2 gene for lipase from Thermomyces lanuginosus or from a mutant thereof, and introduction and expression of the gene or derivative thereof in a suitable producer organism such as an Aspergillus. The t~chniques described in WO 88/02775 (Novo), EP 0 243 338 (Labofina) and EP 0 268 452 (Genencor) may be applied and adapted.
A preferred non-limitative example of a granular or powder-form detergent composition according to the present invention comprises:
Primary alkyl sulphate 9 (50:50 coco/tallow alkyl sulphates) Sodium sulphate 34.4%
Sodium carbonate 6.7%
Sodium chloride 3.4%
Sodium C-Silicate 6.5%
Zeolite A (anhydrous) 30.2%
Sokolan CP5 (TM) 4.5%
Synperonic A4 (TM) 4%
(polyethoxylated alcohol c. C12-E4) Lipase (Lipolase 30T granulate, Novo) 1 or lipase from Pseudomonas gladioli.
The detergent compositions may furthermore include the following usual detergent ingredients in the usual amounts. They may be built or unbuilt, and may be of the zero-P type (i.e. not contA;n;ng any phosphorus-containing builders). Thus the composition may contain from 1-4S%, e.g. 5-30~ by weight of one or more organic and/or inorganic builders. Typical examples of such builders include alkali metal ortho, pyro, and tripolyphosphates, alkali metal carbonates, either alone or in admixture with calcite, alkali metal citrates, alkali metal nitrilotriacetates, carboxymethyloxysuccinates, zeolites, polyacetalcarboxylates and so on. Furthermore, they may contain from 1-35% of a bleaching agent or a bleach precursor or a system comprising bleaching agent and/or precursor with activator therefor. Further optional ingredients are lather boosters, foam depressors, anticorrosion agents, soil-suspending agents, sequestering agents, anti-soil redeposition agents, perfumes, dyes, stabilising agents for the enzymes and so on. The enzymes other than lipase that may be present include protease, amylase, oxidase and cellulase.
The compositions may be formulated in any desired way, e.g. as powders, bars, pastes, liquids.
The compositions can be used for the washing of textile materials, especially but without limitation cotton and polyester-based textiles and mixtures thereof.
Especially suitable are for example washing proc~sses carried out at temperatures of about 60-65 deg C or lower, e.g. about 30-35 deg C or lower.
The invention is further illustrated non-limitatively by the following examples, which also show the performance estimated in terms of reflectance at 460nm of test cloths soiled with lipid and then washed, after 5 washes with a number of different lipase-containing detergent formulations.
201~5022 - g - C3287C
Examples 1-5 In each example, a detergent formulation was used to wash cotton test cloths soiled with a fatty mix based on olive oil (up to 10-15% by weight of the test cloths) after three-times prewashing. The detergent formulations used corresponded to the one given in detail above, except for the use of various surfactant systems (each in 10 an amount of 9% by weight) as follows:
Ex 1 Coco-alkyl sulphate (Elfan 280 ex Akzo) Ex 2 Tallow-alkyl sulphate (Sulphopon T55 ex Henkel) Ex 3 50:50 coco-alkyl/tallow-alkyl sulphates Ex 4 25:25:50 coco-alkyl-tallow alkyl-DOB113 Ex 5 DOB113 (linear alkyl benzene sulphonate alone for comparison) In the above formulation, 'DOB113' refers to the sulphonation product of Shell alkylbenzene DOB113 (TM).
Examples 6-10 correspond to Examples 1-5 except for wash temperature.
In each example, isothermal washes were performed at 30 deg.C. or 60 deg.C. for 30 minutes with and without lipase enzyme, with predissolved detergent compositions used at 4 g/l. Cloth/Liquor ratios were uniformly 10:1 containing 50:50 soiled:unsoiled load.
In each experiment, one of two lipases was used:
Lipolase from Novo as specified above, or lipase from Pseudomonas gladioli, used in the form of a conventionally purified culture preparation (600 LU/mg) at equivalent lipase activity to that of the Lipolase.
Results are quoted as average reflectances at 460nm of S test pieces after 5 soil/wash cycles.
Examples 1-5 were carried out at 60 deg C, Examples 6-10 were carried out at 30 deg C.
Reflectances (% at 460nm):
Control (no lipase) Experiments (Lipolase) ('gladioli') Ex 1 68 72 73.4 Ex 2 68.3 73.8 73.9 Ex 3 69.6 72.8 73.5 Ex 4 68.7 74.0 74.2 Ex 5 71.8 71.9 72.8 Ex 6 69 72.3 73.7 Ex 7 69.2 72.1 73.6 Ex 8 70.6 70.9 73.3 Ex 9 69.6 71.9 73.4 Ex 10 70.5 71.2 73.2 The results generally show an incremental benefit due to lipolytic activity. The general trend is to show that lipase in the presence of LAS-type detergent gives substantially less benefit (ex 5,10) than on average in the other examples (primary alcohol sulphates and their mixtures), which are accordingly preferred for use.
Examples 11 to 13 The following detergent bar formulations support well the liplytic action of lipase.
Primary alcohol sulphate (PAS) 28 15.5 12 (e.g. EMAL 10, ex Kao Corp, av. chain length C10) Alkyl-benzene sulphonate (ABS) -- 15.5 18 (e.g. from Escane F ex Exxon, av. chain length C11) Sodium pyrophosphate 16 10 10 Soda ash 10 18 18 Calcite 32 31 31 Aluminosilicate 2 2 2 Lipolase Minors and Water to 100% in each case.
The formulations are compounded in per-se conventional manner for detergent bars.
The present invention is susceptible of modifications and variations, and the present disclosure extends to the use of all combinations and subcombinations of the features described herein, optionally in combination with each of the features of the above-cited published patent specifications.

Control (no lipase) Experiments (Lipolase) ('gladioli') Ex 1 68 72 73.4 Ex 2 68.3 73.8 73.9 Ex 3 69.6 72.8 73.5 Ex 4 68.7 74.0 74.2 Ex 5 71.8 71.9 72.8 Ex 6 69 72.3 73.7 Ex 7 69.2 72.1 73.6 Ex 8 70.6 70.9 73.3 Ex 9 69.6 71.9 73.4 Ex 10 70.5 71.2 73.2 The results generally show an incremental benefit due to lipolytic activity. The general trend is to show that lipase in the presence of LAS-type detergent gives substantially less benefit (ex 5,10) than on average in the other examples (primary alcohol sulphates and their mixtures), which are accordingly preferred for use.
Examples 11 to 13 The following detergent bar formulations support well the liplytic action of lipase.
Primary alcohol sulphate (PAS) 28 15.5 12 (e.g. EMAL 10, ex Kao Corp, av. chain length C10) Alkyl-benzene sulphonate (ABS) -- 15.5 18 (e.g. from Escane F ex Exxon, av. chain length C11) Sodium pyrophosphate 16 10 10 Soda ash 10 18 18 Calcite 32 31 31 Aluminosilicate 2 2 2 Lipolase Minors and Water to 100% in each case.
The formulations are compounded in per-se conventional manner for detergent bars.
