Definitions
- This invention relates to detergent compositions, and to their use, and in particular to compositions containing lipase and to their use.
- GB-A-1 372 034 discloses lipase from Pseudomonas in specific nonionic-containing detergent compositions for soaking fabrics.
- compositions comprise lipase and lipase activators and a number of lipases from microorganism and other sources are mentioned: those particularly mentioned as preferred are Amano CE, Amano M-AP, Takeda 1969-4-9, and Meito MY-30 (Trade Marks) lipases, but no indications are given of the form in which the lipase is to be prepared or used.
- EP-A-0 206 390 (Unilever), which relates to lipases related to those from Ps. fluorescens, P. gladioli and Chromobacter in detergent compositions, comprising a mixed anionic/nonionic surfactant system which amounts to 1 to 30% by weight of the composition.
- EP-A-0 214 761 gives detailed description of lipases derived from organisms of the species Pseudomonas cepacia, and certain uses therefor.
- EP-A-0 258 068 gives detailed description of lipases derived from organisms of the genus Thermomyces/Humicola, and certain uses therefor.
- a lipase-containing granular detergent composition containing about 37% detergent actives including 5% nonionic detergent and the remainder substantially anionic detergent, about 16% zeolite, about 60 LU/g lipase, plus protease and other normal detergent additives.
- lipase-containing detergent compositions are provided by JP-A-63-078000 (1988) (Lion Corp/K Mukoyama et al) which discloses properties and uses of a Pseudomonas lipase, including use in a lipase-containing system based on 10-40 % surfactant (e.g. sodium C12-C18 alpha-olefin sulphonate), as well as other conventional detergent ingredients.
- surfactant e.g. sodium C12-C18 alpha-olefin sulphonate
- EP-A-0 268 456 (Clorox), which shows in connexion with Table 10(b) an experimental washing solution containing lipase and about 1 microgram/ml sodium dodecyl sulphate.
- an enzyme-containing detergent composition for washing fabrics comprising:
- lipase units are defined as they are in EP-A-258 068 (Novo).
- the ingredients of the detergent compositions also include e.g. conventional detergent adjuncts such as one or more of those mentioned below.
- lipase enzyme shows surprisingly little inhibition.
- At least one member of the class of primary alcohol sulphates i.e. sodium dodecyl sulphate
- the compositions of the present invention show stronger detergent action combined with adequately low levels of lipase inhibition.
- the primary alcohol sulphates used in these compositions can for example be based on coco-primary alcohol sulphates or tallow-primary alcohol sulphates or mixtures of these with each other and/or analogues having alkyl chains derived from other sources.
- 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.
- surfactant system e.g. linear alkyl-benzene sulphonates (LAS) or (branched-chain) alkylbenzene sulphonates (ABS)
- certain of the formulations may comprise a surfactant system consisting essentially of a mixture of PAS with ABS and/or LAS.
- 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.
- 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 0 214 761 (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 lipases 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).
- Lipase gene e.g. the 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.
- a suitable producer organism such as an Aspergillus.
- the techniques described in WO-A-88/02775 (Novo), EP-A-0 243 338 (Labofina) and EP-A-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:
- 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 containing any phosphorus-containing builders). Thus the composition may contain from 1-45%, 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.
- 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.
- compositions may be formulated in any desired way, e.g. as powders, bars, pastes, liquids.
- 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 processes 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.
- 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 an amount of 9% by weight) as follows:
- 'DOB113' refers to the sulphonation product of Shell alkylbenzene DOB113 (TM).
- Examples 6-10 correspond to Examples 1-5 except for wash temperature.
- 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.
- 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 5 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.
- 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 used in the present invention.
- detergent bar formulations support well the lipolytic action of lipase.
- the formulations are compounded in per-se conventional manner for detergent bars.
