AND A LACCASE ENZYME

TECHNICAL FIELD

The present invention relates to detergent compositions comprising a cellulase enzyme and a laccase enzyme.

BACKGROUND of the INVENTION

The detergency performance of enzymes in detergent products is judged by a number of factors, including the ability to remove soils and stains present in the typical load of the laundry.

In particular, coloured stains are problematic to remove. Coloured stains are based on carotenoids compounds such as a-"~- and y-carotene and Iycopene and xanthophyls, on porphyrins such as chlorophyll and on 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. Derivatives of cyanidin are present in up to 80% of the pigmented leaves, in up to 70% of fruits and in up to 50% of flowers. These stains typically originate from red wine, fruit such as black currant, cherry, strawberry and tomato (in particular ketchup and spaghetti sauce), . .

CA 022~4927 1998-11-12 W O 97/43381 PCT~US97/08035 vegetables such as carrots and beetroot, tea, coffee, spices such as curry and paprika, grass, or ball pens/ink.

Commercial detergents normally include bleaching agents to solve the above mentioned problem. Traditionally, high levels of bleaching agents, optionally with bleach precursors, are incorporated in detergent compositions.
Bleaching agents are compounds which are precursors of hydrogen peroxide;
hydrogen peroxide is then formed in the course of the washing procedure.
Perborates and percarbonates are the most important examples of such hydrogen peroxide precursors.

In addition, in recent years consumer desirability for fabric conditioning compositions has risen. Fabric care includes softening compositions which impart several desirable properties to treated garments including softness and static control. Fabric softness of laundered garments is typically achieved by delivering a quaternary ammonium compound to the surface of the fabric.
Consumer desirability for durable press fabric garments, particularly cotton fabric garments, has also risen. Durable press garments include those garments which resist wrinkling of the fabric both during wear and during the laundering process. Colour maintenance is also desirable.

Cellulolytic enzymes have been found to be particularly effective to meet these needs since these enzymes exhibit both cleaning and fabric care properties such as colour rejuvenation and depilling (EP-A-269 168, W089109259, EP-A-177 165, EP-A-495 257 and EP-A-495 258). Defining a cellulase selection criterion relevant for detergent application was made possible by the C14MC-method described in EP-A-350 098.

Given the foregoing, there is clearly a continuing need to provide detergent compositions which have an excellent overall detergency and fabric care performance.

Accordingly, it is an object of the present invention to formulate detergent compositions which provide effective and efficient cleaning of coloured stains and soils. It is a further object of the present invention to CA 022~4927 1998-ll-12 W O 97/43381 PCT~US97/08035 provide a laundry detergent composition which achieves excellent fabric care and cleaning.

It has now been surprisingly found that the bleaching performance of the laccase is synergistically enhanced by the presence of a cellulase. In addition, it has been found that the overall detergency and fabric care performance of the cellulase is synergistically enhanced by a laccase.

It has also been found that the detergent composition of the present invention provide sanitisation of the treated surfaces.

W091/05839 describes enzymes exhibiting a suitable oxidase activity or peroxidase activity for the inhibition of textile dye transfer from a dyed fabric to another fabric during the wash process. In particular, W095/01426 provides a detergent additive and a detergent composition comprising an enzyme exhibiting laccase activity, oxygen and an enhancing agent, which are capable of inhibiting the transfer of a textile dye from a dyed fabric to another fabric when said fabrics are washed together in a wash liquor.
Hospital laundry detergents containing an oxidase and a protease enzymes are disclosed in J64-60693. W093/13193 describes detergent compositions comprising a protease derived from Nocardiopsis and enzymes exhibiting a suitable oxidase activity or peroxidase activity, for stain bleaching and/or dyetransfer inhibition.

However, the combined use of a laccase and a cellulase for effective and efficient cleaning of coloured stains and soils has not been recognised;
nor the combined use of a laccase and a cellulase for excellent fabric care and cleaning properties.

SUMMARY of the INVENTION

The present invention relates to detergent compositions comprising a laccase enzyme and a cellulase enzyme, which provide effective and efficient cleaning of coloured stains and soils and sanitisation of the treated surfaces.

CA 022~4927 1998-11-12 W O 97/43381 PCTrUS97/08035 In a preferred embodiment, the present invention relates to a laundry detergent composition comprising a laccase enzyme and a cellulase enzyme for excellent fabric care and cleaning properties.

DETAILED DESCRIPTION of the INVENTION

Laccase and Laccase related enzymes Laccase and laccase related enzymes are an essential component of the detergent compositions of the present invention. It has been surprisingly found that the bleaching performance of the laccase is enhanced by the presence of a cellulase. Accordingly, the detergent compositions of the present invention provide effective and efficient cleaning of coloured stains and soils.

Without wishing to be bound by theory, it is believed that the cellulase enzymatic activity on the cellulolytic components of a coloured stain/soil and on cellulose based fibers and fabrics, renders the colour-bodies more accessible to the bleaching action of the laccase enzyme, resulting in improved removal of coloured stains and soils.

In addition, the detergent compositions of the present invention provide sanitisation of the treated surfaces.
Sanitisation includes all positive effects obtained by the inhibition or reduction of microbial activity on fabrics and other surfaces, such as the prevention of malodour development and bacterial/fungal growth. For example, it provides prevention of malodour development on stored and weared fabrics, on stored dishware, especially plastic kitchen gear and in toilets. In particular, the composition of the invention will inhibit or at least reduce the bacterial and/or fungal development on moist fabric waiting for further laundry processing and thereby preventing the formation of malodour.
In addition, bacterial and/or fungal growth on hard surfaces such as tiles and their silicone joints, sanitary installations, will be prevented.

The sanitisation potential of the detergent compositions of the present invention can be enhanced by the addition of chemical sanitisers such as Triclosan and/or hexemidine. Parfums Cosmétiques Actualités No 125, Nov, 1995, 51-4 describes suitable chemical sanitisers.
The sanitisation benefits of the detergent compositions of the present invention can be evaluated by the Minimum Inhibitory Concentration (MIC) as described in Tuber. Lung. Dis. 1994 Aug; 75(4~:286-90; J. Clin. Microbiol.
1994 May; 32(5):1261-7 and J. Clin. Microbiol. 1992 Oct; 30(10):2692-7.

1 lacc~se unit (LACU) is the amount of enzyme that catalyses the conversion of 1.0 ~mole syringaldazin per minute at these conditions.

Enhancing agents The detergent compositions according to the present invention may contain an enhancing agent.

According to the invention an enhancing agent is any compound that enhances the oxidation of the target soil or stain. The enhancing agent will typically be an oxidizable compound, e.g. a metal ion or a phenolic compound such as 7-hydroxycoumarin, vanillin, or p-hydroxybenzenesulfonate, (for reference see W0 92/18683, W0 92/18687 and Kato M and Shimizu S, Plant Cell Physiol. 1985 26 (7), pp. 1291-1301 (cf.

or Boehringer Mannheim; N-methylated derivatives of phenothiazine and phenoxazine may be prepared by methylation with methyliodide as described by Cornel Bodea and loan Silberg in "Recent Advances in the Chemistry of Phenothiazines" (Advances in heterocyclic chemistry, 1968, Vol.9, pp.321-460); B. Cardillo & G. Casnati in Tetrahedron, 1967, Vol. 23, p.3771.

Cellulase enzYmes The second essential element of the detergent composition of the present invention is a cellulase. It has been surprisingly found that the overall detergency and fabric care performance of the cellulase is synergistically enhanced by a laccase. Accordingly, the laundry detergent compositions of the present invention achieve excellent fabric care and cleaning.

CA 022~4927 l998-ll-l2 Without wishing ~o be bound by theory, it is believed that the bleach activity of the laccase enzyme enhances the cellulolytic activity on cellulose based cotton substrate. This enhanced cellulolytic activity results in enhanced fabric care and soil removal at the cotton fabric surface. The increased removal of worn cotton fibrils from the cotton fabric surface results in improved fabric feel and removal of the entrapped soils, especially particulate soils such as clay particles and carbon black particles. In addition, the accessibility of the soils and stains entrapped on the cotton fabric surface is enhanced and allows better laccase bleaching activity.

The cellulases usable in the present invention include both bacterial or fungal cellulases. Preferably, they will have a pH optimum of between 5 and 12 and an activity above 50 CEVU (Cellulose Viscosity Unit). Suitable cellulases are disclosed in U.S. Patent 4,435,307, Barbesgoard et al, J61078384 and W096/02653 which discloses fungal cellulase produced respectively from Humicola insolens, Trichoderma, Thielavia and Sporotrichum. EP 739 982 describes cellulases isolated from novel Bacillus species. Suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275; DE-OS-2.247.832 and W095/26398.

Examples of such cellulases are cellulases produced by a strain of Humicola insolens (Humicola grisea var. thermoidea), particularly the Humicola strain DSM 1800.
Preferred cellulases are cellulases originated from Humicola insolens having a molecular weight of about 50KDa, an isoelectric point of 5.5 and containing 415 amino acids; and a ~43kD endoglucanase derived from I lumicola insolens, DSM 1800, exhibiting cellulase activity. Another preferred endoglucanase component has the amino acid sequence disclosed in PCT
Patent Application No. WO 91/17243. Also suitable cellulases are the EGIII
cellulases from Trichoderma longibrachiatum described in W094/21801, Genencor, published September 29, 1994. Especially suitable cellulases are the cellulases having color care benefits. Examples of such cellulases are cellulases described in European patent application No. 91202879.2, filed November 6, 1991 (Novo). Carezyme and Celluzyme (Novo Nordisk A/S) are especially useful. See also WO91/17244 and WO91/21801. Other suitable CA 022~4927 1998-ll-12 W O 97/43381 PCTrUS97/08035 cellulases for fabric care and/or cleaning properties are described in W096/34092, W096/17994 and W095/24471.

Said cellulases are normally incorporated in the detergent composition at levels from 0.0001% to 2%, preferably 0.00015% to 0.6% of pure enzyme by weight of total composition.

In a prefer,ed embodiment, the present invention relates to a laundry and/or fabric care composition comprising a laccase and a cellulase (Examples 1-11). It has been found that the incorporation of a laccase enzyme and a cellulase enzyme in a softener matrix does also deliver effective and efficient cleaning of coloured stains and soils during the rinse cycle, with colour safety.
