Abstract

Detergent compositions are described having more than one enzyme, in particular having a multi-enzyme co-particle as well as methods of making and using such detergents. The compositions also have low levels of zeolite and phosphate builders and a moisture sink to minimize interaction between enzymes.

First claim

What is claimed is:

1. A detergent composition comprising:
(a) a multi-enzyme co-granule comprising from 10 to 98 wt % moisture sink component;
(b) less than 3 wt % zeolite (anhydrous basis);
(c) less than 3 wt % phosphate salt (anhydrous basis);
(d) from 5 wt % to 35 wt % of sodium percarbonate,
(e) a fabric shading dye selected from solvent, dyes, disperse dyes, acid dyes, direct dyes, pigment or mixtures thereof,
(f) a protease enzyme,
(g) a lipase enzyme,
(h) and the composition additionally comprises from 40 to 75 wt % detergent moisture sink component,
wherein the multi-enzyme co-granule has a core-shell structure, wherein the core comprises a central part free of the enzymes and a surrounding layer comprising the enzymes, wherein the shell comprises a plurality of layers, wherein a central part of the core and at least one of the shell layers comprises the moisture sink component, the most outer layer is titanium oxide and polyvinyl alcohol and is from 1% to 3% by weight of the total particle, wherein the central part of the core is from 5% to 40% by weight of the total particle and the layer comprising the moisture sink component is from 3% to 20% by weight of the particle, wherein the detergent moisture sink component is sodium sulphate, wherein the co-granule has a weight geometric mean particle size of from about 600 microns to about 1000 microns.

2. A detergent composition according to claim 1 wherein the multi-enzyme cogranule comprises (a) one or more enzymes selected from the group consisting of first-wash lipases, cleaning cellulases, xyloglucanases, perhydrolases, peroxidases, lipoxygenases, laccases and mixtures thereof; and (b) one or more enzymes selected from the group consisting of hemicellulases, care cellulases, cellobiose dehydrogenases, xylanases, phospholipases, esterases, cutinases, pectinases, mannanases, pectate lyases, keratinases, reductases, oxidases, phenoloxidases, ligninases, pullulanases, tannases, pentosanases, lichenases glucanases, arabinosidases, hyaluronidase, chondroitinase, amylases, and mixtures thereof.

3. A detergent composition according to claim 1 wherein the multi-enzyme co-granule comprises lipase and protease in a weight ratio of from 2:5 to 1:1.

4. A detergent composition according to claim 1 wherein the moisture sink component and the total active enzyme are present in the multi-enzyme co-granule in a weight ratio from 4:1 to 40:1.

5. A detergent composition according to claim 1 further comprising a dye transfer inhibiting agent.

6. A detergent composition according to claim 1 further comprising one or more of the following adjuncts:
(a) an encapsulate comprising a perfume;
(b) a surfactant system comprising an anionic surfactant and a nonionic surfactant in the weight ratio from 20:1 to 1:10;
(c) a silicate salt selected from the group consisting of sodium silicate, potassium silicate and mixtures thereof;
(d) a carboxylate polymer selected from the group consisting of maleate/acrylate random copolymer or polyacrylate homopolymer and mixtures thereof;
(e) a soil release polymer selected from the group consisting of terephthalate co-polymers and mixtures thereof;
(f) a cellulosic polymer selected from the group consisting of alkyl cellulose, alkyl alkoxyalkyl cellulose, carboxyalkyl cellulose, alkyl carboxyalkyl cellulose and mixtures thereof;
(g) a chelant selected from the group consisting of DTPA (Diethylene triamine pentaacetic acid), HEDP (Hydroxyethane diphosphonic acid), DTPMP (Diethylene triamine penta(methylene phosphonic acid)), ethylenediaminedisuccinic acid (EDDS), 1,2-Dihydroxybenzene-3,5-disulfonic acid disodium salt hydrate, derivatives of said chelants; and
(h) mixtures thereof.

7. A composition according to claim 1 further comprising one or more bleach particles selected from the group consisting of:
(a) a bleach catalyst comprising a material selected from the group consisting of iminium cations, iminium polyions; iminium zwitterions; modified amines; modified amine oxides; N-sulphonyl imines; N-phosphonyl imines; N-acyl imines; thiadiazole dioxides; perfluoroimines; cyclic sugar ketones, transition metal catalysts or ligands for the formation thereof, and mixtures thereof;
(b) a bleach activator comprising a material selected from the group consisting of dodecanoyl oxybenzene sulphonate, decanoyl oxybenzene sulphonate, decanoyl oxybenzoic acid or salts thereof, 3,5,5-trimethyl hexanoyloxybenzene sulphonate, tetraacetyl ethylene diamine (TAED), nonanoyloxybenzene sulphonate (NOBS) and mixtures thereof;
(c) a metal catalyst;
(d) a photo-bleach selected from the group consisting of zinc aluminium phthalocyanine compounds, Food red, erythrosine, Rose Bengal, and mixtures thereof; and
(e) mixtures thereof.
