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.
Claims7
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.
