Abstract
A liquid detergent composition including a liquid detergent composition base and active-containing capsules of 200 μM diameter maximum, characterised in that the base has a pH of from 7-11 and additionally contains a suspension agent, which includes a combination of a hydrophilic clay and a polymeric thickening agent, which thickening agent is an alkali metal salt of a polycarboxylic acid. The capsules remain uniformly dispersed in the composition for long periods, thus allowing the benefit of the active to be retained for the life of the composition.
Claims16
A liquid detergent composition, comprising a liquid detergent composition base and active-containing capsules of 200 μm diameter maximum, characterised in that the base has a pH of from 7-10 and additionally contains a suspension agent, which comprises a combination of a hydrophilic clay and a polymeric thickening agent, which thickening agent is an alkali metal salt of a polycarboxylic acid.
A method of making a microcapsule-containing liquid detergent composition, comprising the addition to a liquid detergent base of active-containing microcapsules;
- characterised in that
- (a) there is first added to the base a polymeric thickening agent, which polymeric thickening agent is an alkali metal salt of a polycarboxylic acid;
- (b) the pH is adjusted to a value of from 7-10;
- and
- (c) the microcapsules are added as an aqueous slurry;
- a hydrophilic clay being additionally added to the composition at at least one of these stages.
A method of making a microcapsule-containing liquid detergent composition, comprising the incorporation of active-containing microcapsules in a liquid detergent composition base comprising detergent surfactants and other standard ingredients;
- by the steps of
- (a) adding to water a polymeric thickening agent, which polymeric thickening agent is an alkali metal salt of a polycarboxylic acid;
- (b) adding to the solution of (a) the detergent surfactants of the liquid detergent composition base;
- (c) adjusting the pH to a value of from 7-11;
- and
- (d) adding the other standard ingredients of the liquid detergent composition base;
- there being additionally added at any of the stages (a)-(d) an aqueous slurry of active-containing microcapsules and a hydrophilic clay.
