Heavy duty liquid detergent compositions containing non-proteolytic enzymes comprising capsules comprising proteolytic enzyme and composite polymer

Claim 1

A heavy duty liquid detergent comprising: (1) from about 5% to about 85% by weight of a surfactant selected from the group of surfactants consisting of anionic, nonionic, cationic, ampholytic or zwitterionic surfactants and mixtures thereof; (2) a non-proteolytic enzyme or enzymes ranging from 0.1-10% by weight enzyme based on the final composition; and (3) a polymer capsule comprising: (a) a proteolytic enzyme or enzymes; and (b) a composite emulsion polymer comprising (i) hydrophobic polymer core particles and (ii) a hydrophilic water soluble polymer or polymers chemically or physically attached to the hydrophobic core particles; wherein said hydrophilic polymer or polymers is not soluble in the detergent composition but is dissolved upon dilution of said composition with water and wherein said polymer is selected from the group consisting of polyvinyl alcohols having a percent hydrolysis ranging from about 70% to less than 95% and molecular weight under 50,000 and alkyl cellulose wherein said hydrophobic core particles are emulsion polymers prepared by polymerizing monomers selected from the group consisting of styrene, methylstyrene, vinylacetate, esters of acrylic acid, esters of methacrylic acid and mixtures of any of the monomers; the ratio of said hydrophobic core particles to hydrophilic water soluble polymer being from about 2:8 to about 7:3; wherein said proteolytic enzyme or enzymes are entrapped within a web formed by said hydrophilic polymer or polymers surrounding the hydrophobic core; wherein said polymer capsule comprises 0.1 to 10% by weight of the composition.
