1. A liquid detergent composition comprising:
(a) a surfactant in an amount of 30% to 60% by weight of the composition; (b) water in an amount of 30% to 90% by weight of the composition; and (c) at least one particle comprising an enzyme and a polymer, which has a particle size below 100,000 nm, wherein the enzyme and polymer are present as a mixture in the particle at a polymer:enzyme weight ratio above 1, and the polymer is substantially soluble in an aqueous solution having an ionic strength of 0 mol/kg and insoluble in an aqueous solution having an ionic strength of more than 1 mol/kg and wherein the enzyme is released when the detergent is diluted,and wherein the polymer is a copolymer of between 50 and 70% w/w vinyl pyrrolidone (VP) and 30 to 50% w/w vinyl acetate (VA). |
