Abstract (en)

[origin: WO9703156A1] There is provided a detergent composition comprising: a) from 1 % to 95 % by weight of a surfactant system comprising an anionic surfactant and a cationic ester surfactant, other than N,N-di(2-stearoyloxyethyl)-N-(2-hydroxyethyl)-N-methyl ammonium chloride, present in a weight ratio of said anionic surfactant to said cationic ester surfactant of 2.5:1 to 25:1; and b) from 0.0001 % to 5 % by weight of a proteolytic enzyme, wherein the % weight of proteolytic enzyme in the formulation is based on an enzyme activity of 4 Knpu/g of the enzyme particle, and wherein the weight ratio of said anionic surfactant to said proteolytic enzyme is at least 1.5:1.
