Abstract:
A stable aqueous enzyme composition comprising:(a) water;(b) from 0.1 to about 75% by weight of a detergent surfactant selected from the group consisting of anionic surfactants and anionic surfactants and one or more non-anionic detergent actives, wherein the weight ratio of anionic surfactant to non-anionic detergent active is greater than 1: 1 when there is a mixture of anionic surfactant and non-anionic detergent active;(c) from 0.001% to about 10% by weight proteolytic enzyme; and(d) an enzyme stabilizer in an amount effective to stabilize said enzyme, said stabilizer having the formula:X--O--(C.sub.n H.sub.2n O).sub.a --H [I]wherein ""X"" is an organic radical having from 16 to 22 carbon atoms, ""a"" is an integer from 14 to 26, and ""n"" is an integer from 2-4, wherein said one or more non-anionic detergent actives, if present, can comprise said enzyme stabilizer, said aqueous enzyme composition having a pH of from 6 to 7.
