The invention pertains to aqueous, enzymatic liquid detergent compositions which contain an enzyme-stabilizing system. The replacement of polyols in known enzyme-stabilizing systems on the basis of mixtures of a polyol with a boron compound, such as boric acid or borax, or with a reducing salt, such as sodium sulphite, by a dicarboxylic acid, such as succinic acid, also provides for an effective, often superior enzyme-stabilizing system.

An aqueous, enzymatic liquid detergent composition comprising, in an aqueous liquid medium, as essential ingredients, from 1-60% by weight of an active detergent material selected from the group consisting of soap, anionic, nonionic, cationic, zwitterionic and amphoteric surfactants and mixtures the
An aqueous, enzymatic liquid detergent composition comprising, in an aqueous liquid medium, as essential ingredients, from 1-60% by weight of an active detergent material selected from the group consisting of soap, anionic, nonionic, cationic, zwitterionic and amphoteric surfactants and mixtures thereof, from 1-60% by weight of a detergent builder, from 0.001-10% by weight of bacterial or fungal enzymes and a stabilizing system for said enzymes, wherein the stabilizing system consisting essentially of a mixture of (A) an inorganic compound selected from the group consisting of boric acid, boric oxide, alkalimetal borate, a reducing alkalimetal salt having an oxygenated sulphur anion SaOb, in which a and b are whole numbers from 1 to 8, and mixtures thereof, and (B) a dicarboxylic acid of the general formula COOH－(CHOH)a－(CH2)b－(CHOH)c－(CH2)d－COOH in which a, b, c and d are whole numbers from 0-4, the sum of a, b, c and d being from 0-4, whereby, when a=c=0 and b=c=1, the corresponding dicarboxylic acid may also be unsaturated, or the alkalimetal, ammonium, alkanolamine or alkaline earth metal salts thereof, whereby the amount of (A) is from 1-15% by weight for the boron compounds and from 2-20% by weight for the reducing alkalimetal salt and the amount of (B) is from 0.5-15% by weight.
