ABSTRACT:
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.
