Abstract (en)
The present invention provides a method for stabilizing enzymes in aqueous detergent compositions, which method comprises adding 3 to 50% by weight of a non-polymeric salt to said compositions to precipitate the enzymes into a separate phase and thereby protect the enzymes from other components left solubilized in the compositions. The invention further provides compositions having at least two phases provided in the process of the invention.
