Abstract
Abstract A stabilized built single-phase enzyme-containing liquid detergent composition is provided comprising: (a) from about 3 to 10%, by weight, of a surface active nonionic detergent compounds; (b) from about 3 to 15%, by weight, of a surface active amphoteric detergent compound; (c) from about 5 to 25%, by weight, of a water-soluble non-phosphate detergent builder salt; (d) an effective amount of an enzyme or enzyme mixture selected from the group consisting of alkaline protease enzymes and alpha-amylase enzymes; (e) from about 3 to 15%, by weight, of an enzyme stabilizing system consisting essentially of (i) glycerine and (ii) a boron compound selected from the group consisting of boric acid, boric oxide and alkali metal borates capable of reacting with said glycerine; and (f) from about 30-85%, by weight, water; said liquid detergent composition being substantially free of cross-linked polyacrylate polymers.
