摘要： A stabilized enzyme-containing built liquid detergent is provided comprising(a) from about 5 to 20%, by weight, of one or more surface active detergent compounds selected from the group consisting of anionic, nonionic and amphoteric detergent compounds;from about 5 to 30%, by weight, of one or more builder salts selected from the group consisting of alkali metal tripolyphosphates, alkali metal carbonates, alkali metal nitrilotriacetates and polyacetal carboxylates;(c) from about 5 to 20%, by weight, of a swelling bentonite clay;(d) an effective amount of an enzyme or an enzyme mixture selected from the group consisting of alkaline protease enzymes and alpha-amylase enzymes;(e) an enzyme-stabilizing system containing, based on the weight of the detergent composition, (i) from about 1% to 10% glycerine; (ii) from about 1 to 8% of a boron compound selected from the group consisting of boric acid, boric oxide and alkali metal borates; and (iii) from about 0.5 to 8% of a carboxylic acid compound selected from the group consisting of mono, di and/or polycarboxylic acids having 1 to 8 carbon atoms and water-soluble salts thereof; and(f) the balance comprising water.
