Stabilized fabric softening built detergent composition containing enzymes
First Claim
1. A stabilized fabric softening enzyme-containing built liquid detergent composition comprising:
- (a) from about 5 to B 20%, by weight, of one or more surface active detergent compounds selected from the group consisting of anionic, nonionic and amphoteric detergent compounds;
(b) from about 5 to 30%, by weight, of one or more builder salts selected from the group consisting of alkali metal tripolyphosphates, and alkali metal carbonates;
(c) from about 5 to 20%, of a swelling bentonite clay;
(d) an effective amount of an enzyme or an enzyme mixture for stain removal selected from the group consisting of alkali 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 di and/or polycarboxylic acids selected from the group consisting of oxalic acid, malonic acid, maleic acid, succinic acid, malic acid, tartaric acid, aspartic acid and citric acid and water-soluble salts thereof;
(f) the balance comprising water.

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.
