Abstract
The storage stability of aqueous enzymatic liquid detergent compositions is improved by the inclusion therein of a stabilizing system comprising a poly-functional amino compound such as triethanolamine and boric acid or a boron-equivalent thereof.
Claims5
An aqueous enzymatic liquid detergent composition with improved storage stability, said composition having a pH of 7.5-11.0 and comprising a stabilizing system comprising
- (a) about 2 to about 25% by weight of the final composition of a polyfunctional amino compound selected from the group consisting of diethanolamine, triethanolamine, di-isopropanolamine, triisopropanolamine and tris(hydroxymethyl) aminomethane;
- (b) about 0.25 to about 15% calculated on the basis of boric acid by weight of the final composition of a boron compound selected from the group consisting of boric acid, boric oxide, borax, sodium ortho-, meta- and pyroborate.
