Application 10/122,855
6. The detergent composition according to claim 13, including from
about 0.1% to about 1% by weight said polyhydroxy compound.
8. A process for stabilizing an amylase enzyme in an aqueous
enzymatic liquid or gel detergent composition, comprising the steps of:
(a) providing an enzyme stabilizing combination comprising:
(i) from about 0.1% to about 15% by weight, boric acid;
(ii) from about 0.1% to about 10% by weight, a
polyhydroxy compound selected from the group consisting of ethylene

glycol, mannitol, sorbitol, erythritol, glucose, fructose, lactose, erythritol-
1,4-anhydride, and mixtures thereof; and
(iii) an oxygen bleach resistant α-amylase enzyme; and
(b) mixing said enzyme stabilizing combination with liquid
detergent ingredients, wherein the oxygen bleach resistant α-amylase
enzyme does not comprise Termamyl alpha amylase enzyme.
10. The process according to claim 8 comprising, by weight of the
composition, from 1% to 5% of boric acid, from 0.1% to 7% of the
polyhydroxy compound, and from 0.1% to 2% of the oxygen bleach resistant
α-amylase enzyme.
11. The process according to claim 8 comprising from 40% to 70%
water, and wherein the polyhydroxy compound is 1,2-propanediol.
13. An aqueous liquid or gel detergent composition, comprising:
(e) from about 0.1% to about 15% by weight, boric acid;
