1. A heavy-duty liquid detergent composition comprising, by weight:
- (a) from about 10% to about 50% of an anionic synthetic surfactant;
(b) from about 3% to about 30% of a C10 -C22 fatty acid;
(c) from about 2% to about 15% of a water-soluble detergency builder;
(d) from about 0.01% to about 5% of a proteolytic enzyme;
(e) from about 0.25% to about 10% of boric acid or a boron compound capable of forming boric acid in the composition;
(f) from about 0.05% to about 5% of a water-soluble formate;
(g) from about 1 to about 30 millimoles of calcium ion per liter of composition; and
(h) from about 20% to about 80% of water.

Abstract
Heavy-duty liquid detergents containing anionic surfactant, fatty acid, builder, proteolytic enzyme, boric acid or a boron compound capable of forming boric acid in the composition, formate, and calcium ion are disclosed. The combination of boric acid and formate provides improved protease stability in the compositions.
