Abstract (en)
[origin: EP0199405A2] Liquid detergent compositions containing synthetic surfactant, specific proteolytic enzyme, boric acid or a boron compound capable of forming boric acid in the composition, and calcium ion are disclosed. The compositions exhibit improved enzyme stability because boric acid stabilizes the proteases herein to a greater degree than it does other proteases. Preferred laundry detergent compositions containing anionic surfactant and detergency builder also provide improved cleaning performance, particularly through-the-wash, on enzyme-sensitive stains.
