Abstract: Oxygen-bleach-containing liquid detergent compositions capable of providing remarkable cleaning and bleaching performance over a prolonged period of time are disclosed. The oxygen-bleach component is usually represented by hydrogen peroxide or equivalent addition products. The oxygen-bleach is stabilized with the aid of a binary system, namely: fatty acids and water soluble calcium salts, with the further understanding that the compositions are substantially free of conventional detergent polyphosphate. These bleach-containing liquid detergents are especially useful in boil-wash laundry treatments.
