Abstract
Liquid compositions containing a perborate bleaching system having improved chemical stability over existing systems are prepared by suspending a salt of a superperborate in a non-aqueous liquid. The superperborate salts have an available oxygen content of greater than 16.1%, and an empirical chemical formula of the type Na.sub.x B.sub.y O.sub.z.nH.sub.2 O where x is 1-4, y is 1-5, z is 2-15 and n is 1-5. The ratio of x:y is between 0.5 to 1.2:1. The compositions may include surfactants, activators and detergent auxiliaries. Preferred surfactants are nonionic surfactants. When a surfactant is present, the compositions are bleach containing liquid detergents. When surfactants are not present, the compositions can be used as bleach additives or non-detergent cleaners.
