Abstract
A coated stabilized bleaching assistant suitable for use in pulverulent washing and bleaching compositions comprising drop-shaped to globular-shaped particles having an average diameter of 0.01 mm to 2.5 mm, and at least 70% of which have a diameter within the range of 0.1 mm to 1 mm consisting of 10% to 70% by weight of at least one activator for active oxygen derived from compounds yielding H.sub.2 O.sub.2 in aqueous solution, substantially surrounded by from 30% to 90% by weight of a mixture of (a) from 2 to 10 parts of substantially saturated fatty acids having 12 to 24 carbon atoms, (b) 1 part of aliphatic alcohols having 10 to 20 carbon atoms or their lower alkoxylated products having 1 to 5 alkoxy units, and (c) from 5 to 25% by weight of said mixture of water-soluble sulfates of aliphatic alcohols having from 8 to 18 carbon atoms or their lower alkoxylated products having 1 to 5 alkoxy units. The particles are obtained by spraying a fluid mixture of the components through a nozzle or by a spray disc, and cooling. The coated stabilized bleaching assistant can be incorporated with percompounds and other washing composition components.
