ABSTRACT:
Sodium perborate particles are coated or at least partially coated with a salt of a lower alkyl siliconic acid and/or polymerization product(s) thereof which may be formed from such acid on storage. The coated sodium perborate particles are useful as components of heavy duty fabric softening laundry detergent compositions, such as those which contain bentonite to soften laundry. The coating material, which may be more simply referred to as the siliconate, assists in stabilizing the sodium perborate when such is incorporated in detergent compositions, helps to prevent adherence of the coated particles to container or compartment walls and can aid in controlling the foaming activity of the built synthetic organic detergents.
