Abstract

The invention provides a process to coat dry particles comprising sodium carbonate perhydrate to provide a stable dry particulate solid which releases hydrogen peroxide when contacted with an aqueous solution. The coated particles are readily soluble in water and/or stable when formulated into a solid detergent.
