COATED SODIUM PERCARBONATE PARTICLES, PROCESS FOR THEIR PRODUCTION, THEIR USE AND DETERGENT COMPOSITIONS CONTAINING THEM

摘要

Coated sodium percarbonate particles having a mean particle size of from 300 to 1600 µm containing a sodium percarbonate core surrounded by at least one coating layer, the coating layer comprising at least one coating agent and small sodium percarbonate particles of a mean particle size smaller than 100 µm. Process for the production of these particles by coating sodium percarbonate core particles with at least one coating agent and with small sodium percarbonate particles of a size smaller than 100 µm. Use of these particles as bleaching agent in detergent compositions and detergent compositions containing them.
