    摘要: The invention relates to encapsulated bleaching agent particles. Said particles consist of a core that contains a bleaching-agent active ingredient and a coating of water-soluble material that at least partially surrounds said core, the core containing peroxocarboxylic acid and the coating material containing polyvinyl alcohol. The particles can be produced by introducing a particulate peroxocarboxylic acid into a fluidized bed, by spraying an aqueous solution containing polyvinyl alcohol onto said bed and by subsequent drying or spray drying.
