FIELD: chemistry.
SUBSTANCE: invention refers to sodium percarbonate particles. According to the invention the coated sodium percarbonate particles possessing the inner shell layer including as basic component at least one inorganic hydrate-forming salt and outer shell layer including alkali metal thiosulphate, alkali-earth metal thiosulphate and/or ammonium thiosulphate are described. The method of such sodium percarbonate particles preparation and application of these particles as bleaching agent in detergents and cleansers are also the subjects of an invention.
EFFECT: increasing of stability of sodium percarbonate particles in detergents and cleansers during storage.
