FIELD: chemistry.
SUBSTANCE: invention relates to a particle of a bleaching agent, which has a) core, which contains more than 70 wt % of sodium percarbonate, b) internal envelope, containing sodium sulphate in the form of thenardite or burkeite in an amount of at least 50 wt %, and c) internal envelope, containing a water-soluble binding agent and at least one bleaching activator, selected from capable of perhydrolysis N-acyl and O-acyl compounds. The invention also relates to a method of obtaining the particle and to a detergent.
EFFECT: particles of the bleaching agent are stable in storage, suitable for storing in bins and make it possible to transport them safely and to work with them even in a hot and wet climate.
