FIELD: chemistry.
SUBSTANCE: sodium percarbonate particles have bleaching effect, their surface contain hydrophobized superfine silica in proportion 0.01-1 wt %. Method for proposed particles production consists in mixing of sodium percarbonate particles, preferably being dried, and 0.01-1 wt % of hydrophobized superfine silica. Particles of the invention have high stability during storage, permit handling and storage without dust formation and agglutination; they are dispersed in water readily and completely.
EFFECT: simplification of particles obtaining technology, and reducing equipment needed.
