SODIUM PERCARBONATE PARTICLES WITH INCREASED STABILITY DURING STORAGE Russian patent published in 2008 - IPC C11D17/00 C11D3/395 B01J2/30 

Abstract RU 2337135 C2

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.
