PARTICLES HAVING CORE AND COMPRISING PEROXY COMPOUND (VARIANTS), METHOD FOR THEIR PRODUCTION, COMPOSITION COMPRISING THEM Russian patent published in 1998 - IPC

FIELD: production of detergents. SUBSTANCE: particles comprise corn and coating. Hydrogen peroxide or peroxy acids being isolated into aqueous solutions represent themselves the base for these particles. Corn and coating at the same time or separately may comprise chelating agent, its quantity in coating being from about 0.1 mass % to about 15 mass %. Said chelating agent is chosen of group comprising salts of alkaline or alkaline-earth metal and oxycarboxylic acid having formula RCnHm(OH)_nCOOH wherein R is CH₂OH or COOH, n= 2-6, m= 0-n. Method for production of particles is carried out by mixing components followed by granulation. Then coating is applied. Desired particles have increased stability, activity of peroxy compounds may be significantly increased with the help of desired particles. EFFECT: improved quality of desired product, improved efficiency of the method. 29 cl, 2 tbl
