PARTICLES WITH CORE FROM PEROXYCOMPOSITION, METHOD OF THEIR PRODUCTION, COMPOSITION FOR DISH WASHING, BLEACH Russian patent published in 1999 - IPC

FIELD: chemistry. SUBSTANCE: invention relates to particles with core from peroxycomposition capable to set free peroxy acid in aqueous solutions. The particles have coating including silicate of alkaline metal, chelating agent and 0.1-15% from particles mass aliphatic organic compound of the following formula R₁CnHm(OH)_p(COOH)_qR₂, where n = 1-8; m = 1-2n; p = 0-n; q = 0-2; one of R₁ and R₂ is group of COOH, the other, OH or COOH and silicate of alkaline metal which compound contains in the amount of 0.1-10% from particles mass. The invention also relates to the method of production and using the particles, and also to compound including such particles. The invention makes it possible to produce stable bleach which may be used in washing agents including zeolites. EFFECT: improved stability at storage; ecological harmlessness. 10 cl, 1 tbl, 1 ex
