SODIUM PERCARBONATE PARTICLES, METHOD OF THEIR PRODUCTION, THEIR APPLICATION, DETERGENT COMPOSITIONS, CONTAINING THEM Russian patent published in 2010 - IPC C01B15/10 

FIELD: chemistry.

SUBSTANCE: invention relates to sodium percarbonate particles. Essence of invention: described are particles of sodium percarbonate, provided with coating and consisting of main particles of sodium percarbonate, surrounded with at least one layer of coating, possessing long storage stability, expressed as amount of released heat at 40°C, measured after 12-week long storage at temperature 40°C, which constitutes less than 5 mcW/g. Subject of invention also are sodium percarbonate particles, provide with coating and consisting of main particles of sodium percarbonate, surrounded with at least, one layer of coating, possessing long storage stability, expressed as preservation of available oxygen content after 8-week long storage at temperature 55°C, which constitutes at least 70%. Also subject of invention are method of said sodium percarbonate particles production and application of said particles in detergent compositions as bleach, and detergent compositions, containing described sodium percarbonate paprticles.

EFFECT: creation of sodium percarbonate particles possessing increased long storage stability.
