COATED SODIUM PERCARBONATE PARTICLES

摘要

Sodium percarbonate particles with a coating layer that contains 70 to 99 .8% by weight moisture free sodium sulphate and 0.2 to 2% by weight of a sod ium borate, the proportion by weight of the coating layer ranging from 1 to 10% relative to the mass of the sodium percarbonate particles, exhibit high storage stability in detergent and cleaning agent preparations, due to a syn ergistic effect of sodium sulphate and sodium borate on storage stability, a nd at the same time have only a low boron content.
