Abstract
Sodium percarbonate particles with a coating layer which comprises from 70 to 99.8% by weight of anhydrous sodium sulfate and from 0.2 to 20% by weight of a sodium borate, and whose proportion by weight is from 1 to 10% based on the mass of the sodium percarbonate particle, exhibit a high storage stability in detergent and cleaning composition formulations through a synergistic effect of sodium sulfate and sodium borate on the storage stability, and at the same time only have a small content of boron.
