Abstract (en)

[origin: DE19619646A1] The invention proposes to improve the storage life of particulate alkali percarbonates, in particular, when used in washing and cleaning agents and also in the presence of bleaching activators substantially by the use of water-soluble salts which can absorb water of crystallization.
