COATED SODIUM PERCARBONATE PARTICLES, PROCESS FOR THEIR PREPARATION, THEIR USE AND DETERGENT COMPOSITIONS CONTAINING THEM |
摘要 |
Coated sodium percarbonate particles containing a sodium percarbonate core surrounded by at least one coating layer comprising at least one inorganic coating material, the coated particles having a content of available oxygen of at least 3 % by weight, and being fizzy to such an extent that 2 g of the coated particles dissolved in 50 ml of water at 20°C generate more than 0,4 ml of gas after 2 min. Process for the preparation of such coated sodium percarbonate particles comprising a heat treatment. |
