Abstract (en)
[origin: WO2006063668A1] Disclosed are compressed molded bodies containing coated sodium percarbonate particles. Said compressed molded bodies comprise an inner coating layer that contains one or several water-soluble hydrate-forming salts as well as a superimposed outer coating layer which contains an alkali metal silicate. The inventive molded bodies are provided with an improved shelf life while the loss of active oxygen is low. Preferably, the molded bodies additionally contain at least one surfactant and other optional detergent substances. The disclosed molded bodies can be produced by forming tablets or briquettes from a powdered mixture while being usable in detergents or cleaning agents.
