ABSTRACT:
A process for reducing dissolution time in the production of sodium percarbonate particles containing an alkali metal silicate as stabilizer by fluidized bed spray granulation and/or by coating sodium percarbonate particles with a coating containing an alkali metal silicate, wherein a solution containing alkali metal silicate is sprayed during production and/or coating which contains alkali metal silicate having a modulus in the range from less than 3 to greater than 1. Sodium percarbonate produced by fluidized bed spray granulation is distinguished by elevated Oa stability and short dissolution times and may thus readily be used in detergents and cleaning products containing silicate builders.
