  • Particulate aluminosilicate-built detergent compositions comprising cogranules of zeolite map and alkali metal silicate
    Patent number: 5854198
    Abstract: In order to enhance the stability of sodium percarbonate bleach in particulate detergent compositions, crystalline aluminosilicate and a water-soluble alkali metal silicate in an amount of from 1-20% by weight based on the aluminosilicate are included in the non-spray dried base powder. In order to obtain the stabilizing effect, the crystalline aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.
