PARTICULATE ALUMINOSILICATE-BUILT DETERGENT COMPOSITIONS COMPRISING COGRANULES OF ZEOLITE MAP AND ALKALI METAL SILICATE

摘要

In order to enhance the stability of sodium percarbonate bleach in particula te 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 stabilising effect, the crystallin e aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.
