<p>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 stabilising effect, the crystalline aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.</p> |
