Abstract

A process for making a granular detergent composition comprising the steps of adding to a detergent powder particles of percarbonate having a mean particle size in the range of from 250 to 900 micrometers and a powdery flow aid containing a partially hydrated crystalline sodium aluminosilicate having a moisture content of less than 15 %, preferably from 5 % to 12 %.
