Abstract:
A process for preparing a low density detergent composition characterized by the steps of:(a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material having a median particle size in a range from 5 microns to 70 microns in a first high speed mixer to obtain agglomerates having a median particle size of from 100 microns to 250 microns;(b) mixing said detergent agglomerates with a first binder in a high speed mixer to obtain built-up agglomerates having a median particle size in a range of from 140 microns to 350 microns; and(c) feeding said built-up agglomerates into a fluid bed dryer in which built-up agglomerates are agglomerated with a second binder and dried to form detergent agglomerates having a median particle size in a range of from 300 microns to 700 microns and a density in a range from 300 g/l to 550 g/l.
