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 in a first high speed mixer to obtain agglomerates; (b) mixing said agglomerates in a second high speed mixer to obtain built-up agglomerates; and (c) feeding said built-up agglomerates into a fluid bed dryer in which a binder is sprayed via a nozzle having a height of from 25 cm to 60 cm from the distributor plate of said fluid bed dryer such that said built-up agglomerates are dried and agglomerated to form said low detergent agglomerates having a density in a range from 300 g/l to 550 g/l.
