Abstract
A process for continuously preparing low density detergent agglomerates having a density of below about 500 g/l is provided. The process comprises the steps of: (a) agglomerating a detergent surfactant paste or liquid acid precursor of anionic surfactant and dry starting detergent material in a high speed mixer to obtain detergent agglomerates, wherein the dry starting detergent material includes an inorganic double salt and sodium carbonate in a weight ratio of from about 1:10 to about 10:1; and (b) drying the detergent agglomerates so as to form the low density detergent composition having a density below about 600 g/l.
