Preparation of low density detergent agglomerates containing silica

摘要

A process for continuously preparing low density detergent agglomerate is provided. The process comprises the steps of: (a) agglomerating a liquid acid precursor of a detergent surfactant and dry starting detergent material in a high speed mixer to obtain detergent agglomerates, wherein the dry starting detergent material includes a silica material and an alkaline inorganic material; and (b) drying the detergent agglomerates so as to form the detergent composition having a density of less than about 500 g/l.
