Abstract (en)
[origin: WO9710326A1] A process for preparing high density detergent agglomerates having a density of a least 650 g/l is provided. The process comprises the steps of: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein said surfactant paste includes, by weight of said surfactant paste, from about 0,1 % to about 50 % of a non-aqueous binder, from about 70 % to about 95 % of a detersive surfactant, and the balance water; (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates; and (c) drying said detergent agglomerates so as to form the high density detergent composition. The process may include one or more additional processing steps such as adding a coating agent after the moderate speed mixer/densifier to facilitate and control agglomeration.
