A process for producing a high density detergent composition having a density of about 650 g/l is provided. The process comprises the step of forming detergent agglomerates by feeding several streams of materials into a mixer/densfier. Specifically, the following materials are continuously fed into the mixer/densifier: (i) from about 1% to about 50% by weight of a C10-18 linear alkylbenzene sulfonate surfactant; (ii) from about 1% to about 50% by weight of a C12-16 alkyl sulfate surfactant, wherein the linear alkylbenzene sulfonate and the alkyl sulfate are in the form of dry particles; (iii) from about 20% to about 50% by weight of a builder; and (iv) from about 0.1% to about 35% by weight of an agglomerating agent which substantially prevents the intimate mixing of the linear alkylbenzene sulfonate surfactant and the alkyl sulfate surfactant in the mixer/densifier. Another step of the process entails drying the detergent agglomerates to form the high density detergent composition having a density of 650 g/l. |
