PROCESS FOR PRODUCING DETERGENT AGGLOMERATES FROM HIGH ACTIVE SURFACTANT PASTES HAVING NON-LINEAR VISCOELASTIC PROPERTIES

摘要

A process for preparing detergent agglomerates for a detergent composition i s provided. The process comprises the steps of: (a) providing a non-linear viscoelastic surfactant paste including, by weight of the surfactant paste, from about 70 % to 95 % of a detersive surfactant and from about 5 % to abou t 30 % of water; (b) regulating the amount of sodium carbonate in the surfacta nt paste such that the surfactant paste has a Maximum Shear Rate of at least 20 sec-1 so that the surfactant paste is processable; (c) charging the surfacta nt paste into a high speed mixer/densifier; (d) inputting from about 1 % to abo ut 70 % by weight of a detergency builder into the high speed mixer/densifier; and (e) agglomerating the surfactant paste and the builder by treating the surfactant paste and the builder initially in the high speed mixer/densifier and subsequently in a moderate speed mixer/densifier so as to form detergent agglomerates.
