A process for preparing detergent agglomerates for a detergent composition is 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 about 30% of water; (b) regulating the amount of sodium carbonate in the surfactant paste such that the surfactant paste has a Maximum Shear Rate of at least 20 sec.sup.-1 so that the surfactant paste is processable; (c) charging the surfactant paste into a high speed mixer/densifier; (d) inputting from about 1% to about 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.
