ABSTRACT:
A process for continuously preparing low density detergent agglomerates is provided. The process comprises the steps of: (a) spray drying an aqueous mixture of sodium sulfate, sodium carbonate and a minor amount of a surfactant so as to form spray dried granules containing an inorganic double salt having the formula Na.sub.2 SO.sub.4 .multidot.Na.sub.2 CO.sub.3 and a minor amount of the surfactant; (b) agglomerating the spray dried granules with a detergent surfactant paste or precursor thereof and adjunct detergent material initially in a high speed mixer and subsequently in a moderate speed mixer to obtain detergent agglomerates, wherein the adjunct detergent material includes an adjunct sodium carbonate material; and (c) drying or cooling the detergent agglomerates so as to form the detergent composition having a density of below about 500 g/l.
