ABSTRACT:
A process for the preparation of a granular detergent composition or component having a bulk density of at least about 700 g/l up to a bulk density of about 1100 g/l comprising: (a) providing a low density, particulate detergent or component stock comprising an organic surfactant, a water-soluble inorganic salt and, optionally, other materials, the stock having a bulk density of no more than about 600 g/l; (b) subjecting the low density, particulate stock to high-shear agglomeration whereby the particulate stock is subjected to high-shear forces in intimate contact with a liquid consisting essentially of water in an amount and for a time sufficient (1) to fluidize, wet with water, and mechanically mill the stock to a smaller particle size and (2) to partially agglomerate the wetted, milled stock; (c) subjecting the partially agglomerated stock to rotating agglomeration for a time sufficient to produce, when dried, a further agglomerated, granular detergent composition or component having a bulk density of at least about 700 g/l; and (d) drying the further agglomerated detergent composition or component. The product produced by the method is also disclosed.
