ABSTRACT:
A particulate detergent composition having a bulk density of at least 650 g/l which is not the product of a spray-drying process consists of a substantially homogeneous granular base and optional postdosed ingredients. The composition comprises a surfactant system, alkali metal aluminosilicate builder, and a water-soluble salt of citric acid, preferably sodium citrate, and optionally other ingredients. The delivery and dissolution characteristics of the composition in the wash are improved if citrate of Rosin Rammler particle size less than 800 .mu.m is incorporated within the granular base. The composition may also contain postdosed citrate of unrestricted particle size.
