ABSTRACT:
Particulate detergent compositions which comprise a detergent compound, an alkali metal carbonate detergency builder and finely divided calcium carbonate having a surface area of at least about 5 m.sup.2 /g, are made with improved properties, by using a process in which the calcium carbonate is dispersed in water to which at least some of the detergent compound is added, after which the alkali metal carbonate is added to form a detergent slurry which is then spray-dried to form the detergent composition.
