Abstract (en)
In a process for preparing a particulate detergent composition containing an anionic detergent-active compound, for example, an alkylbenzene sulphonic acid, a slurry is prepared by incorporating the anionic detergent-active compound in wholly or predominantly acid form when the slurry already contains at least two equivalents of alkaline material per equivalent of the acid, and the slurry is then spray-dried to form a powder.
