Process for preparing a detergent powder composition comprising forming an alkaline aqueous slurry of at least a surface-active agent, a builder salt and an organic activator for peroxy-compounds, and subjecting said aqueous slurry to a spray-drying operation to form a particulate detergent composition having the organic activator homogeneously distributed therein. The particulate detergent composition may be admixed with an inorganic persalt e.g. sodium perborate, and also with an enzyme, e.g. a proteolytic enzyme.
