A process is provided for the production of detergent compositions in particulate or powder form containing anionic and nonionic active-detergent materials, which process comprises forming at least two aqueous slurries A and B of detergent ingredients. Slurry A containing an active-detergent component comprising 60-100% by weight of anionic detergents and 0-40% by weight of nonionic detergents, slurry B containing an active-detergent component comprising 0-40% by weight of anionic detergents and 60-100% by weight of nonionic detergents, which slurries are treated as separate streams in a spray-drying equipment, after which the dried products are collected to form a homogeneous mixture of particulate materials comprising the detergent composition.
