ABSTRACT A granular detergent base composition having a bulk density of at least 650 g/litre comprises: an organic surfactant system consisting essentially of fatty acid soap (5-40 wt% on composition), alkoxylated nonionic surfactant (5-35 wt% on composition) and preferably free of nonsoap anionic surfactant; a detergency builder system consisting essentially of alkali metal aluminosilicate (20-60 wt% anhydrous on composition) and an organic sequestrant builder such as alkali metal citrate (2-15 wt% on composition); and optionally various other detergent ingredients such as sodium carbonate, sodium silicate, sodium succinate. The detergent base composition can be prepared by densification of a spray-dried base powder in a high-speed mixer/granulator. It combines good detergency with a lack of environmentally questionable ingredients, and dispenses well in a drum-type washing machine despite the high bulk density.
