Abstract:
A particulate detergent composition having a bulk density of 700 g/l or less and comprising at least 10 wt % of organic detergent surfactant, the composition comprising a base powder which contains detergency builder and organic detergent surfactant selected from the group consisting of anionic surfactants, nonionic surfactants and mixtures thereof and which consists of structured particles, characterized in that the base powder is composed of at least two different granular components, including:(a) at least one granular component having an anionic surfactant content of 60 wt % or more, and(b) at least one granular component containing at least 70 wt % of builder material which is sodium tripolyphosphate and/or zeolite, and less than 5 wt % detergent surfactant,at least one of these granular components having a compressibility, measured at 20-25.degree.C. and about 40% relative humidity, of less than 17%, whereby less than 80 wt % of the total base powder is constituted by a granular component or components having a compressibility of 17% or more.
