Abstract
A particulate detergent composition having a bulk density of 700 g/l or less and containing at least 10 wt % (preferably at least 15 wt %) of organic detergent surfactant comprises a base powder composed of at least two granular components. Less than 80% by weight, preferably less than 66% by weight, of the base powder has a compressibility (measured at 20-25.degree. C. and about 40% relative humidity) of 17% or more. Preferably one of the components of the base powder is a granule containing a high level (at least 60 wt %) of anionic surfactant.
