Abstract
A soap powder having a bulk density of at least 600 g/liter contains 35-80 wt % of organic detergent-active material, of which 70-100 wt % is fatty acid soap of low (.ltoreq.20.degree. C.) Krafft temperature, and 20-65 wt % of inorganic and/or builder salts, and may be prepared by granulation and densification in a high-speed mixer/granulator. The high bulk density soap powder shows improved powder properties and better wetting and dispersion behavior in the wash than corresponding undensified powder.
