Abstract

Detergent powders of high bulk density, containing anionic and nonionic surfactant and builders are prepared by spray-drying a low moisture content slurry containing liquid active surfactants to suspend inorganic solids including selected builders.
A viscosity adjuster may be added to improve processability.
