Abstract
A particulate detergent composition is prepared by spray drying a slurry containing a surfactant system, which may contain anionic surfactants, nonionic surfactants and/or soap, a non-phosphate builder such as an aluminosilicate or an alkalimetal carbonate and a sugar such as sucrose or sorbitol. The sugar provides the powders with adequate structure without the necessity to utilize sodium silicate.
