Abstract
Detergent compositions are prepared containing a carboxymethyloxysuccinate salt detergency builder by spray drying a slurry containing dispersed carboxymethyloxysuccinate salt and detergent compound, to which slurry an alkali metal silicate is added after the addition of the carboxymethyloxysuccinate salt, with the slurry water content being maintained at not less than 40% of the final slurry formulation and a slurry temperature of not less than 76.degree. C. This decreases the formation of insoluble lumps in the slurry and gives improved slurry viscosity control.
