ABSTRACT:
A process for preparing a free-flowing high bulk density granular laundry detergent product comprises pre-blending a powder admixture comprising (1) between about 40-90 weight percent of a water soluble detergent builder wherein at least 70 weight percent of the detergent builder is sodium carbonate, and (b) between about 0.5-10 weight percent of alkali metal chloride salt, (2) forming a builder-surfactant powder by blending the step (1) admixture with between about 5-40 weight percent of a detergent active ingredient which is a blend of sulfated ethoxylated alcohols and nonionic ethoxylated alcohols, (3) subjecting the builder-surfactant powder to treatment with water under agglomerating conditions, and (4) drying the detergent composition to provide a free-flowing granular laundry detergent product having a bulk density of at least 650 grams per liter, and in which the detergent granule surfaces are coated with a glossy shell of alkali metal salt crystallites.
