ABSTRACT:
Spray dried beads, having a low bulk density and high in alkali metal carbonate content and useful for post-treatment with additional amounts of nonionic detergent to produce a heavy duty detergent compositon of a bulk density in the range of 0.2 to 0.35 gram per milliliter, are made by admixing a small percentage of alkali metal soap of higher fatty acid with a 40-75% solids content aqueous crutcher mix comprising the alkali metal carbonate and up to about 2% by weight nonionic detergent heating the crutcher mix to 170.degree.-190.degree. F. and spray drying the mixture.
