Method of making detergent granules comprising an alkyl sulfate, amphoteric surfactant, and inorganic salt mixture

Abstract

A method of making detergent granules, wherein the detergent granules comprise: (i) an alkyl sulfate (AS) having a branched or linear unalkoxylated alkyl group comprising from 6 to 18 carbon atoms; (ii) an amphoteric surfactant; and (iii) a water-soluble inorganic salt, wherein the method comprises the steps in sequence: a) preheating the AS paste at 50~80° C., and then b) adding the water-soluble inorganic salt into the AS paste with agitation at 50~80° C. to form a mixture, and then c) adding the amphoteric surfactant into the mixture at 50~80° C. to form a mixed paste, and then d) drying the mixed paste to form the detergent granules.
