Granular detergents containing anionic surfactant and ethoxylated surfactant solubility aid

Claim 1

A granular detergent composition comprising: (a) from about 12% to about 20% by weight of an anionic surfactant containing from 0% to about 50% by weight of ethylene oxide selected from the group consisting of alkali metal salts of C 11-13 alkylbenzene sulfonates, C 14-18 alkyl sulfates, C 14-18 alkyl polyethoxy sulfates containing from about 1 to about 4 moles of ethylene oxide and mixtures thereof; (b) from about 5% to about 25% by weight of the anionic surfactant (a) of anionic surfactants of the formula R(OC 2 H 4 ) n OSO 3 - M + wherein R is an alkyl group containing from about 10 to about 18 carbon atoms, n is from about 15 to about 100 and selected such that the surfactant contains from about 50% to about 95% by weight of ethylene oxide, and M is an alkali metal cation; and (c) from about 5% to about 85% by weight of a water-soluble neutral or alkaline salt, or mixtures thereof; said composition prepared by forming an intimate mixture of the anionic surfactant (a) and ethoxylated surfactant (b), forming a sticky paste of said mixture, and then agglomerating said mixture with the water-soluble neutral or alkaline salt.
