Non-caking alkyl ether sulfate-containing detergent composition

Claim 1

A granular or powdery detergent composition consisting essentially of from 3 to 25 percent by weight of an ether sulfate surfactant selected from the group consisting of compounds having the formulae ##EQU6## and ##EQU7## and mixtures thereof, wherein R 1 and R 2 , which are the same or different, are hydrogen, alkyl having one to 21 carbon atoms, or alkenyl having one to 21 carbon atoms, provided that the sum of the number of carbon atoms of R 1 plus R 2 is 11 to 21, R 3 is alkyl having 8 to 16 carbon atoms, n is a number from 1 to 10, and M is an alkali metal or an alkaline earth metal, from 10 to 100 percent by weight, based on the weight of said ether sulfate surfactant, of polyethylene glycol having a molecular weight of 2000 to 50000, and the balance is water-soluble, synthetic anionic clothes-washing surfactant, different from said ether sulfate, or water-soluble, synthetic nonionic clothes washing surfactant, or water-soluble alkaline inorganic builder salt, or water-soluble organic builder, or water-soluble neutral salt, or mixtures thereof, said detergent composition having been prepared by mixing the above-named components thereof with water to form a uniform slurry, and then removing water from the slurry to obtain the powdery detergent composition having the polyethylene glycol uniformly distributed on the detergent particles.
