US Patent No. 9,725,678 B2; The Procter & Gamble Company has patented a liquid detergent composition free of cationic surfactant that is comprised of a surfactant system by weight of the composition, wherein the surfactant system comprises alkyl sulphate surfactant with the formula R1O(A)xSO3M, wherein R1 is a C12-C13 alkyl group, A is an ethoxy group; x represents mole percentage of ethoxylation of 0.6; and M is a cation; a co-surfactant that comprises at least 60% by weight of an amphoteric surfactant that is an amine oxide surfactant/alkyldimethylamine oxide surfactant; a nonionic surfactant that is a condensation product of an aliphatic alcohol having an alkyl group containing from 9 to 11 carbon atoms with from 5 to 12 moles of ethylene oxide per mole of alcohol; and water.
The alkyl sulphate surfactant and the co-surfactant are in a weight ratio of about 1:1 and the alkyl sulphate surfactant and the nonionic surfactant are in a weight ratio of about 2.4:1.
The alkyl sulphate surfactant and the co-surfactant are in a weight ratio of about 1:1 and the alkyl sulphate surfactant and the nonionic surfactant are in a weight ratio of about 2.4:1.
