Patent ID: 8828364

Claim:
A structured surfactant composition, comprising, based on 100 parts by weight of said composition: (i) from about 0.5 to about 10 parts by weight of an alkyl ether sulfate surfactant comprising one or more compounds according to structure (I): R 1 —O—(C m H 2m O) n —SO 3 − X + (I) wherein R 1 is tridecyl, m is 2 or 3, n is an integer of from 1 to about 5 and X + is a cation, (ii) from about 1.5 to about 12 parts by weight of an alkyl sulfate surfactant comprising one or more compounds according to structure (II): R 2 —O—SO 3 − X + (II) wherein: R 2 is (C 8 -C 18 )alkyl, and X + is a cation, (iii) from about 0.5 to about 6 parts by weight of an alkanolamide surfactant comprising one or more compounds according to structure (III): wherein: R 3 is (C 5 -C 24 ) saturated or unsaturated, straight chain or branched aliphatic group, R 4 and R5 are the same or different, C 2 -C 4 straight chain or branched aliphatic groups, x is an integer from 0 to 10, y is an integer from 1 to 10, and the sum of x and y is less than or equal to 10, and (iv) from 0 to about 8 parts by weight of an amphoteric surfactant comprising one or more compounds selected from compounds according to structures (IV) and (V): wherein: R 6 is (C 1 -C 18 )aliphatic, p is 2 or 3, and R 7 is (C 1 -C 18 )aliphatic, p′ is 2 or 3, and each X+ is independently a cation, provided that the total amount of components (i), (ii), (iii), and (iv) is greater than or equal to 5 parts by weight of the composition, (v) an amount of electrolyte effective to, in combination with components (i), (ii), (iii), and (iv) and in the absence of a polymer thickener, provide a liquid crystalline structured surfactant composition having an opaque visual appearance and exhibiting a yield strength of greater than 0 Pascals, and (vi) water.
