[ What is claimed as new and is desired to be secured by Letters Patent of the United States is:] [1.] An aqueous, viscoelastic surfactant solution for the cleaning of hair and skin, consisting essentially of(A) from 4 to 25% by weight of an anionic surfactant selected from the group consisting of fatty alcohol sulfates having from 10 to 18 carbon atoms in the alkyl group, fatty alcohol ether sulfates containing from 1 to 5 moles of ethylene oxide/mole and from 10 to 18 carbon atoms in the alkyl group, monoalkylethoxylate sulfosuccinates containing from 1 to 7 moles of ethylene oxide/mole and from 10 to 18 carbon atoms in the alkyl group, paraffinsulfonates having from 12 to 20 carbon atoms in the alkyl group, phosphoric esters of C.sub.10 - to C.sub.18 -fatty alcohols, phosphoric esters of ethoxylated C.sub.10 - to C.sub.18 -fatty alcohols, C.sub.10 - to C.sub.18 -alkyl isethionates, olefinsulfonates having from 10 to 20 carbon atoms in the alkyl or alkylene groups, and mixtures thereof, with a counterion selected from the group consisting of alkali metals, ammonium, mono-, di-, tri-, and tetra-C.sub.1 - to C.sub.3 -alkylammonium, and Mg;(B) from 0 to 10% by weight of a betainic surfactant selected from the group consisting of alkylamido betaines, alkyl betaines, imidazoline betaines, in each case having from 10 to 18 carbon-atoms in the alkyl group, and mixtures thereof;(C) from 0 to 20% by weight of a nonionic surfactant;(D) from 0 to 6% by weight of an electrolyte selected from the group consisting of alkali metal chlorides, ammonium chlorides, magnesium chloride, alkali metal sulfates, alkali metal carboxylates, and mixtures thereof,(E) from 0 to 5% by weight of a water-soluble polymer selected from the group consisting of polysaccharides of the xanthan or guar type, derivatives thereof, cellulose derivatives, polyethylene oxides and polyacrylates; and(F) from 0 to 5% by weight of a further constituent; wherein the sum of the amounts of (A), (B), and (C) is at least 10% by weight and the sum of the amounts of (C), (D), and (E) is between 2 and 20% by weight, in each case based on the total weight of said aqueous solution, and wherein at a temperature between 20 and 40.degree. C. and a pH of from 4 to 8, said solution exhibits a shear modulus, G.sub.0, between 50 and 500 Pa and the conditions for identity of storage modulus, G', and loss modulus, G", are in an angular frequency range between 0.1 and 60 rad.multidot.s.sup.-1, wherein said solution does not contain a fatty acid N-alkylpolyhydroxyamide.
