Abstract:
A liquid personal cleansing composition comprising:(a) from about 0.01% to about 15% by weight of a thickening system which consists essentially of hydrophobically modified water-soluble associative polymer and polar oil having a required HLB of at least 12 wherein the polar oil is present at a level of from about 0.01% to about 3% and wherein the polar oil is selected from the group consisting of natural primary fatty alcohols and synthetic primary fatty alcohols;(b) from about 0.1% to about 20% by weight of a nonionic polyhydroxy fatty acid amide surfactant having the general formula (II): ##STR12##wherein R.sub.8 is C.sub.5 -C.sub.31 hydrocarbyl, R.sub.9 is hydrogen, C.sub.1 -C.sub.8 alkyl or hydroxyalkyl and Z.sub.2 is a polyhydroxyhydrocarbyl moiety;(c) from about 1% to about 60% by weight of water-soluble auxiliary surfactant other than the polyhydroxy fatty acid amide surfactant of (b), selected from anionic surfactant, nonionic, zwitterionic and amphoteric surfactants and mixtures thereof; and(d) waters,wherein thepolar oil has an average carbon chain length of from about 12 to about 18 carbon atoms and is substantially similar to the average carbon chain length of the combined polyhydroxy fatty acid amide and other surfactants in the water-soluble, non-dilute surfactant matrix.
