A thickener-rheology modifier system for use in hair care and skin care compositions comprising: where R is H and Ris H, C&#x2013;Calkyl, or &#x2014;CHCOOX; R is &#x2014;COOX and Ris H or &#x2014;CHCOOX; and R is CHand Ris H, C&#x2013;Calkyl or &#x2014;CHCOOX; and X is H or C&#x2013;Calkyl; where Y is H or CHand Z iswhere R is Cto Calkyl; and where R is an alkyl group of 6 to 22 carbon atoms or an alkaryl of 8 to 22 carbon atom, x is an average number of from about 6 to 200, y is an average number of from about 0 to 50 and A is residue of an unsaturated carboxylic acid having the formula: were R' is H, &#x2014;COOH or CHand R&#x2033; is H, CH, &#x2014;COOH or &#x2014;CHCOOH; and Preferably the thickener-rheology modifier system will contain a surfactant and more preferably will contain boric acid.

Thickener-rheology modifier system for personal care compositions

A selected thickener-rheology modifier system comprising the combination of a hydrophobically, modified alkali-soluble thickener and a polysaccharide hydrocolloid or gum or polyalkylene glycol, preferably with a surfactant and more preferably with boric acid is especially useful in personal care compositions such as hair care and skin care compositions.
