Title: Use of charged amphiphilic statistic polymers for thickening phase comprising giant micelles of surfactants and aqueous composition comprising same

Abstract: The invention concerns the use as thickening agent of an aqueous composition comprising at least 5 wt. % of one or several phase-organized surfactant(s) comprising giant micelles whereof the average length represents at least four times the mean diameter, of at least a charged statistic amphiphilic polymer soluble in the aqueous composition, said amphiphilic polymer being used in a content such that the viscosity of the aqueous composition comprising the amphiphilic polymer is at least three times higher than that of the composition without amphiphilic polymer and than that of an aqueous composition comprising only the amphiphilic polymer. The invention also concerns aqueous compositions comprising said amphiphilic polymer, and are particularly designed for cosmetic uses.
