Personal care compositions containing complexing polyelectrolytes

Abstract:

Compositions of the invention contain, in a cosmetically acceptable aqueous medium, a) a cationic polyelectrolyte, b) at least one surfactant; and (c) from about 0.01 to about 1.2 weight percent of an anionic polyelectrolyte, where the weight ratio of the anionic polyelectrolyte to the cationic polyelectrolyte is from about 0.05 to about 1.2, and where the composition exhibits a viscosity change that is below a minimum significant-change-threshold (.DELTA..eta.min) and exhibits no measurable yield stress or increase in yield stress value when compared to a substantially identical composition that does not contain from about 0.01 to about 1.2 weight percent of the anionic polyelectrolyte, at a weight ratio of anionic polyelectrolyte to cationic polyelectrolyte of from about 0.05 to about 1.2.
