Sulfate free clear personal cleansing composition comprising low inorganic salt

Abstract

A clear personal cleansing composition having an anionic surfactant, a cationic deposition polymer, an aqueous carrier and a level of inorganic salt of from about 0 to about 1 wt %. The composition is substantially free of sulfates and has a % T of greater than about 80%. The composition can further comprise amphoteric surfactants. The composition remains phase stable and minimizes coacervate formulation until after dilution with water.
