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.

Claims (34)

1. A clear cleansing composition comprising:

about 3 wt % to about 35 wt % of an anionic surfactant;
