Abstract

Personal cleansing compositions comprise (A) a cleansing phase containing a surfactant and water; and (B) a separate benefit phase containing a hydrophobic material; wherein the cleansing and benefit phases are packaged together and are in physical contact. The two phases are packaged in physical contact and remain separate and stable at ambient conditions for at least 180 days. These compositions and corresponding methods provide improved cosmetics, skin feel, and/or skin benefit efficacy.
