Personal cleansing compositions comprise a cleansing phase comprising a surfactant and water; and a separate, substantially anhydrous benefit phase comprising a hydrophobic skin benefit agent. The cleansing phase and the benefit phase have substantially the same density; wherein the personal cleansing composition is in a form selected from the group consisting of liquid, semi-liquid, cream, lotion, gel, and mixtures thereof. The two phases are packaged in physical contact. These compositions and corresponding methods provide improved cosmetics, skin feel, and/or skin benefit efficacy.

A personal cleansing article according to claim 1, wherein the hydrophobic skin benefit agent represents at least about 50% by weight of the benefit phase. 7. A personal cleansing article according to claim 1, wherein at least 20% by weight of the benefit phase is selected from the group consisting of petrolatum, mineral oil micro-crystalline waxes, paraffins, ozokerite, polyethylene, polybutene, polydecene and perhydrosqualene, dimethicones, cyclomethicones, alkyl siloxanes, polymethylsiloxanes and methylphenylpolysiloxanes, lanolin, lanolin oil, lanolin wax, lanolin alcohols, lanolin fatty acids, isopropyl lanolate, acetylated lanolin, acetylated lanolin alcohols, lanolin alcohol linoleate, lanolin alcohol riconoleate castor oil, soy bean oil, sunflower seed oil, maleated soy bean oil, safflower oil, cotton seed oil, corn oil, walnut oil, peanut oil, olive oil, cod liver oil, almond oil, avocado oil, palm oil and sesame oil, and combinations thereof. 8. A personal cleansing article according to claim 1, wherein the benefit phase comprises a structurant. 9. A personal cleansing article according to claim 8 wherein the structurant is selected from the group consisting of trihydroxystearin, silicas, clays, and polymers. 10. A personal cleansing article according to claim 1 further comprising a cationic deposition polymer. 11. A personal cleansing article according to claim 1 wherein the at least one cleansing phase stripe and the at least one benefit phase stripe form a pattern within the package. 12. A personal cleansing article according to claim 1 wherein said package is transparent.
