ABSTRACT:
The invention relates to novel essentially anhydrous oily bath and shower compositions containing a combination of fatty oil and/or fatty or waxy apolar substance, oil-soluble surfactant, and vesicle-forming lipid and, if desired, a cosmetically- or balneologically-active ingredient. When poured into or simply admixed with water, these formulations immediately and automatically, generate dispersed vesicles or liposomes. They exhibit an immediate as well as a prolonged or depot effect, can be used alone or added to or together with existing bath or shower formulations, and are especially suited for use in connection with or as additives to full, partial, or shower baths.
