Abstract
Abstract Compositions are disclosed for providing non-greasy, cosmetic moisturizing, conditioning and protective barrier effects on skin and hair, and to a rinse-on method for producing these effects. More particularly the compositions comprise oil-in-water emulsions that are adapted to invert to water-in-oil emulsions at the hair or skin surface when they are rubbed into the skin and hair. The compositions a include water, unctrous oleaginous material, water-dispersible, non-toxic polyvalent metal salt having a cation selected from the group consisting of aluminum (III), cerium (III), iron (III), zirconium (IV), aluminum zirconium coordination complexes, and mixtures thereof and sufficient acid or alkali to provide a pH value of about 1.5 to 7.5.
