ABSTRACT:
An improved skin cleansing-conditioning bar consisting essentially of, by weight, 14% to 18% of an anionic surfactant material selected from the group consisting of a sodium or potassium salt of a C-12-C-18 saturated monocarboxylic acid and mixtures of said monocarboxylate salt with a water-soluble, non-soap, anionic detergent selected from the group consisting of sodium and potassium salts higher acyl isethionates, higher alkyl sulfates, higher alkyl sulfonates, higher alkyl monoglyceride sulfates, higher alkylbenzene sulfonates, higher alkyl ethenoxy ether sulfates and mixtures thereof in a weight ratio of said monocarboxylate salt to said detergent of 18:1 to about 2.5:1; about 40% to 72% of a water-insoluble emollient selected from the group consisting of a C-14-C-18 alkanol and mixtures of said alkanol with a C-14-C-18 alkanoic acid wherein the weight ratio of alkanol to alkanoic acid is in the range of about 23:1 to about 0.6:1; the weight ratio of emollient material to said surfactant material being from about 5:1 to about 1.3:1; 0% to 25% of a starch-derived filler; and 2% to 12% of water; said bar having a pH in the range of 6 to 9.5 measured as a 1% by weight aqueous solution and yielding a satisfactory volume of a non-foaming, cleansing-conditioning cream of moderate viscosity when the wetted bar is rotated and manipulated between the wetted hands of the user. Included in the invention is the method of cleansing and conditioning the skin comprising the steps of forming a cream by rotating and manipulating the inventive bar between the wetted hands, applying the cream to the skin, massaging the cream into the skin and rinsing the cream-treated skin with water.
