Abstract
Abstract Skin cleaning agents comprising (A) a continuous oil phase consisting essentially of straight or branched paraffinic oils of 10 to 30 carbon atoms in the chain, (B) a dispersed aqueous emulsified phase, (C) a buffer consisting essentially of lactic acid and triethanolamine for maintaining the normal pH of the outer skin tissue layers, (D) an emulsifying system consisting essentially of mono- and diglycerides of higher natural fatty acids and ethoxylated glycerine esterified with fatty acids of the formula <IMAGE> wherein n is a number between 20 to 45, and preferably between 30 and 35, the Rs are individually a saturated or unsaturated fatty acid residue derived from animal or vegetable oils such as palmitic acid, lauric acid, oleic acid or linoleic acid, (E) -glycerine and (F) - caraghenates optionally modified by esterification of the sulfonic acid residues with lower alcohols.
