Abstract A nail conditioning composition comprising an aqueous emulsion of sodium lauryl sulfate, urea and hydrolyzed animal protein in the aqueous phase and mineral oil, cholesterol and a lipid in the oil phase, said lipid being cetyl alcohol, cetyl palmitate or a base salt of palmitic or stearic acids. The composition moisturizes and imparts flexibility to the nail and softens the cuticle area.
