The nanoemulsion comprises an emulsifying system havingcomponents such as ceteareth-20, ceteareth-12, glyceryl stearate, cetearylalcohol and cetyl palmitate. This composition imparts to the nanoemulsion anopaque coloration, besides providing to the skin inherent properties of thenanoemulsion such as better absorption of the components by the skin,imparting softness, smoothness and moisturizing for 24 hours, and may be addedto products indicated for hair care.
