摘要
The present invention relates to an oil-in-water emulsion for cosmetic use, wherein the oil particles have an average diameter ranging from 50 to 200 nm (nanometers). The nanoemulsion comprises an emulsifying system having components such as ceteareth-20, ceteareth-12, glyceryl stearate, cetearyl alcohol and cetyl palmitate. This composition imparts to the nanoemulsion an opaque coloration, besides providing to the skin inherent properties of the nanoemulsion such as better absorption of the components by the skin, imparting softness, smoothness and moisturizing for 24 hours, and may be added to products indicated for hair care. The composition of the nanoemulsion without addition of preservatives imparts a bactericidal action. The nanoemulsion is preferably used for cosmetic applications 5 for the body, face and hair in the form of milk, lotions and gels. The present invention further relates to the cosmetic compositions and cosmetic products that comprise the nanoemulsions above, as well as to a process for preparing them.
