Abstract: This invention comprehends a nanoemulsion based on an emulsifier ternary system that is stable under different temperature and physical stress conditions, besides being compatible with a great variety of cosmetics ingredients. The production method thereof comprises cold emulsification and homogenization steps, which make possible the incorporation of active oily ingredients sensitive to higher temperatures. The obtainment of the nanoemulsion with the properties of this invention comprehends the use of lecithin, of a fatty acid ester and sorbitol condensed with ethylene oxide and a ester of fatty acid and sugar, in specific proportions, as emulsifiers. Such nanoemulsion can be used in cosmetic and dermatological compositions aimed for care, protection and makeup of skin, mucosa, scalp and hair.
