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.

Abstract: Oily cosmetic composition acting as a lubricant, moisturizer and skin protector, mucosas and hair, being further in condition to act as a basis for decorative or fragrant cosmetics. This composition is exhibited in the form of oil-gel, which may be transparent, translucent or opaque, and exhibits as a different aspect an excellent suspensory capacity, combined with an easy application, good sliding on the skin and a pleasant and silky sensorial after the application. This set of features is obtained through the association of a block copolymer, composed of styrene-ethylene/propylene with silica, on an oily basis. The composition may contain particles in suspension, with decorative and/or functional properties.
