"NANOEMULSION, COMPOSITION FOR TOPICAL USE, OPHTHALMIC SUPPORT, PHARMACEUTICAL COMPOSITION, COSMETIC USE OF NANOEMULSION, COSMETIC PROCESS OF HOSPITALIZATION AND / OR HYDRATION, ANYTHING OF USAGE AND A HOSPITAL HOSPITAL USE. oil have an average size of less than 100 nm, which contains a surfactant chosen from alkoxylated alkenyl succinates, alkoxylated alkenyl succinates and alkoxylated methyl alkenyl succinates, and at least one oil with a molecular weight greater than 400, of which the weight ratio of the amount of oily phase to the amount of surfactant varies from 2 to 10. The surfactant used is chosen for example in the group comprising hexadecenyl succinate 18 OE, hexadecenyl succinate 45 OE, dihexadecenyl succinate 18 OE , glucose 10 OE dihexadecenyl succinate, glucose 20 OE dihexadecenyl succinate, succin hexadecenyl succinate of glucose 18 OE, dioctadecenyl succinate of methyl glucose 20 OE and mixtures thereof. The emulsion obtained is transparent and stable during storage. It can contain high amounts of oil, while maintaining good transparency and having good cosmetic properties. It can be a composition for topical use, a pharmaceutical composition or an ophthalmic composition. The present invention also deals with the use of nanoemulsion according to the present invention in the cosmetic and dermatological fields, in particular for the hydration of the skin and / or mucous membranes, as well as for the treatment of hair, and in the ophthalmological field as eye drops for the treatment of eyes.
