NANOEMULSION BASED ON GLYCEROL FATTY ESTERS AND ITS USES IN THE COSMETIC, DERMATOLOGICAL AND / OR OPHTHALMOLOGICAL FIELDS

摘要

The present invention relates to a nanoemulsion whose oil globules have a mean size of less than 100 nm, containing a solid surfactant at a temperature of less than or equal to 45.degree. C., chosen from glycerol esters, and at least one oil having a molecular weight greater than 400, the ratio by weight of the amount of oily phase to the amount of surfactant ranging from 2 to 10. The surfactant used is for example chosen from monostearate, distearate, tristearate and decaglycerol pentastearate, diglyceryl monostearate. and their mixtures. The emulsion obtained is transparent and storage stable. It can contain significant amounts of oil while maintaining good transparency and having good cosmetic properties. The invention also relates to the use of the nanoemulsion according to the 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 the hair, and in the ophthalmic field in eye drops for the treatment of eyes.
