The present invention relates to a nanoemulsion whose oil globulesnhave an average size less than 100 nm, containing an anionic surfactantnchosen from fatty esters of phosphoric acid and their oxyethylenated derivatives, andnat least one oil having a molecular weight greater than 400, the rationweight of the amount of oily phase over the amount of surfactant ranging from 2 ton10.n n n The anionic surfactant used is for example chosen from potassium saltnalkyl-C9-15-phosphate, esters of stearyl / isostearyl alcohol and acidnphosphoric, esters of cetyl alcohol and phosphoric acid, estersntridecylic alcohol and phosphoric acid, the oxyethylenated derivatives of thesenesters and mixtures thereof.n n n The emulsion obtained is transparent and stable on storage. It may containnlarge quantities of oil while maintaining good transparency andnhaving good cosmetic properties. It can constitute a composition tontopical use, a pharmaceutical composition or a compositionnophthalmic.n n n The invention also relates to the use of the nanoemulsion according to the inventionnin the cosmetic and dermatological fields, in particular for hydrationnof the skin and / or mucous membranes, as well as for the treatment of hair, andnin the ophthalmological field, eye drops for the treatment of the eyes. |
