NANOEMULSION BASED ON OXYETHYLATED OR NON-OXYETHYLATED SORBITAN FATS, AND THEIR USES IN COSMETIC, DERMATOLOGICAL, AND / OR OPHTHALMOLOGICAL ENVIRONMENTS.

摘要

Nanoemulsion comprising an oily phase dispersed in an aqueous phase and having oil globules whose average size is less than 100 nm, characterized in that it contains (1) a solid surfactant at a temperature equal to 45 ° C, selected from the esters sorbitan fatty acids and oxyethylenated sorbitan fatty esters, (2) at least one oil having a molecular weight greater than 400 and (3) at least one ionic amphiphilic lipid selected from the group consisting of the alkaline salts of the di-dimethyl diylatyl- phosphate, alkaline salts of cholesterol sulfate, alkaline salts of cholesterol phosphate, lipoamino acids, sodium salts of phosphatidic acid, cationic amphiphilic lipids and alkyl sulfonic derivatives, oscillating the weight ratio of the amount of oily phase to the amount of surfactant between 2 and 10.
