Abstract:
A nanoemulsion comprising:an oily phase dispersed in an aqueous phase and having oil globules with a number-average size of less than 100 nm, a surfactant which is solid at a temperature of less than or equal to 45Â° C., wherein the surfactant is selected from the group consisting of sorbitan fatty esters and oxyethylenated sorbitan fatty esters, at least one oil having a molecular weight of greater than 400, and at least one ionic amphiphilic lipid selected from the group consisting of the alkaline salts of dicetyl and dimyristyl phosphate, the alkaline salts of cholesterol sulphate, the alkaline salts of cholesterol phosphate, lipoamino acids, the sodium salts of phosphatidic acid, cationic amphiphilic lipids and alkylsulphonic compounds, wherein the ratio by weight of the amount of oily phase to the amount of surfactant is 2 to 10.
