NANOEMULSION BASED ON ETOXYLATED FATTY ETHERS OR ETHOXYLED FATS, AND ITS 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 in number was less than 100 nm, characterized in that it contains a solid surfactant at a temperature less than or equal to 45 C, chosen from the formed ethers from 1 to 100 units of ethylene oxide and at least one chain of fatty alcohol having from 16 to 22 carbon atoms and esters formed from 1 to 100 units of ethylene oxide and at least one chain chosen from the stearate units , behenate, arachididate, palmitate and mixtures thereof, and at least one oil having a molecular weight greater than 400, and because the weight ratio of the amount of oily phase (total amount of the constituents of this phase without including the amount of surfactant) on the amount of surfactant ranges from 2 to 10.
