NANOEMULSION CONTAINING AMPHIPHILIC LIPID AND NONIONIC POLYMER AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a thickening system which can thicken and further gelatinize a composition of oil-in-water type nanoemulsion form without affecting the cosmetic characteristics of the composition. SOLUTION: This oil-in-water type nanoemulsion which contains an oil phase dispersed in water layer and whose small oil spheres has a number-average size of <150 nm, characterized by containing at least one oil, at least one amphiphilic lipid, and at least one nonionic polymer containing at least one hydrophobic block and at least one hydrophilic block, and containing the oil in an amount of 1 to10 parts per part of the amphiphilic lipid.
