Abstract: Provided is a method for preparing a nanoemulsion, including mixing an oil phase part (A) containing a ceramide or derivative thereof, cholesterol, non-ionic surfactant, phospholipid and a polyol, a perfume part (B) containing a perfume ingredient, non-ionic surfactant and an alcohol, and an aqueous phase part (C) containing the other water-soluble active ingredients. When a nanoemulsion is obtained by the method, it is possible to reduce processing time and cost since a non-ionic surfactant is used without a high-pressure emulsification process, and the obtained nanoemulsion is more stable against a change in temperature than the other solubilized formulations.
