    Abstract: Provided is a sunscreen cosmetic product including a foamed rubber sponge and a cosmetic composition impregnated in the foamed rubber sponge. The cosmetic composition comprises only an inorganic ultraviolet blocking agent as an ultraviolet blocking agent. When the cosmetic composition comprises only an inorganic ultraviolet blocking agent as an ultraviolet blocking agent, it is possible to realize the sunscreen effect of the content wholly even after impregnation, since the inorganic ultraviolet blocking agent is not adsorbed to the foamed rubber sponge but is dispensed with no loss caused by adsorption. It is possible to increase the usage efficiency by controlling the pore size of the foamed rubber sponge during foaming to improve the ratio of the amount that can be used by the consumers based on the amount of the content impregnated in the sponge.

    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.

    Abstract: Provided are a method for preparing cationic liposomes by using a high-pressure emulsification device, cationic liposomes prepared by the method, and a cosmetic composition, a food composition and a pharmaceutical composition, comprising the cationic liposomes. According to the method for preparing cationic liposomes, toxic organic solvents are not employed and thus it is possible to produce liposomes safe for the skin at mass scale by using a high-pressure emulsification device. In addition, the cationic liposomes prepared by the above method have excellent formulation stability, and are positively charged, so that the skin absorption ability of active ingredients loaded therein may be enhanced. Therefore, the cationic liposomes can be used in cosmetics, foods, drugs, and the like.
