STICK-SHAPED COSMETIC FOR MOISTURE REPLENISHMENT

Abstract

The purpose of the present invention is to provide a stick cosmetic that has a stick shape and a novel function that allows said stick cosmetic to be used to replenish moisture throughout the day. The present invention relates to a stick cosmetic for moisture replenishment, said stick cosmetic comprising: (A) 0.01-50 mass % of a fluid volatile oil component; (B) 10 mass % or more of water; (C) a wax that is capable of gelating the fluid volatile oil component; (D) a silicone elastomer; and (E) a silicone-based surfactant. The cosmetic of the present invention preferably further comprises (F) a moisturizing agent. The cosmetic of the present invention is suitable for use in touching up makeup and has a stick shape that exhibits excellent portability.
