Description

  The present invention relates to a makeup remover that contains an ester compound, a volatile oil agent, and water, and more specifically, it is excellent in removal of makeup makeup, has no stickiness, has a refreshing feeling of use, and has a back skin after use. The present invention relates to a makeup remover that suppresses whitening of the skin due to drying of the skin and has an excellent moisturizing feeling.

  Makeup cosmetics are mainly composed of an oily component, a powder component, and an aqueous component in order to produce various sensuality, cosmetic effects, and makeup lasting. A cosmetic remover is a makeup remover. As a prior art, there is a technique of blending low boiling point isoparaffinic hydrocarbon, polyoxyethylene alkyl ether based activator and water as a technique for removing both types of eye makeup cosmetics for oily type and film forming type ( For example, Patent Document 1). Further, in order to enhance the removal effect, a multilayer makeup remover technique (Patent Document 2) in which an aqueous component, an oil component, a water-soluble salt and a powder are blended has been studied.
