  2. Description of the Related Art Conventionally, the type and amount of an oil agent contained in an oil-in-water emulsion composition to impart a moisturizing effect to the skin have been studied. The properties of these oils are also various, such as liquid, paste, and solid. Among them, paste oils at 25 ° C are excellent in moisturizing effect, but give a sticky feeling when applied to skin. You may feel it. For this reason, in order to reduce the sticky feeling on the skin at the time of application, there is a technique for reducing the sticky feeling on the skin by, for example, adding a powder or the like (for example, see Patent Document 1). There is also a technique for reducing the sticky feeling of paste-like oil by adding a liquid oil or a solid oil together (for example, see Patent Document 2). On the other hand, propylene polymers are being studied for application in cosmetics as high melting point resins (for example, see Patent Document 3).
