PROBLEM TO BE SOLVED: To solve problems in the case of resins such as candelilla resins and resin acid derivatives, and polymer liquidity hydrocarbons such as heavy isoparaffin and polybutene, which are oil-soluble raw materials conventionally used to improve cosmetic effects, since they are strongly sticky, they provide bad feeling and cause restrictions on blending amounts, and since they have bad extensibility (spreading) on the skin, sufficient cosmetic sustaining effects cannot be obtained; in the case of hydrocarbon waxes and vegetable and animal waxes, since they are solidified during normal temperatures, and amounts used are significantly restricted in liquid prescription, sufficient effects cannot be obtained, and since they provide greasy use feeling, sense of touch is deteriorated.SOLUTION: A cosmetic is obtained by blending copolymers obtained by polymerizing three sorts of monomers, that is, acrylic acid, methacrylate isobornyl and methacrylate isobutyl, which are oil-soluble resins.SELECTED DRAWING: None |
