  • Publication number: 20190070096
    Abstract: Provided is a follower composition for a cosmetic applicator contributing to stable discharge, excellent holding property for aging stability, and easy to find the end of a liquid cosmetic regardless of any visibility of filling chamber and any type of coating part. The follower composition for a cosmetic applicator is characterized by comprising at least a base oil and 3.5 to 8% by mass of a styrene copolymer elastomer. The follower composition for a cosmetic applicator is used as a follower which is brought into contact with a liquid cosmetic and which moves following the liquid cosmetic reduced as it is consumed in a cosmetic applicator comprising, for example, a cylindrical filling chamber, communicating directly or via an interposition member with a coating part to receive the liquid cosmetic directly.

  • Patent number: 9872550
    Abstract: To provide an applicator with an application body that is nonabsorbent and can uniformly spread and apply an application liquid over the surface to be applied on without scraping the applied liquid during application. The application body includes a membranous part that is easily deformable in applying liquid, and a cavity part enclosed by the membranous part, and constructed such that when the applying surface of the membranous part comes into contact with the surface to be applied on, the contact surface of the membranous part fits closely following the surface to be applied on by the pressure of the membranous part acting onto the contact surface of the surface to be applied on.
