Embodiment Construction

[0023] Next, the composition for cosmetic instruments of this invention, and the crosslinked product used as the rubber material for cosmetic instruments etc. which crosslinked the composition for cosmetic instruments of this invention are demonstrated in detail. First, the composition for cosmetic devices of this invention contains (A) epichlorohydrin polymer, (B) crosslinking agent, and (C) hydrotalcites. Next, each component which comprises the said composition is demonstrated.

[0024] (A) Epichlorohydrin polymer

[0025] The (A) epichlorohydrin-based polymer used in the cosmetic appliance composition of the present invention has [-CH as a structural unit derived from epichlorohydrin 2 -CH(CH 2 Cl)-O-] ring-opened polymers; in particular, it is a ring-opened polymer of epichlorohydrin, a ring-opened polymer of epichlorohydrin and a monomer capable of copolymerizing with epichlorohydrin; As epichlorohydrin and monomers that can be copolymerized with epichlorohydrin, stru...

Abstract

The present invention provides a composition for beauty appliances comprising (A) an epichlorohydrin-based polymer, (B) a crosslinking agent, and (C) hydrotalcites. The (B) cross-linking agent is preferably at least one selected from the group consisting of quinoxaline-based cross-linking agents, thiourea-based cross-linking agents, and triazine-based cross-linking agents. Moreover, it is preferable that the molar ratio of the polymerized unit derived from epichlorohydrin in the said (A) epichlorohydrin-type polymer is 60 mol% or more. Moreover, it is preferable to contain 1 to 20 weight part of said (C) hydrotalcites with respect to 100 weight part of said (A) epichlorohydrin-type polymers.

Description

technical field [0001] The present invention relates to a composition containing an epichlorohydrin-based polymer used for hair removal devices, razors such as electric shavers, facial massage rollers (Faceroller), and facial beauty devices, and to making the composition A cross-linked product formed by cross-linking. Hereinafter, the material composed of the above-mentioned cross-linked product may be referred to as "rubber material" or "cross-linked rubber material". Background technique [0002] Hair removers, razors such as electric shavers, face rollers, facial beauty devices and other beauty devices are devices that come into contact with the skin, and materials that are excellent in tolerance to sebum are required. [0003] Sebaceous glands that secrete sebum are distributed throughout the body, but the face has more sebaceous glands than body parts such as hands and feet. Therefore, it can be said that there is more sebum on the face. In addition, it is well known...
