Patent number: 8298520Abstract: Disclosed is a deodorant particle having a BET specific surface area of 10 m2/g or more that are obtained by copolymerizing a monomer system including a crosslinkable vinyl monomer and a vinyl monomer having a heteroaromatic ring. The deodorant particles may contain a metal ion. Also disclosed is a process of producing the deodorant particles including the step of copolymerizing a monomer system containing a crosslinkable vinyl monomer and a vinyl monomer having a heteroaromatic ring by oil-in-water emulsion polymerization or precipitation polymerization using an organic solvent whose solubility parameter is different from that of the monomers by an absolute difference of 0 to 2.0. The process can further include the step of bringing the particles obtained by the polymerization into contact with a solvent having a metal salt dissolved therein to support a metal ion on the particle.Type: GrantFiled: June 27, 2007Date of Patent: October 30, 2012Assignee: Kao CorporationInventors: Takashi Itoi, Koji Mimura, Daisuke Yamazaki, Masafumi Miyamoto, Tetsuji Kito, Seiichi Miyanaga, Hirohiko Ishida
