The present invention discloses a material for an absorbent article, the material having an organic hydrophobic antimicrobial agent and a hydrophilic non-volatile organic solvent. The material for an absorbent article is preferably manufactured by a method having a step of applying an antimicrobial agent solution to a material for an absorbent article, the antimicrobial agent solution being formed by dissolving an organic hydrophobic antimicrobial agent in a hydrophilic non-volatile organic solvent. The present invention also discloses an absorbent article in which the material for an absorbent article is used. The absorbent article is preferably manufactured by using a method having a step of making an absorbent core contain an antimicrobial agent solution formed by dissolving an organic hydrophobic antimicrobial agent in a hydrophilic non-volatile organic solvent.

Disclosed is a deodorant particle having a BET specific surface area of 10 m/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.
