A composite material of the invention is a mixture of cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g and a moldable polymeric material selected from the group consisting of a biomass-derived polymer and a petroleum-derived polymer. The biomass-derived polymer is preferably polylactic acid or pulp. The cellulose microfibers are preferably present in an amount of 0.01% to 60% by mass. Another composite material of the invention is a mixture of cellulose composite microfibers and a moldable resin, the cellulose composite microfibers being obtained by adsorbing a surfactant onto cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g.

Composite material

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.

Deodorant particle

The invention relates to a cosmetic preparation containing a crosslinked (meth) acrylic acid ester resin powder having a compression strength of 0.7 to 10 kgf/mm. The invention also relates to a cosmetic preparation, for example, in the form of a cosmetic sheet, powder spray cosmetic, gel cosmetic, two phase separable cosmetic, emulsion cosmetic or the like.

Cosmetic preparation

The invention relates to crosslinked (meth)acrylate-based resin particles having an average particle diameter of 1 to 10 &#x3bc;m, containing monomer components containing a monomer having a carboxyl group and at least one monomer selected from an acrylate and a methacrylate copolymerized therein, the particles having a surface coated with a surfactant having a sulfonic acid group or a sulfonate group, and a process for producing the same.
