Title:
DEODORANT PARTICLE
Document Type and Number:
WIPO Patent Application WO/2008/007557
Kind Code:
A1
Abstract:
Disclosed is a deodorant particle which is produced by the copolymerization
of a monomer component comprising a crosslinkable vinyl monomer and a vinyl monomer
having a heteroaromatic ring, and which has a BET specific surface area of 10 m2/g
or greater. The deodorant particle may further comprise a metal ion. Also disclosed
is a process for producing a deodorant particle, comprising the step of conducting
the oil-in-water-type suspension polymerization or precipitation polymerization
of a monomer component comprising a crosslinkable vinyl monomer and a vinyl monomer
having a heteroaromatic ring by using an organic solvent having an absolute value
of the difference in solubility parameter between the monomer component and
the organic solvent of 0 to 2.0. The method may further comprise the step of contacting
a particle produced by the polymerization with a solvent containing a metal salt
dissolved therein to thereby carry a metal ion on the particle.
