A deodorizing agent comprises at least one hydrazine compound selected from a polycarboxylic acid hydrazide having a hydroxyaryl group, a hydrazide of a hydroxyarylalkanecarboxylic acid, a non-acrylic polyhydrazide and an aminourazole compound. The deodorizing agent is useful for efficiently deodorizing an aldehyde odor. The deodorizing agent may further comprise a deodorizing auxiliary (a basic nitrogen-containing compound, a weak acid or a metal salt thereof, a metal compound, an alcohol, a polyphenol, an adsorbent inorganic compound) and may used as a resin composition in combination with a resin. The resin composition may further comprise an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, a gloss-controlling agent, a slip-improving agent, a coloring agent, a filler or the like. Such a composition ensures to inhibit an aldehyde odor efficiently and capture or scavenge an aldehyde certainly, without deteriorating resin properties even when a deodorizing agent is mixed with a polyacetal-series resin or the like. |
