  A polyacetal resin composition comprises a polyacetal resin having a trioxane content of not more than 100 ppm (preferably not more than 50 ppm, and more preferably not more than 10 ppm) and at least one stabilizer selected from the group consisting of an antioxidant, a formaldehyde emission inhibitor, a processing stabilizer and a heat stabilizer. The polyacetal resin may be a polyacetal resin (particularly a polyacetal copolymer) in which the trioxane amount is reduced by a solvent treatment and/or a heat treatment. Moreover, the polyacetal resin composition may further contain at least one additive selected from the group consisting of a weather (light)-resistant stabilizer, an impact resistance improver, a gloss control agent, a sliding improver, a coloring agent, and a filler. Such a polyacetal resin composition can reduce the amount of trioxane elution and/or the amount of a volatile organic compound from a molded product thereof.

  An aldehyde-inhibiting composition inhibiting an aldehyde from an aldehyde-generating source comprises a carboxylic acid hydrazide and a metal salt of a hydroxy polycarboxylic acid (e.g., a salt of citric acid, malic acid, or tartaric acid with an alkaline earth metal) in a proportion of 0.01 to 100 parts by weight relative to 1 part by weight of the carboxylic acid hydrazide. Moreover, a polyacetal resin composition may comprise a polyacetal resin and the aldehyde-inhibiting composition in a proportion of 0.001 to 20 parts by weight of the aldehyde-inhibiting composition relative to 100 parts by weight of the polyacetal resin. To the resin composition, may be added an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a gloss control agent, a sliding improver, a coloring agent, a filler, and others. A small amount of the aldehyde-inhibiting composition efficiently inhibits the aldehyde generation from the polyacetal resin without discoloring the resin.
