A deodorant and antimicrobial composition comprises an oxide or hydroxide of an alkaline earth metal, hydrated silica, and a cationic surfactant. A deodorant and antimicrobial resin composition can be obtained using the deodorant and antimicrobial composition and a thermoplastic resin. This deodorant and antimicrobial resin composition can be molded or otherwise formed.

Deodorant and antimicrobial compositions

A deodorant and antimicrobial dispersion is formed of a deodorant and antimicrobial component, a binder resin and an aqueous or oily liquid medium. The deodorant and antimicrobial component comprises an oxide or hydroxide of an alkaline earth metal, hydrated silica, and a cationic surfactant.

Deodorant and antimicrobial dispersions

A deodorizing resin composition is composed of 99.9-50 parts by weight of a thermoplastic resin and 0.1-50 parts by weight of a deodorizing ingredient. The deodorizing ingredient is a white or substantially colorless deodorizing agent, which may preferably be composed of 10-90 parts by weight of a zinc compound and 90-10 parts by weight of an aliphatic polycarboxylic acid or a salt thereof, an aromatic polycarboxylic acid or a salt thereof, an acidic polymer or a salt thereof, or a sulfate of aluminum. A formed deodorizing article can be obtained by forming or molding the deodorizing resin composition into a desired shape. Formed articles of the deodorizing resin composition of this invention can have desired beautiful colors and are adapted to absorb offensive odors.

Deodorizing resin compositions and formed deodorizing articles

A deodorizing coating formulation is composed of a white or substantially colorless deodorizing agent, a binder resin and a liquid medium. The deodorizing agent may preferably be composed of 10-90 parts by weight of a zinc compound and 90-10 parts by weight of an aliphatic polycarboxylic acid, aromatic polycarboxylic acid, acidic polymer or a sulfate of aluminum, or a salt thereof. A deodorizing sheet can be obtained by coating and/or impregnating a base sheet with the deodorizing coating formulation and then drying the resulting base sheet. The deodorizing sheet can shield a flavor or odor from external flavors or odors while maintaining air permeability, it is suitable for wrapping foods having strong flavors or odors.
