Abstract

The deodorant of the present invention is characterized in that the deodorant consists of a crystalline zinc oxide in which zinc oxide and aluminum oxide are composited, and a molar ratio (ZnO/Al 2 O 3 ) of the zinc oxide to the aluminum oxide is in a range from 40 to 80. The deodorant has a high deodorizing effect against sulfur gases and acidic gases. A preferable average particle size of the deodorant is 0.2 to 15 μm.

First claim

1 : A deodorant, consisting of:
a crystalline zinc oxide in which zinc oxide and aluminum oxide are composited, wherein a molar ratio of zinc oxide to aluminum oxide is in a range of from 40 to 80.

2 : The deodorant according to claim 1 , wherein the crystalline zinc oxide has an average particle size of 0.2 to 15 μm.

3 : The deodorant according to claim 1 , wherein
the crystalline zinc oxide has a BET specific surface area of 100 m 2 /g or more.

4 : A deodorizing product, comprising the deodorant according to claim 1 .

5 : The deodorant according to claim 1 , wherein
the crystalline zinc oxide subjected to an X-ray powder diffraction analysis has diffraction peaks within a range in which a diffraction angle 2θ is from 30 to 38 degrees, and a half width of each of the diffraction peaks ranges from 0.5 to 1.1 degrees.

6 : The deodorizing product according to claim 4 , which is a deodorizing fiber, wherein
the deodorizing fiber further comprises a fiber, and the deodorant either is embedded in the fiber or adheres to or is bonded to a surface of the fiber.

7 : The deodorizing product according to claim 6 , wherein
the fiber is formed from a resin, and a content of the deodorant is from 0.1 to 20 parts by mass based on 100 parts by mass of the resin forming the fiber.

8 : The deodorizing product according to claim 4 , which is a deodorant-containing coating composition, wherein a content of the deodorant is from 0.1 to 20% by mass based on a total mass of the composition.

9 : The deodorizing product according to claim 4 , which is a deodorizing sheet.

10 : The deodorizing product according to claim 4 , which is a deodorant-containing resin composition comprising a thermoplastic resin, the deodorant, and optionally at least one additive selected from the group consisting of a pigment, a dye, an antioxidant, a light stabilizer, an antistatic agent, a blowing agent, an impact modifier, glass fibers, a dampproof agent, and an extender.
