Abstract

The deodorant composition of the present invention includes an amorphous aluminum silicate, a hydrazide compound, and a crystalline zinc oxide in which at least two peaks among three peaks detected within a diffraction angle (2θ) range from 30 to 38 degrees when the crystalline zinc oxide is subjected to X-ray powder diffraction measurement have a half width of 0.4 to 1.2 degrees in an X-ray diffraction chart, wherein a content of the crystalline zinc oxide is in a range from 100 to 500 parts by mass based on 100 parts by mass of the hydrazide compound, and wherein a content of the amorphous aluminum silicate is in a range from 100 to 750 parts by mass based on 100 parts by mass of the hydrazide compound.

First claim

The invention claimed is:

1. A deodorant composition, comprising:
an amorphous aluminum silicate;
a hydrazide compound; and
a crystalline zinc oxide in which at least two peaks among three peaks detected within a diffraction angle (2θ) range from 30 to 38 degrees when the crystalline zinc oxide is subjected to an X-ray powder diffraction measurement have a half width of 0.4 to 1.2 degrees in an X-ray diffraction chart;
wherein a content of the crystalline zinc oxide is in a range of from 100 to 500 parts by mass based on 100 parts by mass of the hydrazide compound, and
wherein a content of the amorphous aluminum silicate is in a range of from 100 to 750 parts by mass based on 100 parts by mass of the hydrazide compound.

2. The deodorant composition according to claim 1 ,
wherein the crystalline zinc oxide and the amorphous aluminum silicate have a median particle size of 3 μm or smaller.

3. The deodorant composition according to claim 1
wherein the hydrazide compound is a dihydrazide represented by formula (I),
H 2 NHN—X—NHNH 2   (I)

where X is —CO— or —CO—Y—CO—, and Y is a substituted or unsubstituted divalent hydrocarbon group.

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