Was filled. Then, under conditions of 25 ° C., 2 hours for ethyl acetate and acetaldehyde, 3 hours for ammonia, and 500 μW / cm 2 UV irradiation (3
80 nm). After the ultraviolet irradiation, the concentration of odorous gas remaining in the bag is measured under the condition of 25 ° C. by the Kitagawa type gas detection method (detection tube type gas measuring instrument GV100S, manufactured by Gastec Co., Ltd.) to obtain the initial odor. The difference from the gas concentration was defined as the deodorant concentration. The results are shown in Table 1. With respect to ammonia, 120 ppm was additionally charged 9 times every 30 minutes, and the difference between the total ammonia concentration (1200 ppm) and the odor gas concentration remaining in the bag was taken as the deodorant concentration.

まれていることによるものである。From Table 1, it can be seen that the samples to which the anatase type titanium oxide was added exhibited a strong deodorizing effect in any of the odorous gases of ethyl acetate, acetaldehyde and ammonia, and the effect was compared with the sample without addition. It can be seen that it is remarkable. It should be noted that even a sample containing no anatase-type titanium oxide has a slight deodorizing effect, but this is because the shirasu itself contains a small amount (about 1% by weight) of titanium oxide.

In a 1 liter bag, 0.9 g of the sample was adsorbed with an odorous gas (ethyl acetate, acetaldehyde or ammonia) until it was saturated in advance (ultraviolet ray irradiation was not performed at this time). Then, the odorous gas concentration in the bag was adjusted to a predetermined amount (ethyl acetate: 685 ppm, acetaldehyde: 6
50 ppm, ammonia: 120 ppm), and Example 1
Then, the concentration of the odorous gas remaining in the bag was measured by the same method as in Example 1, and the difference from the initial odorous gas concentration was defined as the deodorant concentration. The results are shown in Table 2.

It should be noted that although the sample without addition of anatase-type titanium oxide has a slight deodorant effect, this is due to the fact that the shirasu itself contains a trace amount of titanium oxide.

用なものとなる。As is apparent from the above description, in the deodorant composition of the present invention, shirasu adsorbs odorous gas and
Due to the action of the photocatalyst existing around the shirasu, ultraviolet rays decompose the odorous gas adsorbed on the shirasu, so that a strong deodorizing action can be exerted and the action lasts semipermanently. Such a deodorant composition is used as a powder that has been crushed and processed, as a part of a material of a processed product used in a living environment, or by sintering the powder to obtain a molded body, It is very useful industrially, such as using them as deodorants.
