るを得なかった。2. Description of the Related Art Conventionally, as a deodorizing material for human and animal excrement, there is a deodorizing material disclosed in Japanese Patent No. 1642383. This deodorizing material is obtained by impregnating ferrous sulfate into a fibrous material and oxidizing the ferrous sulfate to basic ferric sulfate. It is intended and has a considerable effect on the deodorization of the excrement. However, the excretion and other malodorous components are reduced to an odorless state below the olfactory threshold (concentration value ppm at which humans can sense odor). In order to decompose, an extremely large amount had to be required.

A second deodorizing material (B) containing pulp formed in a lump and containing a basic substance is mixed with a deodorizing material (B) in an inner layer on feces and putrefactive garbage which are malodorous substances at a weight ratio of 7: 3. In the same manner, when (A) was covered as an outer layer and the residual odor component was measured using a gas tech detector, the odor components of mercaptans and hydrogen sulfide were almost completely decomposed. Almost no odor was found, no functional odor was found, and no odor was found. On the other hand, when the above results were compared, the odor before the treatment of the offensive odor substance and the residual odor when deodorized using only the first deodorizing material (A) were as shown in Table 1. Such a result was obtained because the deodorizing material of the present invention added the deodorizing effect by the chemical neutralization reaction of the deodorizing material (B) to the chemical deodorizing effect of the deodorizing material (A).

が優れた脱臭効果を得られることが確認された。There are many types of odors in general households, such as odors generated from toilets, garbage, and clogs, body odors of humans and pets, and odors at the time of meals. , Ammonia, amines, mercaptans, hydrogen sulfide, aldehydes and indoles. The point of the presence or absence of the deodorizing effect is how to remove the above-mentioned odor components.
Among the odors, a particularly typical odor is the odor emitted from the toilet. Therefore, a deodorization test was performed on the odor of the toilet as described above. In this test, the deodorizing material (A) was able to obtain an excellent effect on the odor caused by ammonia and amines. It was confirmed that the deodorizing material (B) can obtain a better deodorizing effect for deodorizing odors caused by mercaptan and hydrogen sulfide.
