Description

The present invention relates to deodorants, and more particularly to deodorizers used for animal malodors.

In recent years, pets such as dogs and cats are often kept indoors, and there is an increasing demand for pet toilets and deodorizers that suppress the odor of pet excrement and maintain a good indoor environment.

Among pets, the odor of cat excrement is unique to cats, and it has been difficult to reduce the odor. It is known that cat urine and other excreta contain 3-mercapto-3-methyl-1-butanol, which is a substance responsible for the odor characteristic of cats. 3-Mercapto-3-methyl-1-butanol is produced by the decomposition of "felinine", a type of amino acid that exists specifically in cats. Felinine is known to be synthesized by a cat-specific enzyme called ``caxin'' found in cat urine.

In addition to 3-mercapto-3-methyl-1-butanol, ammonia, methyl mercaptan, hydrogen sulfide, acetic acid, and isovaleric acid are also known to be odor-causing substances in cat excrement. It was difficult to deodorize all of these.

There is a strong demand for the development of a deodorant that can efficiently eliminate the odor of excrement peculiar to cats.

Conventionally, cat litter has been used to dispose of cat excrement. Cat litter facilitates the disposal of excrement by allowing cats to excrete on it and discarding only the portion covered with excrement. Some cat litter contains deodorizers to deal with the odor of cat excrement.

For example, Patent Document 1 discloses cat litter containing 0.01 to 0.5% by mass of chlorite and using organic matter as the main raw material. This cat litter is described to have a deodorizing effect on ammonia, trimethylamine, and methyl mercaptan. However, this cat litter has not been shown to have a deodorizing effect on 3-mercapto-3-methyl-1-butanol, which is the substance responsible for the odor characteristic of cat excrement.

Japanese Patent Application Publication No. 2022-101027

As mentioned above, cat excrement contains 3-mercapto-3-methyl-1-butanol, which is a substance that causes a characteristic odor. However, conventional cat litter did not have a sufficient deodorizing effect on 3-mercapto-3-methyl-1-butanol.

Therefore, an object of the present invention is to provide a new deodorant having a deodorizing effect on various odor-causing substances including 3-mercapto-3-methyl-1-butanol.

[Example 1: Dry flakes]
As an example of the present invention, dried ginger flakes were prepared. First, 780 kg of cut pieces of golden ginger from Kochi Prefecture (obtained from Sakata Co., Ltd.) were peeled and washed to remove foreign matter and inedible parts. Thereafter, the ginger was cut to a standard thickness of 5 mm for size adjustment, and 684 kg of ginger was obtained before drying. An appropriate amount of this ginger was placed on a tray of a rack dryer and dried at settings of 60°C for 2 hours, 70°C for 2 hours, 65°C for 2 hours, and 60°C for 2 hours to obtain 43 kg of dried flakes.

[Example 2: Dry powder]
As another example of the present invention, a dried ginger powder was prepared. Using 100 kg of the dried flakes obtained in Example 1, the powder was processed into fine powder using a pulverizer, and then particle adjustment and foreign matter were removed to obtain 97.4 kg of dry powder.

[Test Example 1]
Using the dried flakes of Example 1 and the dry powder of Example 2, a test was conducted to see how much bad odors could be eliminated. For malodor, ammonia, acetic acid, isovaleric acid and 3-mercapto-3-methyl-1-butanol were used.

1 g of the dry flakes of Example 1 or 1 g of the dry powder of Example 2 was placed in a 1 L Erlenmeyer flask (test container), and predetermined amounts of ammonia (150 ppm); acetic acid (50 ppm); isovaleric acid (50 ppm) or 3-mercapto were added. -3-Methyl-1-butanol (10 ppm) was sealed and allowed to react for a certain period of time under the sealed conditions. After the reaction, the residual concentration of malodor in the container was measured, and the deodorization rate (%) was calculated.

Table 1 shows the deodorization rates (%) when using the deodorants of Example 1 and Example 2 against the respective malodors of ammonia, acetic acid, isovaleric acid, and 3-mercapto-3-methyl-1-butanol. and shown in FIGS. 1 to 4.

Both the dried flakes of Example 1 and the dry powder of Example 2 showed strong deodorizing effects against ammonia, acetic acid, isovaleric acid, and 3-mercapto-3-methyl-1-butanol.

Even in the form of dried ginger flakes, high deodorizing effects were confirmed against ammonia, acetic acid, isovaleric acid, and 3-mercapto-3-methyl-1-butanol, but in the form of dried ginger powder, Furthermore, a remarkable deodorizing effect was observed.

[Test Example 2]
Dried flakes and dry powder were prepared in the same manner as in Example 1 or 2 using generally commercially available Chinese ginger and domestic ginger. As commercially available domestically produced ginger, a mixed product of large ginger, Sanshu ginger, and golden ginger (obtained from Sakata Co., Ltd.) was used. In the Tyler standard sieve, using an 18 mesh sieve, there are those that pass through the 18 mesh sieve (indicated as 18 mesh or less in the table) and those that do not pass through the 18 mesh sieve (in the table, indicated as 18 mesh or more). ) and the same method as in Test Example 1 was used to determine the deodorization rate when using a deodorant for each of the bad odors of ammonia, acetic acid, isovaleric acid, or 3-mercapto-3-methyl-1-butanol. (%) was evaluated. As a control, ground raw ginger was prepared using the same type of ginger.

The results of the deodorization rate (%) for ammonia using Chinese ginger or domestic ginger are shown in Tables 1-1 and 1-2, respectively.
The results of the deodorization rate (%) for acetic acid using Chinese ginger or domestic ginger are shown in Tables 2-1 and 2-2, respectively.
The results of the deodorization rate (%) for isovaleric acid using Chinese ginger or domestic ginger are shown in Tables 3-1 and 3-2, respectively.
The results of the deodorization rate (%) for 3-mercapto-3-methyl-1-butanol using Chinese ginger or domestic ginger are shown in Tables 4-1 and 4-2, respectively.

As shown in Tables 1-1 to 4-2, regardless of the variety of ginger produced in China or Japan, by using dried ginger, ammonia, acetic acid, isovaleric acid, and 3-mercapto-3 -High deodorizing effects were confirmed for all methyl-1-butanol.

In addition, as shown in Tables 1-1 to 4-2, when ground raw ginger was used as a control, no deodorizing effect was observed against the four types of bad odors mentioned above. On the other hand, when dried ginger was used, a high deodorizing effect was confirmed in either flake or powder form.

Even in the form of dried ginger flakes, a high deodorizing effect was confirmed against ammonia, acetic acid, isovaleric acid, and 3-mercapto-3-methyl-1-butanol, but in the form of dried ginger powder, Furthermore, a remarkable deodorizing effect was observed. The particle size of dried ginger in powder form is not particularly limited, but it was confirmed that it is preferably a particle size that passes through 18 mesh in a Tyler standard sieve (average particle size of 1 mm or less).

The deodorant of the present invention has a deodorizing effect on all of ammonia, acetic acid, isovaleric acid, and 3-mercapto-3-methyl-1-butanol, so it can eliminate bad odors containing one or more of these. It can be suitably used in deodorants and processing materials for treating objects.
