Description

[Technical field]

[0001] The present invention relates to a composition that mimics the odor of cat feces. [Background technology]

[0002] In recent years, the pet market in Japan has been expanding. In particular, the number of new cats and dogs being kept has been increasing steadily over the past few years.

[0003] Also, in the medium term, the number of dogs being kept is on the decline, while the number of cats being kept is on the rise. As a result, while the number of cats kept used to be lower than the number of dogs kept, in recent years it has exceeded the number of dogs kept.

[0004] The most bothersome odor when raising a cat is the odor caused by the cat's excrement, so research and development is being conducted to reduce the odor caused by cat excrement.

[0005] For example, Patent Document 1 describes a cat urine treatment device that has a deodorizing effect on the odor caused by cat urine, and Patent Document 2 describes a method for searching for an inhibitor that suppresses the odor caused by cat urine. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2020-110127 A [Patent Document 2] JP 2020-112520 A Summary of the Invention [Problem to be solved by the invention]

[0007] In developing a product that reduces the odor caused by cat excrement, cat excrement is generally prepared, and the extent to which the product reduces the odor is confirmed by sensory evaluation. In this process, the developer is exposed to components other than the odorous components that are derived from cat excrement. These components may contain components that cause allergic symptoms.

[0008] In addition, the odor derived from cat excrement varies between individuals.

Effect of the Invention

[0019] According to the present invention, there is provided a feces imitation odor composition having an odor similar to the odor derived from cat feces. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, embodiments of the present invention will be described. The embodiments described below are more specific embodiments of any of the above aspects. The following items can be incorporated into each of the above aspects alone or in combination.

[0021] 3-Mercapto-3-methyl-1-butanol is a typical sulfur-based malodorous substance that is specifically contained in cat excrement. 3-Mercapto-3-methyl-1-butanol is present in large amounts in the urine of unneutered adult male cats, but the amount is much smaller in the urine of neutered adult male cats and female cats, and is hardly contained in the urine of kittens. And most male cats are neutered before they become adults. Therefore, not many owners are concerned about the smell when cats urinate. In fact, only about 20% of all owners are concerned about the smell when cats urinate. On the other hand, 60% of all owners are concerned about the smell when cats defecate. Therefore, there is a potential demand for reducing the smell caused by cat feces.

[0022] To develop a product that reduces the odor caused by cat feces, as described above in the development of a product that reduces the odor caused by cat excrement, for example, cat feces is prepared, and the extent to which the product reduces the odor emitted by the feces is confirmed by sensory evaluation. In this process, the developer is exposed to components other than the odorous components that are derived from cat feces. The components other than the odorous components may contain components that cause allergic symptoms.

[0023] In addition, the odor derived from feces of cats varies among individuals. Even for the same cat, the odor derived from feces may change depending on the physical condition and type of food. In order to perform the above sensory evaluation accurately and efficiently, it is desirable for the odor derived from cat feces to be consistent.

[0024] Therefore, a fecal odor mimicking composition that has an odor similar to that of cat feces is desired. It is desirable that the odor emitted by this fecal odor mimicking composition is as similar as possible to the odor of cat feces.

[0025] The present inventor has found, through intensive research, that in order to obtain a composition that emits an odor similar to the odor derived from cat feces, that it is extremely important to make the composition contain linalool.That is, no matter how the composition of the pseudo-feces odor composition that does not contain linalool is devised, it cannot realize the odor similar to the odor derived from cat feces to the extent that the pseudo-feces odor composition that contains linalool can realize.

[0062] This artificial feces odor composition can emit an odor similar to that derived from cat feces. In addition, by preparing this artificial feces odor composition by appropriately mixing the above components, it can contain the same components as the odor-causing components contained in cat feces, while eliminating the presence of components other than the odor-causing components contained in cat feces, such as microorganisms. Therefore, this artificial feces odor composition makes it possible to perform sensory evaluation safely and securely, for example, in the development of products that reduce the odor derived from cat excrement. In addition, this artificial feces odor composition makes it possible to perform the above sensory evaluation accurately and efficiently. EXAMPLES

[0063] Tests carried out in relation to the present invention are described below.

[0064] (1) Analysis of odors originating from cat feces The odor composition derived from cat feces was analyzed by the following method.

[0065] Feces were collected from five cats A to E, and the odor composition derived from the feces was analyzed by solid phase microextraction gas chromatography mass spectrometry (SPME-GCMS). Specifically, 0.5 g of feces was first placed in a vial with a volume of 20 mL, and the opening of the vial was sealed with a septum. Next, the lower part of the vial was immersed in a water bath set at 40°C to fill the head space of the vial with odor. Next, the hollow needle of the fiber assembly held in the SPME holder was penetrated into the septum, and then the fiber was protruded from the tip of the hollow needle. After the adsorption of the odor components in the head space by the coating phase provided on the surface of the fiber reached equilibrium, the fiber was drawn into the needle, and then the needle was pulled out from the septum. Thereafter, the needle was introduced into the injector of a gas chromatograph mass spectrometer, and the odor components adsorbed by the coating phase were thermally desorbed, and analysis was performed by the gas chromatograph mass spectrometer.

[0066] The results of the above analysis may depend on the type of fiber. As a result of performing the same analysis using multiple types of fibers, the highest detection accuracy was achieved when using DVB / CAR / PDMS (50 / 30 μm), so DVB / CAR / PDMS (50 / 30 μm) was used here as well.

[0067] The analytical instrument used was a GCMS-QP2020NX manufactured by Shimadzu Corporation, and the column used was an InertCap (registered trademark) Pure-WAX (30 m, 0.25 mm, 0.25 μm) manufactured by GL Sciences.

[0068] The results are shown in Table 1 below. Note that Table 1 only shows the odor components that were common to the feces obtained from three or more cats among the odor components that were detected.

[0069] [Table 1]

[0070] (2) Preparation and evaluation of fecal odor simulants As shown in Table 1, the odor components derived from the feces obtained from cat C (female cat) contain a larger variety of compounds as common components compared to the odor components derived from the feces obtained from other cats. Therefore, based on the composition of the odor components derived from the feces obtained from cat C, recipes for artificial fecal odor compositions were created as shown in Tables 2 and 3 below. Then, according to these recipes, 10 g of artificial fecal odor composition was prepared in each vial with a volume of 20 mL.

[0071] [Table 2]

[0072] [Table 3]

[0073] In Tables 2 and 3, "%" means "% by mass." The values ​​in the column labeled "Fixed and Variable Components" are the percentage of the amount of each component in the total amount of components excluding the solvent (triacetin). The values ​​in the column labeled "Total Components" are the percentage of the total amount of components excluding triacetin in the total amount of all components including triacetin, or the percentage of the amount of triacetin in the total amount of all components including triacetin.

[0074] Next, 0.5 g of cat feces that had been frozen and stored in a 20 mL vial was thawed at room temperature while still sealed in the vial, and was then allowed to stand for an additional hour.

[0075] After that, the cap of the vial containing the feces was opened, and the odor filling the head space was smelled by bringing the nose close to the opening of the vial. Next, the nose was brought close to the opening of the vial containing the artificial feces odor composition, and the odor filling the head space was smelled. Then, the "intensity" and "pleasantness / unpleasantness" of the odor of the artificial feces odor composition, and the "similarity" of the odor of the artificial feces odor composition to the odor derived from feces were evaluated according to the criteria shown in Tables 4 to 6 below.

[0076] [Table 4]

[0077] [Table 5]

[0078] [Table 6]

[0079] The artificial feces odor composition of Example 4 is different from the artificial feces odor composition of Comparative Example 4 only in that it contains linalool. The former odor has a high similarity to the odor derived from cat feces, while the latter odor has almost no similarity to the odor derived from cat feces.From this result, it can be seen that in order to obtain a composition that emits an odor similar to the odor derived from cat feces, it is extremely important to make the composition contain linalool.

[0080] In addition, the pseudo-feces odor compositions of Comparative Example 1 to Comparative Example 4 do not contain linalool, and their odors are almost not similar to the odor derived from cat feces or are slightly similar.In contrast, the pseudo-feces odor compositions of Examples 1 to 5 contain linalool, and their odors are more similar to the odor derived from cat feces.From this result, it can be seen that the pseudo-feces odor composition containing linalool can realize an odor similar to the odor derived from cat feces, while the pseudo-feces odor composition not containing linalool cannot realize an odor similar to the odor derived from cat feces, no matter how the composition is devised.

[0081] (3) Other fecal odor simulating compositions A simulated fecal odor composition was prepared according to the recipe shown in Table 7 below.

[0082] [Table 7]

[0083] In Table 7, "%" means "% by mass." The values ​​in the column labeled "Main Component" are the percentage of the amount of each component in the total amount of components excluding the solvent (triacetin). The values ​​in the column labeled "Total Components" are the percentage of the total amount of components excluding triacetin in the total amount of all components including triacetin, or the percentage of the amount of triacetin in the total amount of all components including triacetin.

[0084] The odor of this artificial feces odor composition was also evaluated for similarity to the odor derived from feces. As a result, the odor of this artificial feces odor composition was also highly similar to the odor derived from cat feces.
