Description

It relates to a deodorizing composition.

BACKGROUND ART In recent years, various deodorizing products have been known for the purpose of deodorizing living spaces and the like from the viewpoint of obtaining a more comfortable living environment. Water-soluble deodorant ingredients are often used in such deodorant products. In this case, water is mainly used as a solvent, and the deodorizing component is dissolved in water before being used for deodorizing.

However, when the deodorant component is dissolved in a solvent such as water, the deodorant product requires at least the deodorant component and an amount of solvent that enables dissolution of the deodorant component. As a result, the volume of the solvent increases, so the size of the deodorizing product cannot always be reduced.

In addition, while deodorant products such as stationary type, spray type and aerosol type are known, products for the purpose of fragrance (fragrant products) are also known as stationary type, spray type and aerosol type. In recent years, in fragrance products, reed diffuser type products, which are used with reeds (thin sticks, etc.) inserted in a container, are increasing because they are relatively space-saving and have a good design. . However, even if an attempt is made to use a water-soluble deodorizing component in the reed diffuser type, the liquid volume of the solvent increases, making it unsuitable for a space-saving deodorizing product.

On the other hand, today, dimer acids and trimer acids have been reported as oil-soluble deodorant components, and they are known to be useful for deodorizing ammonia and amines (Patent Document 1). In addition, acetic acid is known as one of the main malodorous components, and body odor, garbage, excrement, pets and the like are known as the sources of acetic acid. Therefore, it is important to reduce the odor of acetic acid in living spaces and the like.

It can be sprayed in the space to be smelled, the object to be deodorized, the vicinity thereof, or the like. When the deodorant composition of the present disclosure is used as a wipe-type (deodorant sheet, etc.) product, any cloth such as a conventionally known nonwoven fabric is impregnated with the deodorant composition of the present disclosure. The surface or the like to be deodorized should be wiped off in the state where

The application target of the deodorant composition of the present disclosure is not limited, for example, space (indoor space, car interior space, etc.), curtains, sofas, bedding, cloth products such as clothing, leather products, shoes, walls, floors, ceilings, doors , furniture, pet breeding places, and the like. Although the present disclosure is not limited, the deodorant composition of the present disclosure is preferably applied to indoor spaces such as living rooms, toilets, entrances, shoeboxes, and car interiors, and car interior spaces. Since the component selected from the above (1) to (11) can reduce at least the acetic acid odor, the deodorant composition of the present disclosure can reduce or eliminate the acetic acid odor in or near the application target. can be done.

As described above, acetic acid is known to be one of the main malodorous components, and its sources are known to be body odor, garbage, excrement, pets, and the like. The deodorant composition of the present disclosure, which contains at least one selected from the group consisting of the components (1) to (11) as a deodorant component (deodorant active component), is effective in reducing or removing at least the odor of acetic acid. Useful. Moreover, as shown in the examples below, at least the components (1) to (10) are also effective against isovaleric acid (3-methylbutanoic acid), which is known as one of the main malodorous components. Therefore, the deodorant composition of the present disclosure containing this component is useful for reducing or removing not only acetic acid odor but also isovaleric acid odor.

Further, as described above, unlike the water-soluble deodorant components widely used in conventional deodorant compositions, one component selected from the group consisting of (1) to (11) is Since it is not essential to dissolve in a solvent, the amount of liquid required for deodorization can be reduced, and it can be preferably applied to relatively small (space-saving) deodorant products (volatilizers). can. In addition, since the conventional deodorant component is water-soluble, there is a problem that it is difficult to mix with oil-soluble perfume and it is difficult to use together. makes it possible to easily obtain a uniform liquid mixture even when a perfume is added. In addition, the deodorant composition of the present disclosure has very little influence on the fragrance (fragrance) derived from the perfume, and could be used in combination with the perfume. From this, it can be said that the composition for deodorization of the present disclosure is also useful as a composition for deodorization and fragrance by blending a perfume therein.

In this test example, a total of 12 components shown in Examples 1 to 11 and Comparative Example 1 described later were used as samples. The present inventors have studied various components and paid attention to these components.

Put 50 g of the sample in a glass bottle, insert 8 polyester sticks (18 cm long sticks) into the glass bottle, and hold the tip of the stick in contact with the sample in the glass bottle (with the sample sucked). left overnight.

In the draft chamber, several drops of acetic acid were dropped on the filter paper placed on the metal cap, and the filter paper placed on the metal cap was placed in the airbag. Next, odorless air was introduced into the airbag and left for 30 minutes to obtain an acetic acid masterbatch.

After standing overnight, the glass bottle with the stick inserted was placed in a newly prepared air bag (10 L), and 5 L of odorless air was injected. Next, acetic acid from the acetic acid masterbatch was injected into the airbag so that the concentration was 100 ppm (approximately 40 mL was injected) and the airbag was sealed. Sixty minutes after the injection of acetic acid, the concentration of acetic acid in the airbag was measured using a gas detector tube (trade name: acetic acid detector tube No. 81, manufactured by GASTEC Co., Ltd.). The deodorizing rate of acetic acid was calculated according to the following formula.
Deodorant rate (%) = (initial value - measured value) x 100/initial value initial value: 100 (ppm)
Measured value: Value (ppm) 60 minutes after injection of acetic acid

On the other hand, when each of the components shown in Examples 1 to 11 was used, the deodorization rate of acetic acid odor was 88% or more, which was very high. Each component of Comparative Example 1 and Examples 1 to 11 is common in that it is conventionally known to be usable as a solvent (for example, Comparative Example 1 is an isoparaffinic solvent, Examples 1 to 6 are Glycol ether solvent, Examples 7 to 10 are alcohol solvents). Surprisingly, it was found that each component of Examples 1 to 11 provided a remarkable deodorizing effect. From this, it was found that each component of Examples 1 to 11 is useful as a deodorizing active ingredient in deodorizing the odor of acetic acid.

Test Example 2 (Deodorant Evaluation for Isovaleric Acid)
Test procedure The deodorant effect on isovaleric acid (3-methylbutanoic acid), which is a malodorous component, was evaluated according to the following procedure.

Put 50 g of the sample in a glass bottle, insert 8 polyester sticks (18 cm long sticks) into the glass bottle, and hold the tip of the stick in contact with the sample in the glass bottle (with the sample sucked). left overnight. In this test example, the components shown in Examples 1, 3 to 10 and Comparative Example 1 were used as samples.

In a draft chamber, a few drops of isovaleric acid were dropped on a filter paper placed on a metal cap, and the filter paper placed on the metal cap was placed in an airbag. Then, odorless air was introduced into the airbag and left for 30 minutes to obtain an isovaleric acid masterbatch.

After standing overnight, the glass bottle with the stick inserted was placed in an air bag (10 L), and 5 L of odorless air was injected. Next, isovaleric acid was injected from the isovaleric acid masterbatch to 20 ppm into the airbag (approximately 850 mL was injected) and sealed. Sixty minutes after injection of isovaleric acid, the concentration of isovaleric acid in the airbag was measured using a gas detector tube (trade name: acetic acid detector tube No. 81L, manufactured by GASTEC Co., Ltd.). The deodorizing rate of isovaleric acid was calculated according to the following formula.
Deodorant rate (%) = (initial value - measured value) x 100/initial value Initial value: 20 (ppm)
Measured value: Value (ppm) 60 minutes after injecting isovaleric acid

Results Table 2 shows the results of using each component of Examples 1 and 3 to 10 and the isoparaffinic hydrocarbon of Comparative Example 1.

As shown in Table 2, when the isoparaffinic hydrocarbon of Comparative Example 1 was used, the deodorizing rate of isovaleric acid was 46%. On the other hand, when the components shown in Examples 1 and 3 to 10 were used, the deodorizing rate of isovaleric acid was 83% or more, which was very high. Each component of Comparative Example 1 and Examples 1 and 3 to 10 is common in that it is conventionally known to be usable as a solvent, but surprisingly, each of Examples 1 and 3 to 10 It was found that the ingredients have a remarkable deodorant effect. From this, it was found that each component of Examples 1 and 3 to 10 is useful as a deodorant active ingredient for deodorizing isovaleric acid. In addition, since the component shown in Example 2 is very similar in structure to the component shown in Example 1, from the results, the component of Example 2 also has the same isovaleric acid odor as the component of Example 1. It was understood that a high deodorizing effect against

From these results, it was confirmed that the components of Examples 1 to 10 can exert a high deodorizing effect against isovaleric acid odor. Moreover, from this, it was found that the components of Examples 1 to 10 are also useful as deodorizing active ingredients for deodorizing isovaleric acid.

Test Example 3 (odor intensity evaluation)
Test Procedure A filter paper was placed on a plastic petri dish, 0.5 g of each sample shown in Table 3 was dropped onto the center of the filter paper, and the petri dish was covered. Open the lid 5 minutes after closing the lid, let 9 expert panelists directly smell the odor of the filter paper (the distance between the filter paper and the nose is 5 cm), according to the 6-step odor intensity indication method, based on the following criteria to evaluate the odor intensity of the samples. The 6-step odor intensity display method is a conventionally known evaluation method used to evaluate odors, and is a method of evaluation based on 6-step standards of 0 to 5. In Table 3, blank is the result of smelling the filter paper only (without dripping the sample) in the same way.

0: Odorless 1: Barely detectable odor (detection threshold)
2: A weak odor that makes it possible to identify what it is (cognitive threshold)
3: Easily perceivable odor 4: Strong odor 5: Strong odor

Results The results are shown in Table 3. The values in the table show the average values of all panelists.

As shown in Table 3, the blank (filter paper only (Reference Example 1)) had an odor intensity of 0. Also, in Reference Example 2 in which only water was dropped as a sample, the odor intensity was 0.07. Both Reference Examples 1 and 2 were odorless. Further, the isoparaffinic hydrocarbon of Comparative Example 1 is a component conventionally said to be almost odorless, and its odor intensity was 1.93.

As shown in Table 3, the odor intensity when the component of Example 9 was used was 0.36, which was lower than that of Comparative Example 1. Moreover, the odor intensity when the components of Examples 6 and 7 were used was 2.43 and 2.00, respectively. From these values, it can be said that the odors perceived by humans for the components of Examples 6, 7, and 9 are all comparable to those of Comparative Example 1. Moreover, the odor intensity when the component of Example 1 was used was 2.79, and since the odor intensity exceeded 2 in this way, the odor was perceptible, but not unpleasant. When the components of Examples 3 and 8 were used, the odor intensity was 3.86 and 3.71, respectively. The odor was not unpleasant when volatilized or sprayed into an indoor space. In addition, the odor intensity when the components of Examples 4, 5 and 10 were used was 4.36, 4.00 and 4.21. It didn't smell.

From this, it can be said that even when these components are volatilized or sprayed into an indoor space or the like, they do not have an odor that makes humans feel uncomfortable. In addition, among these components, components with an odor intensity of 3 or less have a very low odor themselves, so even when used in combination with a perfume, for example, it is difficult to interfere with the fragrance derived from the perfume. It has been found to be particularly useful in terms of

Test example 4
Using Examples 6, 7 and 9, in which the odor intensity was 3 or less in Test Example 3 and the odor itself was very low, even when actually combined with a perfume, the fragrance of the perfume was disturbed. In order to confirm whether it is useful as a hard-to-remove ingredient, the following test was conducted. In addition, using the components of Example 3, whose odor intensity was 3.86 in Test Example 3, a test was similarly conducted to determine whether or not the fragrance of the perfume would be less likely to be disturbed.

Specifically, a filter paper was placed on a plastic petri dish, 0.5 g of each sample shown in Table 4 was dropped onto the center of the filter paper, and the petri dish was capped. Five minutes after closing the lid, the lid was opened, and the smell of the filter paper was directly smelled by 9 expert panelists (the distance between the filter paper and the nose was 5 cm). Pleasant and unpleasant odors were evaluated based on The 9-step pleasure/discomfort degree display method is a conventionally known evaluation method used to evaluate the quality of odors, and is a method known as a method of quantifying the pleasantness/unpleasantness of odors. In this test example, -2 for unpleasant, -1 for slightly uncomfortable, 0 for neither pleasant nor unpleasant, 1 for slightly pleasant, and 2 for pleasant (-2 to 2), 9 in increments of 0.5 Pleasant and unpleasant odors were evaluated on a scale.

The samples were perfumes alone, or mixtures of the components shown in Table 4 (Examples 3, 6, 7, and 9) and perfumes (the perfume content in the mixture was 0.05% by mass). It should be noted that the component and the perfume could be mixed easily and uniformly. The perfumes used in this test were a woody perfume, an oriental perfume and a fruity perfume.

Results The results are shown in Table 4. The values in the table show the average values of all panelists.

As shown in Table 4, the values when only perfume was used were 1.07 (woody tone), 0.93 (oriental tone), and 1.14 (fruity tone). In these, desirable aromas derived from each perfume were obtained. In Test Example 3, when the component of Example 9, which had the lowest odor intensity next to water, was combined with perfume, the value was 0.86 for any perfume. Although this value was slightly lower than the perfume alone, the scent was good without giving off an unpleasant odor compared to the perfume alone. From this, it was confirmed that the component of Example 9 does not impair the scent of the perfume even when combined with the perfume.

In addition, the values when the components of Example 7 and perfume were combined were 0.93, 0.29, and 0.43, and there was a tendency for the values to be lower than when the components of Example 9 were used. However, in this case as well, a good scent of each perfume was obtained without feeling unpleasant as compared with the case of using only the perfume. In addition, the values 0.14, 0.21 and 0.00 when the component of Example 6 and the perfume were combined were lower than when the components of Examples 7 and 9 were used. , it was found that the ingredients of Example 6 can also be used in combination with a perfume. When the component of Example 3, which had an odor intensity of 3.86 in Test Example 3, was combined with perfume, the values were -0.18, -0.86, and -0.71, and a slightly unpleasant odor was observed. Admitted. From this, although the components of Example 3 can also be used in combination with perfume, Examples 6, 7 and 9 were superior in evaluation of pleasant and unpleasant odors.

All of these components are useful in deodorizing the odor of acetic acid and further deodorizing isovaleric acid, etc., and unlike conventional water-soluble deodorizing components, they are convenient because they do not require dissolution in a solvent. Although it can be said that it is a deodorizing active ingredient, it was found that it is also possible to use it in combination with perfume. In addition, it was found that the components (1) to (11) should be appropriately selected and used according to the desired fragrance. In addition, it has been found that the components having an odor intensity of 3 or less, such as Example 6, have very little effect on comfort and discomfort, and can be particularly preferably used in combination with fragrances.
