Description

Technical Field

[0001] The present invention relates to a pest control product for killing and / or repelling pests. Background Art

[0002] Conventionally, pest control treatments have been carried out using pest control products such as aerosols containing pest control ingredients in order to kill and / or repel (control) pests such as crawling pests such as cockroaches and flying pests such as mosquitoes and flies.

[0003] Since the pest control ingredients contained in such pest control products often have a strong unpleasant odor and are uniquely irritating to the nasal mucosa, etc., the use of pest control products for pest control treatment may sometimes cause significant discomfort to people in the treatment space, including the user.

[0004] In order to suppress the unpleasant odor and irritation, aerosol-type insecticides (pest control products) containing pyrethroids and mint-based flavorings have been proposed (for example, see Patent Document 1).

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2013-184895 Summary of the Invention

[0008] Problems to be solved by the invention

[0009] The pest control product of Patent Document 1 claims that the use of l-menthol and l-carvone as mint-based flavorings can reduce the unpleasant odor caused by the pest control ingredients, impart a clean (cool) feeling, and reduce the irritation of the pest control ingredients. However, because l-menthol and l-carvone are highly irritating to the nasal mucosa, etc., it is difficult to describe the pest control product as a whole as having low irritation. Therefore, it is difficult to describe the pest control product of Patent Document 1 as excellent in reducing the unpleasant odor caused by the pest control ingredients, providing a clean feeling, and achieving low irritation. Furthermore, if any of these properties are poor, users may tend to reduce the amount of the pest control product used or avoid using it, resulting in the possibility of inadequate pest control.

[0010] In view of the above circumstances, an object of the present invention is to provide a pest control product which not only reduces the unpleasant odor derived from the pest control ingredient and has an excellent minty-like cooling sensation, but also has low irritation derived from the fragrance ingredient.

[0011] Means of solving problems

[0012] The pest control product of the present invention, which solves the above-mentioned problems, is a pest control product for killing and / or repelling pests, comprising a pest control ingredient and a fragrance ingredient, wherein the fragrance ingredient contains menthone and does not contain l-menthol.

[0013] According to this configuration, the pest control product includes menthone as a fragrance ingredient, which can mask the unpleasant odor of the pest control ingredient. This results in a pest control product that is excellent in reducing the unpleasant odor. Furthermore, because menthone has a minty aroma, it provides an excellent cooling sensation. Furthermore, menthone is less irritating to the nasal mucosa, and since it does not contain l-menthol, it results in a pest control product with even lower irritation from the fragrance ingredient. Therefore, this pest control product not only reduces the unpleasant odor of the pest control ingredient and provides an excellent minty cooling sensation, but also exhibits low irritation from the fragrance ingredient.

[0014] In the pest control product of the present invention, the menthone is preferably isomenthone and / or l-menthone.

[0015] According to the pest control product of this configuration, since the menthone is isomenthone and / or l-menthone, it becomes a more excellent pest control product in terms of reduction of unpleasant odor derived from the pest control ingredients, a minty refreshing feeling, and low irritation derived from the fragrance ingredients.

[0016] In the pest control product of the present invention, the pest control ingredient is preferably a pyrethroid compound.

[0017] Pyrethroid compounds are pest control ingredients with an unpleasant odor. However, by combining these pyrethroid compounds with a fragrance component containing menthone, the unpleasant odor unique to these pyrethroid compounds is reduced. Furthermore, the unpleasant odor of the pyrethroid compounds is counteracted, providing a minty, refreshing sensation without the irritation of the fragrance component. Therefore, with this configuration, when the pest control component is a pyrethroid compound, the effectiveness of the pest control product is more readily felt.

[0018] In the pest control product of the present invention, the pyrethroid compound is preferably at least one selected from the group consisting of phenothrin, transfluthrin, permethrin, imiprothrin, cyphenothrin, etofenprox, and metofluthrin.

[0019] The pest control product of this configuration reduces the unpleasant odor of pyrethroid compounds, particularly phenothrin, transfluthrin, permethrin, imidathrin, cypermethrin, etofenprox, and metofluthrin, which have particularly unpleasant odors. Furthermore, it counteracts the unpleasant odor of these compounds and provides a minty, refreshing sensation without causing irritation from fragrance ingredients. Therefore, by selecting these pyrethroid compounds, the effectiveness of the pest control product is more readily felt.

[0020] In the pest control product of the present invention, the fragrance component preferably contains 1,8-cineole and / or d-limonene.

[0021] 1,8-Cineole and d-limonene have a mint-like aroma that is different from menthone. Therefore, in a pest control product with this configuration, if the fragrance component is 1,8-cineole and / or d-limonene, the aroma derived from 1,8-cineole and d-limonene combined with the fragrance derived from menthone creates a superior pest control product in terms of reduced unpleasant odor from the pest control ingredients, a minty cooling sensation, and reduced irritation from the fragrance ingredients.

[0022] In the pest control product of the present invention, the mass ratio (a / c) of the pest control component (a) to the fragrance component (c) is preferably 0.6 to 1500.

[0023] According to the pest control product of this configuration, by setting the mass ratio (a / c) within the appropriate range, the unpleasant odor due to the pest control ingredient is further reduced, the minty cooling sensation is more excellent, and the irritation from the fragrance ingredient is reduced.

[0024] In the pest control product of the present invention, the mass ratio (a / b) of the pest control component (a) to the menthone (b) is preferably 1.0 to 1500.

[0025] According to the pest control product of this configuration, by setting the mass ratio (a / b) within the appropriate range, the unpleasant odor due to the pest control ingredient is further reduced, the minty cooling sensation is more excellent, and the irritation from the fragrance ingredient is reduced.

[0026] In the pest control product of the present invention, the pest control product is preferably 3 The following space can reduce irritation and unpleasant odor products.

[0027] According to the present invention, the pest control product can be used in a space with a volume of 33.3m 3By reducing irritation and unpleasant odors in gaps, narrow spaces, and indoor spaces, the pest control product can be more effectively exerted.

[0028] The pest control product of the present invention is preferably formulated as an aerosol or a spray.

[0029] The pest control product of this configuration, when formulated as an aerosol or spray, can reduce the unpleasant odor of the pest control ingredients, provide a minty, refreshing sensation, and reduce the irritation of the fragrance ingredients. This allows the pest control ingredients to reach a wider range, thereby further enhancing the effectiveness of the pest control product.

[0030] In the pest control product of the present invention, the aerosol is preferably a metered-dose spray aerosol.

[0031] The pest control product of this configuration uses a metered-dose aerosol, allowing for the spraying of appropriate amounts of the pest control ingredient and fragrance component, depending on the number of sprays. This eliminates the need to spray unnecessarily large amounts of the pest control ingredient and fragrance component, effectively reducing the unpleasant odor of the pest control ingredient, providing a minty, refreshing sensation, and reducing the irritation of the fragrance component. DETAILED DESCRIPTION

[0032] Hereinafter, the pest control product of the present invention will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

[0033] [Pest control products]

[0034] The pest control product of the present invention contains a pest control ingredient and a fragrance ingredient, wherein the fragrance ingredient includes menthone and does not contain l-menthol. However, "does not contain l-menthol" does not necessarily mean that the l-menthol content is strictly 0% in all cases. For example, cases where a very small amount of l-menthol is unintentionally present, or where even a very small amount of l-menthol is intentionally present but does not function as l-menthol, are considered to contain no l-menthol. Examples of cases where a very small amount of l-menthol is unintentionally present include cases where other products containing l-menthol have been previously manufactured in pest control product manufacturing equipment, where a very small amount of l-menthol adheres to containers or piping and enters the pest control product as a contaminant, or cases where l-menthol floating or evaporating in the air of the manufacturing room is absorbed into the pest control product being manufactured and mixed in. In such cases, even if a very small amount of l-menthol is present, the pest control product is considered to contain no l-menthol. The dosage form of the pest control product is not particularly limited, as long as it contains a pest control ingredient and a flavoring ingredient containing menthone and not containing l-menthol. Such pest control products can be used, for example, as a liquid pest control composition obtained by dissolving or dispersing the pest control ingredient and the flavoring ingredient in a solvent (organic solvent or water); an aerosol obtained by preparing an aerosol stock solution of the pest control composition and filling a pressurized container with the aerosol stock solution and a propellant; or a spray obtained by storing the pest control composition in a container.

[0035] <Pest Control Ingredients>

[0036] Pest control ingredients that are one of the main components of the pest control product of this embodiment include: pyrethroid compounds, silicon compounds such as flutoxin, organophosphorus compounds such as dichlorvos and fenitrothion, carbamate compounds such as propoxur, neonicotinoid compounds such as dinotefuran, edamidin, and clothianidin, metamidine insecticides such as broflanilide, phenylpyrazole insecticides such as fipronil, oxadiazole insecticides such as metoxadiazone, indoxacarb, etc.

[0037] The present invention is effective when using pyrethroid compounds, particularly pyrethroid compounds, among these pest control ingredients. Pyrethroid compounds are pest control ingredients with an unpleasant odor. However, by combining these pyrethroid compounds with a fragrance component containing menthone, the unpleasant odor unique to pyrethroid compounds is reduced, counteracting the unpleasant odor of the pyrethroid compounds and providing a minty, refreshing sensation without the irritation of the fragrance component. Therefore, when the pest control ingredient is a pyrethroid compound, the effectiveness of the pest control product is more readily felt.

[0038] Examples of the pyrethroid compounds include transfluthrin, metofluthrin, profluthrin, cypermethrin, furamethrin, momfluorothrin, dimefluthrin, mepafluthrin, heptafluthrin, phenothrin, cypermethrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, fenpropathrin, tralomethrin, etofenprox, imiprothrin, allethrin, phthalthrin, prallethrin, resmethrin, and natural pyrethroids. The pyrethroid compound can be classified as having a vapor pressure of 1.0×10 -4 mmHg or more and less than 1.5×10 -3 mmHg of room temperature volatile pyrethroid compounds, and vapor pressure less than 1×10 -4mmHg. Examples of room-temperature volatile pyrethroid compounds include transfluthrin, metofluthrin, and profluthrin. Examples of low-volatility pyrethroid compounds include phenothrin, permethrin, imidacloprid, cypermethrin, and etofenprox. Among these, pyrethroid compounds are preferably phenothrin, transfluthrin, permethrin, imidacloprid, cypermethrin, and etofenprox. When these pyrethroid compounds are used, the unpleasant odor of phenothrin, transfluthrin, permethrin, imidathrin, cypermethrin, etofenprox, and metofluthrin, which are particularly unpleasant pyrethroid compounds, is reduced. Furthermore, the unpleasant odor of these compounds is counteracted, providing a minty, refreshing sensation without the irritation of fragrance ingredients. Therefore, by selecting these pyrethroid compounds, the effects of the pest control product can be more readily felt. These pest control ingredients can be used alone or as a mixture of two or more. Furthermore, when the pest control ingredient has optical isomers or geometric isomers based on asymmetric carbon atoms, each of these and any mixture thereof are also encompassed by the pest control ingredient of the present invention.

[0039] The content of the pest control ingredient in a pest control product (e.g., a pest control composition) is preferably 0.05 to 75.0 w / v%, more preferably 15.0 to 45.0 w / v%. By setting the content of the pest control ingredient to 0.05 w / v% or greater, the pest control effect of the pest control product can be enhanced. By setting the content of the pest control ingredient to 75.0 w / v% or less, the concentration of the pest control ingredient can be prevented from becoming excessively high, making it easier to appropriately prepare the pest control product.

[0040] <Fragrance ingredients>

[0041] The fragrance component, which is one of the main components of the pest control product of this embodiment, contains menthone. Menthone is a saturated cyclic terpene ketone and has a chemical formula of C 10 H 18O. Menthone is a compound with a mint-like aroma. Menthone has two asymmetric carbon atoms within its molecule, resulting in four optical isomers: d-menthone, l-menthone, d-isomenthone, and l-isomenthone. By including menthone in the fragrance component, it can mask the unpleasant odor of the pest control ingredient, resulting in a pest control product that is excellent in reducing this unpleasant odor. Furthermore, because menthone has a mint-like aroma, it provides a pest control product with an excellent cooling sensation. Furthermore, because menthone is less irritating to the nasal mucosa, etc., it is also an excellent pest control product in terms of low irritation.

[0042] When using a pest control product, users who experience an unpleasant odor, discomfort, or irritation may tend to reduce the amount of the product used or avoid using it altogether, potentially failing to adequately control pests. However, as described above, pest control products containing menthone-containing fragrance ingredients are superior in terms of reduced unpleasant odor from the pest control ingredient, a minty cooling sensation, and low irritation from the fragrance ingredient. Therefore, users can use the pest control product with peace of mind, resulting in excellent pest control effectiveness.

[0043] Among the optical isomers described above, menthone is preferably l-menthone or isomenthone (d-isomenthone and / or l-isomenthone). L-menthone and isomenthone are more superior in terms of reducing the unpleasant odor of the pest control ingredient, providing a minty cooling sensation, and reducing the irritation from the fragrance component. Menthone may be used alone or as a mixture of two or more optical isomers.

[0044] The fragrance component may also contain compounds other than menthone. As the compound other than menthone, a compound having a mint-like aroma is preferred, for example, 1,8-cineole, d-limonene, pinene, etc. Among them, 1,8-cineole and d-limonene are preferred. 1,8-cineole and d-limonene have a mint-like aroma different from that of menthone. Therefore, if the fragrance component is 1,8-cineole and d-limonene, the aroma from 1,8-cineole and d-limonene and the aroma from menthone are combined, resulting in a more excellent pest control product in terms of the effect of reducing the unpleasant odor caused by the pest control component, a mint-like cooling feeling, and low irritation from the fragrance component. Compounds other than menthone may be used alone or as a mixture of two or more.

[0045] On the other hand, the fragrance component does not contain l-menthol. Since the fragrance component does not contain l-menthol, which is highly irritating, the pest control product has less irritation from the fragrance component.

[0046] The (total) content of menthone in a pest control product (e.g., a pest control composition) is preferably 0.005 to 10.0 w / v%, more preferably 0.02 to 5.0 w / v%, even more preferably 0.075 to 3.0 w / v, and particularly preferably 0.1 to 0.5 w / v. By setting the menthone content to 0.005 w / v% or greater, the unpleasant odor from the pest control ingredients is further reduced, the minty cooling sensation is enhanced, and the irritation from the fragrance ingredients is reduced. Setting the menthone content to 10.0 w / v% or less prevents the fragrance from becoming excessive, thereby avoiding the possibility of causing discomfort to consumers who dislike strong fragrances and achieving economic benefits.

[0047] The (total) content of fragrance ingredients in a pest control product (e.g., a pest control composition) is preferably 0.01 to 10.0 w / v%, more preferably 0.02 to 5.0 w / v%, even more preferably 0.03 to 5.0 w / v, and particularly preferably 0.05 to 3.0 w / v. By setting the fragrance ingredient content to 0.01 w / v% or greater, the unpleasant odor from the pest control ingredients is further reduced, the minty cooling sensation is enhanced, and the irritation from the fragrance ingredients is reduced. Setting the fragrance ingredient content to 10.0 w / v% or less prevents excessive fragrance from the fragrance ingredients, thereby avoiding the possibility of causing discomfort to consumers who dislike strong fragrances and achieving economic benefits.

[0048] <Relationship between pest control ingredients and fragrance ingredients>

[0049] The mass ratio (a / b) of the pest control ingredient (a) to the menthone (b) contained in the fragrance ingredient (c) is preferably 0.015 to 10,000, more preferably 0.1 to 7,500, and even more preferably 1.0 to 1,500. By setting the mass ratio (a / b) within the above-described appropriate range, the unpleasant odor attributable to the pest control ingredient is further reduced, the minty cooling sensation is more excellent, and the irritation from the fragrance ingredient is reduced. Furthermore, the mass ratio (a / c) of the pest control ingredient (a) to the fragrance ingredient (c) is preferably 0.007 to 10,000, more preferably 0.05 to 7,500, and even more preferably 0.6 to 1,500. By setting the mass ratio (a / c) within the above-described appropriate range, the unpleasant odor attributable to the pest control ingredient is further reduced, the minty cooling sensation is more excellent, and the irritation from the fragrance ingredient is reduced.

[0050] <Solvent>

[0051] Pest control products are usually prepared in a state where the active ingredient is dissolved or dispersed in an organic solvent or water as a solvent. Examples of organic solvents include lower alcohols with 2 to 3 carbon atoms, such as ethanol and isopropyl alcohol (IPA); hydrocarbon solvents such as n-alkanes and isoalkanes; higher fatty acid esters with 16 to 20 carbon atoms, such as isopropyl myristate (IPM) and hexyl laurate; glycol solvents with 2 to 10 carbon atoms, such as ethylene glycol, propylene glycol, 1,3-butanediol, hexylene glycol, diethylene glycol, dipropylene glycol, and glycerol; glycol ether solvents with 3 to 10 carbon atoms, such as diethylene glycol monobutyl ether; and ketone solvents such as acetone and methyl isobutyl ketone. Among these, from the perspective of a sticky feel after treatment, it is preferred to contain a lower alcohol with 2 to 3 carbon atoms, and ethanol is more preferred. The solvents may be used alone or as a mixture of two or more.

[0052] The solvent content in a pest control product (e.g., a pest control composition) can be appropriately adjusted to account for the remainder of the total ingredients of the pest control product. Specifically, for example, the solvent content can be preferably set to 5.0 to 99.9 w / v%, more preferably 10.0 to 99.5 w / v%, and even more preferably 40.0 to 90.0 w / v%.

[0053] <Other ingredients>

[0054] Pest control products may contain, as necessary, ingredients other than pest control ingredients, fragrance ingredients, and any solvents, such as water, pH adjusters, nonionic surfactants, anionic surfactants, cationic surfactants, synergists for pyrethroid compounds, antifungals, antimicrobials, fungicides, and fragrances. In addition, they may contain antioxidants such as butylated hydroxytoluene, stabilizers such as monoethanolamine, triethanolamine, citric acid, citrates, sodium EDTA, and ascorbic acid, inorganic powders such as talc and silicic acid, deodorants, pigments, texture-imparting agents, UV absorption inhibitors, antistatic agents, defoaming agents, and excipients.

[0055] <Forms of Pest Control Products>

[0056] Pest control products can be used directly in liquid form as a pest control composition containing a pest control ingredient, a fragrance ingredient, and an optional solvent. Alternatively, they can be used in the form of an aerosol or spray. Aerosols or sprays can reduce the unpleasant odor of the pest control ingredient, provide a minty, refreshing sensation, and reduce the irritation of the fragrance ingredient. This allows the pest control ingredient to reach a wider range of users, resulting in a more pronounced effect.

[0057] (aerosol)

[0058] Pest control products can be made into aerosols by enclosing a pest control composition and a propellant used as needed in a pressure-resistant container. Examples of propellants include liquefied petroleum gas (LPG), dimethyl ether (DME), hydrofluoroolefins, nitrogen, carbon dioxide, nitrous oxide, compressed air, and the like. As an aerosol, a quantitative injection aerosol is preferably used, in which a pest control composition and a propellant used as needed are enclosed in a pressure-resistant container and a quantitative injection valve is installed. By making the aerosol a quantitative injection aerosol, an appropriate amount of pest control ingredients and fragrance ingredients can be injected according to the number of injections. Therefore, there is no need to inject an unnecessary large amount of pest control ingredients and fragrance ingredients, thereby effectively reducing unpleasant odors, providing a minty-like cool feeling, and reducing the irritation from the fragrance ingredients. In addition, the propellant is preferably used with the gauge pressure (20°C) adjusted to 0.10 to 0.70 MPa.

[0059] Regarding the aerosol, the volume ratio (d / e) of the pest control composition (d) to the propellant (e) in the pressure-resistant container is preferably 1 / 99 to 90 / 10, more preferably 10 / 90 to 80 / 20, and even more preferably 20 / 80 to 70 / 30.

[0060] When the aerosol is a metered-dose aerosol, the volume of each injection is not particularly limited, but is preferably set to 0.08 to 3.0 mL, more preferably 0.1 to 2.0 mL, and even more preferably 0.2 to 1.0 mL.

[0061] (Spray)

[0062] Pest control compositions can be used directly in liquid form. In this case, they can be placed directly in a container with a manual trigger pump to create a pump spray. The spray volume per injection is not particularly limited, but is preferably 0.07 to 3.0 mL, more preferably 0.1 to 2.0 mL, and even more preferably 0.2 to 1.0 mL.

[0063] <Applicable space>

[0064] The space to which the pest control product of this embodiment is applied is not particularly limited as long as it is an indoor space, and examples thereof include: 3 Gap space, 2.0~18.8m 3 The volume of a room with a width of 4.5 to 8 tatami mats is 18.8 to 33.3 m. 3 About (area 7.5~13.3m 2 , an indoor space with a height of 2.2 to 3.0 m, and a volume of 33.3 to 66.6 m equivalent to a room with 8 to 16 tatami mats 3 About (area 13.3~26.6m 2 , a wide indoor space with a height of 2.2 to 3.0 m). As can be seen, the pest control product of this embodiment has a space volume of 33.3 m 3 The following interstitial spaces, narrow spaces, and indoor spaces are particularly effective. Examples of interstitial spaces include wardrobes, closets, chests of drawers, kitchen cabinets, furniture, and spaces between furniture. Examples of narrow spaces include toilets, bathrooms, storage rooms, and vehicle interiors. Examples of indoor spaces include living rooms, dining rooms, and warehouses.

[0065] <Pests to be controlled>

[0066] Examples of pests that can be controlled by the pest control product of this embodiment include: cockroaches such as the black-brown cockroach, the German cockroach, the Yamato cockroach, the American cockroach, and the brown cockroach; crawling pests such as spiders, centipedes, ants, centipedes, millipedes, ball louse, rough porcelain louse, termites, caterpillars, mites, lice, ticks, and bed bugs; and flying pests such as mosquitoes, flies, moths, bees, stink bugs, bonito bugs, carcass-eating insects, bark beetles, clothes moths, and bag moths.

[0067] Example

[0068] Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to the Examples.

[0069] [Examples 1 to 26, Comparative Examples 1 to 15]

[0070] Pest control ingredients, fragrance ingredients, and solvents were mixed according to the formulations shown in Tables 1 to 5 to produce pest control compositions as pest control products. Furthermore, the pest control compositions and liquefied petroleum gas (LPG) as a propellant were pressurized and filled into pressure-resistant containers with metered-dispense valves of various spray capacities according to Tables 1 to 5. The spray nozzle was then positioned so that the spray axis formed an elevation angle (D) of 45 degrees relative to the horizontal plane when the pressure-resistant container was placed on a horizontal surface. An actuator with a nozzle diameter of 0.7 mm was then installed to produce test samples (aerosols) for Examples 1 to 26 and Comparative Examples 1 to 15. The resulting test samples for Examples 1 to 26 and Comparative Examples 1 to 15 were evaluated for irritation from the fragrance ingredients, a minty cooling sensation, and unpleasant odor from the pest control ingredients.

[0071] [Examples 27 to 37, Comparative Examples 16 to 20]

[0072] Pest control ingredients, fragrance ingredients, and solvents were mixed according to the formulations shown in Tables 6-8 to produce pest control compositions as pest control products. Furthermore, the pest control compositions and liquefied petroleum gas (LPG) as a propellant were pressurized and filled into pressure-resistant containers with metered-dispense valves of various spray capacities according to Tables 6-8. The spray nozzle was then positioned so that the spray axis formed an elevation angle (D) of 45 degrees relative to the horizontal plane when the pressure container was placed on a horizontal surface. An actuator with a nozzle diameter of 0.7 mm was then installed to produce test samples (aerosols) of Examples 27-37 and Comparative Examples 16-20. The resulting test samples of Examples 27-37 and Comparative Examples 16-20 were evaluated for irritation from the fragrance ingredients, a minty cooling sensation, and unpleasant odor from the pest control ingredients.

[0073] [Example 38, Comparative Examples 21-22]

[0074] According to the formulations shown in Tables 7 to 8, the pest control ingredients, the fragrance ingredients, and the solvent were mixed to obtain a pest control composition (liquid) as a pest control product. In addition, according to Tables 7 to 8, the pest control composition was filled into a spray container. The spray port was then set so that the spray axis was slightly tilted upward relative to the horizontal plane when the spray container was placed on a horizontal plane, and a spray member (Compact trigger Z-305, manufactured by MITANI VALVE Co., Ltd.) with a spray capacity of 0.3 mL per spray was loaded to obtain the test samples (sprays) of Example 38 and Comparative Examples 21 to 22. The obtained test samples of Example 38 and Comparative Examples 21 to 22 were evaluated for irritation from the fragrance ingredients, a minty cooling sensation, and an unpleasant odor caused by the pest control ingredients.

[0075] [Evaluation of irritation from fragrance ingredients]

[0076] Five pre-trained professional evaluators each entered a 2m 3 The test sample was sprayed three times continuously in a space with a nasal cavity, and sensory evaluation was conducted for irritation to the nasal mucosa. The sensory evaluation was based on a five-point scale of 1 to 5, based on the evaluation criteria shown below. Lower scores indicate less irritation from the fragrance ingredient. The average of the five evaluation scores was calculated, and evaluation was performed according to the following criteria. The results are shown in Tables 1 to 8.

[0077] (Score-based evaluation criteria)

[0078] 1 point: No irritation from fragrance ingredients

[0079] 2 points: Almost no irritation from fragrance ingredients

[0080] 3 points: Slight irritation from the fragrance ingredients

[0081] 4 points: There is a slight irritation from the fragrance ingredients

[0082] 5 points: There is a lot of irritation from the fragrance ingredients

[0083] (Average value criteria)

[0084] A: 1 point or more and less than 3 points (excellent)

[0085] B: 3 points or more and 3.5 points or less (good)

[0086] C: More than 3.5 points and less than 5 points (poor)

[0087] [Comments on the minty cooling sensation]

[0088] A liquid obtained by mixing 0.1w / v% of peppermint oil in ethanol as a solvent and liquefied petroleum gas as a propellant were pressurized and filled into a 0.4mL pressure-resistant container with a metered injection valve, and then loaded with an actuator to obtain a reference sample (aerosol) for evaluating Examples 1 to 37 and Comparative Examples 1 to 20. In addition, in this reference sample, the volume ratio of the peppermint oil mixture to the propellant was set to 30 / 70, and the actuator used was the same as that of Examples 1 to 37 and Comparative Examples 1 to 20. In addition, a liquid obtained by mixing 0.1w / v% of peppermint oil in ethanol as a solvent was filled into a spray container, and then loaded with a spray component to obtain a reference sample (spray) for evaluating Example 38 and Comparative Examples 21 to 22. In addition, in this reference sample, as a spray component, a spray component with a spray capacity of 0.3mL per time was used in the same manner as in Example 38 and Comparative Examples 21 to 22. First, 5 specialized evaluators who had been trained in advance each entered a 2m 3 The reference sample was sprayed three times continuously in a space to identify the fragrance. Then, the various test samples were sprayed in the same way to identify the fragrance. The evaluators compared the fragrance identified for the test samples with the fragrance identified for the reference sample, and scored them into five stages from 1 to 5 points according to the evaluation criteria shown below to obtain the evaluation score. The higher the evaluation score, the stronger the mint-like cooling feeling. The average of the evaluation scores of the five people was calculated and evaluated according to the following judgment criteria. The results are shown in Tables 1 to 8.

[0099] [Evaluation of unpleasant odor caused by pest control ingredients]

[0100] Five pre-trained professional evaluators each entered a 2m 3 The test sample was sprayed three times continuously in a room with a 20-degree view. Sensory evaluation was conducted to assess the degree of unpleasant odor attributed to the pest control ingredient. The sensory evaluation was based on a five-point scale of 1 to 5, based on the following evaluation criteria. Lower scores indicate a lower degree of unpleasant odor attributed to the pest control ingredient. The average of the five evaluation scores was calculated, and evaluation was performed according to the following criteria. The results are shown in Tables 1 to 8.

[0101] (Score-based evaluation criteria)

[0102] 1 point: No unpleasant odor at all

[0103] 2 points: Almost no unpleasant odor

[0104] 3 points: Slightly unpleasant odor

[0105] 4 points: Slightly unpleasant odor

[0106] 5 points: There are many unpleasant odors

[0107] (Average value criteria)

[0108] A: 1 point or more and less than 3 points (excellent)

[0109] B: 3 points or more and 3.5 points or less (good)

[0110] C: More than 3.5 points and less than 5 points (poor)

[0119] As shown in Tables 1 to 3, the test samples (pest control products) of Examples 1 to 26, which contain a pest control ingredient and a fragrance ingredient containing menthone but not l-menthol, exhibited low irritation from the fragrance ingredient and excellent reduction in a minty, refreshing sensation and unpleasant odor attributed to the pest control ingredient. Furthermore, a comparison of Examples 21 and 22 with Examples 24 and 25 showed that the test samples of Examples 24 and 25 using l-menthone tended to exhibit superior reduction in a minty, refreshing sensation and unpleasant odor attributed to the pest control ingredient compared to the test samples of Examples 21 and 22 using isomenthone. Furthermore, a comparison of Examples 21 and 22 with Examples 24 and 25, and further with Examples 13 and 14, shows that, as described above, the test samples of Examples 24 and 25 using l-menthone were superior in reducing the mint-like cooling sensation and the unpleasant odor attributable to the pest control ingredient compared to the test samples of Examples 21 and 22 using isomenthone, but the test samples of Examples 13 and 14 using these together were superior in reducing the mint-like cooling sensation and the unpleasant odor attributable to the pest control ingredient to the same extent as Examples 24 and 25 using l-menthone.

[0120] Comparisons of the test samples of Examples 1-12 and 16-20, which used isomenthone and / or l-menthone in combination with other flavoring ingredients (1,8-cineole and d-limonene), with the test samples of Examples 21-26, which used isomenthone or l-menthone alone, showed that even when other flavoring ingredients were used in combination with isomenthone or l-menthone, the irritation from the flavoring ingredients was low, and the minty cooling sensation and unpleasant odor attributed to the pest control ingredient were excellently reduced. Furthermore, all the test samples of Examples 1-3, which used isomenthone, l-menthone, 1,8-cineole, and d-limonene, demonstrated low irritation from the flavoring ingredients, and excellent reduction in the minty cooling sensation and unpleasant odor attributed to the pest control ingredient, comparable to the test samples of Examples 13 and 14, which used isomenthone and l-menthone in combination.

[0121] In contrast, as shown in Tables 4 and 5, the test samples of Comparative Examples 1 to 15, which did not use either isomenthone or l-menthone, exhibited at least one of the following: low irritation from the fragrance component, a minty cooling sensation, and a reduction in the unpleasant odor attributed to the pest control component, which were inferior to the test samples of Examples 1 to 26. Furthermore, the test samples of Comparative Examples 10 to 12, which used l-menthol, showed a strong irritation from l-menthol.

[0122] As shown in Tables 5-7, the test samples of Examples 27-37 differed from the types and values ​​set forth in Examples 1-26 in terms of the type of pest control ingredient, the mass ratio (a / b) of the pest control ingredient (a) to menthone (b), the mass ratio (a / c) of the pest control ingredient (a) to the fragrance ingredient (c), the volume ratio (d / e) of the pest control composition (d) to the propellant (e), and the volume per spray. In Example 38, the pest control composition was directly contained in a container equipped with a trigger pump to create a pump spray. Even in these examples, the test samples of Examples 1-38, by containing the pest control ingredient and a fragrance ingredient containing menthone but not l-menthol, exhibited low irritation from the fragrance ingredient, a minty cooling sensation, and excellent reduction in the unpleasant odor attributed to the pest control ingredient.

[0123] In contrast, as shown in Table 8, the test samples of Comparative Examples 16 to 22, which did not contain either isomenthone or l-menthone, exhibited at least one of the following: low irritation from the fragrance component, a minty cooling sensation, and a reduction in the unpleasant odor attributed to the pest control component. Furthermore, the results for the test samples of Comparative Examples 18 to 20 indicated that the inclusion of l-menthol resulted in increased irritation.

[0124] Furthermore, even when the type of pest control ingredient, the type of flavoring ingredient other than menthone, the mass ratio (a / b) of the pest control ingredient (a) to menthone (b), the mass ratio (a / c) of the pest control ingredient (a) to the flavoring ingredient (c), the volume ratio (d / e) of the pest control composition (d) to the propellant (e), and the volume per spray were set to types and values ​​other than those set in Examples 1 to 38, and even when either an aerosol or a spray was prepared, similarly to Examples 1 to 38, the irritation from the flavoring ingredient was reduced, a minty cooling sensation was achieved, and the unpleasant odor attributable to the pest control ingredient was excellently reduced, as compared to the comparative examples (Comparative Examples 1 to 9, 13 to 17, and 21 containing neither menthone nor l-menthol, and Comparative Examples 10 to 12, 18 to 20, and 22 containing neither menthone nor l-menthol).

[0125] Industrial applicability

[0126] The pest control product of the present invention can reduce the unpleasant odor caused by the pest control ingredient, provide a minty cooling sensation, and reduce the irritation caused by the fragrance ingredient, and therefore can be used for a wide range of pest control purposes.
