Description

[Technical field]

[0001] The present invention relates to a blood-sucking pest repellent composition containing a pest repellent component and a fragrance component, and a blood-sucking pest repellent method using said composition. [Background technology]

[0002] Conventionally, various blood-sucking pest control products have been developed for the purpose of protecting warm-blooded animals (humans, livestock, pets, etc.) from the blood-sucking behavior of blood-sucking pests such as blood-sucking mosquitoes, horseflies, blackflies, etc. For example, blood-sucking pest control products that contain pyrethroid-based repellent components that are volatile at room temperature as active ingredients are known (see, for example, Patent Document 1).

[0003] The blood-sucking pest control product of Patent Document 1 is described as having an excellent repellent effect against blood-sucking mosquitoes and the like, by applying a pyrethroid-based repellent component having a tetrafluorobenzyl skeleton to the skin or a skin covering material. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-188503 A Summary of the Invention [Problem to be solved by the invention]

[0005] Clothing may become tainted with bad odors such as sweat odor, middle-aged oily odor, and aging odor from the wearer while being worn. These bad odors cause discomfort to those around them and can sometimes cause problems such as smell harassment. In addition, blood-sucking pests such as mosquitoes tend to be attracted to bad odors such as sweat odor that adhere to the skin or clothing. Therefore, it is desirable to be able to continuously deodorize bad odors that adhere to the skin or clothing while going out, as this will reduce the chance of contact with blood-sucking pests and further reduce discomfort to those around.

[0006] The blood-sucking pest control product described in Patent Document 1 uses as its active ingredient a component that exhibits a high pest repellent effect, and is applied to the skin or a skin covering material to exhibit an excellent blood-sucking pest repellent effect. However, the deodorizing effect on the skin or clothing when repelling blood-sucking pests has not been fully studied, and there is still room for further study.

[0007] The present invention has been made in consideration of the above problems, and aims to provide a blood-sucking pest repellent composition that can repel blood-sucking pests and can continuously eliminate odors that adhere to the skin or clothing. It is also an object of the present invention to provide a blood-sucking pest repellent method that can simultaneously impart a pest repellent effect and a sustained deodorizing effect to the skin or clothing with a single treatment. [Means for solving the problem]

[0008] The blood-sucking pest repellent composition according to the present invention for solving the above problems is characterized by the following: A blood-sucking pest repellent composition containing a pest repellent component and a fragrance component, The pest repellent component is at least one selected from the group consisting of ethyl 3-(N-butylacetamido)propionate, icaridin, p-menthane-3,8-diol, and N,N-diethyltoluamide; The fragrance ingredient is a compound that does not have any electronic conjugated moiety other than an electronic conjugated moiety derived from a benzene ring, a benzoate structure, or a salicylate structure, has a carbon number of 6 to 18, a molecular weight of 98 to 270, and has carbon atoms, hydrogen atoms, and oxygen atoms, but does not have sulfur atoms, nitrogen atoms, or halogen atoms.

[0009] The present inventors have prepared various blood-sucking pest repellent compositions and conducted various tests, and have newly discovered that the blood-sucking pest repellent composition containing the specific pest repellent component and the fragrance component repels blood-sucking pests and can continuously deodorize the bad odors attached to the skin and clothing, and have completed the blood-sucking pest repellent composition of the present invention. According to the blood-sucking pest repellent composition of the present invention, the blood-sucking pest repellent composition containing the specific pest repellent component and the fragrance component repels blood-sucking pests, and can maintain the deodorizing function of the fragrance component for a long period of time due to the synergistic effect of the pest repellent component and the fragrance component. Therefore, by applying the blood-sucking pest repellent composition of the present invention to the skin or clothing before going out, in addition to repelling blood-sucking pests while going out, the deodorizing function of the fragrance component can be maintained while going out, and discomfort caused by the bad odor attached to the skin or clothing can be prevented.

[0010] In the blood-sucking pest repellent composition according to the present invention, The fragrance component is preferably at least one selected from the group consisting of cis-3-hexenol, dihydromyrcenol, ethyl linalool, linalool, geraniol, tetrahydrogeraniol, terpineol, phenylethyl alcohol, helional, lilial, benzyl benzoate, benzyl salicylate, cis-3-hexenyl salicylate, methyl dihydrojasmonate, linalyl acetate, raspberry ketone, galaxolide, ethylene brassylate, cyclopentadecanolide, menthone, limonene, citronellol, citronellal, 1,8-cineole, α-terpineol, borneol, camphor, patchouli alcohol, β-himachalene, benzyl acetate, benzyl alcohol, geranyl formate, eugenol, bisabolol oxide A, and α-pinene.

[0011] According to the blood-sucking pest repellent composition of the present configuration, by containing the above-mentioned fragrance component, the synergistic effect between the pest repellent component and the fragrance component is enhanced, and the durability of the deodorizing function can be improved.

[0012] In the blood-sucking pest repellent composition according to the present invention, The content of the flavor component is preferably 0.1 to 2.0 w / v %.

[0013] According to the blood-sucking pest repellent composition of the present invention, the content of the fragrance component is within an appropriate range, so that the odor adhering to the skin or clothing can be masked by the fragrance, thereby providing sufficient deodorizing properties.

[0014] In the blood-sucking pest repellent composition according to the present invention, The blending ratio (a / b) of the fragrance component (a) to the pest repellent component (b) is preferably 0.01 to 1.5 by weight.

[0015] According to the blood-sucking pest repellent composition of the present configuration, since the blending ratio is within an appropriate range, the pest repellent component can fully exert its repellent function against blood-sucking pests, while the synergistic effect of the pest repellent component and the fragrance component can be fully exerted, and the deodorizing function of the fragrance component can be maintained for a long period of time.

[0016] The blood-sucking pest repellent method according to the present invention for solving the above problems is characterized by the following features: A method for repelling blood-sucking pests using any one of the blood-sucking pest repellent compositions, comprising: A spraying step of spraying the blood-sucking pest repellent composition onto the skin or clothing to be treated; A step of changing the position where the blood-sucking pest repellent composition is sprayed on the skin or clothing; The purpose of this study is to encompass the above.

[0017] According to the blood-sucking pest repellent method of this configuration, the blood-sucking pest repellent composition is sprayed on the skin or clothing to be treated, and the position where the blood-sucking pest repellent composition is sprayed on the skin or clothing can be changed to impart a pest repellent effect and a deodorizing function to the entire skin or clothing. The blood-sucking pest repellent composition containing a specific pest repellent component and a fragrance component has a pest repellent function against blood-sucking pests due to the pest repellent component, and the deodorizing function of the fragrance component can be sustained for a long period of time due to the synergistic effect between the pest repellent component and the fragrance component. Therefore, by simply spraying the blood-sucking pest repellent composition of the present invention once on the skin or clothing according to the blood-sucking pest repellent method of the present invention before going out, in addition to repelling blood-sucking pests while going out, the deodorizing function of the fragrance component can be sustained while going out, and discomfort caused by the bad odor attached to the skin or clothing can be prevented. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The blood-sucking pest repellent composition and the blood-sucking pest repellent method of the present invention will be described below. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

[0019] <Blood-sucking insect repellent composition> The blood-sucking pest repellent composition of the present invention contains a fragrance component and a pest repellent component.

[0020] As the pest repellent component, which is one of the main components of the blood-sucking pest repellent composition of the present invention, ethyl 3-(N-butylacetamido)propionate (hereinafter referred to as "IR3535"), icaridin (also known as "1-methylpropyl 2-(2-hydroxyethyl)-1-piperidinecarboxylate"), p-menthane-3,8-diol (hereinafter referred to as "PMD"), and N,N-diethyltoluamide (hereinafter referred to as "DEET") are used. These can be used alone, but may also be used in the form of a mixture of two or more. IR3535, icaridin, PMD, and DEET are volatile and have a high repellent effect against blood-sucking pests (excluding lice), especially adult mosquitoes, black flies, horseflies, midges, ticks, cheyletid mites, flour mites, and cat fleas. They also have a repellent effect against unpleasant pests such as midges, moth flies, and ants. Thus, IR3535, icaridin, PMD, and DEET have been used as pest repellents in the past, but the present inventors have newly discovered that IR3535, icaridin, PMD, and DEET have a sustaining function that sustains the deodorizing function of a specific fragrance component described below in addition to the above-mentioned blood-sucking pest repellent effect. The blood-sucking pest repellent composition of the present invention is attached to the skin or clothing by spraying or the like, and the pest repellent component is evaporated from the skin or clothing in use to prevent the approach or contact of blood-sucking pests, and the deodorization of the bad odor attached to the skin or clothing can be sustained for a long period of time while preventing blood-sucking by blood-sucking pests. In the clothing being worn, the evaporation of the pest repellent component is promoted by the user's body temperature, so that the approach or contact of blood-sucking pests can be more effectively prevented. In addition, since it can deodorize the bad odor that attracts blood-sucking pests such as mosquitoes, it can exert a synergistic repellent effect. IR3535, Icaridin, PMD, and DEET are highly safe for the human body, so they can be sprayed directly onto the skin of the arms, legs, etc. In addition, IR3535, Icaridin, and PMD are unlikely to cause stains or discoloration on textile products, and are also almost odorless. Therefore, the blood-sucking pest repellent composition of the present invention can be used on clothing without worrying about damage to clothing or the odor of the pest repellent components.The content of the pest repellent component in the blood-sucking pest repellent composition is preferably 0.4 to 30.0 w / v %. Within this range, the blood-sucking pest repellent composition can be applied to the skin or clothing by spraying or the like to exert a repellent effect against blood-sucking pests while exerting a synergistic effect with a specific fragrance component described later, thereby improving the durability of the deodorizing function.

[0021] As the fragrance component, which is one of the main components of the blood-sucking pest repellent composition of the present invention, a compound is used that has no electronic conjugated portion other than the electronic conjugated portion derived from a benzene ring, a benzoate structure, or a salicylate structure, has a carbon number of 6 to 18, a molecular weight of 98 to 270, has carbon atoms, hydrogen atoms, and oxygen atoms, and has no sulfur atoms, nitrogen atoms, or halogen atoms. Such a compound has an excellent deodorizing function that masks bad odors (sweat odor, middle-aged oily odor, aging odor, etc.) attached to the skin or clothing with a fragrance, and can maintain its deodorizing function for a long time due to a synergistic effect with IR3535, icaridin, PMD, and DEET used as pest repellent components in the present invention.

[0056] [ka] Examples of such compounds include α-pinene represented by the following formula (hereinafter referred to as “compound i”).

[0057] The above compounds A to Z and a to i may be used alone or in combination. These fragrance components may be blended as essential oils such as mint oil, lavender oil, rose oil, geranium oil, eucalyptus oil, lemon oil, rosemary oil, bergamot oil, citronella oil, orange oil, lavandin oil, patchouli oil, cedarwood oil, jasmine oil, petitgrain oil, lemon eucalyptus oil, grapefruit oil, lime oil, pine oil, chamomile oil, clove oil, and turpentine oil. In the present invention, even if the fragrance components are blended as essential oils, when the essential oil contains 1.0 mass% or more of the fragrance components, they are defined as being blended as individual fragrance components. The content of the fragrance components is preferably 0.1 to 2.0 w / v%. If the content of the fragrance components is within such a range, it is possible to mask the bad odors attached to the skin or clothing and obtain sufficient deodorizing properties.

[0058] In the blood-sucking pest repellent composition of the present invention, when the perfume component contains menthone, limonene, terpineol, linalool, or linalyl acetate, it is preferable because a synergistic effect is observed in the blood-sucking pest repellent function. Among them, it is more preferable to contain linalool and linalyl acetate, and by containing linalool and linalyl acetate, the synergistic effect of the deodorizing function of the pest repellent component and the perfume component becomes larger, and the deodorizing function by the perfume component can be further improved in duration. In addition, it is preferable to adjust the blending weight ratio of linalool and linalyl acetate to 0.5 to 2.0.

[0059] In the blood-sucking pest repellent composition of the present invention, the blending ratio (a / b) of the fragrant component (a) to the pest repellent component (b) is preferably adjusted to 0.01 to 1.5 by weight. If the blending ratio (a / b) is within such a range, the synergistic effect between the pest repellent component and the fragrant component is large, and the deodorizing function of the fragrant component is sustained for a long period of time.

[0060] In addition to the above components, the blood-sucking pest repellent composition of the present invention may also be appropriately blended with a stabilizer for the pest repellent component, an antifungal agent for molds and fungi, an antibacterial agent, a bactericide, an antistatic agent, an antifoaming agent, a cooling agent, etc. For example, when IR3535 is used as the pest repellent component, triethanolamine can be blended. By containing triethanolamine, the stability of IR3535, which is easily decomposed under acidic conditions, can be improved, and the content of IR3535 can be prevented from excessively decreasing even when the blood-sucking pest repellent composition is stored for a long period of time. The content of triethanolamine in the blood-sucking pest repellent composition is preferably 0.05 to 0.2 w / v%. Within such a range, the stability of IR3535 can be sufficiently improved, so that the blood-sucking pest repellent composition is excellent in long-term storage and easy to use. When IR3535 is used as the pest repellent component, it is preferable to use menthol in addition to triethanolamine. The content of menthol in the blood-sucking pest repellent composition is preferably 0.1 to 1.5 w / v%. In such a range, the stability of IR3535 can be further improved by the synergistic effect of triethanolamine and menthol, and a refreshing feeling can also be imparted. On the other hand, when icaridin, PMD or DEET is used as the pest repellent component, menthol can be blended. The content of menthol in the blood-sucking pest repellent composition is preferably 0.1 to 1.5 w / v%. In such a range, the stability of icaridin, PMD or DEET can be further improved by the stability improving effect of menthol, and a refreshing feeling can also be imparted. Note that, although menthol has been used as a fragrance in the past, when the present inventors prepared various blood-sucking pest repellent compositions, when the content of menthol was within the above range, menthol did not exhibit a deodorizing function of deodorizing the bad odor attached to the skin or clothing. Furthermore, even when the menthol content was increased beyond the above range to such an extent that a deodorizing function was exhibited, the deodorizing function could not be sustained by IR3535, icaridin, PMD, and DEET. For this reason, menthol is not included as a fragrance component of the present invention.Antifungal agents, antibacterial agents, and bactericides include hinokitiol, 2-mercaptobenzothiazole, 2-(4-thiazolyl)benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, triforine, 3-methyl-4-isopropylphenol, ortho-phenylphenol, and the like.

[0061] The blood-sucking pest repellent composition of the present invention is prepared by mixing the above-mentioned components in an appropriate weight ratio, and adding ketone-based solvents such as acetone, methyl ethyl ketone, diethyl ketone, and cyclohexanone, alcohol-based solvents such as methanol, ethanol, butanol, 1-propanol, 2-propanol, and 1-butanol, glycol-based solvents such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, 1,3-butylene glycol, and dipropylene glycol, glycol ether-based solvents such as diethylene glycol monomethyl ether, diethylene glycol monobutyl ether, triethylene glycol monomethyl ether, and phenoxyethanol, hydrocarbon-based solvents such as toluene, xylene, normal hexane, n-paraffin, and isoparaffin, ester-based solvents such as ethyl acetate, butyl acetate, amyl acetate, and ethyl lactate, and water, etc., to adjust the concentration of each component to an appropriate level. Among them, it is preferable to add water and alcohols, or water and glycol ethers. As the alcohols, lower alcohols having 2 to 3 carbon atoms are preferable, and ethanol is particularly suitable. As the glycol ethers, glycol monoethers are preferred, and phenoxyethanol is particularly preferred.

[0062] <Product form> The product form of the blood-sucking pest repellent composition of the present invention may be a spray product, a gel product, a coating product, a powder product, a sheet product, etc. Each product form will be described below.

[0063] <Spray products for controlling blood-sucking pests> A preferred product form of the blood-sucking pest repellent composition of the present invention is a spray product. For example, the blood-sucking pest repellent composition of the present invention and, if necessary, a propellant are enclosed in a spray container to form a spray product for controlling blood-sucking pests. The spray container is preferably equipped with a push-down spray or a trigger sprayer. This allows the blood-sucking pest repellent composition to spread when sprayed, and the amount of the blood-sucking pest repellent composition attached to the skin or clothing of the treatment target is approximately uniform. In addition, a precise amount of the blood-sucking pest repellent composition can be applied to the skin or clothing of the treatment target depending on the number of sprays.

[0064] <Gel products for controlling blood-sucking pests> A preferred product form of the blood-sucking pest repellent composition of the present invention is a gel product. For example, a gel product for controlling blood-sucking pests is formed by sealing the blood-sucking pest repellent composition, a gel base, and a gelling agent in a gel container. Examples of the gel base include water-soluble polymers such as carboxyvinyl polymers, polyvinyl alcohol, and polyvinylpyrrolidone, acrylic acid-based polymer compounds such as acrylic acid copolymers, acrylic acid / alkyl methacrylate copolymers, and alkyl acrylate / diacetone acrylamide copolymers, and polysaccharides such as alginic acid and its salts, and carboxyvinyl polymers are particularly preferred. Examples of the gelling agent include amines such as triethanolamine and tetrahydroxypropylethylenediamine, sodium hydroxide, and aminomethylpropanol.

[0065] <Application products for controlling blood-sucking pests> A preferred product form of the blood-sucking pest repellent composition of the present invention is a coating product. For example, the blood-sucking pest repellent composition of the present invention is enclosed in a drop pump container to form a coating product for controlling blood-sucking pests. Examples of coating products include creams, liquids, emulsions, water-soluble products, microemulsions, etc.

[0066] <Powder product for controlling blood-sucking pests> A preferred product form of the blood-sucking pest repellent composition of the present invention is a powder product. For example, a powder product for controlling blood-sucking pests is formed by sealing the blood-sucking pest repellent composition, a moisture retaining agent, and an oil absorbent in a powder container. Examples of the moisture retaining agent include talc, kaolin, bentonite, etc., and talc is particularly preferred. Examples of the oil absorbent include silicic acid anhydride, calcium silicate, hydrophobic silica, diatomaceous earth, and other silicic acid compounds, and silicic acid anhydride, which has a high oil absorption effect, is particularly preferred.

[0067] <Sheet products for controlling blood-sucking pests> A preferred product form of the blood-sucking pest repellent composition of the present invention is a sheet product. For example, a sheet product for controlling blood-sucking pests is formed by impregnating a sheet substrate with the blood-sucking pest repellent composition of the present invention. Methods for impregnating a sheet substrate with the blood-sucking pest repellent composition include, for example, a method of spraying the blood-sucking pest repellent composition onto a sheet substrate using a spray, an air gun, or the like, a method of directly applying the blood-sucking pest repellent composition onto a sheet substrate using a slit-type nozzle, or a method of impregnating the sheet substrate with the blood-sucking pest repellent composition after placing the sheet substrate in a packaging container. As the sheet substrate, any of natural fibers, synthetic fibers, and nonwoven fabrics and woven fabrics made by blending these fibers can be used. Specific examples include nonwoven and woven fabrics made of cupra, rayon, acetate, acrylic, polyester, polyethylene, polypropylene, polyurethane, polyamide, cotton, and blends of these, as well as wet and dry pulp sheets and pulp sheets reinforced with thermoplastic resins (polyethylene, polypropylene, polyethylene terephthalate, etc.).

[0068] <How to deodorize clothing> By spraying the blood-sucking pest repellent composition of the present invention, particularly on clothing, a clothing deodorizing method can be carried out using the above-mentioned spray product for controlling blood-sucking pests. Specifically, the user presses down the spray head of the spray product for controlling blood-sucking pests to spray the blood-sucking pest repellent composition toward clothing such as clothing and hats, or holds the trigger of the spray product for controlling blood-sucking pests and sprays the blood-sucking pest repellent composition toward clothing such as clothing and hats. As a result, the blood-sucking pest repellent composition adheres to the surface of the clothing. In the blood-sucking pest repellent composition of the present invention, IR3535, icaridin, PMD, and DEET, which are highly safe for humans, are used as pest repellent components, so it is also possible to spray the clothing while wearing it. By carrying out a spray treatment of the blood-sucking pest repellent composition, an excellent repellent effect against blood-sucking pests and a sustained deodorizing function are imparted. As a result, it is possible to prevent the approach or contact of blood-sucking pests, prevent blood-sucking by blood-sucking pests, and deodorize the bad odor adhering to clothing. It is also possible to spray the product directly onto the skin of the arms and legs.

[0069] <How to repel blood-sucking pests> The blood-sucking pest repellent method of the present invention includes a spraying step of spraying a blood-sucking pest repellent composition containing a pest repellent component and a fragrance component on the skin or clothing to be treated, and a changing step of changing the position where the blood-sucking pest repellent composition is sprayed on the skin or clothing so that sufficient pest repellent and deodorizing effects are maintained on the skin or clothing. In the blood-sucking pest repellent and deodorizing method of the present invention, the user only needs to spray the blood-sucking pest control spray product while moving it appropriately so that the blood-sucking pest repellent composition adheres to the entire skin or clothing. For example, by carefully spraying the areas of the clothing where odors are particularly noticeable (e.g., underarms, around the neck, around the legs, etc.), an effective pest repellent effect and a sustained deodorizing effect can be simultaneously imparted to the clothing. In this way, by carrying out the blood-sucking pest repellent and deodorizing method of the present invention, a pest repellent effect and a sustained deodorizing effect can be simultaneously imparted to the skin or clothing with a single treatment. Furthermore, skin or clothing treated with the blood-sucking pest repellent method of the present invention has a synergistic effect between the pest repellent component and the fragrance component, described below, and the deodorizing function of the fragrance component lasts for a long period of time. Therefore, even if you are outside all day, blood-sucking pests will not come near you and you will be able to be active for a long time in comfort without having to worry about odors.

[0070] The blood-sucking pest repellent composition of the present invention can maintain the deodorizing function of the fragrance component for a long period of time by combining the pest repellent component with a specific fragrance component, due to the synergistic effect of the pest repellent component and the fragrance component. The duration of the deodorizing function varies depending on the combination of the pest repellent component and the fragrance component, the mixing ratio of both components, the use conditions of the blood-sucking pest repellent composition, etc., but it is sufficient to maintain the deodorizing function for about half a day to a day. Therefore, if the spray treatment is performed before going out according to the blood-sucking pest repellent method of the present invention implemented using this blood-sucking pest repellent composition, the deodorizing function of the fragrance component will continue for about 12 hours while going out, and discomfort caused by the bad odor attached to the skin or clothing can be prevented. EXAMPLES

[0120] [Table 1]

[0121] [Table 2]

[0122] [Deodorizing function confirmation test] Deodorizing function confirmation tests were conducted for sweat odor, middle-aged oily odor, and aged odor. For sweat odor, a test cotton cloth (5 cm x 5 cm cotton cloth (gold width No. 3)) was placed in a high-waisted petri dish (outer diameter 75 mm, height 60 mm), and an appropriate amount of an ethanol solution of isovaleric acid (manufactured by Nacalai Tesque, Inc.) was sprayed in a spray vial as a test odor. For middle-aged oily odor, a test cotton cloth was placed in a high-waisted petri dish, and an appropriate amount of an ethanol solution of diacetyl (manufactured by Nacalai Tesque, Inc.) was sprayed in a spray vial as a test odor. For aged odor, a test cotton cloth was placed in a high-waisted petri dish, and an appropriate amount of an ethanol solution of 2-nonenal (manufactured by Tokyo Kasei Kogyo Co., Ltd.) was sprayed in a spray vial as a test odor.

[0123] For sweat odor, 0.03 mL of the test solution of Examples 1 to 60 and Comparative Examples 1 to 61 was sprayed in a spray vial onto each test cotton fabric to which a malodor had been added, and the odor in the high-waisted petri dish was evaluated immediately after spraying the test solution, 3 hours later, and 12 hours later. For middle-aged oily odor and aged odor, 0.03 mL of the test solution of Examples 1 to 56 and Comparative Examples 1 to 57 was sprayed in a spray vial onto each test cotton fabric to which a malodor had been added, and the odor in the high-waisted petri dish was evaluated immediately after spraying the test solution, 3 hours later, and 12 hours later. The odor was evaluated by five testers using the following five-stage odor intensity rating method, and the average score was calculated. An average score of 0 or more and less than 2 was marked as ○, 2 or more and less than 3 was marked as △, and 3 or more and less than 4 was marked as ×.

[0124] In Example 1, in order to confirm the influence of isopropylmethylphenol (IPMP), menthol, and triethanolamine (TEA) on this test, the same test was carried out on a sample that did not contain any of these ingredients, and on a sample that contained one or two of these ingredients. As a result, it was confirmed that these ingredients did not affect the results of this test. 0: No scent 1: Faintly felt 2: Feeling weak 3: Clearly felt 4: I feel strongly

[0125] The results of the sweat odor deodorizing function confirmation test are shown in Tables 3 and 4.

[0126] [Table 3]

[0127] [Table 4]

[0128] The results of the deodorizing function confirmation test against middle-aged oily odor are shown in Tables 5 and 6.

[0129] [Table 5]

[0130] [Table 6]

[0131] The results of the deodorizing function confirmation test against aging odor are shown in Tables 7 and 8.

[0132] [Table 7]

[0133] [Table 8]

[0134] As a result of the deodorizing function confirmation test, the blood-sucking pest repellent composition having the characteristic configuration of the present invention, whether it is Examples 1 to 27 containing IR3535 as the pest repellent component or Examples 28 to 60 containing icaridin as the pest repellent component, showed excellent deodorizing properties against sweat odor, middle-aged oily odor, and aged odor even 12 hours after spraying the test solution. From this, it is considered that by spraying the blood-sucking pest repellent composition having the characteristic configuration of the present invention on the skin or clothing before going outside, the deodorizing function of the fragrance component will last for about 12 hours while going outside, and discomfort caused by bad odors attached to the skin or clothing can be prevented.

[0135] On the other hand, the blood-sucking pest repellent compositions of Comparative Examples 1 to 21 and 57 to 61, which do not contain a pest repellent component, contain the same fragrance components as Examples 1 to 27, which contain IR3535 as the pest repellent component, and Examples 28 to 60, which contain icaridin as the pest repellent component, but only showed deodorizing properties against sweat odor, middle-aged oily odor, and aging odor for up to 3 hours after spraying the test solution, and did not show sufficient deodorizing properties 12 hours after spraying the test solution.

[0136] The blood-sucking pest repellent composition of Comparative Example 22 contains IR3535 as a pest repellent component similar to Examples 1 to 27, and the blood-sucking pest repellent composition of Comparative Example 23 contains Icaridin as a pest repellent component similar to Examples 28 to 56, but neither Comparative Example 22 nor 23 contains a fragrance component. Such blood-sucking pest repellent compositions of Comparative Examples 22 and 23 did not exhibit deodorizing properties against sweat odor, middle-aged oily odor, and aged odor. From this, it was confirmed that the pest repellent components IR3535 and Icaridin alone do not have deodorizing properties. Although the pest repellent ingredients IR3535 and icaridin do not have deodorizing properties on their own, the deodorizing function lasted longer in the blood-sucking pest repellent compositions of Examples 1 to 56 in which a pest repellent ingredient was simply added to these ingredients compared to the blood-sucking pest repellent compositions of Comparative Examples 1 to 21. This is thought to be because the pest repellent ingredient exerts some kind of synergistic effect with the specific fragrance ingredient specified in the present invention.

[0137] In addition, in Comparative Examples 24 to 56, in which a compound having an electronic conjugated portion other than that derived from a benzene ring, a benzoate structure, or a salicylate structure was used as a fragrance component, the deodorizing effect was only observed for sweat odor, middle-aged greasy odor, and aged odor for up to 3 hours after the test solution was sprayed, and no sufficient deodorizing effect was observed 12 hours after the test solution was sprayed. Even in the case of containing IR3535 as the pest repellent component (Comparative Examples 24 to 34) and the case of containing icaridin as the pest repellent component (Comparative Examples 35 to 45), the deodorizing function did not last for a long time, probably because the specific fragrance component specified in the present invention was not used, and therefore no synergistic effect between the pest repellent component and the fragrance component was obtained.

[0138] From the above results, it was confirmed that the blood-sucking pest repellent compositions (Examples 1 to 60) having the characteristic configuration of the present invention combine specific pest repellent components with specific fragrance components, thereby obtaining a synergistic effect between the pest repellent components and the fragrance components, and that the deodorizing function of the fragrance components is sustained for a long period of time.

[0139] [Outdoor performance verification test 1] The blood-sucking pest repellent composition of the present invention was prepared as a pump spray product (Examples 61 to 64), and was actually sprayed onto clothing to confirm its outdoor performance.

[0140] <Example 61> 0.5g (0.5w / v%) of menthone, 5.0g (5.0w / v%) of icaridin, 40g (40w / v%) of purified water, and the balance of absolute ethanol were mixed to prepare a blood-sucking pest repellent composition with a total volume of 100mL. The blending ratio (a / b) of the fragrance component (a) and the pest repellent component (b) of this blood-sucking pest repellent composition was 0.10 by weight. The prepared blood-sucking pest repellent composition was filled into a push-down pump spray container to obtain a blood-sucking pest repellent spray product 1.

[0141] <Example 62> 2.0 g (2.0 w / v%) of limonene, 30.0 g (30.0 w / v%) of icaridin, 40 g (40 w / v%) of purified water, and the balance of absolute ethanol were mixed to prepare a blood-sucking pest repellent composition with a total volume of 100 mL. The blending ratio (a / b) of the fragrance component (a) and the pest repellent component (b) of this blood-sucking pest repellent composition was 0.07 by weight. The prepared blood-sucking pest repellent composition was filled into a push-down pump spray container to obtain a blood-sucking pest repellent spray product 2.

[0142] <Example 63> Linalool 0.9g (0.9w / v%), icaridin 15.0g (15.0w / v%), purified water 40g (40w / v%), and absolute ethanol (balance) were mixed to prepare a blood-sucking pest repellent composition with a total volume of 100mL. The blending ratio (a / b) of the fragrance component (a) and the pest repellent component (b) of this blood-sucking pest repellent composition was 0.06 by weight. The prepared blood-sucking pest repellent composition was filled into a push-down pump spray container to obtain a blood-sucking pest repellent spray product 3.

[0143] <Example 64> Lavender oil (containing 30% linalool, 40% linalyl acetate, and other components) was mixed at 0.9 g (0.9 w / v%), icaridin at 5.0 g (5.0 w / v%), purified water at 40 g (40 w / v%), and anhydrous ethanol was mixed as the balance to prepare a blood-sucking pest repellent composition with a total volume of 100 mL. The fragrance component (a) contained in 0.9 g of lavender oil was 0.27 g of linalool and 0.36 g of linalyl acetate, and the blending ratio (a / b) of the fragrance component (a) and the pest repellent component (b) of this blood-sucking pest repellent composition was 0.13 by weight. The prepared blood-sucking pest repellent composition was filled into a push-down pump spray container to obtain a blood-sucking pest repellent spray product 4.

[0144] Four panelists (one male in his 30s, one male in his 40s, one male in his 50s, and one male in his 60s) each chose one of the above blood-sucking pest repellent spray products 1 to 4 (Examples 61 to 64), sprayed it on their clothes, and walked freely in the park from 10:00 a.m. to 4:00 p.m. on a sunny day. None of the four panelists were bitten by blood-sucking pests such as mosquitoes during their walk, and they were able to spend their time comfortably without worrying about the smell from their clothes. In particular, the blood-sucking pest repellent spray product 4 of Example 64, which uses "linalool" and "linalyl acetate" as fragrance ingredients, had a very excellent repellent effect against blood-sucking pests and deodorizing effect compared to the blood-sucking pest repellent spray products 1 to 3 of Examples 61 to 63, which used other fragrance ingredients. The fact that the combination of "linalool" and "linalyl acetate" exhibits a specifically high effect is a new finding discovered by the present inventors through trial and error involving various combinations of fragrance components.

[0145] [Outdoor performance verification test 2] The blood-sucking pest repellent composition of the present invention was prepared as a pump spray product (Example 65), and was actually sprayed onto clothing to confirm its outdoor performance.

[0146] <Example 65> 0.9g (0.9w / v%) of peppermint oil (containing 60% menthol, 20% menthone, and other components), 5.0g (5.0w / v%) of icaridin, 40g (40w / v%) of purified water, and the balance of anhydrous ethanol were mixed to prepare a blood-sucking pest repellent composition with a total volume of 100mL. The fragrance component (a) contained in 0.9g of peppermint oil was 0.18g of menthone, and the blending ratio (a / b) of the fragrance component (a) and the pest repellent component (b) of this blood-sucking pest repellent composition was 0.036 by weight. The prepared blood-sucking pest repellent composition was filled into a push-down pump spray container to obtain a blood-sucking pest repellent spray product 5.

[0147] Two testers (one male in his 30s and one male in his 50s) sprayed the above-mentioned blood-sucking pest repellent spray product 5 on their own clothes and walked freely in a park from 10:00 am to 4:00 pm on a sunny day. Neither of the two testers were bitten by blood-sucking pests such as mosquitoes during their walk, and they were able to spend the day comfortably without having to worry about odors coming from their clothes.
