Summary of the Invention

Problems to be Solved by the Invention

[0005] Malodors such as sweat odor, middle-aged body odor, and aging odor derived from the wearer may adhere to clothing during wear. These malodors cause discomfort to the surroundings and may sometimes cause problems such as smell harassment. In addition, blood-sucking pests such as mosquitoes tend to be attracted to malodors such as sweat odor adhering to the skin or clothing. Therefore, it is desirable to be able to continuously deodorize the malodors adhering to the skin or clothing during going out, which leads to a reduction in the chance of contact with blood-sucking pests and further reduces discomfort to the surroundings.

[0006] The blood-sucking insect control product described in Patent Document 1 uses an active ingredient that exhibits a high insect-repellent effect, and therefore, when applied to the skin or skin coverings, it exhibits excellent blood-sucking insect repellent effects. However, the deodorizing effect on the skin and clothing during blood-sucking insect repellent application has not been sufficiently studied, and there is still room for further research.

[0007] This invention has been made in view of the above problems, and aims to provide a blood-sucking insect repellent composition that can repel blood-sucking insects and continuously deodorize unpleasant odors that adhere to the skin and clothing. Furthermore, it aims to provide a blood-sucking insect repellent method that can simultaneously impart an insect-repellent effect and a sustained deodorizing effect to the skin and clothing in a single treatment. [Means for solving the problem]

[0008] The characteristic configuration of the blood-sucking insect repellent composition according to the present invention, which solves the above problems, is as follows: A blood-sucking insect repellent composition containing an insect repellent component and a fragrance component, The insect repellent component is at least one selected from the group consisting of ethyl 3-(N-butylacetamide)propionate, picaridin, p-menthane-3,8-diol, and N,N-diethyltoluamide. The aforementioned fragrance component is a compound that does not have any electron-conjugated moieties other than those derived from a benzene ring, a benzoic acid ester structure, or a salicylic acid ester structure, has 6 to 18 carbon atoms, a molecular weight of 98 to 270, contains carbon atoms, hydrogen atoms, and oxygen atoms, but does not contain sulfur atoms, nitrogen atoms, or halogen atoms.

[0009] The present invention was developed by the inventors after they prepared various blood-sucking insect repellent compositions and conducted numerous tests. They discovered that a blood-sucking insect repellent composition containing the above-mentioned specific insect repellent component and fragrance component not only repels blood-sucking insects but also provides sustained deodorization of unpleasant odors that adhere to the skin and clothing. The present invention provides a blood-sucking insect repellent composition containing the above-mentioned specific insect repellent component and fragrance component. Furthermore, the synergistic effect of the insect repellent component and fragrance component allows the deodorizing function of the fragrance component to be sustained over a long period. Therefore, by applying the present invention's blood-sucking insect repellent composition to the skin and clothing before going out, in addition to repelling blood-sucking insects while outdoors, the deodorizing function of the fragrance component is sustained during the outing, preventing discomfort caused by unpleasant odors adhering to the skin and clothing.

[0010] In the blood-sucking insect 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 brassirate, cyclopentadecanol, menthone, limonene, citronellol, citronellal, 1,8-cineole, α-terpineol, borneol, camphor, patchouli alcohol, β-himacalene, benzyl acetate, benzyl alcohol, geranyl formate, eugenol, bisabolol oxide A, and α-pinene.

[0011] According to this blood-sucking insect repellent composition, the inclusion of the above-mentioned fragrance components enhances the synergistic effect between the insect repellent components and the fragrance components, thereby improving the duration of the deodorizing function.

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

[0013] According to this blood-sucking insect repellent composition, the amount of fragrance components is within an appropriate range, so that unpleasant odors adhering to the skin or clothing are masked by the fragrance, and sufficient deodorizing effect can be obtained.

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

[0015] With this blood-sucking insect repellent composition, because the blending ratio is within an appropriate range, the repellent function against blood-sucking insects by the insect repellent component can be fully exerted, while the synergistic effect between the insect repellent component and the fragrance component can be fully exerted, and the deodorizing function of the fragrance component can be sustained for a long period of time.

[0016] The characteristic configuration of the blood-sucking insect repellent method according to the present invention, which solves the above problems, is as follows: A method for repelling blood-sucking insects using any one of the aforementioned blood-sucking insect repellent compositions, A spraying step of spraying the blood-sucking insect repellent composition onto the skin or clothing to be treated, A modification step of changing the location where the blood-sucking insect repellent composition is sprayed onto the skin or clothing, The purpose is to include it.

[0017] According to the present invention's method for repelling blood-sucking insects, by spraying the blood-sucking insect repellent composition onto the skin or clothing to be treated, and further changing the spraying location on the skin or clothing, it is possible to impart insect repellent effect and deodorizing function to the entire skin or clothing. The blood-sucking insect repellent composition containing specific insect repellent components and fragrance components allows the insect repellent component to repel blood-sucking insects, and the synergistic effect of the insect repellent component and fragrance component allows the deodorizing function of the fragrance component to last for a long period of time. Therefore, by simply spraying the blood-sucking insect repellent composition of the present invention onto the skin or clothing once according to the present invention's method for repelling blood-sucking insects before going out, it is possible to repel blood-sucking insects while out and about, as well as have a lasting deodorizing function from the fragrance component, preventing discomfort caused by unpleasant odors adhering to the skin or clothing. [Modes for carrying out the invention]

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

[0019] <Insect repellent composition for blood-sucking insects> The blood-sucking insect repellent composition of the present invention contains a fragrance component and an insect repellent component.

[0020] One of the main components of the blood-sucking insect repellent composition of the present invention is ethyl 3-(N-butylacetamide)propionate (hereinafter referred to as "IR3535"), picaridin (also known as "1-methylpropyl 2-(2-hydroxyethyl)-1-piperidine carboxylate"), p-menthane-3,8-diol (hereinafter referred to as "PMD"), and N,N-diethyltoluamide (hereinafter referred to as "DEET"). These can be used individually, but may also be used in the form of a mixture of two or more. IR3535, picaridin, PMD, and DEET are volatile and have a high repellent effect against blood-sucking insects (excluding lice), especially adult mosquitoes, black flies, horseflies, midges, ticks, predatory mites, flour mites, or cat fleas. They also have a repellent effect against nuisance insects such as midges, drain flies, and ants. As described above, IR3535, picaridin, PMD, and DEET have conventionally been used as insect repellents. However, while the inventors prepared various blood-sucking insect repellent compositions using IR3535, picaridin, PMD, and DEET, they newly discovered that IR3535, picaridin, PMD, and DEET, in addition to the aforementioned blood-sucking insect repellent effect, also possess a sustained function that prolongs the deodorizing function of specific fragrance components described later. The blood-sucking insect repellent composition of the present invention, when applied to the skin or clothing by spraying or other means, volatilizes the insect repellent components from the skin or clothing being worn, preventing the approach or contact of blood-sucking insects. This prevents blood-sucking by blood-sucking insects while providing long-lasting deodorization of unpleasant odors attached to the skin or clothing. On clothing being worn, the volatilization of the insect repellent components is promoted by the user's body temperature, thus more effectively preventing the approach or contact of blood-sucking insects. Furthermore, it can deodorize the unpleasant odors that attract blood-sucking insects such as mosquitoes, thus exhibiting a synergistic repellent effect. IR3535, picaridin, PMD, and DEET are highly safe for humans, so they can be sprayed directly onto skin such as arms and legs. In addition, IR3535, picaridin, and PMD are less likely to cause stains or discoloration on textile products and are almost odorless. Therefore, the blood-sucking insect repellent composition of the present invention can be used on clothing without worrying about damage to clothing or the odor of the insect 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 such a range, by attaching the blood-sucking pest repellent composition to the skin or clothing through spraying or the like, while exerting a repellent effect against blood-sucking pests, a synergistic effect with specific fragrance components described later can be achieved, and the sustainability of the deodorizing function can be improved.

[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 does not have an electron conjugation part other than the electron conjugation part derived from a benzene ring, a benzoic acid ester structure, or a salicylic acid ester structure, has 6 to 18 carbon atoms, a molecular weight of 98 to 270, has carbon atoms, hydrogen atoms, and oxygen atoms, and does not have sulfur atoms, nitrogen atoms, and halogen atoms. Such a compound has an excellent deodorizing function of masking malodors (such as sweat odor, middle sebum odor, and aging odor) attached to the skin or clothing with fragrance, and due to the synergistic effect with IR3535, ikaridin, PMD, and DEET used as pest repellent components in the present invention, its deodorizing function can be sustained for a long time.

[0056] [ka] Examples include α-pinene (hereinafter referred to as "compound i"), as shown by [formula].

[0057] Compounds A-Z and a-i described above may be used individually or in combination. They may also be incorporated as essential oils containing these fragrance components, such as peppermint 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 this invention, even if incorporated as an essential oil, if the above fragrance components are present in the essential oil at a concentration of 1.0% by mass or more, they are defined as being incorporated as individual fragrance components. The fragrance component content is preferably 0.1-2.0 w / v%. Within this range, sufficient deodorizing properties can be obtained by masking unpleasant odors adhering to the skin and clothing.

[0058] In the blood-sucking insect repellent composition of the present invention, it is preferable that the fragrance component contains menthone, limonene, terpineol, linalool, or linalyl acetate, as this results in a synergistic effect in the blood-sucking insect repellent function. In particular, it is more preferable to include linalool and linalyl acetate, as the synergistic effect of the deodorizing function between the insect repellent component and the fragrance component is further enhanced, and the duration of the deodorizing function by the fragrance component can be further improved. Furthermore, it is preferable to adjust the weight ratio of linalool to linalyl acetate to 0.5 to 2.0.

[0059] In the blood-sucking insect repellent composition of the present invention, the mixing ratio (a / b) of the fragrance component (a) to the insect repellent component (b) is preferably adjusted to 0.01 to 1.5 by weight. When the mixing ratio (a / b) is within this range, the synergistic effect between the insect repellent component and the fragrance component is enhanced, and the deodorizing function of the fragrance component lasts for a long period of time.

[0060] In addition to the above components, the blood-sucking insect repellent composition of the present invention may also contain, as appropriate, stabilizers for insect repellent components, antifungal agents targeting molds and fungi, antibacterial agents, fungicides, antistatic agents, defoaming agents, cooling agents, etc. For example, when IR3535 is used as the insect repellent component, triethanolamine can be added. By including triethanolamine, the stability of IR3535, which is easily decomposed under acidic conditions, can be improved, and the amount of IR3535 can not be excessively reduced even when the blood-sucking insect repellent composition is stored for a long period of time. The amount of triethanolamine in the blood-sucking insect repellent composition is preferably 0.05 to 0.2 w / v%. Within this range, the stability of IR3535 can be sufficiently improved, so the blood-sucking insect repellent composition is easy to use and has excellent long-term storage properties. When IR3535 is used as the insect repellent component, it is preferable to use menthol in combination with triethanolamine. The menthol content in the blood-sucking insect repellent composition is preferably 0.1 to 1.5 w / v%. Within this range, the synergistic effect of triethanolamine and menthol can further improve the stability of IR3535 and also provide a cooling sensation. On the other hand, when picaridin, PMD, or DEET are used as insect repellent components, menthol can be added. The menthol content in the blood-sucking insect repellent composition is preferably 0.1 to 1.5 w / v%. Within this range, the stability-improving effect of menthol can further improve the stability of picaridin, PMD, or DEET and also provide a cooling sensation. Although menthol has conventionally been used as a fragrance, the inventors have prepared various blood-sucking insect repellent compositions and found that when the menthol content is within the above range, menthol does not exhibit a deodorizing function that eliminates unpleasant odors adhering to skin or clothing. Furthermore, even when the menthol content was increased beyond the above range to a degree that exhibited deodorizing function, the deodorizing function did not persist due to IR3535, picaridin, PMD, and DEET. For this reason, the fragrance component of the present invention does not contain menthol.Examples of fungicides, antibacterial agents, and disinfectants include hinokitiol, 2-mercaptobenzothiazole, 2-(4-thiazolyl)bentwimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, triforine, 3-methyl-4-isopropylphenol, and orthophenylphenol.

[0061] The blood-sucking insect repellent composition of the present invention is prepared by blending the above-mentioned components in appropriate weight ratios and adding ketone solvents such as acetone, methyl ethyl ketone, diethyl ketone, and cyclohexanone; alcohol solvents such as methanol, ethanol, butanol, 1-propanol, 2-propanol, and 1-butanol; glycol solvents such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, 1,3-butylene glycol, and dipropylene glycol; glycol ether solvents such as diethylene glycol monomethyl ether, diethylene glycol monobutyl ether, triethylene glycol monomethyl ether, and phenoxyethanol; hydrocarbon solvents such as toluene, xylene, n-hexane, n-paraffin, and isoparaffin; ester 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. In particular, the addition of water and alcohols, or water and glycol ethers, is preferred. As for alcohols, lower alcohols with 2 to 3 carbon atoms are preferred, and ethanol is particularly preferred. Glycol monoethers are preferred among glycol ethers, and phenoxyethanol is particularly preferred.

[0062] <Product form> The present invention's blood-sucking insect repellent composition can take the form of a spray, gel, powder, or sheet. Each product form will be described below.

[0063] <Spray products for controlling blood-sucking insects> A preferred product form of the blood-sucking insect repellent composition of the present invention is a spray product. For example, a spray product for controlling blood-sucking insects is constructed by sealing the blood-sucking insect repellent composition of the present invention and, if necessary, a propellant in a spray container. The spray container is preferably equipped with a push-down spray or a trigger sprayer. This allows the blood-sucking insect repellent composition to diffuse when sprayed, resulting in a substantially uniform amount of the blood-sucking insect repellent composition adhering to the skin or clothing being treated. Furthermore, it is possible to apply a precise amount of the blood-sucking insect repellent composition to the skin or clothing being treated according to the number of sprays.

[0064] <Gel products for controlling blood-sucking insects> A preferred product form of the blood-sucking insect repellent composition of the present invention is a gel product. For example, a gel product for controlling blood-sucking insects is constructed by sealing the blood-sucking insect repellent composition, a gel base, and a gelling agent in a gel container. Examples of gel bases include water-soluble polymers such as carboxyvinyl polymer, polyvinyl alcohol, and polyvinylpyrrolidone; acrylic acid 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. Carboxyvinyl polymer is particularly preferred. Examples of gelling agents include amines such as triethanolamine and tetrahydroxypropylethylenediamine; sodium hydroxide; and aminomethylpropanol.

[0065] <Coating products for controlling blood-sucking insects> A preferred product form of the blood-sucking insect repellent composition of the present invention is a coating product. For example, a coating product for controlling blood-sucking insects is constructed by sealing the blood-sucking insect repellent composition of the present invention in a drop pump container. Examples of coating products include creams, liquids, emulsions, aqueous solutions, microemulsions, and the like.

[0066] <Powder product for controlling blood-sucking insects> A preferred product form of the blood-sucking insect repellent composition of the present invention is a powder product. For example, a powder product for controlling blood-sucking insects is constructed by sealing the blood-sucking insect repellent composition, a moisture-retaining agent, and an oil-absorbing agent in a powder container. Examples of moisture-retaining agents include talc, kaolin, and bentonite, with talc being particularly preferred. Examples of oil-absorbing agents include silica compounds such as anhydrous silicic acid, calcium silicate, hydrophobic silica, and diatomaceous earth, with anhydrous silicic acid being particularly preferred due to its high oil-absorbing effect.

[0067] <Insect-sucking insect control sheet products> A preferred product form of the blood-sucking insect repellent composition of the present invention is a sheet product. For example, a sheet product for controlling blood-sucking insects is constructed by impregnating a sheet-like substrate with the blood-sucking insect repellent composition of the present invention. Methods for impregnating a sheet-like substrate with the blood-sucking insect repellent composition include, for example, spraying the blood-sucking insect repellent composition onto the sheet-like substrate using a spray, air gun, etc., directly applying the blood-sucking insect repellent composition onto the sheet-like substrate using a slit-type nozzle, etc., or impregnating the sheet-like substrate with the blood-sucking insect repellent composition after it has been placed in a packaging container. As the sheet-like substrate, any of natural fibers, synthetic fibers, and nonwoven and woven fabrics blended therefrom can be used. Specifically, examples include nonwoven and woven fabrics made from cupro, rayon, acetate, acrylic, polyester, polyethylene, polypropylene, polyurethane, polyamide, cotton, and blends thereof, as well as wet and dry pulp sheets, and pulp sheets reinforced with thermoplastic resins (polyethylene, polypropylene, polyethylene terephthalate, etc.).

[0068] <Methods for deodorizing clothing> The blood-sucking insect repellent composition of the present invention can be used, for example, to deodorize clothing by spraying it onto clothing, such as a spray product for controlling blood-sucking insects. Specifically, this can be done by the user pressing the spray head of the spray product to spray the blood-sucking insect repellent composition onto clothing such as clothes or hats, or by grasping the trigger of the spray product and spraying the blood-sucking insect repellent composition onto clothing such as clothes or hats. As a result, the blood-sucking insect repellent composition adheres to the surface of the clothing. The blood-sucking insect repellent composition of the present invention uses IR3535, picaridin, PMD, and DEET as insect repellent components, which have high safety for the human body, so it can also be sprayed onto clothing while it is being worn. When the blood-sucking insect repellent composition is sprayed, it provides an excellent repellent effect against blood-sucking insects and a long-lasting deodorizing function. As a result, it can prevent blood-sucking insects from approaching or coming into contact with clothing, thus preventing blood-sucking, while also deodorizing unpleasant odors attached to clothing. It can also be sprayed directly onto the skin of the arms and legs.

[0069] <Methods to repel blood-sucking insects> The present invention provides a method for repelling blood-sucking insects, comprising a spraying step of spraying a blood-sucking insect repellent composition containing insect repellent components and fragrance components onto the skin or clothing to be treated, and a modification step of changing the spraying location of the blood-sucking insect repellent composition on the skin or clothing to ensure sufficient and sustained insect repellent and deodorizing effects on the skin or clothing. In the present invention's blood-sucking insect repellent and deodorizing method, the user should spray while appropriately moving the blood-sucking insect control spray product so that the blood-sucking insect repellent composition adheres to the entire surface of the skin or clothing. For example, by thoroughly spraying areas of clothing where odor is particularly noticeable (e.g., underarms, around the neck, around the legs), an effective insect repellent effect and a sustained deodorizing effect can be simultaneously imparted to the clothing. Thus, by implementing the blood-sucking insect repellent and deodorizing method of the present invention, an insect repellent effect and a sustained deodorizing effect can be simultaneously imparted to the skin or clothing in a single treatment. Furthermore, skin and clothing treated with the insect-repellent method of the present invention will have a long-lasting deodorizing function due to the synergistic effect of the insect-repellent component and the fragrance component described later. For example, even when spending the whole day outdoors, insect-repellent insects will not approach, and you can be comfortable for extended periods without worrying about odors.

[0070] The blood-sucking insect repellent composition according to the present invention, by combining an insect repellent component with a specific fragrance component, can sustain the deodorizing function of the fragrance component for a long period of time due to the synergistic effect of the insect repellent component and the fragrance component. The duration of the deodorizing function varies depending on the combination of the insect repellent component and the fragrance component, the mixing ratio of the two components, and the usage conditions of the blood-sucking insect repellent composition, but it is quite possible to sustain the deodorizing function for approximately half a day to a full day. Therefore, by performing a spray treatment before going out according to the blood-sucking insect repellent method of the present invention using this blood-sucking insect repellent composition, the deodorizing function of the fragrance component can be sustained for, for example, about 12 hours of going out, preventing discomfort caused by unpleasant odors adhering to the skin and clothing. [Examples]

[0071] To confirm the persistence of the deodorizing function of the blood-sucking insect repellent composition of the present invention, blood-sucking insect repellent compositions possessing the characteristic configuration of the present invention (Examples 1 to 60) were prepared and deodorizing function confirmation tests were conducted. For comparison, blood-sucking insect repellent compositions without the characteristic configuration of the present invention (Comparative Examples 1 to 61) were prepared and similar deodorizing function confirmation tests were conducted. In Examples 1 to 60 and Comparative Examples 1 to 61, the unit of weight is given as "g," but it is possible to scale up by any ratio. That is, the unit "g" can be read as "parts by weight."

[0072] <Examples 1-21> Blood-sucking insect repellent compositions (Examples 1-21) were prepared according to the following formulation 1, which uses IR3535 as an insect repellent component.

[0120] [Table 1]

[0121] [Table 2]

[0122] [Deodorizing function confirmation test] Deodorizing function tests were conducted for sweat odor, middle-aged body odor, and age-related body odor. For sweat odor, a test cotton cloth (5cm x 5cm cotton cloth (Kinkin No. 3)) was placed in a tall petri dish (outer diameter 75mm, height 60mm), and an appropriate amount of isovaleric acid (manufactured by Nacalai Tesque Co., Ltd.) ethanol solution was sprayed as the test odor using a spray vial. For middle-aged body odor, a test cotton cloth was placed in a tall petri dish, and an appropriate amount of diacetyl (manufactured by Nacalai Tesque Co., Ltd.) ethanol solution was sprayed as the test odor using a spray vial. For age-related body odor, a test cotton cloth was placed in a tall petri dish, and an appropriate amount of 2-nonenal (manufactured by Tokyo Chemical Industry Co., Ltd.) ethanol solution was sprayed as the test odor using a spray vial.

[0123] For body odor, 0.03 mL of the test solutions from Examples 1-60 and Comparative Examples 1-61 were sprayed into each test cotton cloth that had been treated with an added malodorous odor using a spray vial. The odor in the petri dish was evaluated immediately after spraying, 3 hours later, and 12 hours later. For middle-aged body odor and age-related odor, 0.03 mL of the test solutions from Examples 1-56 and Comparative Examples 1-57 were sprayed into each test cotton cloth that had been treated with an added malodorous odor using a spray vial. The odor in the petri dish was evaluated immediately after spraying, 3 hours later, and 12 hours later. The odor was evaluated by five testers using the following 5-point odor intensity scale, and the average score was calculated. An average score of 0 or more and less than 2 was marked with ○, 2 or more and less than 3 with △, and 3 or more and 4 or less with ×.

[0124] In Example 1, to confirm the effect of isopropylmethylphenol (IPMP), menthol, and triethanolamine (TEA) on this test, the same test was conducted with samples that did not contain any of these components, and with samples containing one or two of these components. As a result, it was confirmed that these components did not affect the results of this test. 0: No scent detected 1: I can faintly feel it. 2: Feels weak 3: Clearly I feel 4: I feel it strongly

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

[0126] [Table 3]

[0127] [Table 4]

[0128] Tables 5 and 6 show the results of the deodorizing function test against middle-aged body odor.

[0129] [Table 5]

[0130] [Table 6]

[0131] Tables 7 and 8 show the results of the deodorizing function test against age-related body odor.

[0132] [Table 7]

[0133] [Table 8]

[0134] The results of the deodorizing function confirmation test showed that the blood-sucking insect repellent compositions possessing the characteristic configuration of the present invention, whether Examples 1-27 containing IR3535 as an insect repellent component or Examples 28-60 containing picaridin as an insect repellent component, exhibited excellent deodorizing properties against sweat odor, middle-aged body odor, and age-related body odor even 12 hours after spraying the test solution. From this, it is considered that by spraying the blood-sucking insect repellent composition possessing the characteristic configuration of the present invention onto the skin or clothing before going out, the deodorizing function of the fragrance component will last for about 12 hours while out, preventing discomfort caused by unpleasant odors adhering to the skin or clothing.

[0135] On the other hand, the blood-sucking insect repellent compositions of Comparative Examples 1-21 and 57-61, which do not contain insect repellent components, contain the same fragrance components as Examples 1-27, which contain IR3535 as an insect repellent component, and Examples 28-60, which contain picaridin as an insect repellent component. However, they only showed deodorizing properties against sweat odor, middle-aged body odor, and age-related body odor up to 3 hours after spraying the test solution, and did not show sufficient deodorizing properties after 12 hours.

[0136] Comparative Example 22's blood-sucking insect repellent composition contained IR3535 as an insect repellent component, similar to Examples 1-27, and Comparative Example 23's blood-sucking insect repellent composition contained picaridin as an insect repellent component, similar to Examples 28-56. However, neither Comparative Examples 22 nor 23 contained any fragrance components. These blood-sucking insect repellent compositions of Comparative Examples 22 and 23 showed no deodorizing effect against sweat odor, middle-aged body odor, or age-related body odor. From this, it was confirmed that IR3535 and picaridin, as insect repellent components, do not have deodorizing properties on their own. Although the insect repellent components IR3535 and picaridin do not possess deodorizing properties on their own, the deodorizing function lasted longer in the blood-sucking insect repellent compositions of Examples 1 to 56, which simply contained insect repellent components added to these components, compared to the blood-sucking insect repellent compositions of Comparative Examples 1 to 21. This is thought to be because the insect repellent components have some synergistic effect with the specific fragrance components defined in the present invention.

[0137] Furthermore, Comparative Examples 24-56, which used compounds having electron-conjugated moieties other than those derived from a benzene ring, benzoic acid ester structure, or salicylic acid ester structure as fragrance components, only showed deodorizing properties against sweat odor, middle-aged body odor, and age-related body odor up to 3 hours after spraying the test solution, and did not show sufficient deodorizing properties after 12 hours. The fact that the deodorizing function did not last for a long time even when IR3535 was included as an insect repellent component (Comparative Examples 24-34) and when picaridin was included as an insect repellent component (Comparative Examples 35-45) is thought to be because the specific fragrance components defined in the present invention were not used, and therefore a synergistic effect between the insect repellent component and the fragrance component could not be obtained.

[0138] From the above results, it was confirmed that the blood-sucking insect repellent compositions (Examples 1-60) possessing the characteristic configuration of the present invention achieve a synergistic effect between the insect repellent component and the fragrance component through the combination of a specific insect repellent component and a specific fragrance component, and that the deodorizing function of the fragrance component lasts for a long period of time.

[0139] [Outdoor Performance Verification Test 1] The blood-sucking insect repellent composition of the present invention was prepared as a pump spray product (Examples 61-64), and its performance outdoors was confirmed by actually spraying it onto clothing.

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

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

[0142] <Example 63> A blood-sucking insect repellent composition was prepared by mixing 0.9 g (0.9 w / v%) of linalool, 15.0 g (15.0 w / v%) of picaridin, 40 g (40 w / v%) of purified water, and the remainder (balance) of anhydrous ethanol to a total volume of 100 mL. The mixing ratio (a / b) of the fragrance component (a) to the insect repellent component (b) of this blood-sucking insect repellent composition was 0.06 by weight. The prepared blood-sucking insect repellent composition was filled into a push-down pump spray container to obtain blood-sucking insect repellent spray product 3.

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

[0144] Four panelists (one man each in his 30s, 40s, 50s, and 60s) each selected one spray from the above blood-sucking insect repellent spray products 1-4 (Examples 61-64) and sprayed it on their clothing. They then freely strolled around the park from 10:00 AM to 4:00 PM on a sunny day. None of the four panelists were bitten by mosquitoes or other blood-sucking insects during their stroll, and they were able to spend their time comfortably without being bothered by any odor from their clothing. In particular, blood-sucking insect repellent spray product 4 of Example 64, which used "linalool" and "linalyl acetate" as fragrance components, showed significantly superior repellent and deodorizing effects against blood-sucking insects compared to blood-sucking insect repellent spray products 1-3 of Examples 61-63, which used other fragrance components. The fact that this combination of "linalool" and "linalyl acetate" exhibits a particularly high effect is a new finding discovered by the inventors through trial and error in combining various fragrance components.

[0145] [Outdoor Performance Verification Test 2] The blood-sucking insect repellent composition of the present invention was prepared as a pump spray product (Example 65), and its performance outdoors was confirmed by actually spraying it onto clothing.

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

[0147] Two testers (one man in his 30s and one man in his 50s) sprayed the above-mentioned blood-sucking insect repellent spray product 5 onto their clothing and freely strolled around the park from 10 a.m. to 16 p.m. on a sunny day. Neither of the two testers was bitten by mosquitoes or other blood-sucking insects during their stroll, and they were able to spend their time comfortably without being bothered by any odor from their clothing. [Industrial applicability]
