Description

  The present invention relates to a flying insect repellent product and a flying insect repellent method.

  Conventionally, a method of applying a repellent containing diet (N, N-diethyltoluamide) to the skin surface against flying pests such as mosquitoes, moths, chironomids and flies has been widely used. However, since diet is somewhat less volatile than ordinary fragrance ingredients, it cannot be expected to have a spatial repellent effect. On the other hand, room temperature volatile insecticidal components, such as pyrethroid-based empentrin, can be volatilized into the space to achieve a repelling effect against flying insects, but there are few situations where the use of room temperature volatile insecticidal components is avoided. Exist.

  Thus, several attempts have been made to use volatile natural essential oils and their components as repellent components. For example, it is well known that citronella oil and its main component citronellal have a repellent effect on mosquitoes, and candles containing citronella oil as an active ingredient are commercially available in the United States. However, the method of dissipating citronellal using the heat of the candle has poor volatilization efficiency of citronellal and cannot provide a practical repellent effect.

  Japanese Patent Application Laid-Open No. 2002-173407 (Patent Document 1) describes a flying pest repellent containing, as an active ingredient, a natural essential oil selected from orange oil, cassia oil and the like in addition to citronella oil. Solvents to be used include alcohols such as methyl alcohol and ethyl alcohol, esters such as diethyl phthalate and isopropyl myristate, aliphatic hydrocarbons such as hexane, kerosene and paraffin, aromatic hydrocarbons, ethers, etc. There are many types.

  In addition, Japanese Patent Application Laid-Open No. 2003-201203 (Patent Document 2) discloses that pest repellent component (A) is citronellal and one or more selected from terpineol, menthol, limonene, geraniol, citronellol, camphene and the like. And a pest repellent volatilization composition in which the content of citronellal in the pest repellent component (A) is 2 to 10% by mass. However, although these repellents urge the attention to natural products and safety, their repellent effects are inferior in sustainability and are not always satisfactory.

  Furthermore, Japanese Patent Application Laid-Open No. 61-289002 (Patent Document 3) proposes “a repellent for arthropods, molluscs and reptiles containing glycol ethers as an active ingredient”. Patent Document 3 describes that glycol ethers have an excellent repellent effect on cockroaches and mites, but the effect is far from sufficient and does not mention any repellent effect against flying insects. Absent.

  Thus, useful flying insect repellent fragrance compositions aimed at improving the flying insect pest repellent effect and, in addition to this, the sustainability of fragrance are not yet known, and their development is required.

  By the way, it is known that silicone rubber is excellent in adsorptivity and gas permeability, is stable in physical properties, and has excellent fragrance release properties. Utilizing these properties, a fragrance containing a fragrance in silicone rubber is commercially available. When the fragrance is contained in the silicone rubber, the silicone compound or liquid silicone and the fragrance are usually mixed and vulcanized (crosslinked) using a vulcanizing agent such as sulfur or the like. However, separation of the fragrance from the rubber polymer or additive is likely to occur during kneading, and furthermore, chemical changes such as decomposition or modification of the fragrance due to heat or sulfur during molding result in having aromaticity and physical properties. It was difficult to obtain a stable molded product.

  Therefore, as means for solving such a problem, JP-A-8-311216 (Patent Document 4) and JP-A-2011-26462 (Patent Document 5) do not knead the fragrance before molding the silicone rubber, A method of adding a fragrance after silicone rubber molding is employed. However, these documents do not mention compatibility between the properties of the fragrance composition and the silicone rubber, and do not necessarily apply to functionally different flying insect repellent fragrance compositions.

Japanese Patent Laid-Open No. 2002-173407 JP 2003-201203 A JP-A 61-289002 Japanese Patent Laid-Open No. 8-31216 JP 2011-26462 A

  Hereinafter, an embodiment relating to a flying insect repellent product of the present invention will be described. The flying pest repellent method of the present invention will be described together in the description of the flying pest repellent product. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

  The flying pest repellent product of the present invention is a flying pest containing a flying pest repellent fragrance component in a rubber molded body containing silicone rubber and having a hardness of 50 degrees or less (hereinafter sometimes abbreviated as “rubber molded body”). A repellent fragrance composition is retained. As the flying insect repellent fragrance component, a specific type suitable for a rubber molded body is used. Details of the flying pest repellent component will be described later.

  The silicone rubber used for the molded article has excellent gas permeability, is stable in physical properties, and has excellent properties such as perfume adsorption and divergence. This is thought to be because the molecular structure of the fragrance is likely to enter gaps in the molecular structure of rubber in which the main chain is composed of carbon and the fragrance molecules are three-dimensionally crosslinked. In order to take advantage of the characteristics of silicone rubber, it is preferable to adjust the hardness of the rubber molded body to 50 degrees or less. For example, silicone rubber having a hardness of 50 degrees or less is used as a raw material for a rubber molded body. Thereby, the hardness of the completed rubber molding becomes 50 degrees or less. When the hardness of the rubber molded body is 50 degrees or less, the molecular structure of the silicone rubber does not become too dense, so that the fragrance molecules easily enter the gaps in the molecular structure of the rubber. In addition, the hardness of the rubber molded body is measured by a method or apparatus in accordance with Japanese Industrial Standard (JIS K6253). In the present invention, the hardness of the rubber molded body is measured using a durometer conforming to the above standard.

  Silicone rubber can be used regardless of the type, such as room temperature curing type, heat curing type, condensation type, addition type, etc. Usually, vulcanizing agents such as sulfur, additives such as silica, etc. are used in silicone compounds or liquid silicones. Is then vulcanized (crosslinked) and molded. The amount of volatilization of the flying insect repellent composition to be added later can be controlled by adjusting the crosslinking density of the silicone rubber or by adjusting the amount of silicone oil or filler used as an additive.

  The rubber molded body used in the present invention may contain other types of rubber. For example, in the case where fluorine rubber is included in addition to silicone rubber, improvement in durability is expected.

The rubber molded body is configured as an annular rubber molded body having a stretchable ring portion into which a part of a human body or an object is inserted or attached. A ring-shaped rubber molded body holding a flying insect repellent fragrance composition, a part of a human body such as a wrist or ankle, a handle such as a buggy or a bicycle, a handle such as a bag, a rucksack or a bag, a hat, shoes When inserted into or attached to an object such as a string, the flying insect repellent fragrance component gradually evaporates from the surface of the annular rubber molded body. For example, in the case of a flying pest repellent product whose volatilization state lasts for 5 to 15 hours, in order to maintain such volatilization performance, the average volatilization amount of the flying pest repellent component is the total surface area of the annular rubber molded body. It is preferably 0.05 to 1.0 mg / cm ² · h. When the average volatilization amount of the flying insect repellent component is within this range, the bleeding of the flying insect repellent component in the annular rubber molded body proceeds stably and smoothly over 5 to 15 hours, preferably 8 to 12 hours. To do. If the average volatilization amount of the flying insect repellent component is less than 0.05 mg / cm ² · h, the flying insect repellent effect is insufficient, and the average volatilization amount of the flying insect repellent component is 1.0 mg / cm ² · h. If it exceeds, the duration of the repellent effect will be shortened, and there is an unavoidable possibility that the amount of flying pest repellent fragrance component or flying pest repellent perfume composition will be excessively retained in the silicone rubber molded body and cause stickiness on the surface . In the present invention, the average volatilization amount refers to an average value for a time zone showing a volatilization amount of 0.02 mg / cm ² · h or more.

  The shape of the rubber molded body is one string-like body (wire diameter: 1 to 3 mm, length: connected) so that it can be easily inserted into or attached to a part of a human body such as a wrist or ankle or the above-mentioned object. About 10 to 20 cm) and having a figure or character formed thereon is used. 1 to 4 are schematic views of a silicone rubber molded body 1 simulating an animal that is a character. In each figure, (a) represents the rubber molded body 1 when not mounted, and (b) represents a state where the rubber molded body 1 is mounted on the wrist 2. The silicone rubber molded body 1 is an annular rubber molded body having a stretchable ring portion into which a part of a human body or an object is inserted or attached. The contour of the ring portion has a figure or character profile as shown in each of FIGS. Examples of graphics or characters include, but are not limited to, animal series, insect series, vehicle series, alphabet series, and the like. When the original shape of the rubber molded body 1 is partially expanded and attached to a wrist, ankle, or the like, at least 20%, preferably 30% of the portion forms an attachment state separated from the skin such as the wrist or ankle. Thus, it is preferable to expand and contract. This is because the separated portion not only contributes to the improvement in volatility of the repellent fragrance component, but it is desirable to avoid contact with the skin as much as possible although it is a fragrance component. Each of FIG. 1 to FIG. 4B shows a separation portion 3 formed by separating a part of the rubber molded body 1 from the wrist 2.

  The flying insect pest repellent product of the present invention is mainly composed of a figure or a character formed from one string-like body. As shown in FIG. 4, a rubber molded body from one place or several places of this string-like body. May be branched to form the branch portion 4 to constitute an accessory. In this way, the decorativeness is imparted and the weight of the rubber molded body is increased and the amount of the flying insect repellent fragrance component can be increased. As a result, the flying insect repellent product of the present invention attached to the wrist, ankle, etc. The advantage is that the number can be reduced. The shape and size of the accessory are not particularly limited as long as the fragrance component volatility of this part is not excessive or excessive compared to the figure or the main part of the character.

  The flying pest repellent fragrance composition used for the flying pest repellent product of the present invention uses substantially no pesticide component and uses the fragrance component as a flying pest repellent component. Such a fragrance component is referred to as a “flying insect repellent fragrance component”. The flying insect pest repellent component contains the following components (a) and (b).

As the component (a), the general formula (I);
_{CH 3 -COO-R1 ··· (I} )
[R1: an alcohol residue having 6 to 12 carbon atoms]
An acetate compound as a single substance or a mixture represented by:
Examples of the component (b) include monoterpene alcohols and / or aromatic alcohols having 10 carbon atoms.

Among the flying pest repellent fragrance components, as the component (a), the general formula (II);
_{R2-CH 2 -COO-CH 2} -CH = CH 2 ··· (II)
[R2: C4-C7 alkyl group, alkoxy group, cycloalkyl group, cycloalkoxy group, or phenoxy group]
It is also possible to include the allyl ester compound as a single substance or a mixture represented by: In this case, the component (a) is at least one selected from acetate ester compounds and allyl ester compounds.

  The flying pest repellent fragrance composition preferably further contains glycol and / or glycol ether having a vapor pressure of 0.2 to 20 Pa at 20 ° C. as a repellent effect sustained component at the time of volatilization of the flying pest repellent component.

  The blending amount (retention amount) of the flying insect pest repellent component or the flying insect repellent perfume composition on the rubber molded product is appropriately determined depending on the intended use of the flying insect repellent product, the period of use, the type and specifications of the rubber molded product, etc. Just decide. For example, in the case of a repellent product that is used for 8 to 12 hours per time, the product weight is usually about 0.5 to 2.5 g, and the flying insect repellent component is 5 to 50 mg per rubber molded body (that is, It is appropriate to hold in the range of 1 to 10% by mass.

Further, according to the test results of the present inventors described later, it has been found that the volatilization state of the flying insect repellent fragrance component from the rubber molded body is affected by the formulation of the flying insect repellant fragrance composition. In the flying insect pest repellent fragrance composition used in the present invention, glycol and / or glycol ether blended as a repellent effect sustaining component at the time of volatilization greatly contributes to stabilization of volatilization from the silicone rubber molded body of the fragrance component. On the other hand, in the case of a flying pest repellent composition that does not contain glycol and / or glycol ether, the initial volatilization amount tended to increase somewhat (resulting in a duration of less than 5 hours or an average The volatilization amount could exceed 1.0 mg / cm ² · h).

  The flight pest repellent component contained in the flight pest repellent composition used in the flight pest repellent product of the present invention will be specifically described below.

  Among the flying pest repellent components, specific examples of the acetate compound represented by the general formula (I) as the component (a) include p-tert-butylcyclohexyl acetate, o-tert-butylcyclohexyl acetate, p- tert-pentylcyclohexyl acetate, tricyclodecenyl acetate, benzyl acetate, phenylethyl acetate, styryl acetate, anisyl acetate, cinnamyl acetate, terpinyl acetate, dihydroterpinyl acetate, linalyl acetate, ethyl linalyl acetate, Citronellyl acetate, geranyl acetate, neryl acetate, bornyl acetate, isobornyl acetate and the like. These acetate compounds may be used alone or in any combination.

  Specific examples of the allyl ester compound represented by the general formula (II) as the component (a) among the flying insect pest repellent components include allyl hexanoate, allyl heptanoate, allyl octanoate, allyl isobutyloxy Examples include acetate, allyl n-amyloxyacetate, allylcyclohexylacetate, allylcyclohexylpropionate, allylcyclohexyloxyacetate, and allylphenoxyacetate. These allyl ester compounds may be used alone or in any combination. These allyl ester compounds can also be used in any combination with the above-mentioned acetate ester compounds.

  Specific examples of the monoterpene alcohol and / or the C10 aromatic alcohol as the component (b) among the flying insect repellent fragrance components include terpineol, geraniol, dihydromyrsenol, borneol, menthol, citronellol, and nerol. , Linalool, ethyl linalool, thymol, eugenol, and p-menthane-3,8-diol. These monoterpene alcohols and / or aromatic alcohols having 10 carbon atoms may be used alone or in any combination.

  In the flying insect repellent product of the present invention, it is preferable to use the component (a) and the component (b), which are the flying insect repellent component. In this case, when the blending ratio of the component (a) to the component (b) is set to 0.1 to 2.0 times, a result of intensive studies by the present inventors that a particularly excellent flying insect repellent result can be obtained. It was recognized more.

In the flying pest repellent product of the present invention, as a flying pest repellent fragrance component, a fragrance component other than the above, for example, other ester compounds such as benzyl benzoate, cinnamyl formate, geranyl formate, and monoterpene carbonization such as limonene Monoterpene ketones such as hydrogen, menthone, carvone, pregon, camphor and damascon, monoterpene aldehydes such as citral, citronellal, neral, and perilaldehyde, phenylethyl alcohol, diphenyl oxide, indole aroma, etc. may be added as appropriate. . Furthermore, various essential oils containing the above perfume ingredients, e.g., jasmine oil, neroli oil, base Rugamotto oil, orange oil, geranium oil, petitgrain oil, lemon oil, citronella oil, lemon grass oil, cinnamon oil, eucalyptus oil, You may add lemon eucalyptus oil, thyme oil, etc. suitably.

  In the flying pest repellent product of the present invention, it is preferable that the flying pest repellent fragrance composition to be held in the rubber molded body further contains a component that maintains the repellent effect when the flying pest repellent component is volatilized. The repellent effect sustained component is, for example, glycol and / or glycol ether having a vapor pressure at 20 ° C. of 0.2 to 20 Pa. Such glycols and / or glycol ethers are listed as solvents in the same line as ethanol, isopropanol, kerosene and the like in Patent Document 2, and Patent Document 3 describes that they exhibit excellent repellent effects on cockroaches and mites. However, it does not mention any effect on flying pests. However, the present inventors not only used the glycol and / or glycol ether as a solvent, but also had a repellent effect specific to the flying insect repellent, and used the aromatic flying insect repellent. In some cases, it has been found for the first time that the initial scent can be maintained.

  Specific examples of the glycols and / or glycol ethers (including vapor pressure at 20 ° C.) include propylene glycol (10.7 Pa), dipropylene glycol (1.3 Pa), tripropylene glycol (0.67 Pa), and diethylene glycol. (3 Pa), triethylene glycol (1 Pa), 1,3-butylene glycol, hexylene glycol (6.7 Pa), benzyl glycol (2.7 Pa), diethylene glycol monobutyl ether (3 Pa), dipropylene glycol monobutyl ether, and tri Examples include propylene glycol monomethyl ether, among which dipropylene glycol is suitable for the purpose of the present invention. In addition, said glycol and / or glycol ether may be used independently, and may be used in arbitrary combinations. The mixing ratio of glycol and / or glycol ether to the flying insect repellent is about 0.05 to 5 times.

  Other functional components may be blended in the flying insect repellent composition as long as the effects of the present invention are not hindered. Examples of other functional components include insecticidal components, deodorizing components, disinfecting / antibacterial components, and the like. Examples of the insecticidal component include room temperature volatile pyrethroids such as empentrin, profluthrin, transfluthrin, and metfurthrin. In the case of blending an insecticidal component, it is preferable to keep the amount as small as possible in light of the gist of the present invention. Representative examples of the deodorant component are plant extracts selected from the family Gramineae, Camellia, Ginkgoaceae, Arachnaceae, Mulberry, Citrus, Kintranoaceae, and Oysteraceae. In addition, green leaf alcohol or green leaf aldehyde called “green scent” can be added to give a relaxing effect. These functional components may be used alone or in any combination.

  As long as it does not hinder the effects of the present invention, the flying pest repellent fragrance composition may be optionally mixed with a solvent, a surfactant, a solubilizer, a dispersant, a stabilizer, a pH adjuster, or a colorant. Etc. may be appropriately blended. In addition, the flying pest repellent composition can be stabilized, for example, by microencapsulation or cyclodextrinization, or the volatility of the flying pest repellent composition can be adjusted. Is also possible.

  Examples of the solvent used for preparing the flying insect repellent product include water, lower alcohols such as ethanol and isopropanol, ketone solvents, ester solvents, and hydrocarbon solvents such as normal paraffin and isoparaffin. Examples of the surfactant include polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ethers (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene alkylphenyl ethers, polyoxyethylene higher fatty acid. Nonionic surfactants such as esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acid esters, polyoxyethylene polyoxypropylene alkyl ether, laurylamine oxide, stearylamine oxide, amidepropyldimethylamine laurate And higher alkylamine oxide surfactants such as oxide. These surfactants may be used alone or in any combination.

  By adding the above flying insect repellent fragrance composition to a rubber molded article containing silicone rubber and having a hardness of 50 degrees or less, by carrying out a predetermined treatment, the rubber molded article holds the flying pest repellent fragrance composition. The flying insect repellent product of the present invention is completed. And the flying insect repellent method of this invention can be implemented by using the flying insect repellent product of this invention.

  As a method for adding the flying insect repellent composition to a rubber molded body, a conventionally known method can be appropriately employed. For example, when the rubber molded body has a large surface area, the flying insect repellent composition is supported by a chemical liquid dispensing method or a coating method. If the surface area of the rubber molded body is small, put a large number of rubber molded bodies in a sealed container, add a flying insect repellent composition along with a solvent as necessary, and spray or drop to infiltrate the rubber molded body. . Further, the rubber molded body is immersed in the liquid of the flying insect repellent fragrance composition for an appropriate time, or the rubber molded body containing the flying insect repellent fragrance composition at a high concentration and an untreated rubber molded body are placed in a sealed container. It is also possible to produce a flying insect repellent product by a method in which the mixture is allowed to stand for an appropriate time and the concentration of the fragrance composition is averaged over the entire rubber molded body.

  What is necessary is just to determine suitably the compounding quantity of the flying insect repellent fragrance | flavor composition in the flying insect repellent product of this invention by the use use of the said flying insect repellent product, a use period, the kind of rubber molded object, its specification, etc. For example, in the case of a flying pest repellent product that is used for 8 to 12 hours per time, it is preferable to blend about 10 to 50 mg of a flying pest repellent fragrance composition per rubber molded body. In the case of a flying insect repellent product used for 15 to 30 days, it is preferable to blend about 100 to 2000 mg of a flying insect repellent fragrance composition per rubber molded body.

  In the flying insect repellent product of the present invention, the rubber molded product itself can be a flying insect repellent product. Examples of flying insect repellent products include wrist rings and wrist bands. In addition, the flying insect repellent product can be configured in a watch band shape, and in this case, a storage part for storing a small piece of a rubber molded body is formed in a part thereof, and the rubber molded body can be changed freely. Is possible. In this case, there is an advantage that the rubber molded body does not directly touch the skin of the arm.

  The flying pest repellent product of the present invention thus obtained can be used for interiors such as entrances, kitchens, toilets, living rooms, bedrooms, warehouses, cars, etc., gardens, outdoors, and other parts such as wrists and ankles. By attaching 1 to 5 as needed, mosquitoes such as mosquitoes, chikaeka, and mosquitoes, moths, chironomids, flies, flies (Drosophila, fleas, etc.), butterflies, squid It exhibits an excellent flying insect repellent effect over a predetermined period against flying insects such as mosquitoes. And when an aromatic flying pest repellent is used, the initial fragrance lasts for a predetermined period without deterioration, and since this product does not substantially contain an insecticidal component, Even people who do not like to use it can use it without resistance, so its practicality is extremely high.

  In order to confirm the effectiveness of the flying insect repellent product of the present invention, the following examples and comparative examples were carried out.

[Example 1]
As the acetate ester compound represented by the general formula (I) as the component (a) in the flying insect repellent fragrance component, p-tert-butylcyclohexyl acetate 8.0% by mass, and phenylethyl acetate 3.2% by mass, ( b) Monoterpene alcohol as component and / or aromatic alcohol having 10 carbon atoms, 14.3% by mass of terpineol, 9.8% by mass of geraniol, and 12.0% by mass of dihydromyrsenol, continuing repellent effect Ingredients include 38.0% by mass of dipropylene glycol and 14.7% by mass of other flying insect repellents (including 7.1% by mass of phenylethyl alcohol and 1.6% by mass of cinnamyl formate) A flying insect repellent fragrance composition of the present invention was prepared. The blending ratio of the component (a) to the component (b) in this flying insect repellent fragrance composition was 0.32 times.

  Next, a vulcanizing agent was added to the liquid silicone to form a string ring-shaped silicone rubber molded body (wire diameter: about 2 mm, weight: 1.6 g, hardness: 32). 100 rubber molded bodies were put in a sealed container provided with a spraying device, and the flying insect repellent fragrance composition was sprayed using the spraying device so that the amount of adsorption per rubber molded body was 30 mg. . The flying insect pest repellent composition was uniformly infiltrated into the entire rubber molded body after being left for 1 day to obtain a flying insect repellent product of the present invention having a wristband form and an effective duration of 8 to 12 hours. Separately, a silicone rubber molded body having a hardness of 80 degrees was tested in the same manner, but the flying insect repellent composition was only slightly adsorbed.

  When the obtained wristband was wound around the arm and went out, it was confirmed that a practical repellent effect was observed for 8 to 12 hours without being bothered by flying pests such as mosquitoes and fly flies. In addition, the scent of the original fragrance drifted in the surrounding space of the body, and I was able to enjoy a comfortable freshness.

In accordance with Example 1, as the acetate ester compound represented by the general formula (I) as the component (a) in the flying insect repellent component, 12 mg of styryl acetate, and the monoterpene alcohol as the component (b) and / or As an aromatic alcohol having 10 carbon atoms, 28 mg of geraniol was mixed, and each repellent effect sustaining ingredient was blended to prepare a flying pest repellent fragrance composition usable for the flying pest repellent product of the present invention. About the obtained flying pest repellent fragrance composition, the sustainability evaluation test 1 demonstrated below was implemented. In this test, the knockdown activity against the adult Culex pipiens (spider) was used as an index for sustainability evaluation.

A filter paper having a diameter of 15 cm was impregnated with 0.5 mL of an acetone solution of a reagent containing the above flying insect repellent and 70 mg of each repellent effect sustained ingredient, and then air-dried to prepare each reagent-treated filter paper. A plastic cylinder (inner diameter 20 cm, height 43 cm) was installed, and each reagent agent-treated filter paper was placed therein. A second cylinder (inner diameter: 20 cm, height: 20 cm) in which 20 adult mosquito mosquitoes were released was placed on the cylinder with a 12-mesh wire mesh, and a third cylinder (inner diameter: 20 cm, 43 cm in height) was placed. The number of test insects knocked down over time was counted, and a KT ₅₀ value (time until half of the test insects were knocked down) was determined. In addition, in order to evaluate the sustainability of each reagent reagent, the reagent-treated filter paper immediately after air drying (0h in Table 1) and the reagent-treated filter paper evaporated in a separate room for 4 hours after air drying ( Two types of 4h) in Table 1 were provided. The results of the sustainability evaluation test 1 are shown in Table 1.

  From the results in Table 1, it was confirmed that the glycol having a vapor pressure at 20 ° C. of 0.2 to 20 Pa and / or glycol ether had a sustained action of the knockdown effect, that is, the usefulness as a repellent effect sustained component. In addition, when the ethylene glycol type | system | group and the propylene glycol type | system | group were contrasted, the tendency for the latter to be preferable was observed. On the other hand, with regard to isopropyl myristate and neothiozole other than glycol and / or glycol ether, even when the vapor pressure at 20 ° C. is in the range of 0.2 to 20 Pa, the sustained action of the knockdown effect was poor.

  Based on the results of Table 1, the kind and blending amount of the flying insect repellent component were changed for hexylene glycol and dipropylene glycol, and the same sustainability evaluation test as described above was performed. The results are shown in Table 2.

  From the results shown in Table 2, the repellent effect sustained component used in the present invention is the acetate compound represented by the general formula (I) as the component (a) in the flying insect repellent component and the monoterpene as the component (b). More effective when the blending ratio of component (a) to component (b) is set to 0.1 to 2.0 times the amount in a combination with a system alcohol and / or an aromatic alcohol having 10 carbon atoms. It has been found that a sustained action of the knockdown effect is shown.

[Examples 2 to 10]
According to Example 1, a string ring-shaped silicone rubber molded body (wire diameter: about 2 mm, weight: 1.6 g, hardness: 30) was molded, and a flying insect repellent composition as shown in Table 3 was molded into this. 30 mg per body was added to obtain the flying insect repellent product of the present invention having an effective duration of about 8 to 12 hours.

Then added a vulcanizing agent to the liquid silicone, linked one string-like body simulating a character dragonfly with silicone rubber molding (wire diameter: 2 mm, length: 15cm, surface area: 9.42cm ^2, Hardness: 32) was molded. 100 pieces of this rubber molded body are put in a closed container provided with a spraying device, and the above-mentioned flying insect repellent composition is adsorbed to 30 mg (flight insect repellent flavoring ingredient) using the spraying device. As 19.1 mg). The flying insect pest repellent composition was uniformly infiltrated into the entire rubber molded body by allowing it to stand for 1 day to obtain the flying insect repellent product of the present invention in a wrist ring form and having an effective duration of about 10 hours. Separately, a silicone rubber molded body having a hardness of 80 degrees was tested in the same manner, but the flying insect repellent composition was only slightly adsorbed and could not be applied to the present invention.

The average volatilization amount of the flying pest repellent fragrance component per total surface area in this flying pest repellent product is 0.21 mg / cm ² · h, and when worn on the wrist, about 45% of the wrist ring is separated from the skin of the wrist. It was in a state.

  When two of the obtained wrist rings were wound around the wrists on the left and right, they went out for about 10 hours without being bothered by flying insects such as mosquitoes and fly flies, and a practical repellent effect was confirmed. In addition to being able to enjoy a sense of fun by wearing animal characters, the scent of the original fragrance drifted in the surrounding space of the body.

<Sustainability evaluation test 2>
According to Example 12, as the acetate ester compound represented by the general formula (I) which is the component (a) in the flying insect repellent component, 12 mg of styryl acetate is represented by the general formula (II) which is the component (a). As the allyl ester compound represented, 6 mg of allyl octanoate, (b) component monoterpene alcohol and / or aromatic alcohol having 10 carbon atoms, 25 mg of geraniol are mixed, and each repellent effect A flying pest repellent fragrance composition that can be used in the flying pest repellent product of the present invention was prepared by blending a continuous component. About the obtained flying pest repellent fragrance composition, the sustainability evaluation test 2 demonstrated below was implemented. In this test, the knockdown activity against the adult Culex pipiens (spider) was used as an index for sustainability evaluation.

A filter paper having a diameter of 15 cm was impregnated with 0.5 mL of an acetone solution of a reagent containing the above flying insect repellent and 70 mg of each repellent effect sustained ingredient, and then air-dried to prepare each reagent-treated filter paper. A plastic cylinder (inner diameter 20 cm, height 43 cm) was installed, and each reagent agent-treated filter paper was placed therein. A second cylinder (inner diameter: 20 cm, height: 20 cm) in which 20 adult mosquito mosquitoes were released was placed on the cylinder with a 12-mesh wire mesh, and a third cylinder (inner diameter: 20 cm, 43 cm in height) was placed. The number of test insects knocked down over time was counted, and a KT ₅₀ value (time until half of the test insects were knocked down) was determined. In order to evaluate the sustainability of each reagent reagent, the reagent-treated filter paper immediately after air drying (0h in Table 4) and the reagent-treated filter paper volatilized in a separate room for 4 hours after air drying ( Two types of 4h) in Table 4 were provided. The results of sustainability evaluation test 2 are shown in Table 4.

  From the results shown in Table 4, it was confirmed that the glycol having a vapor pressure at 20 ° C. of 0.2 to 20 Pa and / or glycol ether has a sustained action of the knockdown effect, that is, the usefulness as a repellent effect continuous component. In addition, when the ethylene glycol type | system | group and the propylene glycol type | system | group were contrasted, the tendency for the latter to be preferable was observed. On the other hand, with regard to isopropyl myristate and neothiozole other than glycol and / or glycol ether, even when the vapor pressure at 20 ° C. is in the range of 0.2 to 20 Pa, the sustained action of the knockdown effect was poor.

  Based on the results in Table 4, the kind and blending amount of the flying insect repellent were changed for hexylene glycol and dipropylene glycol, and the same sustainability evaluation test as described above was performed. The results are shown in Table 5.

  From the results of Table 5, the repellent effect sustaining component used in the present invention is the acetate compound represented by the general formula (I) as the component (a) in the flying insect repellent component and the monoterpene as the component (b) More effective when the blending ratio of component (a) to component (b) is set to 0.1 to 2.0 times the amount in a combination with a system alcohol and / or an aromatic alcohol having 10 carbon atoms. It has been found that a sustained action of the knockdown effect is shown.

[Examples 13 to 22]
According to Example 12, a silicone rubber molded body (wire diameter: 2 mm, length: 10 to 20 cm, hardness: 30) imitating an animal character with a string-like body, the flying insect repellent fragrance composition described in Table 6 In order to contain 25 mg per molded body, a total amount of 1500 mg (25 mg × 6 × 10) of flying pest repellents corresponding to 10 times the amount of each flying pest repellent composition per untreated molded body The composition was added to produce a concentrated liquid-containing molded body. Next, 54 untreated silicone rubber moldings were put together with the six concentrated liquid-containing moldings in an aluminum bag whose inner surface was coated with a polyester film, sealed, and left for 7 to 10 days. The flying pest repellent composition is uniform throughout the bag, the content of the flying pest repellent composition per piece is 25 mg, and the effective duration is about 8 to 12 hours. A pest repellent product (character name is written in the lower part of the specimen number) was obtained. Two open plastic cups (approx. 1 L) without a lid were provided in the test chamber (approx. 6 m ³ ). A Drosophila attracting source and a test flying insect repellent product were placed in one plastic cup (treatment zone), and only a Drosophila attracting source was placed in the other plastic cup (control zone). Five hours after use, adult Drosophila (about 100 animals) were released into the room, and the number of invading insects in the plastic cups was counted, and the repelling rate was calculated according to the following formula.
Repelling rate = [(number of invasive insects in control group−number of invasive insects in treatment group) / number of invasive insects in control group] × 100

From the results shown in Table 6, the flying pest repellent product of the present invention (a flying pest repellent composition containing a flying pest repellent component, and preferably further combined with a repellent effect sustaining component), a silicone rubber molded article having a hardness of 50 degrees or less. The average volatilization amount of the flying insect repellent fragrance component per total surface area of the silicone rubber molded body when the part is expanded and attached to a part of the human body such as the wrist or ankle is 0.05 to 1.0 mg / cm ² · h) was found to exhibit an excellent flying insect repellent effect in a test 5 hours after volatilization. Moreover, the acetic ester compound represented by the general formula (I) which is the component (a) in the flying insect repellent fragrance component, and / or the allyl ester compound represented by the general formula (II) which is the component (a), In combination with (b) component monoterpene alcohol and / or C10 aromatic alcohol, combination ratio of component (a) to component (b) is combined in an amount of 0.1 to 2.0 times. In this case, the action of the repellent effect sustaining component was expressed more efficiently, and not only the repellent rate but also the sustainability of the fragrance was obtained.

  Furthermore, when a part of the silicone rubber molded body is expanded and attached to a part of a human body such as a wrist or ankle, the contact area between the rubber molded body and a part of the human body is smaller than the area of the inner surface of the rubber molded body. 80% or less, preferably 70% or less, so that at least 20%, preferably 30%, of the rubber molded body is in a wearing state separated from the skin of the wrist or ankle, and the volatility is improved and stabilized. It was favorable in terms of conversion.

In addition, as in Example 21, when the average volatilization amount is less than 0.05 mg / cm ² · h, the repelling effect is low, whereas as in Example 22, the average volatilization amount is 1.0 mg / cm ^2.・ When h is exceeded, there is a tendency for the persistence of the repellent effect to be shortened. Accordingly, it was confirmed that the vapor pressure at 20 ° C. of the glycol and / or glycol ether-based repellent effect sustained component is preferably in the range of 0.2 to 20 Pa.

  On the other hand, Comparative Example 3 using a silicone rubber molded body having a hardness exceeding 50 degrees had poor repellent effect. In addition, in the case of Comparative Example 4 using mint oil, which is difficult to say as a flying insect repellent, a sufficient repellent effect was not obtained.

  Therefore, it is clear that the practical application of the flying insect repellent product of the present invention in which the silicone rubber molding is combined with a flying insect repellent fragrance component, and preferably a repellent effect sustaining component.

  The flying insect repellent product and the flying insect repellent method of the present invention can be used not only for flying insects but also for the purpose of controlling a wide variety of insects.
