Description

本発明は、蚊、蚋、ユスリカ忌避剤に関するものである。 The present invention relates to a mosquito, moth, chironomid repellent.

従来、蚊、蚋、ユスリカなどの飛翔害虫に対して、ディート(N,N−ジエチル−トルアミド)を含む忌避剤を皮膚表面に塗布する方法が汎用されてきたが、ディートは通常の香料成分と比べると揮散性が幾分低いために空間的な忌避効果は期待できない。
そこで、忌避成分として揮散性の天然精油やその組成成分を利用しようとする提案がいくつかある。例えば、シトロネラ油やその主成分であるシトロネラールが蚊に対して忌避効果を示すことはよく知られており、アメリカではシトロネラ油を有効成分として含有するキャンドルが市販された。しかしながら、キャンドルの熱を利用してシトロネラールを放散させる方法はシトロネラールの揮散効率が悪く、実用的な忌避効果を奏しえない。
また、特開2002−173407号公報には、シトロネラ油の外、オレンジ油、カシア油などから選ばれた天然精油を有効成分とする飛翔害虫忌避剤が記載され、更に、特開2003−201203号公報には、害虫忌避成分(A)として、シトロネラールと、ターピネオール、メントール、リモネン、ゲラニオール、シトロネロール、カンフェン等から選ばれる1種又は2種以上とを含み、害虫忌避成分(A)中におけるシトロネラールの含有量が2〜10質量%である害虫忌避剤揮散組成物が開示されている。これらの忌避剤は、天然産志向と安全性への配慮を謳っているものの、その忌避効果は必ずしも満足のいくものではない。
特開2002−173407号公報 特開2003−201203号公報
Conventionally, a method of applying a repellent containing diet (N, N-diethyl-toluamide) to the skin surface against flying pests such as mosquitoes, moths and chironomids has been widely used. In comparison, the volatility is somewhat low, so a spatial repellent effect cannot be expected.
Therefore, there are some proposals 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 describes a flying insect repellent containing as an active ingredient a natural essential oil selected from orange oil, cassia oil and the like in addition to citronella oil, and further, Japanese Patent Application Laid-Open No. 2003-201203. The gazette includes citronellal as a pest repellent component (A) and one or more selected from terpineol, menthol, limonene, geraniol, citronellol, camphene, etc., and citronellal in pest repellent component (A) A pest repellent volatilization composition having a content of 2 to 10% by mass is disclosed. Although these repellents urge the attention to natural products and safety, their repellent effects are not always satisfactory.

本発明の蚊、蚋、ユスリカ忌避剤は、忌避成分として有用なアリルエステル化合物を含有し、蚊、蚋、ユスリカに対してシトロネラールに勝る忌避効果を示すので、その実用性は極めて高い。 The mosquito, spider and chironomid repellent of the present invention contains an allyl ester compound useful as a repellent component, and exhibits a repellent effect superior to citronellal against mosquitoes, spiders and chironomids , so that its practicality is extremely high.

本発明で用いる炭素数が4〜8の脂肪酸のアリルエステル化合物は、香料成分として公知であるが、忌避効果についてはほとんど知られていない。しかるに、本発明者らは繰り返し試験を行い、その結果に基づきアリルエステル化合物の高い蚊、蚋、ユスリカに対する忌避効果を新たに知見したものである。
当該アリルエステル化合物としては、アリルブタノエート、アリルペンテノエート、アリルヘキサノエート、アリルヘプタノエート、アリルオクタノエートがあげられ、なかんずくアリルヘキサノエート及び/又はアリルヘプタノエートは忌避効果が高く、かつ入手しやすいので好適である。
これらの化合物は、蚊、蚋、ユスリカに対し常温揮散性のピレスロイド系殺虫成分のような速効的なノックダウン効果を示さないものの、人畜に対して比較的安全性が高く同時に芳香感も奏しえるというメリットがある。
The allyl ester compounds of fatty acids having 4 to 8 carbon atoms used in the present invention are known as perfume ingredients, but little is known about the repellent effect. However, the present inventors conducted repeated tests, and based on the results, newly found repellent effects on mosquitoes, moths and chironomids with high allyl ester compounds.
Examples of the allyl ester compounds include allyl butanoate, allyl pentenoate, allyl hexanoate, allyl heptanoate, and allyl octanoate, and allyl hexanoate and / or allyl heptanoate are repellent effects. Is suitable because it is high and easily available.
Although these compounds do not show a quick knockdown effect like chilled pyrethroid insecticides against mosquitoes, moths and chironomids, they are relatively safe for human animals and can also provide a sense of fragrance. There is a merit.

上記アリルエステル化合物には更に避成分として、他の天然精油や天然もしくは合成香料、例えばシトロネラール、シトロネロール、シトラール、リナロール、テルピネオール、メントール、メンタン、p−メンタン−3,8−ジオール、カンフェン、メチルサリシレート、ピネン、リモネン、ゲラニオール、ボルネオール、ゲラニルフォーメート、シトロネラ油、シナモン油、ユーカリ油、レモンユーカリ油、ヒバ油、ラベンダー油、オレンジ油、グレープフルーツ油、シダーウッド油、ゼラニウム油、タイムホワイト油、ハッカ油などから選ばれた1種又は2種以上を配合してもよい。これらの中では、シトロネラール、シトロネロール、シトラール、リナロール、テルピネオール、メントール、メンタン、p−メンタン−3,8−ジオール、カンフェン、メチルサリシレート、シトロネラ油、シナモン油、ユーカリ油、レモンユーカリ油、ヒバ油が忌避効果の点で好ましい。 As a further memorial避成content in the allyl ester compound, other natural essential oils and natural or synthetic perfumes, for example, citronellal, citronellol, citral, linalool, terpineol, menthol, menthane, p- menthane-3,8-diol, camphene, methyl Salicylate, pinene, limonene, geraniol, borneol, geranyl formate, citronella oil, cinnamon oil, eucalyptus oil, lemon eucalyptus oil, hiba oil, lavender oil, orange oil, grapefruit oil, cedarwood oil, geranium oil, thyme white oil, mint You may mix | blend 1 type (s) or 2 or more types chosen from oil etc. Among these, citronellal, citronellol, citral, linalool, terpineol, menthol, menthane, p-menthane-3,8-diol, camphene, methyl salicylate, citronella oil, cinnamon oil, eucalyptus oil, lemon eucalyptus oil, hiba oil It is preferable in terms of repellent effect.

本発明の蚊、蚋、ユスリカ忌避剤は、上記アリルエステル化合物を含む避成分のみで構成しても構わないが、通常各種の成分を加えて種々の形態に調製される。そして、避成分の忌避剤全体量に対する比率は、忌避剤の形態によっても異なるが、例えば液状のような場合、0.5〜5.0重量%程度に設定するのが好ましい。0.5重量%未満であると忌避効果が十分でなく、一方5.0重量%を超えると匂いが強くなりすぎるので実用的でない。また、ゲル状体にあっては、避成分の配合量は、0.5〜10重量%程度が適当である。 Mosquitoes present invention, gnat, midge repellent, but may be constituted of only the memorial避成content including the allyl ester compound, are formulated into various forms by adding a conventional various components. The ratio repellent total amount of memorial避成content varies also depending on the form of the repellent, for example, in the case such as a liquid, preferably set to about 0.5 to 5.0 wt%. If the amount is less than 0.5% by weight, the repellent effect is not sufficient. On the other hand, if it exceeds 5.0% by weight, the odor becomes too strong, which is not practical. Moreover, in the gel-like body, the amount of the memorial避成content is about 0.5 to 10 wt% is appropriate.

本発明の蚊、蚋、ユスリカ忌避剤は、忌避効果と人畜に対する安全性に支障を来たさない限りにおいて、緑茶抽出物や柿抽出物のような植物由来の消臭成分や、香調の調整のために他の芳香成分を配合してもよい。また、常温揮散性のピレスロイド系殺虫成分、例えば、エムペントリン、2,3,5,6−テトラフルオロベンジル−2,2−ジメチル−3−(2,2−ジクロロビニル)シクロプロパンカルボキシレート[トランスフルトリン]、4−メチル−2,3,5,6−テトラフルオロベンジル−2,2−ジメチル−3−(1−プロペニル)シクロプロパンカルボキシレート、4−メトキシメチル−2,3,5,6−テトラフルオロベンジル−2,2−ジメチル−3−(1−プロペニル)シクロプロパンカルボキシレートなどを添加して忌避効果を増強させることもできる。 The mosquito, moth, chironomid repellent of the present invention has a deodorant component derived from plants such as green tea extract and cocoon extract, as long as it does not interfere with the repellent effect and safety for human livestock. You may mix | blend another aromatic component for adjustment. Also, room temperature volatile pyrethroid insecticides such as empentrin, 2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (2,2-dichlorovinyl) cyclopropanecarboxylate [Transflux Thrin], 4-methyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate, 4-methoxymethyl-2,3,5,6- Tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate can be added to enhance the repellent effect.

なお、安定化剤、pH調整剤、着色剤などを適宜配合してもよいことはもちろんである。
The mosquito, moth and chironomid repellent of the present invention can adopt various forms such as liquid, gel, solid and sheet according to the needs of the usage scene.
In preparing the liquid agent, in addition to water, lower alcohols such as ethanol and isopropanol, glycols such as propylene glycol, glycol ether water-soluble organic solvents such as diethylene glycol monobutyl ether and dipropylene glycol monomethyl ether, aliphatic or Aromatic hydrocarbon solvents, surfactants, solubilizers, and dispersants are appropriately used.
Examples of the gelling agent used for preparing the gel-like body include carrageenan, xanthan gum, gellan gum, gelatin, aluminum octylate, and 12-hydroxystearic acid.
On the other hand, pulp, linter, cellulosic carriers such as rayon, silicates, silica, inorganic porous carrier such as zeolite, trioxane, the sublimable carrier adamantane, impregnated with a solvent or the like if necessary memorial避成min Solid, sheet, and granular mosquito, moth, and chironomid repellents can be prepared.
Of course, stabilizers, pH adjusters, colorants, and the like may be added as appropriate.

次に、液状形態の蚊、蚋、ユスリカ忌避剤について詳述する。
処方としては、避成分を0.5〜5.0重量%、界面活性剤を3.0〜12重量%、低級アルコールを2.0〜10重量%及び水を含有してなる水性液剤が好ましく、この忌避剤は、吸液芯を介して吸液素材の蒸発部に導き避成分を空間に放散させる方式や、スプレー方式、あるいは噴射剤を伴ってエアゾール方式に好適に適用される。
Next, liquid form mosquitoes, moths, chironomid repellents will be described in detail.
The formulation, a memorial避成content 0.5 to 5.0 wt%, the surfactant 3.0 to 12% by weight, aqueous solutions comprising the 2.0 to 10 wt% and water lower alcohol preferably, the repellent is, method and dissipating避成component mourning leads to the evaporation of the liquid absorbing material through the wick into space, is preferably applied in a spray method or an aerosol method with a propellant.

界面活性剤は、避成分の安定性と放散性の点から、高級アルキルアミンオキサイド系界面活性剤と非イオン系界面活性剤が併用されるのが好ましい。
高級アルキルアミンオキサイド系界面活性剤としては、例えばラウリルアミンオキサイド、ステアリルアミンオキサイド、ラウリル酸アミドプロピルジメチルアミンオキサイドなどがあげられ、一方、非イオン系界面活性剤としては、ポリオキシエチレン硬化ヒマシ油、ポリオキシエチレン高級アルキルエーテル(ポリオキシエチレンラウリルエーテル、ポリオキシエチレンオレイルエーテル)、ポリオキシエチレン高級脂肪酸エステル、ポリオキシエチレンポリオキシプロピレンアルキルエーテルなどを例示できる。
界面活性剤が3.0重量%未満であると避成分の可溶化が劣り、12重量%を越えると避成分の放散性に影響を及ぼす恐れがある。
Surfactant, from the viewpoint of emission stability and the memorial避成min, preferably higher alkyl amine oxide surfactant and the nonionic surfactant are used in combination.
Examples of higher alkylamine oxide surfactants include laurylamine oxide, stearylamine oxide, lauric acid amidopropyldimethylamine oxide, and the like, while nonionic surfactants include polyoxyethylene hydrogenated castor oil, Examples include polyoxyethylene higher alkyl ether (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether), polyoxyethylene higher fatty acid ester, polyoxyethylene polyoxypropylene alkyl ether, and the like.
Poor solubilization of memorial避成min and the surfactant is less than 3.0 wt%, it may affect more than the memorial避成amount of dissipation of 12 wt%.

低級アルコールとしては、エタノール又はイソプロパノールが代表的で、エタノールが性能的に好ましい。低級アルコールの配合量が2.0重量%未満の場合、高級アルキルアミンオキサイド系界面活性剤との相溶性が劣り、一方10重量%を超えると火気に対する危険性が増大し、消防法上の非危険物に該当しない場合が生ずる。 As the lower alcohol, ethanol or isopropanol is representative, and ethanol is preferable in terms of performance. When the blending amount of the lower alcohol is less than 2.0% by weight, the compatibility with the higher alkylamine oxide surfactant is inferior. On the other hand, when it exceeds 10% by weight, the danger to fire is increased. There are cases where it does not fall under dangerous goods.

こうして得られた蚊、蚋、ユスリカ忌避剤は、例えば吸液芯を有する容器本体に充填され、吸液芯を介して避成分を空間に放散させる方式に適用される。
ここで、容器本体は、その材質や構造に特に制限はなく、例えばプラスチック、ガラス、陶器製などがあげられる。内部の液量を視認できる透明ないし半透明のプラスチックあるいはガラス容器が好ましく、表面をダイアカットやボヘミアンカット状に加工してもよい。通常、容器本体の容量としては50ないし300mL程度のものが実用的である。そして、容器本体の底部は、液剤が残りなく吸い上げられるように、後記する吸液芯の当接部を幾分凹状に構成するのがよい。
この容器本体上部の開口部には吸液芯を保持する中栓が冠着される。中栓はプラスチック製が好ましく、また、開口部冠着位置から下方に向けて筒状に形成し吸液芯を挿入するようにすれば、吸液芯を確実に保持できるのでより好適である。
Thus obtained mosquitoes, gnat, midge repellents, for example, is filled in a container body having a liquid absorbing core, it is applied to a method of dissipating the space memorial避成content via a wick.
Here, the material and structure of the container body are not particularly limited, and examples thereof include plastic, glass, and ceramics. A transparent or translucent plastic or glass container in which the amount of liquid inside can be visually confirmed is preferable, and the surface may be processed into a diacut or bohemian cut. Usually, a container body with a capacity of about 50 to 300 mL is practical. And the bottom part of a container main body should comprise the contact part of the liquid absorption core mentioned later somewhat concavely so that a liquid agent may be sucked up without remaining.
An inner plug for holding the liquid absorbent core is attached to the opening at the top of the container body. The inner plug is preferably made of plastic, and if it is formed in a cylindrical shape downward from the crowning position of the opening and the liquid absorbent core is inserted, it is more preferable because the liquid absorbent core can be securely held.

吸液芯は、忌避剤に対して安定でかつ毛細管現象で水溶液を吸液するものであり、具体的な材質として例えばナイロン、ポリエステルなどのプラスチック繊維、天然繊維、木材などがあげられる。このうちプラスチック繊維又は天然繊維製フェルト吸液芯が使いやすく、外径3〜10mm程度の棒状もしくは撚芯状に形成して使用に供される。 The liquid absorbent core is stable against repellents and absorbs an aqueous solution by capillary action. Specific examples of materials include plastic fibers such as nylon and polyester, natural fibers, and wood. Of these, a felt absorbent core made of plastic fiber or natural fiber is easy to use, and is formed into a rod shape or a twisted core shape having an outer diameter of about 3 to 10 mm and is used.

通常、吸い上げた忌避剤を放散させる蒸発部が吸液芯の上部に設けられる。蒸発部の構造はフェルトもしくはシート状であり、またその材質としては吸液芯の場合と同様、例えばナイロン、ポリエステルなどのプラスチック繊維、天然繊維、木材などを使用できる。このうちプラスチック繊維又は天然繊維製のフェルトもしくはシート状のものが好ましく、厚み2〜15mmで、表面積が10〜60cm2の略円形に成型し、これを吸液芯の頂面に当接するように配設すれば、吸い上げられた忌避剤は吸液芯から蒸発部に移行し、ここから徐々に空中に放散する。蒸発部の表面積が10cm2未満であると蒸発量が低くなる傾向があるし、一方60cm2を超えると蒸発量過多となって持続性に問題を生じる場合がある。通常、忌避剤の1日あたりの空中への蒸発量を1〜8mLとし、有効持続時間は1〜2ケ月に調整される。
また、蒸発部支持体を付設したり、蒸発部に指などが触れないように蒸発部をカバーするメッシュ状の蓋部材を備えるのが一般的である。
更に、インテリア性を付与するために、蒸発部支持体を介して布又はプラスチック製の造花を装填してもよい。造花は、アジサイ、スズラン、バラ、除虫菊、アイビーなど、各種の草花を模して作製され、見かけの体積は200〜1500cm3程度がよい。
Usually, an evaporating part for dissipating the sucked repellent is provided at the upper part of the liquid absorbent core. The structure of the evaporating part is felt or sheet-like, and the material thereof can be, for example, plastic fibers such as nylon and polyester, natural fibers, wood, etc., as in the case of the liquid absorbent core. Of these, a plastic fiber or natural fiber felt or sheet-like material is preferable, and it is formed into a substantially circular shape having a thickness of 2 to 15 mm and a surface area of 10 to 60 cm 2 , and this is in contact with the top surface of the liquid absorbent core. If arranged, the sucked repellent moves from the liquid absorption core to the evaporation section and gradually diffuses into the air from here. If the surface area of the evaporating part is less than 10 cm 2 , the amount of evaporation tends to be low, while if it exceeds 60 cm 2 , the amount of evaporation is excessive, which may cause a problem in sustainability. Usually, the daily evaporation amount of the repellent is set to 1 to 8 mL, and the effective duration is adjusted to 1 to 2 months.
Moreover, it is common to provide the evaporation part support body, or to provide a mesh-like lid member that covers the evaporation part so that a finger or the like does not touch the evaporation part.
Furthermore, in order to provide interior characteristics, cloth or plastic artificial flowers may be loaded through the evaporation unit support. Artificial flowers are made by imitating various kinds of flowers such as hydrangea, lily of the valley, roses, pesticides, and ivy, and the apparent volume is preferably about 200 to 1500 cm 3 .

蚊、蚋、ユスリカ忌避剤がゲル状体や固形状、シート状等の場合も常法に従って調製することができ、使用目的や使用場面に適した製剤(ファン式虫よけ器具、防虫カーテン等)に適用して避成分を効率よく空間に放散させることができる。
このように、本発明の蚊、蚋、ユスリカ忌避剤は、リビングや和室、玄関などの室内、倉庫、飲食店、キャンプなどで、アカイエカ、チカイエカ、ヒトスジシマカなどの蚊類、蚋、ユスリカ類対して実用的な忌避効果を奏するものである。そして、本発明の蚊、蚋、ユスリカ忌避剤によれば、1ケ月ないし2ケ月間の長期間にわたり、実用的な忌避効果と同時に芳香感を満喫することができ、更に、造花を装填してリビングや玄関に設置すれば、インテリア性が付与され花の観賞をも楽しめるのでその実用性は極めて高い。
When mosquitoes, moths, chironomid repellents are gel-like, solid, or sheet-like, they can be prepared according to conventional methods, and formulations suitable for the purpose and use (fan-type insect repellent devices, insect curtains, etc.) can be dissipated memorial避成content efficiently space applied to).
Thus, mosquito present invention, gnat, midge repellents and living Japanese style room, such as the entrance, warehouses, restaurants, camping, etc., against Culex, Culex pipiens, mosquitoes such as Aedes albopictus, gnat, a midge acids And has a practical repellent effect. According to the mosquito, moth and chironomid repellent of the present invention, it is possible to fully enjoy the fragrance simultaneously with the practical repellent effect over a long period of one to two months, and further, it is loaded with artificial flowers. If it is installed in the living room or the entrance, it is very practical because it gives interior and you can enjoy the flowers.

A disc-like felt evaporation part 6 having a thickness of 5 mm and a diameter of 5.2 cm, which is installed on the evaporation part support 5, was attached to the top surface of the liquid absorbent core 3. Further, a plastic artificial flower 7 having an apparent volume of 350 cm 3 and imitating an ivy was loaded through the evaporation unit support 5 above, to prepare a stationary insect repellent device.
When this insect repellent device was placed on the side board of the entrance, it was possible to enjoy the fragrance for about 2 months and not be bothered by mosquitoes. In addition, Ivy's green matched the entrance and was excellent in interior.

アリルヘキサノエート1.5g、ユーカリ油0.8gと4−メチル−2,3,5,6−テトラフルオロベンジル−2,2−ジメチル−3−(1−プロペニル)シクロプロパンカルボキシレート0.1gに、ゲル化剤(オクチル酸アルミニウム)2.0g、ジエチレングリコールブチルエーテル1.0g、及びイソパラフィン系炭化水素114.6gを加え、ゲル状の蚊、蚋、ユスリカ忌避剤120gを調製した。
これをポリエステル容器本体に充填し、40%の有孔面積を有する蓋部材を容器本体の上部開口部に取り付けて、ゲル状タイプの虫よけ器具を作製した。
この虫よけ器具は、実施例1と同様、蚊や蚋対して優れた忌避効果を示した。
1.5 g of allyl hexanoate, 0.8 g of eucalyptus oil and 0.1 g of 4-methyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate To this, 2.0 g of a gelling agent (aluminum octylate), 1.0 g of diethylene glycol butyl ether, and 114.6 g of isoparaffinic hydrocarbon were added to prepare 120 g of a gel-like mosquito, moth and chironomid repellent.
This was filled into a polyester container body, and a lid member having a 40% perforated area was attached to the upper opening of the container body to produce a gel-type insect repellent device.
The insect repellent device is similar to that in Example 1, showed excellent repellent effect against the mosquitoes and gnat.

実施例1に準じて、表1に示す各種蚊、蚋、ユスリカ忌避剤を調製し、吸液芯を収容した虫よけ器具に適用して下記の忌避効力試験を実施した。
[忌避効力試験]
密閉した6畳の部屋の中央に、金網で固定したマウス(吸血源)と供試虫よけ器具を設置し、アカイエカ雌成虫50匹を放ち、2時間後に供試虫を回収して吸血虫数を数え、吸血率を求めた(処理区)。同時に同じ広さの部屋で虫よけ器具を設置せずに同様の試験を行い(コントロール区)、その吸血率から次式に従って忌避率(吸血阻止率)を算出した。
忌避率(%)=[コントロール区の吸血率−処理区の吸血率]/コントロール区の吸血率
×100
In accordance with Example 1, various mosquito, moth and chironomid repellents shown in Table 1 were prepared and applied to an insect repellent device containing a liquid absorbent core, and the following repellent efficacy test was performed.
[Repellent efficacy test]
In the center of a sealed 6 tatami room, a mouse (blood-sucking source) fixed with a wire mesh and a test insect repellent device are installed, 50 adult female squids are released, and after 2 hours, the test insects are collected and the blood-sucking insect The number was counted to determine the blood absorption rate (treatment section). At the same time, a similar test was performed in a room of the same size without installing an insect repellent device (control zone), and the repelling rate (blood absorption inhibition rate) was calculated from the blood absorption rate according to the following formula.
Repelling rate (%) = [blood absorption rate of control group−blood absorption rate of treatment group] / blood absorption rate of control group × 100

試験の結果、本発明の蚊、蚋、ユスリカ忌避剤は、忌避成分として配合したアリルエステル化合物の作用に基づき、アカイエカに対してシトロネラールに勝る忌避効果を示し、またいずれも火気に対する危険性が低く使用性の面でも優れたものであった。
これに対し、比較例1ないし比較例4に示すように、シトロネラール、p−メンタン−3,8−ジオール、テルピネオール、リナロールの忌避効果は、アリルエステル化合物に比べて劣ることが認められた。また、アリルエステル化合物のなかでも、脂肪酸の炭素数が4〜8の範囲から外れるアリルアセテート(比較例5)は、忌避効果が低かった。
The results of the tests, mosquitoes present invention, gnat, midge repellants, based on the action of the allyl ester compound formulated as repellent component, shows the repellent effect over citronellal against Culex, also both low risk for fire It was also excellent in terms of usability.
On the other hand, as shown in Comparative Examples 1 to 4, it was recognized that the repellent effect of citronellal, p-menthane-3,8-diol, terpineol, and linalool was inferior to that of the allyl ester compound. Moreover, among allyl ester compounds, allyl acetate (Comparative Example 5) in which the number of carbon atoms of the fatty acid is out of the range of 4 to 8 has a low repellent effect.
