有鱗目動物忌避剤Squamata repellent
　本発明は有鱗目動物忌避剤に関し、さらに詳しくは、エアゾール剤の形態で使用される有鱗目動物忌避剤に関する。 The present invention relates to a reptile repellent, and more particularly to a reptile repellent used in the form of an aerosol.
　ヤモリは昆虫や蜘蛛、蚊等の小さな害虫を捕食するため益虫とされているが、屋内への侵入や糞被害が問題となっている。ヤモリは気温が３０℃前後の地域に多く生息し、南極大陸を除く全大陸に分布しており、日本においても本州、四国、九州、周辺島嶼に生息していることが確認されている。ヤモリは夜行性であり、夜に街灯や民家の光に集まっている虫を狙って現れるので、壁や窓に張り付いているところを発見することができる。 The gecko is considered to be a beneficial insect because it preys on small pests such as insects, spiders, and mosquitoes, but invasion into the room and damage to feces are problems. Many geckos inhabit areas with temperatures around 30 ° C, and are distributed on all continents except Antarctica. It has been confirmed that geckos also inhabit Honshu, Shikoku, Kyushu, and surrounding islands in Japan. Geckos are nocturnal and appear at night when they aim at insects gathering in the light of street lights and private houses, so you can find them sticking to walls and windows.
　従来、ヤモリに対しては忌避により追い払うことが行われており、例えば、ヤモリやそれに類する動物の嫌がる臭いを発散させる忌避剤を撒くことがなされる。このような忌避剤として、例えば、特定一般式で表されるグリコールエーテル類を有効成分とする爬虫類用忌避剤（特許文献１）や、リモネンを主体とする動物忌避・消臭剤（特許文献２）が提案されている。特許文献１には前記特定一般式で表されるグリコールエーテル類がヘビやトカゲ等の爬虫類に対して忌避効力を有することが記載され、特許文献２にはリモネンがヘビやヤモリに忌避作用を示すことが記載されている。 Conventionally, geckos have been repelled by repellent, for example, a repellent that emits the odor that geckos and similar animals dislike is sprinkled. Examples of such a repellent include a reptile repellent containing glycol ethers represented by a specific general formula as an active ingredient (Patent Document 1) and an animal repellent / deodorant mainly containing limonene (Patent Document 2). ) Has been proposed. Patent Document 1 describes that glycol ethers represented by the specific general formula have a repellent effect on reptiles such as snakes and lizards, and Patent Document 2 shows limonene has a repellent effect on snakes and geckos. It is stated that.

　しかしながら、特許文献１、２のような忌避剤を用いると、散布直後の忌避効果は得られるが、経時的に臭いが薄まるため、効果の持続性が低いという問題があった。
　また、ヤモリやトカゲ等の有鱗目動物は壁や窓などの高所や垂直面にも張り付くことから、そのような場所に対して、有効成分を簡便に処理することが難しいという問題があった。
　本発明は、有鱗目動物に対して優れた忌避効果を持続的に発揮し、使用初期から使用終期にかけて効果のバラつきなく、簡便に使用することができる有鱗目動物忌避剤を提供することを課題とする。 However, when a repellent as in Patent Documents 1 and 2 is used, a repellent effect immediately after spraying can be obtained, but there is a problem that the effect is not sustained because the odor diminishes with time.
In addition, since scaled reptiles such as geckos and lizards stick to high places such as walls and windows and vertical surfaces, there is a problem that it is difficult to easily process the active ingredient in such places. It was.
The present invention provides a scaled reptile repellent that continuously exerts an excellent repellent effect on scaled reptiles and can be easily used without variation in the effect from the initial stage of use to the final stage of use. Is the subject.
　本発明者らは上記課題について鋭意研究を重ねた結果、無機粉体を有効成分としたエアゾール剤であって、前記無機粉体と共に、ヒドロキシ基又はケトン基を有する溶剤及びシリコーン粉体のうちの少なくとも一方を含有させることにより上記課題を解決できることを見出し、本発明を完成するに至った。 As a result of diligent research on the above-mentioned problems, the present inventors have made an aerosol agent containing an inorganic powder as an active ingredient, and among the above-mentioned inorganic powder, a solvent having a hydroxy group or a ketone group, and a silicone powder. We have found that the above problems can be solved by containing at least one of them, and have completed the present invention.
　すなわち本発明は、以下の（１）～（３）を特徴とする。
（１）原液と噴射剤からなるエアゾール組成物が耐圧容器に充填されてなるエアゾール剤の形態を有し、前記原液が、有効成分として無機粉体と、ヒドロキシ基又はケトン基を有する溶剤及びシリコーン粉体のうちの少なくとも一方を含有する有鱗目動物忌避剤。

　本発明の有鱗目動物忌避剤によれば、エアゾール剤の形態を有するので処理したい場所に簡便に処理することができる。また、有鱗目動物に対して忌避効果を発揮する無機粉体の、エアゾール組成物中における分散性に優れ、またケーキングも抑制されるので、忌避剤の使用初期から使用終期まで一定した噴射をすることができ、有鱗目動物に対して優れた忌避効果を持続的に得ることができる。 According to the scaled reptile repellent of the present invention, since it has the form of an aerosol agent, it can be easily treated at a place to be treated. In addition, the inorganic powder, which exerts a repellent effect on scaled reptiles, has excellent dispersibility in the aerosol composition and suppresses caking, so that the repellent can be sprayed constantly from the beginning to the end of use. It is possible to continuously obtain an excellent repellent effect on scaled reptiles.
　以下、本発明の有鱗目動物忌避剤について説明する。
　なお、本明細書において、「質量」は「重量」と同義である。 Hereinafter, the scaled reptile animal repellent of the present invention will be described.
In addition, in this specification, "mass" is synonymous with "weight".
　本発明で忌避の対象とする有鱗目動物は爬虫類に属する群であり、トカゲ類やヘビ類を含む。具体的には、ヤモリ、トカゲ、カナヘビ、イグアナ、カメレオン等のトカゲ亜目、アオダイショウ、マムシ等のヘビ亜目、ミミズトカゲ等のミミズトカゲ亜目等を含む。 The scaled reptiles to be repelled in the present invention are a group belonging to reptiles, including lizards and snakes. Specifically, it includes lizard suborders such as geckos, lizards, cana snakes, iguanas and chameleons, snake suborders such as blue-green algae and beetles, and Amphisbaenia suborders such as Amphisbaenia.
　本発明の有鱗目動物忌避剤は、原液と噴射剤からなるエアゾール組成物が耐圧容器に充填されてなるエアゾール剤の形態を有し、前記原液が、有効成分として無機粉体と、ヒドロキシ基又はケトン基を有する溶剤及びシリコーン粉体のうちの少なくとも一方を含有する。以下、各成分について説明する。 The scaled animal repellent of the present invention has the form of an aerosol agent in which an aerosol composition composed of a stock solution and a propellant is filled in a pressure-resistant container, and the stock solution contains an inorganic powder and a hydroxy group as active ingredients. Alternatively, it contains at least one of a solvent having a ketone group and a silicone powder. Hereinafter, each component will be described.
（原液）
　原液は、上記したように少なくとも無機粉体と、ヒドロキシ基又はケトン基を有する溶剤及びシリコーン粉体のうちの少なくとも一方を含有する。 (Stock solution)
As described above, the stock solution contains at least an inorganic powder and at least one of a solvent having a hydroxy group or a ketone group and a silicone powder.
　本発明において、無機粉体は有鱗目動物を忌避する有効成分である。例えば有鱗目動物がヤモリである場合、ヤモリの足はその表面が非常に細い毛で覆われており、この分子間力により垂直や逆さまの壁でも登ることができるが、無機粉体はヤモリの足の表面の細い毛の隙間に入り込み、ヤモリが壁に張り付く際の分子間力を減少させ、物理的にヤモリを忌避することができる。 In the present invention, the inorganic powder is an active ingredient that repels scaled reptiles. For example, when the scaled reptile is a gecko, the surface of the gecko's legs is covered with very fine hair, and this intermolecular force allows it to climb even on vertical or upside-down walls, but the inorganic powder is a gecko. It can penetrate into the gaps between the fine hairs on the surface of the gecko, reduce the intermolecular force when the gecko sticks to the wall, and physically repel the gecko.
　無機粉体としては、例えば、シリカ（二酸化ケイ素）、アルミナ、酸化亜鉛、酸化チタン、酸化マグネシウム、水酸化アルミニウム、炭酸カルシウム、タルク、マイカ、パーライト、ケイ酸、ケイ酸塩（ケイ酸マグネシウム、ケイ酸カルシウム等）、カオリン等が挙げられ、これらからなる群から選択される少なくとも１つを用いることができる。中でも、壁等の処理対象への付着性の観点から、シリカ、炭酸カルシウム及びタルクからなる群から選択される少なくとも１つを用いることが好ましい。 Examples of the inorganic powder include silica (silicon dioxide), alumina, zinc oxide, titanium oxide, magnesium oxide, aluminum hydroxide, calcium carbonate, talc, mica, pearlite, silicic acid, and silicate (silicic acid, silica). Calcium silicate and the like), kaolin and the like, and at least one selected from the group consisting of these can be used. Above all, from the viewpoint of adhesion to a treatment target such as a wall, it is preferable to use at least one selected from the group consisting of silica, calcium carbonate and talc.
　無機粉体の平均粒子径は、エアゾール剤の噴口等への目詰まりを抑制できる範囲であれば特に限定されないが、例えば、０．１～１００μｍの範囲であることが好ましく、０．１～５０μｍがより好ましく、１～２０μｍがさらに好ましい。前記範囲であると、処理対象の表面に均一に付着させることができ、また、処理対象の表面を汚すことがない。無機粉体の平均粒子径は、例えば、コールターカウンター法やレーザー回折散乱法による粒度分布測定により測定することができる。 The average particle size of the inorganic powder is not particularly limited as long as it can suppress clogging of the aerosol agent into the nozzle or the like, but is preferably in the range of 0.1 to 100 μm, preferably 0.1 to 50 μm. Is more preferable, and 1 to 20 μm is even more preferable. Within the above range, it can be uniformly adhered to the surface of the treatment target, and the surface of the treatment target is not soiled. The average particle size of the inorganic powder can be measured, for example, by measuring the particle size distribution by the Coulter counter method or the laser diffraction / scattering method.
　無機粉体は、原液中、０．７５～２０質量％（ｗ／ｗ％）の範囲で含有することが好ましい。原液中、無機粉体が０．７５質量％以上であると、原液を撹拌した時に無機粉体の拡散が容易に確認できるので、エアゾール剤の製造にあたって耐圧容器へ充填する際に原液の均一性の確認が容易である。また、無機粉体の含有量が多くなりすぎると原液の撹拌性が低下し、安定製造がし難くなるので、２０質量％以下が好ましい。無機粉体の含有量は、原液中、１質量％以上がより好ましく、１．５質量％以上がさらに好ましく、また、１５質量％以下がより好ましく、７質量％以下がさらに好ましい。 The inorganic powder is preferably contained in the stock solution in the range of 0.75 to 20% by mass (w / w%). If the content of the inorganic powder in the stock solution is 0.75% by mass or more, the diffusion of the inorganic powder can be easily confirmed when the stock solution is agitated. Is easy to confirm. Further, if the content of the inorganic powder is too large, the stirring property of the stock solution is lowered and stable production becomes difficult. Therefore, 20% by mass or less is preferable. The content of the inorganic powder in the stock solution is more preferably 1% by mass or more, further preferably 1.5% by mass or more, still more preferably 15% by mass or less, still more preferably 7% by mass or less.
　なお、エアゾール組成物中の無機粉体の含有量は、０．２５～１０質量％の範囲が好ましく、０．２８～７．５質量％がより好ましく、０．３～３．５質量％がさらに好ましい。無機粉体のエアゾール組成物中の含有量が０．２５質量％以上であると、処理対象の表面に満遍なく無機粉体を付着させることができるので、有鱗目動物の忌避効果を十分に得ることができる。またエアゾール組成物中での無機粉体の再分散性が悪いとエアゾール剤を使用し始めたときに無機粉体が多く噴射され、それを繰り返すうちに使用終期には無機粉体の噴射量が少なくなり、使用初期のような効果が得られなくなることがある。無機粉体のエアゾール組成物中の含有量が１０質量％以下であると、エアゾール剤中で無機粉体を再分散させやすいので、噴射量が安定し、使用初期と使用終期とで効果に差が出ることがない。 The content of the inorganic powder in the aerosol composition is preferably in the range of 0.25 to 10% by mass, more preferably 0.28 to 7.5% by mass, and preferably 0.3 to 3.5% by mass. More preferred. When the content of the inorganic powder in the aerosol composition is 0.25% by mass or more, the inorganic powder can be evenly adhered to the surface to be treated, so that a sufficient repellent effect for scaled reptiles can be obtained. be able to. In addition, if the redispersibility of the inorganic powder in the aerosol composition is poor, a large amount of the inorganic powder is sprayed when the aerosol agent is started to be used, and as this is repeated, the spray amount of the inorganic powder increases at the end of use. It may be reduced and the effect as in the initial stage of use may not be obtained. When the content of the inorganic powder in the aerosol composition is 10% by mass or less, the inorganic powder is easily redispersed in the aerosol agent, so that the injection amount is stable and the effect is different between the initial stage of use and the final stage of use. Does not appear.

The dispersibility of the body can be improved, and the redispersibility can also be improved. Further, when the content of the solvent is 65% by mass or less, the caking of the undiluted solution can be suppressed.

　なお、内圧は、エアゾール剤の温度を、恒温室等で保管して２５℃に設定し、圧力計（例えば、ＷＧＡ－７１０Ｃ計装用コンディショナ（株式会社共和電業製）に取り付けたＰＧＭ－Ｅ小型圧力センサ（株式会社共和電業製））により測定できる。 (Aerosol internal pressure)
The internal pressure of the aerosol agent is preferably 0.1 to 0.7 MPa, more preferably 0.15 to 0.6 MPa, still more preferably 0.2 to 0.6 MPa at an internal pressure of 25 ° C.

As for the internal pressure, the temperature of the aerosol agent was stored in a constant temperature room or the like, set to 25 ° C., and attached to a pressure sensor (for example, WGA-710C instrumentation conditioner (manufactured by Kyowa Electric Co., Ltd.))

（噴射圧）
　エアゾール剤の噴射圧は、噴口から５ｃｍ離れた位置における測定で、５～６００ｇｆであることが好ましく、８～５００ｇｆがより好ましい。噴射圧が強すぎると、無機粉体が処理対象に付着せず落下や飛散してしまうおそれがあるので忌避効果が十分に得られず、また噴射圧が弱すぎると処理対象に噴射が届かずに無機粉体が付着せず十分な忌避効果が得られないため、前記範囲であることが好ましい。
　なお、前記噴射圧は、エアゾール剤の噴口から鉛直方向に５ｃｍの距離を置いたところにデジタルフォースゲージ（例えば、株式会社イマダ製、型番：ＤＳ２－２Ｎ）に装着した直径６ｃｍの円状の平板を設置し、２５℃の室温条件下で、前記平板の中心に向かってエアゾール組成物を噴射した際の最大値を噴射荷重とし、複数回測定した噴射荷重の平均を算出することにより測定できる。 (Injection pressure)
The injection pressure of the aerosol agent is preferably 5 to 600 gf, more preferably 8 to 500 gf, as measured at a position 5 cm away from the injection port. If the injection pressure is too strong, the inorganic powder may not adhere to the treatment target and may fall or scatter, so a sufficient repellent effect cannot be obtained, and if the injection pressure is too weak, the injection will not reach the treatment target. The above range is preferable because the inorganic powder does not adhere to the powder and a sufficient repellent effect cannot be obtained.
The injection pressure is a circular flat plate with a diameter of 6 cm attached to a digital force gauge (for example, manufactured by Imada Co., Ltd., model number: DS2-2N) at a distance of 5 cm in the vertical direction from the injection port of the aerosol agent.

　エアゾール剤の噴射量は、０．５～１１ｇ／秒となるようにするのが好ましく、０．７～９ｇ／秒がより好ましく、１～７ｇ／秒がさらに好ましい。噴射量が０．５ｇ／秒以上であると、無機粉体の拡散性が低いので、忌避に十分な量を処理対象に付着させやすく、処理対象である床や壁等が垂直面であっても十分に付着させることができる。また、１１ｇ／秒を超えると無機粉体の拡散性が強くなり使用者が噴射されたエアゾール組成物を吸入する恐れがあるので、噴射量は１１ｇ／秒以下とするのが好ましい。 (Injection amount)
The injection amount of the aerosol agent is preferably 0.5 to 11 g / sec, more preferably 0.7 to 9 g / sec, and even more preferably 1 to 7 g / sec. When the injection amount is 0.5 g / sec or more, the diffusibility of the inorganic powder is low, so that a sufficient amount for repellent can be easily attached to the treatment target, and even if the floor or wall to be treated is a vertical surface. It can be sufficiently adhered. Further, if it exceeds 11 g / sec, the diffusivity of the inorganic powder becomes strong and the user may inhale the injected aerosol composition. Therefore, the injection amount is preferably 11 g / sec or less.
　噴射量を調整する方法としては、例えば、噴射ボタンの噴口の大きさを調整する方法、エアゾール剤の噴射圧を調整する方法、エアゾールバルブのステム孔径を調整する方法、噴射剤の圧力を調整する方法、及びこれらの組み合せ等が挙げられる。 Examples of the method of adjusting the injection amount include a method of adjusting the size of the injection port of the injection button, a method of adjusting the injection pressure of the aerosol agent, a method of adjusting the stem hole diameter of the aerosol valve, and a method of adjusting the pressure of the injection agent.
