Description
本発明は、匍匐害虫用忌避剤に関する。 The present invention relates to a repellent for crawling pests.
アリやゴキブリなどの匍匐害虫は、食品を餌として好む。日常生活において、アリやゴキブリなどの匍匐害虫が食品を嗅ぎ付け、食事の場に現れる、または食品に関する装置に侵入するなど問題となる場合が多い。
前記匍匐害虫を忌避するに際し、消費者の安全志向、天然物志向が強まっており、これら要求を満たす忌避成分として、テルペン系化合物のファルネシルアセトンが注目されている。
Creeping pests such as ants and cockroaches like to feed on food. In everyday life, creeping pests such as ants and cockroaches often cause problems by sniffing out food, appearing at eating places, or invading food-related equipment.
In repelling the crawling insects, consumers are increasingly conscious of safety and natural products, and farnesyl acetone, a terpene compound, has attracted attention as a repellent component that satisfies these demands.
例えば特許文献1の実施例12には、ファルネシルアセトンを熱可塑性樹脂に含有したシートが開示されている。 For example, Example 12 of Patent Document 1 discloses a sheet containing farnesyl acetone in a thermoplastic resin.
しかしながら、前記シートでは匍匐害虫に対して十分な忌避効果を得られないことがあり、より優れた匍匐害虫用忌避剤が求められていた。 However, the above-mentioned sheets may not provide sufficient repellent effect against crawling pests, and there is a demand for a better repellent for crawling pests.
本発明は、上記問題点に鑑み、匍匐害虫に対して優れた忌避効果を発揮する忌避剤を提供するものである。 In view of the above problems, the present invention provides a repellent that exhibits excellent repellent effects against crawling pests.
本発明者は、上記課題を満足するために鋭意検討した結果、ファルネシルアセトンを含有した樹脂成形体表面から1日あたり4~110μg/cm2のファルネシルアセトンをブリードさせることで、匍匐害虫に対して優れた忌避効果を発揮することを見出した。 As a result of intensive research to achieve the above object, the present inventors have found that by bleeding 4 to 110 μg/ cm2 of farnesyl acetone per day from the surface of a resin molded article containing farnesyl acetone, an excellent repellent effect against crawling pests can be achieved.
本発明は、匍匐害虫に対して優れた忌避効力を発揮する。さらには本発明の匍匐害虫用忌避剤に接触しても薬剤の汚損が抑制されているので、例えば、衣服、陶器、金属などを薬剤で汚損する心配が少ない。このため本発明の匍匐害虫用忌避剤は、使用場面を考慮することなく使用することができる。 The present invention exerts an excellent repellent effect against crawling pests. Furthermore, since the agent is prevented from being stained even when it comes into contact with the crawling pest repellent of the present invention, there is little concern that the agent will stain, for example, clothes, pottery, metal, etc. Therefore, the crawling pest repellent of the present invention can be used without considering the situation of use.
本発明の匍匐害虫用忌避剤は、ファルネシルアセトンを含有する樹脂成形体表面から1日あたり4~110μg/cm2のファルネシルアセトンがブリードしてなるものである。 The creeping insect repellent of the present invention is obtained by bleeding out 4 to 110 μg/cm 2 of farnesyl acetone per day from the surface of a resin molded article containing farnesyl acetone.
前記樹脂成形体表面からの1日あたりのファルネシルアセトンのブリード量は、匍匐害虫用忌避剤の全面を1mLのヘプタンをしみこませたパルプ製ワイプで拭き取った後直射日光が当たらない25℃の室内に1日静置し、その後ヘプタンを染み込ませたパルプ製ワイプを用いて該匍匐害虫用忌避剤の一部の面または全面を拭き取り、拭き取り後のパルプ製ワイプからファルネシルアセトンを抽出し、ガスクロマトグラフにより定量分析する。そして、定量分析されたファルネシルアセトン量を拭き取った面の面積で除することで算出できる。 The amount of farnesyl acetone bleeding from the surface of the resin molded body per day can be calculated by wiping the entire surface of the crawling insect repellent with a pulp wipe soaked in 1 mL of heptane, leaving it to stand for one day in a room at 25°C away from direct sunlight, then wiping a portion or the entire surface of the crawling insect repellent with the pulp wipe soaked in heptane, extracting farnesyl acetone from the pulp wipe after wiping, and quantitatively analyzing it by gas chromatography. The quantitatively analyzed amount of farnesyl acetone can then be calculated by dividing the area of the wiped surface.
