Description

本発明は、衣料用防虫およびダニ忌避剤に関するものである。 The present invention relates to an insect repellent for clothes and a tick repellent.

従来、イガ類、カツオブシムシ類やシミ類等の衣料害虫から繊維製品を保護するため、主に、タンス、引き出し、クローゼットや衣類収納箱用として、様々な防虫剤が実用化されている。その有効成分としては、古くはp−ジクロロベンゼンやナフタレン等の昇華性防虫成分が使用されたが、安全性の問題や強い刺激臭が指摘され、エムペントリンやプロフルトリン等の常温揮散性ピレスロイド系殺虫成分が主流となっている。後者のピレスロイド系殺虫成分は、無臭で衣料害虫に対して微量で高い殺虫効力を奏し、しかも安全性にも優れ有用性の高い有効成分である。
近年、消費者のニーズが多様化し、無臭よりも幾分かの芳香性を有する防虫剤を使用して、処理空間や衣類への賦香を積極的に行う傾向も見られるようになっている。
Conventionally, various insect repellents have been put to practical use mainly for chiffons, drawers, closets, and clothing storage boxes in order to protect textile products from garment pests such as moths, cutworms, and stains. As its active ingredients, sublimable insect repellents such as p-dichlorobenzene and naphthalene were used in the past, but safety problems and strong irritating odors were pointed out, and room temperature volatile pyrethroid insecticides such as empentrin and profluthrin Has become the mainstream. The latter pyrethroid insecticidal component is an effective component that is odorless and exhibits a high amount of insecticidal effect against clothing pests, and is excellent in safety and highly useful.
In recent years, consumer needs have diversified, and there is a tendency to actively perfume treatment spaces and clothing using insect repellents that have some fragrance rather than odorlessness. .

このような状況を背景として、防虫効果と芳香性を兼ね備える天然精油や香料成分を防虫成分として用いる提案がいくつかなされている。
例えば、特開昭50−24436号では、リナロール、アネトール、メントール、シンナミックアルデヒド、チモール、オイゲノールが、特公昭57−5761号にはアネトール、オイゲノール、アニスアルデヒドジメチルアセタール、p−イソプロピルアニソール、イソカベビトール、1,4−ジエトキシベンゼンが、特開平7−112907号では、リナロール、ゲラニオール、ボルネオール、ネロリドール、ネロール、α−テルピネオール、ペリラアルデヒド、シトラール、樟脳、α−ヨノン、1,8−シネオール、リナロールオキサイドまたはシトラールジエチルアセタールを防虫剤の有効成分として使用することが記載されている。また、特許第4311773号公報では、衣料害虫の孵化抑制剤に着目し、卵から幼虫への移行を抑制すれば衣料害虫による食害を防止できると考え、卵孵化抑制剤として、リナロ−ル、ゲラニオ−ル、シトロネラ−ル、ヘプタン酸アリル、酢酸ネリル等、数多くのテルペン化合物が提案されている。
また、一方で衣料用防虫剤について従来の機能に付加価値を付けて、より多機能な効果を有する衣料用防虫剤の開発が試みられている。
例えば衣料用防虫剤に防カビ成分を付与したものや(特開2014−136685号公報)、消臭効果を付与したものなどがあげられる。このような背景の下で、1つの製品で、衣料害虫に対する効果だけでなく、防ダニ効果として屋内のダニに対する忌避効果も付与できれば、生活の場で利便性が大きいと考えた。
ただし衣料害虫に対する有効成分とダニに対する忌避成分を混ぜ合わせるだけでは、製造コストや得られる製剤の香調のバランスに問題が残り、さらには防虫効果にもダニ忌避効果についても満足するものは未だ認められていない。
Against this background, some proposals have been made to use natural essential oils and perfume ingredients having insect repellent effects and aromatic properties as insect repellent ingredients.
For example, JP-A-50-24436 discloses linalool, anethole, menthol, cinnamic aldehyde, thymol, eugenol, and JP-B-57-5761 discloses anethole, eugenol, anisaldehyde dimethyl acetal, p-isopropylanisole, isocabebitol, In JP-A-7-112907, 1,4-diethoxybenzene is linalool, geraniol, borneol, nerolidol, nerol, α-terpineol, perilaldehyde, citral, camphor, α-ionone, 1,8-cineol, linalool. It is described that oxide or citral diethyl acetal is used as an active ingredient of an insect repellent. Further, in Japanese Patent No. 4311773, attention is paid to a hatching inhibitor for clothing pests, and it is considered that if the migration from eggs to larvae is suppressed, feeding damage caused by clothing pests can be prevented. Numerous terpene compounds have been proposed, such as thiol, citronellal, allyl heptanoate and neryl acetate.
On the other hand, an attempt has been made to develop an insect repellent for clothing having a more multifunctional effect by adding value to the conventional functions of the insect repellent for clothing.
For example, the thing which added the fungicide component to the insect repellent for clothing (Japanese Unexamined Patent Publication No. 2014-136585), the thing which provided the deodorizing effect, etc. are mention | raise | lifted. Under such circumstances, we thought that if one product could provide not only an effect on clothing pests but also a repellent effect on indoor mites as an anti-mite effect, it would be convenient in daily life.
However, just mixing the active ingredients against clothing pests and the repellent ingredients against mites leaves problems in the balance of manufacturing costs and the fragrance of the resulting preparations, and there are still some that satisfy both insect repellent and mite repellent effects. It is not done.

本発明は、衣料害虫防除効果とダニ忌避効果を兼ね備えた、衣料用防虫およびダニ忌避剤について、衣類の保管に適した香りを付与できる香料成分を含有する衣料用防虫およびダニ忌避剤を提供することを目的とする。 The present invention provides an insect repellent for clothes and a tick repellent containing a perfume ingredient capable of imparting a scent suitable for storage of clothes, for an insect repellent for clothes and a tick repellent having both a pest control effect and a tick repellent effect For the purpose.

本発明は、上記目的を達成するために、各種香料成分を検討したところ、3−メチル−5−フェニル−1−ペンタノールが単一成分であっても、衣料害虫防除効果とダニ忌避効果を兼ね備えていることを見出した。さらには、この3−メチル−5−フェニル−1−ペンタノールに、本来ダニ忌避効果を有さないカルボン酸アリルエステル化合物を併用することにより、ダニ忌避効果が高まることを見出したものであり、以下の構成を有する。
(1)3−メチル−5−フェニル−1−ペンタノールを含有することを特徴とする衣料用防虫およびダニ忌避剤。
(2)前記3−メチル−5−フェニル−1−ペンタノールに加え、ダニ忌避活性増強成分としてカルボン酸アリルエステル化合物を含有することを特徴とする(1)に記載の衣料用防虫およびダニ忌避剤。
(3)前記カルボン酸アリルエステル化合物が、ヘキサン酸アリル、ヘプタン酸アリル、オクタン酸アリルから選ばれる1種または2種以上であることを特徴とする(2)に記載の衣料用防虫およびダニ忌避剤。
In order to achieve the above-mentioned object, the present invention has studied various fragrance ingredients. As a result, even if 3-methyl-5-phenyl-1-pentanol is a single ingredient, it has a garment pest control effect and a tick repellency effect. I found out that I have both. Furthermore, it has been found that the mite repellent effect is enhanced by using this 3-methyl-5-phenyl-1-pentanol together with a carboxylic acid allyl ester compound that does not originally have a mite repellent effect, It has the following configuration.
(1) An insect repellent and a tick repellent for clothing comprising 3-methyl-5-phenyl-1-pentanol.
(2) In addition to the 3-methyl-5-phenyl-1-pentanol, a carboxylic acid allyl ester compound is contained as a tick repellent activity enhancing component, and the insect repellent and tick repellent according to (1) Agent.

本発明の衣料用防虫およびダニ忌避剤の成分である3−メチル−5−フェニル−1−ペンタノールは、衣料害虫に対する活性を持つ香料成分としては公知であるが(特開2014−136685号公報)、衣料害虫に対する活性に加えダニ忌避活性を有することは知られていない。さらには、本来ダニ忌避効果を有さないカルボン酸アリルエステル化合物を3−メチル−5−フェニル−1−ペンタノールと併用することにより、ダニ忌避効果が高まるという新たな知見が得られたことから、その実用性は極めて高い。 Although 3-methyl-5-phenyl-1-pentanol, which is a component of the insect repellent and tick repellent of the present invention, is known as a perfume component having activity against clothing pests (Japanese Patent Laid-Open No. 2014-136665) ), It is not known to have tick repellent activity in addition to activity against clothing pests. Furthermore, a new finding that the mite repellent effect is enhanced by using a carboxylic acid allyl ester compound, which originally has no mite repellent effect, in combination with 3-methyl-5-phenyl-1-pentanol was obtained. , Its practicality is extremely high.

本発明の衣料用防虫およびダニ忌避剤は、有効成分として3−メチル−5−フェニル−1−ペンタノールを含有することを特徴とする。 The insect repellent for clothes and the tick repellent of the present invention are characterized by containing 3-methyl-5-phenyl-1-pentanol as an active ingredient.

本発明者らは種々の香料成分を衣料害虫用防虫活性と同時にダニ忌避についてスクリーニングした結果、3−メチル−5−フェニル−1−ペンタノールが衣料害虫に対する防虫活性に加え、ダニに対する忌避活性をも同時に認めたことから、ダニ忌避活性も備えた衣料用防虫剤の成分として使用できることを新たに見出したものである。 As a result of screening the various perfume ingredients for insect pests for clothing pests at the same time as mite repellent, 3-methyl-5-phenyl-1-pentanol has a repellent activity against mites in addition to the insect repellent activity against clothing pests. Was also found at the same time, and it was newly found that it can be used as a component of an insect repellent for clothing having mite repellent activity.

なお、本発明で言う衣料害虫用防虫活性とは、衣料害虫の幼虫や成虫に対する殺虫効果だけでなく、忌避効果や衣類等への侵入・食害防止効果をも含めた総合的な効果を包摂するものとする。さらにダニ忌避活性とは、ダニを衣料等へ近づけさせず、侵入、定着を阻止する効果をも含めた総合的な効果を包摂するものとする。 In addition, the insecticidal activity for clothing pests referred to in the present invention encompasses not only the insecticidal effect of clothing pests against larvae and adults, but also comprehensive effects including repellent effects and effects of preventing invasion and eating damage to clothing, etc. Shall. Furthermore, the mite repellent activity includes a comprehensive effect including an effect of preventing invasion and colonization without bringing mites closer to clothing and the like.

本発明の衣料用防虫およびダニ忌避剤には、上記3−メチル−5−フェニル−1−ペンタノールほかに、本3−メチル−5−フェニル−1−ペンタノールのダニ忌避活性増強成分としてカルボン酸アリルエステル化合物を含有することを特徴とする。
本3−メチル−5−フェニル−1−ペンタノールのダニ忌避活性増強成分としての本カルボン酸アリルエステル化合物は、衣料害虫に対して防虫活性を有し、それ単独ではダニ忌避活性を認めないものの、本発明の3−メチル−5−フェニル−1−ペンタノールと併用することにより、3−メチル−5−フェニル−1−ペンタノールのダニ忌避活性を高めるものである。
カルボン酸アリルエステル化合物としては具体的には、シクロヘキシルプロピオン酸アリル、ヘキサン酸アリル、ヘプタン酸アリル、オクタン酸アリルが挙げられるが、中でもヘキサン酸アリル、ヘプタン酸アリル、オクタン酸アリルが好ましい。

Intrusion prevention rate (%) = [number of invading ticks in untreated area−number of invading ticks in treated area] / number of invading ticks in untreated area × 100
And the mite repellent effect of each fragrance | flavor component was further evaluated from the obtained penetration | inhibition prevention rate on the following references | standards.
◎: Intrusion prevention rate 90-100%, ○: Intrusion prevention rate 70-90%, △: Intrusion prevention rate 50-70%, x: Intrusion prevention rate <50%

衣料害虫防虫効力試験およびダニ忌避効力試験の結果を表1に示した。
Table 1 shows the results of the insect pest control test and the tick repellent test.

試験の結果、3−メチル−5−フェニル−1−ペンタノールは単独の成分で衣料害虫に対して致死効果を示し、加えて屋内塵性ダニに対しても忌避効果を示した(実施例1)。
3−メチル−5−フェニル−1−ペンタノールのダニに対する忌避活性は、単独ではダニ剤に対する忌避活性評価の低いカルボン酸アリルエステル化合物(比較例3〜5)を加えることにより顕著に増加することが明らかになった(実施例2〜4)。
このカルボン酸アリルエステル化合物によるダニ忌避活性増強作用は、他の香料成分であるエチルベンゾエートやゲラニオールとの併用では効果が認められず(比較例7〜10)、また末端が環状であるシクロヘキシルプロピオン酸アリルを用いた場合では3−メチル−5−フェニル−1−ペンタノールのダニ忌避活性増強作用は認められなかった(実施例5)。
As a result of the test, 3-methyl-5-phenyl-1-pentanol is a single component and has a lethal effect on clothing pests, and also has a repellent effect on indoor dust mites (Example 1). ).
The repellent activity against mites of 3-methyl-5-phenyl-1-pentanol is remarkably increased by adding a carboxylic acid allyl ester compound (Comparative Examples 3 to 5) having a low repellent activity evaluation against mite alone. Became clear (Examples 2 to 4).
The mite repellent activity enhancing action by this carboxylic acid allyl ester compound is not recognized in combination with other fragrance components such as ethyl benzoate and geraniol (Comparative Examples 7 to 10), and cyclohexylpropionic acid having a cyclic end. In the case of using allyl, the effect of enhancing the mite repellent activity of 3-methyl-5-phenyl-1-pentanol was not observed (Example 5).

衣料用防虫成分の3−メチル−5−フェニル−1−ペンタノール20質量%、及びオクタン酸アリル10質量%、を配合した衣料用防虫およびダニ忌避組成物を調製した。
次に、この衣料用防虫およびダニ忌避組成物10gに、界面活性剤として、ポリオキシエチレンラウリルエーテル5.0g、ポリエキシエチレン硬化ヒマシ油2.0g、及びラウリン酸アミドプロピルアミンオキシド1.8gを加え、さらに溶剤としてエタノール20g、消臭成分として緑茶抽出物1.5g、安定剤としてBHT1.9g、微量のイソチアゾリン系防腐剤、微量の苦味剤(ビトレックス)、及び適量の水を配合し、全体を386gとして含浸液を調製した。
An insect repellent and tick repellent composition for clothing containing 20% by mass of 3-methyl-5-phenyl-1-pentanol and 10% by mass of allyl octoate as insect repellent ingredients for clothing was prepared.
Next, 10 g of this insect repellent and mite repellent composition was coated with 5.0 g of polyoxyethylene lauryl ether, 2.0 g of polyoxyethylene hydrogenated castor oil, and 1.8 g of lauric acid amidopropylamine oxide as surfactants. In addition, 20 g of ethanol as a solvent, 1.5 g of green tea extract as a deodorant component, 1.9 g of BHT as a stabilizer, a trace amount of isothiazoline preservative, a trace amount of bitterness (vitrex), and an appropriate amount of water are blended, The impregnating solution was prepared with a total of 386 g.

上面に総面積24cmの開口部を有し、容量が500mLの円筒状のプラスチック容器(φ:8cm、高さ:10cm)に、吸水性ポリマーとして、粒径が約2mmのアクリル酸/アクリル酸ナトリウム塩共重合体14gを入れた。これに上記含浸液を注ぎ込んだところ、吸水性ポリマーが膨潤し、粒径が約10mmの本発明の水性ゲルビーズタイプの衣料用防虫およびダニ忌避剤が得られた。 Acrylic acid / acrylic acid having a particle size of about 2 mm as a water-absorbing polymer in a cylindrical plastic container (φ: 8 cm, height: 10 cm) having an opening with a total area of 24 cm 2 on the upper surface and a capacity of 500 mL 14 g of sodium salt copolymer was added. When the above impregnating solution was poured into this, the water-absorbing polymer swelled, and the water-based gel bead type insect repellent and tick repellent of the present invention having a particle size of about 10 mm were obtained.

この水性ゲルビーズタイプの衣料用防虫およびダニ忌避剤をクローゼット内に置いて使用したところ、約1年間に亘って衣類に虫による害が発生せず、実用的な防虫効果が確認された。またクローゼット内には、ダニの寄り付きも認められなかった。この水性ゲルビーズは、時間の経過とともに徐々に縮小したが、変質や離液を伴うことがなくゲル安定性に優れ、使用の終点も明確に視認できた。また、クローゼット内には初期香調のままの芳香が漂い、快適な爽やかさを周囲に提供することができ、極めて実用性の高いものであった。 When this water-based gel bead type insect repellent and tick repellent were placed in a closet and used for about one year, insects were not damaged by insects, and a practical insect repellent effect was confirmed. Also, no tick was found in the closet. The aqueous gel beads were gradually reduced with the passage of time. However, the aqueous gel beads were excellent in gel stability without any alteration or separation, and the end point of use was clearly visible. In addition, there was a fragrance in the initial scent in the closet, and it was possible to provide a comfortable freshness to the surroundings, which was extremely practical.

本発明は、衣料用防虫およびダニ忌避剤としてだけでなく、広範な害虫防虫剤としても利用可能である。


The present invention can be used not only as an insect repellent and a tick repellent for clothing but also as a wide range of insect repellents.
