Description
本発明は、蚊、ブヨ、サシバエ、イエダニ、ナンキンムシ等の害虫から人体や動物を守るためのパウダー状害虫忌避組成物、及びその製造方法に関する。 The present invention relates to a powdery pest repellent composition for protecting human bodies and animals from pests such as mosquitoes, gnats, sand flies, house dust mites, bedbugs, and the like, and a method for producing the same.
従来の害虫忌避製品は、アルコールをベースとしたエアゾールタイプのものが主流であった。例えば、従来のエアゾールタイプの害虫忌避製品として、特許文献１及び特許文献２が知られている。特許文献１の害虫忌避組成物は、無機粉末又は有機粉末と無水ケイ酸とを特定の比率で配合し、これを害虫忌避成分、アルコール、噴射剤とともにエアゾール容器に充填したものである。特許文献２の忌避剤組成物は、無水ケイ酸多孔質微粒子に害虫忌避剤を担持させ、これを合成樹脂微粒子、アルコール、噴射剤とともにエアゾール容器に充填したものである。また、エアゾールタイプ以外の害虫忌避製品として、特許文献３のようなウェットティッシュタイプの製品も開発されている。特許文献３の害虫忌避剤は、不織布に、ケイ酸化合物、害虫忌避成分、アルコールを含浸させたものである。 Conventional pest repellent products are mainly aerosol type alcohol-based products. For example, Patent Literature 1 and Patent Literature 2 are known as conventional aerosol type pest repellent products. The pest repellent composition of Patent Document 1 is a mixture of inorganic powder or organic powder and anhydrous silicic acid in a specific ratio, which is filled in an aerosol container together with pest repellent components, alcohol, and propellant. In the repellent composition of Patent Document 2, a pest repellent is supported on silicic anhydride porous fine particles, and this is filled in an aerosol container together with synthetic resin fine particles, alcohol and a propellant. In addition, as a pest repellent product other than the aerosol type, a wet tissue type product as in Patent Document 3 has also been developed. The pest repellent of Patent Document 3 is obtained by impregnating a nonwoven fabric with a silicate compound, a pest repellent component, and alcohol.
しかしながら、特許文献１及び特許文献２のようなエアゾールタイプの害虫忌避製品は、害虫忌避成分を微粒子化して皮膚面に噴霧するため、塗布面の塗りむらが生じ易くなる。その結果、皮膚に薬剤が付着しない僅かな部分が発生することがあり、この僅かな部分において蚊の刺咬、吸血行動を招く虞がある。また、アルコールや害虫忌避成分を含む害虫忌避組成物（薬剤）の飛散によって鼻粘膜に刺激を感じることがあり、使用感の点において改善が求められる。特許文献３の害虫忌避剤は、エアゾールタイプではないため、薬剤の飛散の問題は少ないが、特許文献１及び特許文献２の害虫忌避製品と同様にアルコールを使用しているため、アルコール等の刺激に過敏な人にとっては依然として使い辛いものである。 However, aerosol-type pest repellent products such as Patent Document 1 and Patent Document 2 make the pest repellent component fine particles and spray them onto the skin surface, so that uneven coating of the coated surface is likely to occur. As a result, a slight portion where the drug does not adhere to the skin may occur, and this small portion may lead to mosquito biting and blood sucking behavior. In addition, the nasal mucosa may be irritated by the scattering of a pest repellent composition (medicine) containing alcohol and a pest repellent component, and improvement is required in terms of usability. Since the insect repellent of Patent Document 3 is not an aerosol type, there is little problem of scattering of the drug, but since alcohol is used in the same manner as the insect repellent products of Patent Document 1 and Patent Document 2, stimulation of alcohol or the like It's still hard to use for those who are sensitive.
このような理由から、最近では、薬剤が飛散し難く、アルコールを使用しないタイプの害虫忌避製品を求めるニーズが増加しつつある。本発明は、上記問題点に鑑みてなされたものであり、害虫忌避組成物の製品形態としてパウダータイプに着目し、害虫忌避効果、及び人体や動物への安全性に優れていることは勿論のこと、使用感や持続性の点でも満足のいくアルコールフリーのパウダー状害虫忌避組成物、及びその製造方法を提供することを目的とする。 For these reasons, recently, there is an increasing need for a pest repellent product that does not easily scatter drugs and does not use alcohol. The present invention has been made in view of the above problems, focusing on the powder type as the product form of the pest repellent composition, and of course has excellent pest repellent effect and safety to human bodies and animals. Another object of the present invention is to provide an alcohol-free powdery pest repellent composition that is satisfactory in terms of usability and sustainability, and a method for producing the same.

本発明のパウダー状害虫忌避組成物は、基本的な成分として、（１）害虫忌避剤、（２）刺激緩和剤、（３）水分保持剤、及び（４）油分吸収剤を含有する。一方、本発明のパウダー状害虫忌避組成物は、エタノール、イソプロパノール、プロパノール等のアルコールを含まない。以下、本発明のパウダー状害虫忌避組成物の各成分について詳細に説明する。 The powdery pest repellent composition of the present invention contains (1) a pest repellent, (2) a stimulant mitigating agent, (3) a water retention agent, and (4) an oil absorbent as basic components. On the other hand, the powdery pest repellent composition of the present invention does not contain alcohols such as ethanol, isopropanol, and propanol. Hereinafter, each component of the powdery pest repellent composition of the present invention will be described in detail.
（１）害虫忌避剤
害虫忌避剤は、害虫に対して忌避作用や吸血阻害作用を有する物質である。害虫忌避剤の例として、ディート、３−（Ｎ−ｎ−ブチル−Ｎ−アセチル）アミノプロピオン酸エチルエステル、イカリジン、ピカリディン、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、ｐ−メンタン−３，８−ジオール、α−ピネン、カンファー、ゲラニオール、カラン−３，４−ジオール等の合成化合物が挙げられる。また、桂皮、シトロネラ、レモングラス、クローバ、ベルガモット、月桂樹、ユーカリ等の天然物も使用可能である。天然物は、精油や抽出液などの形態で使用することができる。上掲の害虫忌避剤のうち、ディート、３−（Ｎ−ｎ−ブチル−Ｎ−アセチル）アミノプロピオン酸エチルエステル、及びイカリジンが好ましく使用される。ディートは、長年にわたる使用実績がある。３−（Ｎ−ｎ−ブチル−Ｎ−アセチル）アミノプロピオン酸エチルエステルは、ディートとほぼ同等の忌避効果を有しながら、ディートよりも人体に対する安全性が高い。イカリジンは、害虫忌避効果が高く、安全性も高い。なお、上掲の各害虫忌避剤は、単独で用いてもよいし、二種以上の混合物として用いてもよい。害虫忌避剤の配合量は、パウダー状害虫忌避組成物の全体量に対して１〜１５重量％、好ましくは３〜１４重量％、より好ましくは６〜１２重量％とされる。配合量が１重量％より少ない場合、十分な害虫忌避作用が得られない虞がある。配合量が１５重量％より多い場合、刺激が強くなり過ぎる虞がある。(1) Pest repellent A pest repellent is a substance having a repellent action and a blood sucking inhibitory action against pests. Examples of pest repellents include diet, 3- (Nn-butyl-N-acetyl) aminopropionic acid ethyl ester, icaridin, picaridin, citronellal, citronellol, citral, linalool, terpineol, menthol, p-menthane-3, Examples include synthetic compounds such as 8-diol, α-pinene, camphor, geraniol, and caran-3,4-diol. Natural products such as cinnamon bark, citronella, lemongrass, clover, bergamot, laurel and eucalyptus can also be used. Natural products can be used in the form of essential oils or extracts. Of the above-mentioned pest repellents, diet, 3- (Nn-butyl-N-acetyl) aminopropionic acid ethyl ester, and icaridin are preferably used. Diet has a long track record of use. 3- (Nn-butyl-N-acetyl) aminopropionic acid ethyl ester has a repellent effect substantially equivalent to that of diet, but has higher safety to human body than diet. Icaridine has a high insect repellent effect and high safety. Each of the above-mentioned pest repellents may be used alone or as a mixture of two or more. The compounding quantity of a pest repellent is 1-15 weight% with respect to the whole quantity of a powdery pest repellent composition, Preferably it is 3-14 weight%, More preferably, it is 6-12 weight%. If the blending amount is less than 1% by weight, a sufficient pest repellent action may not be obtained. If the blending amount is more than 15% by weight, the irritation may become too strong.
（２）刺激緩和剤
刺激緩和剤は、害虫忌避剤による皮膚への刺激を緩和するために添加される物質である。刺激緩和剤としては、グリコール系溶剤が使用される。グリコール系溶剤は、Ｃ3〜Ｃ6のグリコールが好ましく、例えば、ジエチレングリコール、プロピレングリコール、ジプロピレングリコール、１，３−ブチレングリコール等が挙げられる。これらのうち、刺激緩和作用が高い１，３−ブチレングリコールがより好ましく使用される。ちなみに、１，３−ブチレングリコールを初めとするＣ3〜Ｃ6のグリコールは、それ自体皮膚から吸収され難いので、害虫忌避剤の経皮吸収を軽減することにも有効となる。なお、上掲のグリコール系溶剤は、単独で用いてもよいし、二種以上の混合物として用いてもよい。刺激緩和剤の配合量は、パウダー状害虫忌避組成物の全体量に対して１〜１５重量％、好ましくは５〜１０重量％、より好ましくは６〜８重量％とされる。配合量が１重量％より少ない場合、害虫忌避剤の刺激を十分に緩和できない虞がある。配合量が１５重量％より多い場合、多量のグリコール系溶剤によってべとつき感が増大し、使用感が悪化することがある。(2) Irritation mitigating agent An irritation mitigating agent is a substance added to alleviate skin irritation caused by a pest repellent. A glycol solvent is used as the stimulant mitigating agent. The glycol solvent is preferably a C 3 to C 6 glycol, and examples thereof include diethylene glycol, propylene glycol, dipropylene glycol, and 1,3-butylene glycol. Of these, 1,3-butylene glycol having a high stimulus mitigating action is more preferably used. Incidentally, since C 3 -C 6 glycols such as 1,3-butylene glycol are difficult to be absorbed from the skin itself, it is also effective in reducing percutaneous absorption of pest repellents. The glycol solvents listed above may be used singly or as a mixture of two or more. The blending amount of the stimulant mitigating agent is 1 to 15% by weight, preferably 5 to 10% by weight, more preferably 6 to 8% by weight, based on the total amount of the powdery pest repellent composition. When the blending amount is less than 1% by weight, there is a possibility that the stimulation of the pest repellent cannot be sufficiently mitigated. When the blending amount is more than 15% by weight, the feeling of stickiness is increased by a large amount of glycol solvent, and the feeling of use may be deteriorated.
（３）水分保持剤
水分保持剤は、しっとりとした感触（いわゆる、しっとり感）を出すために添加される物質である。水分保持剤としては、タルクが使用される。タルクは、ＪＩＳ Ｋ５１０１に準拠して測定される見かけ比重が０．４〜０．６ｇ／ｃｃであることが好ましい。見かけ比重が０．４ｇ／ｃｃ未満の場合、しっとり感よりもべとつき感の方が強く感じられるようになり、使用感が悪化することがある。見かけ比重が０．６ｇ／ｃｃを超える場合、サラサラ感が強くなり、粉落ちする可能性がある。また、タルクの平均粒径は、２０μｍ以上であることが好ましい。平均粒径を２０μｍ以上とすることで、タルクが皮膚に確実に付着し、よりしっとり感を得ることができる。平均粒径が２０μｍ未満の場合、皮膚に塗布したときに害虫忌避組成物が白く目立つ、いわゆる、白残りが生じる場合がある。なお、タルクは、カオリン、ベントナイト等の他の無機粉末と混合した状態で使用することも可能である。水分保持剤の配合量は、パウダー状害虫忌避組成物の全体量に対して５０〜９０重量％、好ましくは５５〜８５重量％、より好ましくは６３〜８３．５重量％とされる。配合量が５０重量％より少ない場合、十分に水分を保持できなくなるため、粉落ちが発生する虞がある。配合量が９０重量％より多い場合、しっとり感よりもべとつき感の方が強く感じられるようになり、使用感が悪化することがある。(3) Moisture retention agent The moisture retention agent is a substance added to give a moist feel (so-called moist feeling). As the moisture retaining agent, talc is used. Talc preferably has an apparent specific gravity of 0.4 to 0.6 g / cc measured in accordance with JIS K5101. When the apparent specific gravity is less than 0.4 g / cc, the sticky feeling is felt stronger than the moist feeling, and the feeling of use may be deteriorated. When the apparent specific gravity exceeds 0.6 g / cc, the smoothness becomes stronger and the powder may fall off. Moreover, it is preferable that the average particle diameter of a talc is 20 micrometers or more. By setting the average particle size to 20 μm or more, talc can reliably adhere to the skin and a moist feeling can be obtained. When the average particle size is less than 20 μm, a so-called white residue may be generated in which the pest repellent composition stands out in white when applied to the skin. In addition, talc can also be used in the state mixed with other inorganic powders, such as kaolin and bentonite. The amount of the moisture retaining agent is 50 to 90% by weight, preferably 55 to 85% by weight, more preferably 63 to 83.5% by weight, based on the total amount of the powdery pest repellent composition. When the blending amount is less than 50% by weight, moisture cannot be sufficiently retained, and there is a possibility that powder falling off may occur. When the blending amount is more than 90% by weight, the sticky feeling becomes stronger than the moist feeling, and the feeling of use may be deteriorated.
（４）油分吸収剤
油分吸収剤は、皮脂等の油分を吸収するために添加される物質である。油分吸収剤としては、ケイ酸化合物が使用される、ケイ酸化合物は、無水ケイ酸、ケイ酸カルシウム、疎水性シリカ、ケイソウ土等が挙げられる。これらのうち、油分吸収効果が高い無水ケイ酸がより好ましく使用される。ケイ酸化合物は、比表面積が５〜１００ｍ2／ｇであることが好ましい。比表面積が５ｍ2／ｇ未満の場合、油分吸収能力が不足してべとつきを生じ易くなる。比表面積が１００ｍ2／ｇを超える場合、サラサラ感が強くなり、粉落ちする可能性がある。なお、上掲のケイ酸化合物は、単独で用いてもよいし、二種以上の混合物として用いてもよい。油分吸収剤の配合量は、パウダー状害虫忌避組成物の全体量に対して１〜５０重量％、好ましくは３〜３０重量％、より好ましくは４．５〜２１重量％とされる。配合量が１重量％より少ない場合、油分吸収能力が不足し、べとつきを生じ易くなる。配合量が５０重量％より多い場合、油分吸収能力が過剰となり、重みが感じられて使用感が悪化することがある。(4) Oil absorbent An oil absorbent is a substance added to absorb oil such as sebum. As the oil absorbent, a silicate compound is used. Examples of the silicate compound include anhydrous silicic acid, calcium silicate, hydrophobic silica, diatomaceous earth and the like. Of these, silicic anhydride having a high oil absorption effect is more preferably used. The silicic acid compound preferably has a specific surface area of 5 to 100 m 2 / g. When the specific surface area is less than 5 m 2 / g, the oil absorption capacity is insufficient and stickiness tends to occur. When the specific surface area exceeds 100 m 2 / g, the smoothness becomes stronger and the powder may fall off. The silicic acid compounds listed above may be used alone or as a mixture of two or more. The blending amount of the oil absorbent is 1 to 50% by weight, preferably 3 to 30% by weight, more preferably 4.5 to 21% by weight with respect to the total amount of the powdery pest repellent composition. If the blending amount is less than 1% by weight, the oil absorption capacity is insufficient, and stickiness tends to occur. When the blending amount is more than 50% by weight, the oil absorption capacity becomes excessive, the weight is felt, and the usability may be deteriorated.
本発明のパウダー状害虫忌避組成物は、上記の（１）害虫忌避剤、（２）刺激緩和剤、（３）水分保持剤、及び（４）油分吸収剤を原材料として、例えば、以下の手順により製造することができる。 The powdery pest repellent composition of the present invention is prepared from the above-mentioned (1) pest repellent, (2) irritation mitigating agent, (3) moisture retention agent, and (4) oil absorbent as raw materials. Can be manufactured.
初めに、害虫忌避剤及び刺激緩和剤を混合する（混合工程）。次に、混合工程により得られた混合物を、油分吸収剤に吸収させる（吸収工程）。さらに、吸収工程が完了した油分吸収剤に、水分保持剤を添加する（添加工程）。最後に、添加工程により得られた各成分の混合物を撹拌する（撹拌工程）。これにより、本発明のパウダー状害虫忌避組成物が完成する。 First, a pest repellent and an irritation reducing agent are mixed (mixing step). Next, the mixture obtained by the mixing step is absorbed by the oil absorbent (absorption step). Further, a water retention agent is added to the oil absorbent that has completed the absorption process (addition process). Finally, the mixture of each component obtained by the addition process is stirred (stirring process). Thereby, the powdery pest repellent composition of the present invention is completed.
ここで、パウダー状害虫忌避組成物の各成分の配合量について、本発明者らが試行錯誤を行ったところ、害虫忌避効果、及び人体や動物への安全性を確保しながら、使用感及び持続性に優れた製品とするためには、上記の各成分のうち、特に、水分保持剤の配合量と油分吸収剤の配合量とを適切な比率に設定することが重要であることが判明した。具体的には、水分保持剤の配合量（添加量）をａとし、油分吸収剤の配合量（使用量）をｂとすると、水分保持剤の配合量と油分吸収剤の配合量との比（ａ：ｂ）が、重量比で３：１〜２０：１となるように、好ましくは３：１〜１９：１となるように設定する。配合比が３：１より小さい場合、すなわち、水分保持剤の配合量が油分吸収剤の配合量よりも少な過ぎる場合、十分に水分を保持できなくなるため、粉落ちが発生する虞がある。配合比が２０：１より大きい場合、すなわち、水分保持剤の配合量が油分吸収剤の配合量よりも多過ぎる場合、しっとり感よりもべとつき感の方が強く感じられるようになり、使用感が悪化することがある。配合比を上記の適切な範囲に設定すれば、使用者がパウダー状害虫忌避組成物を皮膚に塗布すると、皮脂等の油分がケイ酸化合物に適度に吸収されつつ、タルクが適度に水分を保持することにより、べとつきを抑えながら、しっとりとした感触が得られる。また、タルク及びケイ酸化合物は安定した物質であるため、害虫忌避剤の効果を弱める虞がなく、刺激緩和剤の効果と相まって、低刺激でありながら忌避効果の高い製品となる。 Here, as for the amount of each component of the powdery pest repellent composition, the present inventors conducted trial and error, and while ensuring the pest repellent effect and safety to the human body and animals, the feeling of use and lasting In order to obtain a product with excellent properties, it has been found that it is particularly important to set an appropriate ratio between the amount of the water retaining agent and the amount of the oil absorbent, among the above components. . Specifically, when the blending amount (addition amount) of the moisture retention agent is a and the blending amount (use amount) of the oil absorbent is b, the ratio between the blending amount of the moisture retention agent and the blending amount of the oil absorption agent. (A: b) is set so that the weight ratio is 3: 1 to 20: 1, preferably 3: 1 to 19: 1. When the blending ratio is less than 3: 1, that is, when the blending amount of the moisture retaining agent is too small than the blending amount of the oil absorbent, moisture cannot be retained sufficiently, and there is a possibility that powder falling may occur. When the blending ratio is larger than 20: 1, that is, when the blending amount of the moisture retaining agent is too much than the blending amount of the oil absorbent, the sticky feeling is felt more strongly than the moist feeling, and the feeling of use is increased. May get worse. If the blending ratio is set within the above-mentioned range, when the user applies the powdery pest repellent composition to the skin, oil such as sebum is appropriately absorbed by the silicate compound, while talc retains moisture appropriately. By doing so, a moist feel can be obtained while suppressing stickiness. In addition, since talc and silicic acid compounds are stable substances, there is no possibility of weakening the effect of the pest repellent, and coupled with the effect of the stimulant mitigating agent, the product has a low irritant and high repellent effect.
