Description

本発明は、抗菌防臭性に優れ、抗菌洗濯耐性に優れた獣毛使用の化粧用ブラシとその製造方法に関する。また、本発明は、第四アンモニウム塩を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、及びアルキルピリジニウム塩より選ばれたカチオン系界面活性剤を使用して、ハロー効果の優れ、抗菌防臭性及び洗濯耐性を有した獣毛の化粧用ブラシ及びその製造方法に関する。   The present invention relates to a cosmetic brush using animal hair that has excellent antibacterial and deodorant properties and excellent antibacterial washing resistance and a method for producing the same. In addition, the present invention uses a cationic surfactant selected from alkyl ammonium salts or alkyl benzyl ammonium salts including quaternary ammonium salts, and alkyl pyridinium salts, and has an excellent halo effect, antibacterial deodorization property and washing resistance. The present invention relates to a veterinary hair brush having hair and a method for producing the same.

最近では、社会や家庭における清潔志向の傾向を反映して、いわゆる抗菌用品に対する需要が高く、あらゆる商品に及んでいる。家庭用品のなかで、ブラシ類は抗菌機能への消費者の要求が強く、特に歯ブラシにおいては、口腔内で使用されるものであり、湿潤状態で保管されるものでもあるから、細菌が繁殖しやすく、このため従来から抗菌性歯ブラシについて数多くの技術が開示されている。代表的なものが、抗菌性を有する界面活性剤や殺菌剤などで処理した歯ブラシ類であり、例えば、トリクロロカルボアニリドなどの殺菌剤の溶剤溶液に親油性非イオン活性剤を少量含ませて処理した殺菌耐久性の歯ブラシ(特公昭48−27389号公報)、ハロゲン化サリチルアニリドやトリクロルカルバアニリドなどの殺菌剤を浸透せしめた自己殺菌性歯ブラシ(実公昭48−31719号公報、実公昭50−40688号公報)などがある。そして、歯ブラシ以外のヘアーブラシや化粧ブラシなどのブラシ類においても、フケや皮膚垢や皮脂などが残存付着しやすく、空気中の雑菌が繁殖して黴や悪臭が発生して不衛生な状態になりやすく、消費者の清潔志向と美的要求と相まって当然に抗菌ブラシへの要望が高いが、抗菌性や殺菌性などを有するものの公開技術は意外と少なく、例えば、イソプロピルメチルフェノールなどの抗菌剤溶液にスチレングリコールを添加して獣毛ブラシ類の抗菌性特性を付与するもの(特開昭53−128451号公報)、加圧雰囲気下にフェノール系抗菌剤溶液で処理して獣毛の内部まで抗菌剤を浸透させて抗菌性を高めたもの(特開平3−289905号公報)などが見られる程度である。   Recently, reflecting the trend toward cleanliness in society and households, so-called antibacterial products are in high demand, and have spread to all products. Among household goods, brushes have a strong consumer demand for antibacterial functions, and in particular, toothbrushes are used in the oral cavity and stored in a wet state, so that bacteria propagate. For this reason, many techniques for antibacterial toothbrushes have been disclosed. Typical examples are toothbrushes treated with antibacterial surfactants and bactericides such as trichlorocarbonanilide and other antibacterial solvent solutions containing a small amount of lipophilic nonionic active agents. Sterilized durable toothbrush (Japanese Patent Publication No. 48-27389), self-disinfecting toothbrush impregnated with a sanitizing agent such as halogenated salicylanilide or trichlorocarbanilide (Japanese Utility Model Publication No. 48-31719, Japanese Utility Model Publication No. 50-40688) Issue gazette). And in brushes such as hair brushes and makeup brushes other than toothbrushes, dandruff, skin plaque, and sebum are likely to remain, and bacteria in the air propagate to cause wrinkles and foul odors, resulting in an unsanitary state. Naturally, there is a high demand for antibacterial brushes in combination with consumers' desire for cleanliness and aesthetics, but there are surprisingly few published technologies that have antibacterial and bactericidal properties, such as antibacterial agent solutions such as isopropylmethylphenol. Styrene glycol is added to give antibacterial properties of animal hair brushes (Japanese Patent Laid-Open No. 53-128451). Antibacterial agents are treated with phenolic antibacterial solution in a pressurized atmosphere to the inside of animal hair In which antibacterial properties have been improved by permeating the water (JP-A-3-289905).

一方、ブラシ類のための抗菌剤の改良研究も進んでおり、抗菌機能やその持続性に優れた抗菌剤も使用されるようになり、分子内に第四級アンモニウム基を二個以上もつカチオン化剤にて獣毛をカチオン化し、両性又はアニオン性殺菌剤と反応させるもの(特開平2−274205号公報)、抗菌剤としてベンズイミダゾール系化合物とピリジン系化合物などとを併用するもの(特開平5−7510号公報)、殺菌剤としての第四級アンモニウム塩の利用を示唆するもの(登録実用新案公報3019605号:平成7年、登録実用新案公報3063570号:平成11年)などが開示されている。しかし、上述の従来技術では、抗菌剤による抗菌効果は処理の初期段階では優れた効果を発揮しても、抗菌性が不十分であり、雑菌や黴のためにブラシ本体や獣毛が黒ずんだり、悪臭を生じたりするのを完全には阻止できず、また、抗菌剤が徐々に脱落して抗菌性の持続性も経時的に長くはなく、これらの状況によって消費者を十分に満足させるには至っていない。一般に化粧用ブラシは、使用の度毎に使用済みの化粧料を除くために、使用後に必ず水洗いや手揉み洗濯がなされるが、このために、高い耐洗濯性が必要とされ、この性能を満たすために、従来では、バインダーを用い耐洗濯耐性を高めていたが、肌に粗剛な感触風合いとなり、消費者に受入れられなかった。   On the other hand, research on improving antibacterial agents for brushes is also progressing, and antibacterial agents with excellent antibacterial function and durability have come to be used, and cations having two or more quaternary ammonium groups in the molecule. Catalyzing animal hair with an agent and reacting it with an amphoteric or anionic fungicide (Japanese Patent Laid-Open No. 2-274205), a combination of a benzimidazole compound and a pyridine compound as an antibacterial agent No. 5-7510), which suggests the use of a quaternary ammonium salt as a disinfectant (Registered Utility Model Publication No. 3019605: 1995, Registered Utility Model Publication No. 3063570: 1999), etc. are disclosed. Yes. However, in the above-mentioned conventional technology, even if the antibacterial effect of the antibacterial agent is excellent in the initial stage of treatment, the antibacterial property is insufficient, and the brush body and animal hair are darkened due to various bacteria and wrinkles. , It can not completely prevent the generation of bad odors, and the antibacterial agent is gradually dropped and the antibacterial persistence is not long over time. Has not reached. In general, cosmetic brushes must be washed with water or hand-washed after use to remove used cosmetics every time they are used. In order to satisfy this requirement, conventionally, a binder was used to increase the washing resistance, but the skin feels rough and unsatisfactory.

上述の公知技術において、獣毛処理に多用されている方法は、獣毛を汎用の抗菌剤溶液に浸漬した後、脱液して乾燥して抗菌剤や殺菌剤を固定する方法であるが、この方法では特に化粧用ブラシにおいて、抗菌剤による獣毛の物性変化で毛先が硬くなり、化粧用ブラシの肌触りも良くなく、その上、化粧用ブラシへの化粧料の乗りが悪いなどの使用性の上での欠点があった。また、従来、一般的な第四級アンモニウム塩を使用しても、獣毛への抗菌剤の固着が十分ではなく、獣毛による獣毛臭が防止できないなどの問題が解消されず、含まれる抗菌性の洗濯による持続性、いわゆる抗菌洗濯耐性が高くはなく、抗菌力の指標であるハロー幅が不十分であった。   In the above-mentioned known technology, a method frequently used for animal hair treatment is a method of immersing animal hair in a general-purpose antibacterial agent solution, and then draining and drying to fix the antibacterial agent and disinfectant. In this method, especially in cosmetic brushes, the hair ends become stiff due to changes in the physical properties of animal hair due to antibacterial agents, and the cosmetic brush does not feel good. In addition, the use of cosmetics on the cosmetic brush is poor. There was a defect in the nature. In addition, even when a conventional quaternary ammonium salt is used, the antibacterial agent is not sufficiently fixed to animal hair, and problems such as animal hair odor due to animal hair cannot be prevented are included. Sustainability due to antibacterial washing, so-called antibacterial washing resistance was not high, and the halo width, which is an index of antibacterial activity, was insufficient.

本発明は、ブラシ類でも特に最近のファッション志向や美的要求の傾向により需要の高い化粧用ブラシにおいて、上述の諸問題を解決して、抗菌性に優れ、その抗菌性の持続性が経時的に長く、しかも獣毛臭がなく、防虫効果を有するから、従来のように防虫剤の必要がなく、さらに従来の抗菌加工による獣毛の物性変化によって毛先が硬くなることがなく、ブラシの肌触りが良く、しかもブラシへの化粧料の乗りが良好な化粧用ブラシを得ることを目的とするものである。そこで、本発明は、従来技術でも使用されている第四級アンモニウム塩の利用に着目して、獣毛への抗菌剤の固着をより一層十分なものとし、獣毛による獣毛臭を防止し、ハロー幅も十分で、且つ満足すべき抗菌洗濯耐性を有し、さらに虫の忌避効果によって防虫剤としての機能も発揮する化粧用ブラシを提供することを課題とする。   The present invention solves the above-mentioned problems in brushes, especially in cosmetic brushes that are in high demand due to the recent trend of fashion orientation and aesthetic demands. Because it is long and has no animal hair odor and has an insect repellent effect, there is no need for an insect repellent as in the past, and the tip of the hair does not become stiff due to changes in the physical properties of animal hair by conventional antibacterial processing, and the touch of the brush The object of the present invention is to obtain a cosmetic brush that is good and has a good cosmetic load on the brush. Therefore, the present invention pays attention to the use of the quaternary ammonium salt that is also used in the prior art, makes the antibacterial agent firmly fixed to animal hair, and prevents animal hair odor from animal hair. Another object of the present invention is to provide a cosmetic brush that has a sufficient width of halo, has satisfactory antibacterial washing resistance, and also exhibits a function as an insect repellent by an insect repellent effect.

本発明で使用するハロー幅は、抗菌用品において抗菌性の目安又は指標として、一般に知られているもので、寒天培養地にグラム陽性菌とグラム陰性菌を培養し、抗菌テストにおいて抗菌剤が平板寒天培養地中に拡散し、培養後に菌の増殖が阻止された、試験片の獣毛の周囲の領域の大きさを測定することにより、抗菌性を数値化する。ハロー幅は、一般にJIS−L−1902に準拠して測定され、以下の式で表示される。
W=(T−D)/2W:ハローの幅T:試験片とハローの長さの合計〔mm〕
D:試験片の長さ〔mm〕)。
The halo width used in the present invention is generally known as a measure or indicator of antibacterial properties in antibacterial products. Gram-positive and gram-negative bacteria are cultured in an agar culture medium, and the antibacterial agent is a flat plate in an antibacterial test. The antibacterial properties are quantified by measuring the size of the area around the animal hair of the test piece that has spread into the agar culture and has been inhibited from growing after the culture. The halo width is generally measured according to JIS-L-1902 and is expressed by the following equation.
W = (TD) / 2W: halo width T: total length of specimen and halo [mm]
D: Length of test piece [mm]).

本発明者らは、化粧用ブラシにおける上記課題を解決するために、鋭意検討し、化粧用ブラシの処理剤としてカチオン系界面活性剤としての、第四級アンモニウム塩の中で、特定の第四級アンモニウム塩を使用することによって、本発明を完成した。また、カチオン系界面活性剤の中で、アルキルピリジニウム塩が同様に抗菌作用又は殺菌作用を有することを見出した。すなわち、本発明者らは、抗菌性を持つ各種界面活性剤の中で、獣毛の蛋白質に対する親和性に注目し、第四級アンモニウム塩を中心に、抗菌性において優れた活性を示す多数の界面活性剤類を、獣毛に吸着や染着させ、その効果を対比検討した結果、獣毛の蛋白質に吸着して、洗濯しても脱落し難いカチオン系界面活性剤に着目し、第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩を用いた場合に、獣毛の抗菌性が極めて良好となることが判明したことにより、本発明に至った。本発明により、アンモニウム塩を含む温浴によって獣毛を処理することによって、獣毛の形態や外観又は肌触りをほとんど変えることなく、肌への感触が極めて良好で、ブラシへの化粧料の乗りも良好であって、しかも、抗菌性が非常に良好で、長期持続の抗菌性、すなわち殺菌洗濯耐性を持った獣毛化粧用ブラシを経済的に安価に提供することができる。また、本発明では上記第四級アンモニウム塩又はアルキルピリジニウム塩の利用によって、獣毛への抗菌剤の固着を十分とし、細菌による臭気の発生を防止できるとともに、従来最も困難とされていた獣毛による特有の獣毛臭を防止し、抗菌剤の洗濯耐性も高めることに成功した。   In order to solve the above-mentioned problems in cosmetic brushes, the present inventors have intensively studied, and among the quaternary ammonium salts as cationic surfactants as treatment agents for cosmetic brushes, a specific fourth one. The present invention was completed by using a quaternary ammonium salt. Moreover, it discovered that the alkyl pyridinium salt similarly has an antibacterial action or a bactericidal action among cationic surfactants. That is, among the various surfactants having antibacterial properties, the present inventors pay attention to the affinity for animal hair proteins, and mainly a quaternary ammonium salt, and exhibit a large number of antibacterial activities. As a result of adsorbing and dyeing surfactants on animal hair and comparing the effects, we focused on cationic surfactants that adsorb to animal hair proteins and are not easily removed even after washing. The use of alkylammonium salts or alkylbenzylammonium salts containing secondary nitrogen and further alkylpyridinium salts proved that the antibacterial properties of animal hair were extremely good, leading to the present invention. By treating the animal hair with a warm bath containing an ammonium salt according to the present invention, the feel to the skin is very good and the cosmetic is applied to the brush with almost no change in the form, appearance or feel of the animal hair. Moreover, it is possible to economically provide an animal hair cosmetic brush that has very good antibacterial properties and has long-lasting antibacterial properties, that is, bactericidal washing resistance. Further, in the present invention, the use of the quaternary ammonium salt or alkylpyridinium salt makes it possible to sufficiently fix the antibacterial agent to animal hair, prevent the generation of odor due to bacteria, and animal hair that has been considered the most difficult in the past. It has succeeded in preventing the peculiar animal hair odor caused by and increasing the washing resistance of antibacterial agents.

本発明においては、数多くの第四級アンモニウム塩を獣毛に吸着や染着させ、その効果を対比検討した結果、カチオン系界面活性剤、特に第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩が、獣毛の蛋白質への吸着性が高く、洗濯しても脱落し難くて抗菌性の持続性が良く、また、獣毛の形態や外観又は肌触りなどをほとんど変えることなく、肌への毛先の感触が極めて良好で、ブラシへの化粧料の乗りも良好であって、獣毛臭も防止でき、さらに虫の忌避効果があるので、従来使用されていた防虫剤としてナフタリン等の使用の必要がなくなる。また、本発明では、カチオン系界面活性剤のアルキルビリジニウム塩が上記第四級アンモニウム塩と同様の効果を奏することもわかった。さらに、本発明では、加熱液による抗菌剤の吸着や、後述のように吸着助剤や蛋白質変性剤の使用などの独特の工夫をこらしているものであることも特徴とするものである。   In the present invention, as a result of adsorbing and dyeing a large number of quaternary ammonium salts on animal hair, and comparing the effects thereof, cationic surfactants, particularly alkylammonium salts containing quaternary nitrogen or alkylbenzylammoniums were obtained. Salt is highly adsorbable to animal hair protein, it is hard to come off even after washing, has good antibacterial durability, and has almost no change in the form, appearance or feel of animal hair. Use of naphthalene as an insect repellent that has been used in the past because the hair feel is very good, the cosmetics are applied to the brush, and animal hair odor can be prevented. The need for is gone. In the present invention, it has also been found that the alkylbidinium salt of a cationic surfactant exhibits the same effect as the quaternary ammonium salt. Furthermore, the present invention is characterized by unique measures such as adsorption of an antibacterial agent by a heating liquid and use of an adsorption aid and a protein denaturant as described later.

すなわち本発明は、以下の通りのものである。That is, the present invention is as follows.
請求項1に係る化粧用ブラシは、獣毛からなる化粧ブラシであって、カチオン系界面活性剤が第四級窒素を含む、アルキルアンモニウム塩、アルキルベンジルアンモニウム塩又はアルキルピリジニウム塩であり、前記獣毛が、少なくとも一種又は二種以上の上記カチオン系界面活性剤の0.2〜5重量%を加熱液で吸着処理を行って固着しており、防臭性及び防虫性を有することを特徴とする。The cosmetic brush according to claim 1 is a cosmetic brush made of animal hair, wherein the cationic surfactant is an alkyl ammonium salt, an alkyl benzyl ammonium salt or an alkyl pyridinium salt containing quaternary nitrogen, The hair is fixed by subjecting 0.2 to 5% by weight of at least one or two or more of the above-mentioned cationic surfactants to an adsorption treatment with a heating liquid, and has deodorizing properties and insect repellent properties. .
請求項2に係る化粧用ブラシは、蛋白質変性剤及び/又は吸着助剤により前記カチオン系界面活性剤が固着されてなることを特徴とする。The cosmetic brush according to claim 2 is characterized in that the cationic surfactant is fixed by a protein denaturant and / or an adsorption aid.
請求項3に係る化粧用ブラシの防臭及び防虫方法は、獣毛からなる化粧ブラシの該獣毛に、防臭性及び防虫性を付与する化粧用ブラシの防臭及び防虫方法であって、カチオン系界面活性剤が第四級窒素を含む、アルキルアンモニウム塩、アルキルベンジルアンモニウム塩又はアルキルピリジニウム塩であり、上記カチオン系界面活性剤から少なくとも一種又は二種以上を選択し、その選択したカチオン系界面活性剤を含有する水溶液に、前記獣毛を浸漬し、加熱液で吸着処理を行って上記獣毛に上記カチオン系界面活性剤を0.2〜5重量%固着せしめることを特徴とする。The deodorizing and insect-repelling method for a cosmetic brush according to claim 3 is a deodorizing and insect-repelling method for a cosmetic brush that imparts deodorizing and insect-repelling properties to the animal hair of a cosmetic brush made of animal hair, comprising a cationic interface The active agent is an alkylammonium salt, alkylbenzylammonium salt or alkylpyridinium salt containing quaternary nitrogen, and at least one or more selected from the above cationic surfactants, and the selected cationic surfactant The animal hair is soaked in an aqueous solution containing water and subjected to an adsorption treatment with a heating solution to fix the cationic surfactant to 0.2 to 5% by weight on the animal hair.

本発明の化粧用ブラシを図面を用いて説明する。本発明の化粧用ブラシは、主として女性が顔や肌などに、ファンデーションやおしろいなどの各種の化粧料を塗るために使用され、図1に示すように、ブラシ台1にブラシとしての獣毛2が固定されている。一般にブラシ台はプラスチックや木材などから形成される。本発明で用いる、獣毛は、馬毛、豚毛、山羊毛又は狸毛など一般にブライ類に使用されているものであれば格別の制限はない。これらの獣毛は、ナイロン毛などの合成繊維のものに比して、肌触りも良く、保水性が良く、静電気も発生しないという特徴がある。   The cosmetic brush of the present invention will be described with reference to the drawings. The cosmetic brush according to the present invention is mainly used by women to apply various cosmetics such as foundations and funny to the face and skin, and as shown in FIG. Is fixed. In general, the brush base is made of plastic or wood. The animal hair used in the present invention is not particularly limited as long as it is generally used for bries such as horse hair, pig hair, goat hair, and eyelash hair. These animal hairs are characterized by a good touch, good water retention, and no generation of static electricity compared to synthetic fibers such as nylon hair.

本発明は、上述のとおり、特定のカチオン系界面活性剤、特に第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩を少なくとも一種又は二種以上を0.2〜5重量%加熱、吸着により固着させてなる獣毛を使用した手揉み洗濯耐性の抗菌防臭性を有する化粧用ブラシをうるものであるが、上記第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩は、従来から界面活性剤として多用されているもので、優れた抗菌性を発揮し、自体、防臭性をも有するものである。例えば、アルキルアンモニウム塩は、アルキルトリメチルアンモニウム塩やジアルキルジメチルアンモニウム塩であり、アルキルベンジルアンモニウム塩は、アルキルジメチルベンジルアンモニウム塩であり、アルキルピリジニウム塩は、ピリジン環にアルキル基が結合した塩であり、第四級窒素がプラスイオンを形成し、塩素や臭素などのハロゲン原子がマイナスイオンを形成する塩であって、(R3 N−R)+ - で表示される。 In the present invention, as described above, a specific cationic surfactant, particularly an alkylammonium salt or alkylbenzylammonium salt containing quaternary nitrogen, and further at least one alkylpyridinium salt in an amount of 0.2 to 5 is used. An alkylammonium salt or alkylbenzylammonium salt containing quaternary nitrogen as described above, which provides a cosmetic brush having antibacterial and deodorant resistance against hand-washing using animal hair that is fixed by heating and adsorption by weight%. Furthermore, alkylpyridinium salts have been widely used as surfactants in the past, exhibit excellent antibacterial properties, and have deodorizing properties themselves. For example, the alkyl ammonium salt is an alkyl trimethyl ammonium salt or a dialkyl dimethyl ammonium salt, the alkyl benzyl ammonium salt is an alkyl dimethyl benzyl ammonium salt, and the alkyl pyridinium salt is a salt in which an alkyl group is bonded to a pyridine ring, A salt in which quaternary nitrogen forms a positive ion and a halogen atom such as chlorine or bromine forms a negative ion, which is represented by (R 3 N—R) + X .

しかしながら、本発明では、上記カチオン系界面活性剤の中で、特に上記第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩を使用したときに格別の効果を奏することを基本とするものである。すなわち、本発明では、第四級アンモニウム塩を中心に、抗菌性において優れた活性を示す多数の界面活性剤類を、獣毛に吸着や染着させ、その効果を対比検討した結果、本発明の上記カチオン系界面活性剤が、獣毛の蛋白質への吸着性が高く、洗濯しても脱落し難くて抗菌性の持続性が良く、また、獣毛の形態や外観又は肌触りなどをほとんど変えることなく、肌への毛先の感触が極めて良好で、ブラシへの化粧料の乗りも良好であって、獣毛臭も防止できる。これらの化合物で処理した獣毛は、処理直後だけでなく、少しづつ上記第4級アンモニウム塩が滲出してくるので、長期に亘って化粧ブラシの抗菌防臭性を維持することが出来る。   However, in the present invention, among the above-mentioned cationic surfactants, particularly when an alkylammonium salt or alkylbenzylammonium salt containing the quaternary nitrogen, or an alkylpyridinium salt is used, a special effect is achieved. Basic. That is, in the present invention, a large number of surfactants exhibiting excellent activity in antibacterial properties, mainly quaternary ammonium salts, are adsorbed and dyed on animal hair, and as a result of comparing the effects thereof, the present invention The above cationic surfactant has a high adsorptive property to animal hair protein, and it is difficult to come off even after washing and has a long antibacterial property, and also almost changes the form, appearance or feel of animal hair. In addition, the feel of the hair tip to the skin is very good, the cosmetic is applied to the brush well, and animal hair odor can be prevented. In animal hair treated with these compounds, the quaternary ammonium salt exudes not only immediately after treatment but also gradually, so that the antibacterial and deodorizing properties of the cosmetic brush can be maintained over a long period of time.

本発明で使用される第四級アンモニウム塩の具体例は、(1)アルキルアンモニウム塩としては、塩化ドデシルトリメチルアンモニウム、塩化アルキルトリメチルアンモニウム、塩化ヘキサデシルトリメチルアンモニウム、塩化オクタデシルトリメチルアンモニウム、塩化ラウリルトリメチルアンモニウム、臭化ラウリルトリメチルアンモニウム、塩化ミリスチルトリメチルアンモニウム、塩化セチルトリメチルアンモニウム、臭化セチルトリメチルアンモニウム、塩化ステアリルトリメチルアンモニウム、臭化ステアリルトリメチルアンモニウム、塩化オレイルトリメチルアンモニウム、臭化オレイルトリメチルアンモニウムなどのアルキルトリメチル型のアンモニウム塩、塩化オクチルヘキシルジメチルアンモニウム、塩化ジデシルジメチルアンモニウム、塩化ジオクチルジメチルアンモニウムなどのジアルキルジメチル型のアンモニウム塩、(2)アルキルベンジルのアンモニウム塩としては、塩化ミリスチルジメチルベンジルアンモニウム、塩化ヤシアルキルジメチルベンジルアンモニウム、塩化テトラデシルジメチルベンジルアンモニウム、塩化オクタデシルジメチルベンジルアンモニウム、塩化セチルジメチルベンジルアンモニウム、塩化ステアリルジメチルベンジルアンモニウム、塩化オレイルジメチルベンジルアンモニウムなどである。また、アルキルピリジニウム塩としては、塩化ラウリルピリジニウム、塩化セチルピリジニウムなどがある。   Specific examples of the quaternary ammonium salt used in the present invention include: (1) Alkyl ammonium salts include dodecyl trimethyl ammonium chloride, alkyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride, octadecyl trimethyl ammonium chloride, and lauryl trimethyl ammonium chloride. Alkyltrimethyl type such as lauryl trimethyl ammonium bromide, myristyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, cetyl trimethyl ammonium bromide, stearyl trimethyl ammonium chloride, stearyl trimethyl ammonium bromide, oleyl trimethyl ammonium chloride, oleyl trimethyl ammonium bromide Ammonium salt, octylhexyl dimethyl ammonium chloride, didecyl dimethyl chloride Dialkyldimethyl ammonium salts such as ruammonium and dioctyldimethylammonium chloride; (2) ammonium salts of alkylbenzyl include myristyldimethylbenzylammonium chloride, cocoalkyldimethylbenzylammonium chloride, tetradecyldimethylbenzylammonium chloride, octadecyldimethyl chloride Benzylammonium chloride, cetyldimethylbenzylammonium chloride, stearyldimethylbenzylammonium chloride, oleyldimethylbenzylammonium chloride, and the like. Examples of the alkyl pyridinium salt include lauryl pyridinium chloride and cetyl pyridinium chloride.

本発明では、上記抗菌性カチオン系界面活性剤、特に第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩は少なくとも一種又は二種以上を適宜に組み合わせて使用されるが、基本的には一種だけで十分である。使用量は、獣毛に対して0.2〜5重量%の範囲が適当で、0.2重量%未満では、抗菌防臭性などの効果が不足し、5重量%を超えると、抗菌防臭性などの効果が飽和して経済的でない。また、本発明における抗菌剤の獣毛への固着の手段は、加熱液吸着により固着させる方法が適当である。加熱液の温度は、60〜80℃程度好ましくは70℃以上の加熱液を使用し、30分程度の処理をし、水洗乾燥すれば、獣毛の形態や外観又は肌触りなどをほとんど変えることなく、肌への毛先の感触を良好になしえて、獣毛臭も防止できる。なお、獣毛の洗浄又は染色工程に続いて、本処理を行うことが経済的である。本発明の化粧用ブラシは、使用の度毎に使用済みの化粧料を除くための水洗いや手揉み洗濯した場合は、十分な抗菌洗濯耐性を有している。   In the present invention, the antibacterial cationic surfactant, particularly an alkylammonium salt or alkylbenzylammonium salt containing quaternary nitrogen, and further an alkylpyridinium salt are used in an appropriate combination of at least one or two or more. Basically, just one kind is enough. The amount used is suitably in the range of 0.2 to 5% by weight with respect to the animal hair. If it is less than 0.2% by weight, the effect such as antibacterial and deodorant properties is insufficient. Such effects are saturated and not economical. In addition, as a means for fixing the antibacterial agent to animal hair in the present invention, a method of fixing by heating liquid adsorption is appropriate. The temperature of the heating liquid is about 60 to 80 ° C., preferably 70 ° C. or higher, treated for about 30 minutes, washed with water and dried, with almost no change in animal hair form, appearance or touch. The hair tip feels good against the skin and can prevent animal hair odor. It is economical to perform this treatment following the animal hair washing or dyeing step. The cosmetic brush of the present invention has sufficient antibacterial washing resistance when washed with water or hand-washed to remove used cosmetics every time it is used.

本発明の抗菌性は、上述するようにハロー幅 (細菌発育阻止幅)で表示されるが、ハロー幅は、抗菌用品において抗菌性の目安ないしは指標として、普通に使用されているものであって、寒天培養地にグラム陽性菌とグラム陰性菌を培養し、抗菌テストにおいて抗菌剤が平板寒天培養地中に拡散し、培養後に菌の増殖が阻止された、試験片の獣毛の周囲の領域の大きさを測定することにより、抗菌性を数値化したものであり、上述するようにJISの規定で測定される。本発明の抗菌処理した獣毛では、上述のハロー試験(JIS−L−1902準拠)において、少なくとも2mm以上のハロー幅が得られたが、この獣毛をJIS−L−1042に準拠した洗濯液中(石鹸水溶液5g/L)に40℃で30分間浸漬した後、100回揉み洗いをすることによってもハロー幅の減少は少ない。このことはカチオン系界面活性剤の抗菌剤が、蛋白質に吸着しているものはアニオン活性剤に結合して効力が失われることはないことを示していることが確認される。   The antibacterial property of the present invention is indicated by the halo width (bacterial growth inhibition width) as described above, and the halo width is commonly used as an antibacterial measure or index in antibacterial products. The area around the animal hair of the specimen where gram-positive and gram-negative bacteria were cultured in the agar culture area, and the antibacterial agent was diffused in the plate agar culture area in the antibacterial test, and the growth of the bacteria was inhibited after the culture. By measuring the size, the antibacterial properties are quantified and are measured according to JIS regulations as described above. In the antibacterial treated animal hair of the present invention, a halo width of at least 2 mm or more was obtained in the above halo test (conforming to JIS-L-1902), and this animal hair was washed in accordance with JIS-L-1042. There is little decrease in the halo width by dipping in medium (soap aqueous solution 5 g / L) for 30 minutes at 40 ° C. and then washing 100 times. This confirms that the cationic surfactant antibacterial agent does not lose its efficacy when it is adsorbed to the protein and binds to the anionic surfactant.

また、本発明では、第四級窒素を含むアルキルアンモニウム塩又はアルキルベンジルアンモニウム塩、さらにはアルキルピリジニウム塩より選ばれたカチオン系界面活性剤一種又は二種以上を含有する水溶液に、獣毛を浸漬し、加熱による吸着処理を行って獣毛にカチオン系界面活性剤を0.2〜5重量%固着せしめ、この獣毛を使用して化粧用ブラシとするものであるが、製造に際しては、抗菌剤の1〜3重量%程度の水溶液を60〜80℃程度、好ましくは70℃以上に加熱した加熱液を使用し、獣毛に30分程度の浸漬処理をして水洗乾燥する。このとき、蛋白質変性剤及び/又は吸着助剤の使用により、上記カチオン系界面活性剤の獣毛への吸着固定効果が高められるのである。上記蛋白質変性剤は、尿素や塩酸グアニジンなどを用いる。また、吸着助剤としては、無機酸や有機酸又は無機塩が使用され、無機酸は塩酸、硫酸、燐酸などであり、有機酸は酢酸、乳酸、リンゴ酸、クエン酸などであって、無機塩は硫酸ソーダ、塩化ナトリウムなどである。   Further, in the present invention, animal hair is immersed in an aqueous solution containing one or more cationic surfactants selected from alkyl ammonium salts or alkyl benzyl ammonium salts containing quaternary nitrogen, and further alkyl pyridinium salts. Then, an adsorption treatment by heating is carried out to fix 0.2 to 5% by weight of a cationic surfactant on animal hair, and this animal hair is used as a cosmetic brush. Using a heating solution in which an aqueous solution of about 1 to 3% by weight of the agent is heated to about 60 to 80 ° C., preferably 70 ° C. or higher, the animal hair is immersed for about 30 minutes and then washed with water and dried. At this time, the use of a protein denaturant and / or an adsorbent aid enhances the effect of adsorbing and fixing the cationic surfactant to animal hair. As the protein denaturing agent, urea, guanidine hydrochloride or the like is used. Further, as the adsorption aid, an inorganic acid, an organic acid or an inorganic salt is used, the inorganic acid is hydrochloric acid, sulfuric acid, phosphoric acid, etc., and the organic acid is acetic acid, lactic acid, malic acid, citric acid, etc. Examples of the salt include sodium sulfate and sodium chloride.

本発明の獣毛を使用した化粧ブラシにおいては、抗菌性に非常に優れその持続性と洗濯耐性も極めて良好で、また、獣毛を抗菌剤で表面処理したときに、抗菌剤の影響で毛先が硬くなることがなく、化粧ブラシの肌触りも良く、化粧ブラシへの化粧料の乗りも優れている上に、獣毛の防臭性も非常に良好である。さらに虫が食べなくなるので防虫効果が得られ、従来使用されていた防虫剤としてナフタリン等の使用の必要がなくなる。また、製造コストも安価である。   The cosmetic brush using the animal hair of the present invention has excellent antibacterial properties and has excellent durability and washing resistance. Also, when the animal hair is surface-treated with an antibacterial agent, the hair is affected by the antibacterial agent. The tip does not become hard, the touch of the makeup brush is good, the cosmetics are applied on the makeup brush, and the deodorizing property of animal hair is very good. Furthermore, since insects can no longer be eaten, an insect repellent effect is obtained, and the use of naphthalene or the like as a conventionally used insect repellent is eliminated. Also, the manufacturing cost is low.

次に、実施例に基づいて、図面及び比較例を参照しながら、本発明の実施の態様を具体的に説明するが、本発明はこれらに限定されるものではない。
(1)比較試験(本発明の第四級アンモニウム塩と他の第四級アンモニウム塩との比較)
本発明において、各種のカチオン系界面活性剤の抗菌性を対比するため、アルキルトリメチルアンモニウムクロライドのようなトリメチル型のアンモニウム塩、ミリスチルジメチルベンジルアンモニウムクロライドのようなアルキルジメチルベンジル型のアンモニウム塩、オクチルヘキシルジメチルアンモニウムクロライドのようなジアルキルジメチル型のアンモニウム塩、ラウリルピリジニウムクロライドのようなアルキルピリジニウム塩、アルキルベンザルコニウム塩、アルキルキノリニウム塩、ベンゼトニウムクロライド、2−メルカプトベンツチアゾール塩、ピリチオン酸やその塩、ピリチオン酸ダイマー、アルキルバラベン、ピロールニトリン、チアベンダゾール、イソチアゾリン、ブチルチンマレエートなどを温湯中に溶解させ、酸やボウ硝を添加して一定時間浸漬させて、抗菌剤を獣毛に吸着又は染着させ、水洗乾燥して、抗菌処理を行った。これらの化合物で処理した獣毛は、前述のハロー試験では、少なくとも2mm以上のハロー幅を得られるものが多かった。次いでこれらの獣毛を洗濯液中に40℃で、30分間浸漬した後、100回揉み洗いして、同じくハロー試験を行ったところ、本発明で使用する第4級アンモニウム塩では、良好なハロー幅を維持しているのに対して、これ以外の第4級アンモニウム塩では、ハロー幅の減少が大きく、しかも毛先の変化も大きく、化粧ブラシとしての使い勝手が悪いものであった。
Next, embodiments of the present invention will be specifically described based on examples with reference to the drawings and comparative examples, but the present invention is not limited to these.
(1) Comparative test (comparison between the quaternary ammonium salt of the present invention and other quaternary ammonium salts)
In the present invention, in order to compare the antibacterial properties of various cationic surfactants, trimethyl ammonium salt such as alkyltrimethylammonium chloride, alkyldimethylbenzyl ammonium salt such as myristyldimethylbenzylammonium chloride, octylhexyl Dialkyldimethyl-type ammonium salts such as dimethylammonium chloride, alkylpyridinium salts such as laurylpyridinium chloride, alkylbenzalkonium salts, alkylquinolinium salts, benzethonium chloride, 2-mercaptobenzthiazole salts, pyrithionic acid and its salts , Pyrithionate dimer, alkylbaraben, pyrrolnitrin, thiabendazole, isothiazoline, butyltin maleate, etc. dissolved in hot water By immersing a predetermined time by adding an acid and Glauber's salt, it is adsorbed or dyed antimicrobial agents in animal hair, washed with water dried and subjected to antibacterial treatment. Many animal hairs treated with these compounds were able to obtain a halo width of at least 2 mm in the halo test described above. Next, after immersing these animal hairs in a washing solution at 40 ° C. for 30 minutes, washing them 100 times and carrying out the same halo test, the quaternary ammonium salt used in the present invention has a good halo. While the width was maintained, the quaternary ammonium salts other than these had a large reduction in halo width and a large change in the tip of the hair, which was unusable as a makeup brush.

(2)ハロー幅の観察
本発明の化粧用ブラシの抗菌状態の変化を図面で見てみる。
