Description

人工毛と地毛との接着性を増大するための処理剤及び処理方法Treatment agent and treatment method for increasing adhesion between artificial hair and ground hair

　本発明は、還元剤を有効成分として含む、人工毛と地毛との接着性を増大するための処理剤及び処理方法に関する。 The present invention relates to a treating agent and a treating method for increasing the adhesion between artificial hair and ground hair containing a reducing agent as an active ingredient.

　現在、日本、アメリカ、ヨーロッパ等の世界各地で、女性の睫毛美容は一般的であり、マスカラやつけ睫毛が典型的に使用されている。つけ睫毛は、マスカラと比較して、海水浴や入浴時の水分や、運動時の汗等による剥落や剥離に対して持続性や耐性等の長所がある。 Currently, women's eyelash beauty is common throughout the world, such as Japan, the United States, Europe, etc., and mascara and false eyelashes are typically used. Compared to mascara, false eyelashes have advantages such as durability and resistance to peeling and peeling due to moisture during bathing and bathing, sweat during exercise, and the like.

　つけ睫毛は合成繊維から製造されることが典型的であり、さまざまな接着剤が、つけ睫毛を地毛に接着するために使用可能である。この接着剤には、ヒトの手術に用いられる安全でマイルドなタイプから、瞬間接着剤のように強力に接着するが、刺激が強いタイプまで、さまざまな種類が存在する。アロンアルファ（登録商標）に代表される瞬間接着剤は確かに良く接着する一方、使用時に有害事象を伴うおそれがある。 The false eyelashes are typically manufactured from synthetic fibers, and various adhesives can be used to adhere the false eyelashes to the ground hair. There are various types of adhesives, ranging from safe and mild types used in human surgery to strong adhesives such as instant adhesives, but strong types. Instant adhesives, such as Aron Alpha®, will adhere well, but may cause adverse events during use.

　また、地毛と人工毛との接着性を向上させるための準備剤が開示されている（特許文献１）。しかし、この準備剤は、ポリビニルピロリドン（ＰＶＰ）、ポリアクリレート、エタノール等を含み、眉毛の油分や水分、ほこり、塩分の除去するために使用される。 Also, a preparation for improving the adhesion between ground hair and artificial hair is disclosed (Patent Document 1). However, this preparatory agent contains polyvinylpyrrolidone (PVP), polyacrylate, ethanol, and the like, and is used to remove eyebrows oil, moisture, dust, and salt.

　従来、地毛と人工毛との接着性を増大させるための処理剤は知られていない。また、睫毛は、眉毛と比較して目により近くに存在するため、より高い安全性が睫毛の処理剤に求められる。そこで、安全性が高く、高い接着効果をもたらすことのできる人工毛と地毛との接着性を増大するための処理剤及び処理方法を開発する必要がある。 Conventionally, there is no known treatment agent for increasing the adhesion between ground hair and artificial hair. Further, since eyelashes are closer to the eyes than eyebrows, higher safety is required for the eyelash treatment agent. Therefore, it is necessary to develop a treatment agent and a treatment method for increasing the adhesion between artificial hair and ground hair, which is highly safe and can provide a high adhesion effect.

　本発明者らは、合成繊維製のつけ睫毛は、いかなる接着剤を用いてもお互いに強く接着するが、睫毛－睫毛、及び、睫毛－つけ睫毛の間では、接着性が非常に弱いことを見出した。この発見は、睫毛の表面を改変（処理）すれば、つけ睫毛を睫毛に強く接着し得ることを示す。そこで、本発明者らは、人工毛と地毛との接着性を増大するための、還元剤を有効成分として含む処理剤、及び、処理方法に関する本発明を完成した。 The present inventors have found that false eyelashes made of synthetic fibers strongly adhere to each other using any adhesive, but the adhesion between the eyelashes-lashes and the eyelashes-false eyelashes is very weak. I found it. This finding indicates that if the surface of the eyelashes is modified (treated), the false eyelashes can adhere strongly to the eyelashes. Accordingly, the present inventors have completed the present invention relating to a treatment agent containing a reducing agent as an active ingredient and a treatment method for increasing the adhesion between artificial hair and ground hair.

　接着力評価試験（１）
　材料及び方法
　人工毛として、ポリエステルポリマーの合成繊維（カタログ番号１１０４－０００５９６、株式会社ケイトオブ東京、直径０．１５ｍｍ）（以下、「ポリエステル繊維」という。）が用いられた。地毛として、健常人男性の毛髪（各５．０ｃｍ）が用いられた。 Adhesive strength evaluation test (1)
Materials and Methods A synthetic fiber (catalog number 1104-000596, Kate of Tokyo Co., Ltd., diameter 0.15 mm) (hereinafter referred to as “polyester fiber”) was used as the artificial hair. Healthy human hair (5.0 cm each) was used as the ground hair.

　処理剤での処理
　毛髪は、５％アンモニア水（和光純薬（株））でｐＨ８．５に調整した５％チオグリコール酸（和光純薬（株））の水溶液を処理剤として用いて７分間処理された（以下、「処理毛髪」という。）。対照として、毛髪は、前記混合液で処理されなかった（以下、「非処理毛髪」という。）。その後、処理毛髪及び非処理毛髪は流水下で１０分間洗浄され、ドライヤーで乾燥された。 Treatment with treatment agent Hair is treated with an aqueous solution of 5% thioglycolic acid (Wako Pure Chemical Industries, Ltd.) adjusted to pH 8.5 with 5% aqueous ammonia (Wako Pure Chemical Industries, Ltd.) for 7 minutes. Treated (hereinafter referred to as “treated hair”). As a control, hair was not treated with the mixed solution (hereinafter referred to as “untreated hair”). Thereafter, the treated hair and the untreated hair were washed for 10 minutes under running water and dried with a dryer.

　接着
　処理毛髪－ポリエステル繊維、及び、非処理毛髪－ポリエステル繊維が、それぞれ、シアノアクリレート系接着剤（ピグメンツグルー（商標）、カタログ番号１００２００１３２２、株式会社ケイトオブ東京）を用いて１．５ｃｍ接着された。一晩放置後に、接着力が評価された。 Adhesion Treated hair-polyester fiber and non-treated hair-polyester fiber were each adhered by 1.5 cm using a cyanoacrylate adhesive (Pigments Glue (trademark), catalog number 1002001322, Kate of Tokyo Co., Ltd.). . After standing overnight, the adhesion was evaluated.

　接着力評価
　処理毛髪－ポリエステル繊維、及び、非処理毛髪－ポリエステル繊維の接着力を評価するために、接着部位と反対側の末端部分は、それぞれ、画用紙（１．５ｃｍ×１．５ｃｍ）に接着剤（セメダイン（登録商標）、セメダイン株式会社）で接着された。画用紙は、それぞれ、接着面に対して垂直方向に引っ張られ、毛髪とポリエステル繊維とを剥離する際の応力が接着力として測定された。接着力は、引張試験機（ＡＧ－２５０ｋＮＩ、株式会社　島津製作所）で５ｍｍ／分の条件で測定された。接着力の測定値は剥離開始時から剥離完了時まで記録された。接着強度（Ｎ×ｍｍ）として、処理剤で処理されなかった場合の接着力の積算値（図１；斜線部分）と、処理剤で処理した場合の接着力の積算値（図２；斜線部分）とが画像解析ソフトを用いて算出された。接着力は、接着強度（Ｎ×ｍｍ）に基づいて比較された。 Adhesive strength evaluation In order to evaluate the adhesive strength of treated hair-polyester fibers and non-treated hair-polyester fibers, the end portion on the opposite side to the adhesion site is bonded to the drawing paper (1.5 cm x 1.5 cm). It was adhered with an agent (cemedine (registered trademark), Cemedine Co., Ltd.). Each drawing paper was pulled in a direction perpendicular to the bonding surface, and the stress at the time of peeling the hair and the polyester fiber was measured as an adhesive force. The adhesive force was measured with a tensile tester (AG-250 kNI, Shimadzu Corporation) at 5 mm / min. Adhesion measurements were recorded from the beginning of peeling until the completion of peeling. As the adhesive strength (N × mm), the integrated value of the adhesive force when not treated with the treating agent (FIG. 1; hatched portion) and the integrated value of the adhesive force when treated with the treating agent (FIG. 2; hatched portion) ) Was calculated using image analysis software. Adhesive strength was compared based on adhesive strength (N × mm).

　接着力評価試験（２）
　材料及び方法
　人工毛（ポリエステル繊維）として、つけ睫毛（カタログ番号１１０４－０００５９６、株式会社ケイトオブ東京、直径０．１５ｍｍ）が用いられた。地毛として、健常人男性の毛髪（各５．０ｃｍ）が用いられた。 Adhesive strength evaluation test (2)
Materials and Methods As artificial hair (polyester fiber), false eyelashes (catalog number 1104-000596, Kate of Tokyo Co., Ltd., diameter 0.15 mm) were used. Healthy human hair (5.0 cm each) was used as the ground hair.

　ブラッシング
　毛髪は歯科用回転鑢を用いてブラッシングされた。対照として、毛髪はブラッシングされなかった。 Brushing The hair was brushed using a dental rotary wrinkle. As a control, the hair was not brushed.

　処理剤での処理
　毛髪は、５％システインを含む処理剤（ｐＨ９）で７分間処理された後、流水下で１０分間洗浄され、ドライヤーで乾燥された。対照として、毛髪は処理剤で処理されなかった。 Treatment with treatment agent Hair was treated with a treatment agent (pH 9) containing 5% cysteine for 7 minutes, then washed under running water for 10 minutes, and dried with a drier. As a control, the hair was not treated with the treatment.

　接着
　ブラッシングされておらず、処理剤で処理されていない毛髪（ブラッシング－、処理剤－）、ブラッシングされた毛髪（ブラッシング＋）、処理剤で処理された毛髪（処理剤＋）、及び、ブラッシングされ、処理剤で処理された毛髪（ブラッシング＋、処理剤＋）は、それぞれ、シアノアクリレート系接着剤を用いてつけ睫毛と接着された。接着の条件は、室温で５分間であった。その後、接着力が評価された。 Adhesive hair that is not brushed and not treated with a treatment (brushing-, treatment-), brushed hair (brushing +), hair treated with a treatment (treatment agent +), and brushed The hair treated with the treatment agent (brushing +, treatment agent +) was adhered to the false eyelashes using a cyanoacrylate adhesive, respectively. The bonding condition was 5 minutes at room temperature. Thereafter, the adhesive strength was evaluated.

　接着力評価
　接着力を評価するために、接着部位と反対側の末端部分は、それぞれ、画用紙（１．５ｃｍ×１．５ｃｍ）に接着剤（セメダイン（登録商標）、セメダイン株式会社）で接着された。毛髪とつけ睫毛とを剥離する際の接着力は、自作のバネ秤で測定された。１００ｇ重が１ニュートン（Ｎ）として換算された。 Adhesive strength evaluation In order to evaluate the adhesive strength, the end portion on the opposite side to the adhesion site was respectively adhered to the drawing paper (1.5 cm × 1.5 cm) with an adhesive (Cemedine (registered trademark), Cemedine Co., Ltd.). It was. The adhesive force when peeling hair and false eyelashes was measured with a self-made spring balance. 100 g weight was converted as 1 Newton (N).

　結果
　図５は、毛髪と、つけ睫毛との接着力を示すグラフである。図５のグラフでは、縦軸は接着力（ニュートン（Ｎ））を示し、横軸は各実験条件を示す。各実験条件の誤差棒は同一条件で１０ないし２０回繰り返した実験結果の測定値の標準偏差を示す。接着力（Ｎ）は、毛髪（ブラッシング－、処理剤－）－つけ睫毛では０．１９Ｎであり、毛髪（処理剤＋）－つけ睫毛では０．３８Ｎであり、毛髪（ブラッシング＋）－つけ睫毛では０．４０Ｎであり、そして、毛髪（ブラッシング＋、処理剤＋）－つけ睫毛では０．９９Ｎであった。この結果から、毛髪とつけ睫毛との接着力は、毛髪をブラッシングするか、若しくは還元剤（システイン）を含む処理剤で毛髪を処理することによって統計学的に有意（ｐ＜０．００１、Ｓｔｕｄｅｎｔのｔ－検定）に増大することが明らかになった。また、毛髪とつけ睫毛との接着力は、毛髪をブラッシングし、還元剤（システイン）を含む処理剤で処理することによって統計学的に有意（ｐ＜０．００１、Ｓｔｕｄｅｎｔのｔ－検定）、かつ、相乗的に増大することが明らかになった。なお、システインを含む処理剤と同様に、他の還元剤（例えば、チオグリコール酸等）を含む処理剤も、接着力を相乗的に増大できることが示唆された。 Results FIG. 5 is a graph showing the adhesive strength between hair and false eyelashes. In the graph of FIG. 5, the vertical axis indicates the adhesive force (Newton (N)), and the horizontal axis indicates each experimental condition. The error bar for each experimental condition indicates the standard deviation of the measured value of the experimental result repeated 10 to 20 times under the same condition. Adhesive strength (N) is 0.19N for hair (brushing-, treatment agent-)-false eyelashes, and 0.38N for hair (treatment agent +)-false eyelashes, and hair (brushing +)-false eyelashes Was 0.40 N, and 0.99 N for hair (brushing +, treatment agent +)-pasted eyelashes. From this result, the adhesive force between the hair and false eyelashes is statistically significant (p <0.001, Student) by brushing the hair or treating the hair with a treatment containing a reducing agent (cysteine). T-test). In addition, the adhesive force between the hair and false eyelashes is statistically significant (p <0.001, Student's t-test) by brushing the hair and treating it with a treating agent containing a reducing agent (cysteine). And it became clear that it increases synergistically. In addition, it was suggested that the treatment agent containing other reducing agents (for example, thioglycolic acid etc.) can increase the adhesive force synergistically like the treatment agent containing cysteine.

　以上の実施例の結果から、地毛と人工毛との接着性は、地毛を処理剤で処理することによって顕著に増大することが明らかになった。また、地毛と人工毛との接着性は、地毛を処理剤で処理すること、及び、地毛をブラッシングすることを組み合わせることによって相乗的に増大できることが示された。 From the results of the above examples, it has been clarified that the adhesion between the natural hair and the artificial hair is remarkably increased by treating the natural hair with the treatment agent. Moreover, it was shown that the adhesiveness between the natural hair and the artificial hair can be increased synergistically by combining the treatment of the natural hair with the treatment agent and the brushing of the natural hair.
