Description

ケラチン繊維の修復方法Method of repairing keratin fiber
　本発明は、毛髪や羊毛等のケラチン繊維の修復方法、ケラチン繊維修復剤、およびアイの水溶性成分の使用に関するものである。 The present invention relates to a method of repairing keratin fibers such as hair and wool, to keratin fiber repair agents, and to the use of water-soluble components of the eye.
　毛髪や羊毛等のケラチン繊維は、大部分がタンパク質のケラチンからなり、コルテックスやメデュラと呼ばれる内部の皮質や紡錘状の細胞と、外部を覆うキューティクルとから構成される。キューティクルは、無色透明な鱗状の形態を有し、重なりあって繊維の外周を保護している。 Keratin fibers such as hair and wool are mostly composed of protein keratin and are composed of inner cortex and spindle-like cells called cortex and medura and cuticles covering the outside. The cuticle has a colorless, transparent, bowl-like form, overlapping to protect the outer periphery of the fiber.
　ところで、毛髪には、染色、漂白、パーマネントウエーブなどの各種化学処理を施すことがあり、このような化学処理を反復して施すと表面のキューティクルが剥がれ、場合によっては内部にまで損傷を受ける。そうなると、毛髪から潤いが喪失し、切れ毛、枝毛、裂け毛が生じることになる。その一方で、毛髪は細胞が角質化して生じたものであり、謂わば死んでいる組織であるので、一度剥がれたキューティクルは同じ場所からは再生することはなく、受けた損傷は改善しえない。 By the way, the hair may be subjected to various chemical treatments such as dyeing, bleaching, permanent waves, etc. When such chemical treatments are repeated, the surface cuticle is peeled off, and in some cases, the inside is damaged. When this happens, moisture is lost from the hair and cuts, splits and tears will occur. On the other hand, since hair is a keratinized cell and so-called dead tissue, cuticles that have been peeled off can not be regenerated from the same place, and the damage received can not be improved. .
　また羊毛からなる衣服等の織編物についても、長年着用すると擦れなど外部からの物理的作用により表面のキューティクルは損傷を受けることがある。 In addition, even with a woven or knitted fabric such as a garment made of wool, the surface cuticle may be damaged due to an external physical action such as rubbing when worn for many years.
　これまでに毛髪の化学処理による損傷を防止する手段として、セラミドおよびグリコセラミドから選ばれた少なくとも１つの化合物、少なくとも１つのカチオン系ポリマーおよび少なくとも１つの両性ポリマーを含むケラチン繊維保護用組成物を、化学処理に先立ち毛髪に適用することにより、化学処理による損傷から毛髪を保護する方法が提案されている（特許文献１）。 A composition for protecting keratin fibers comprising at least one compound selected from ceramides and glycoceramides, at least one cationic polymer and at least one amphoteric polymer as means for preventing damage caused by chemical treatment of hair so far. A method has been proposed to protect the hair from damage due to chemical treatment by applying it to the hair prior to the chemical treatment (US Pat. No. 5,677,859).
特開２００２－１２８６４３号公報JP 2002-128643 A
　しかしながら、上記特許文献１に記載の方法は、化学処理を施す前に所定の組成物を適用しておくものであり、化学処理などにより一旦損傷を受けてしまったケラチン繊維を修復、改善できるものではない。 However, the method described in Patent Document 1 applies a predetermined composition before chemical treatment, and can repair and improve keratin fibers that have been damaged once by chemical treatment or the like. is not.
　本発明は上記の様な事情に着目してなされたものであって、その目的は、損傷を受けたケラチン繊維を修復する方法、ケラチン繊維修復剤、およびアイの水溶性成分の使用を提供することにある。 The present invention was made in view of the above circumstances, and its object is to provide a method for repairing damaged keratin fibers, a keratin fiber repair agent, and the use of a water-soluble component of the eye. It is.
　本発明者は、前記課題を解決するために鋭意研究を重ねた結果、古くから染料等の原料として用いられている植物のアイから得られる水溶性成分が損傷を受けたケラチン繊維の表面を修復する作用を有することを見出し、本発明を完成した。 As a result of intensive studies to solve the above problems, the present inventor has repaired the surface of damaged keratin fiber from which the water-soluble component obtained from the eye of plants has long been used as a raw material for dyes and the like. It has been found that the present invention has the following effects.
　すなわち、本発明にかかるケラチン繊維の修復方法は、アイの水溶性成分をケラチン繊維の表面に付着させることを特徴とする。 That is, the method for repairing keratin fibers according to the present invention is characterized in that the water-soluble component of the eye is attached to the surface of the keratin fibers.
　本発明のケラチン繊維の修復方法においては、前記アイの水溶性成分の溶液をケラチン繊維の表面に付着させることが好ましい。このように溶液の形態でアイの水溶性成分を付着させると、本発明の修復効果をより実感しやすい。 In the method of repairing keratinous fibers according to the present invention, it is preferable to attach a solution of the water-soluble component of the eye to the surface of keratinous fibers. Thus, when the water-soluble component of the eye is attached in the form of a solution, the repair effect of the present invention is more easily realized.
　本発明のケラチン繊維の修復方法において、前記アイはタデ科タデ属のアイ（学名：Ｐｏｌｙｇｏｎｕｍ ｔｉｎｃｔｏｒｉｕｍ Ｌｏｕｒ）であることが好ましい。これにより、本発明の修復効果をより確実に発現させることができる。 In the method of repairing keratinous fibers according to the present invention, the eye is preferably an eye of the genus Tadeaceae (Scientific name: Polygonum tinctorium Lour). This makes it possible to more reliably express the repair effect of the present invention.
　本発明のケラチン繊維の修復方法においては、前記水溶性成分が前記アイの茎部から得られものであることが好ましい。アイは染料原料としては通常葉部のみが用いられ、茎部や根部は廃棄されているので、アイの水溶性成分がアイの茎部から得られるものであると、廃棄物を原料として利用できる。しかも、茎部から得られたアイの水溶性成分は本発明の修復効果をより確実に発現する。 In the keratin fiber repair method of the present invention, it is preferable that the water-soluble component be obtained from the stem of the eye. Since only the leaf part is used as the dye material and only the stem part and the root part are discarded, the waste can be used as a raw material if the water-soluble component of the eye is obtained from the stem part of the eye. .

　得られた抽出液のうち１０ｇを９０℃で加熱して乾固させ、その質量を測定することにより抽出液の固形分濃度を算出したところ、上記タデアイ抽出液の濃度は０．５質量％であった。このタデアイ抽出液に精製水を加えて５００倍に希釈し、下記の実施例で用いるタデアイ水溶性成分スプレー液とした。 10 g of the obtained extract was heated at 90 ° C. to dryness, and the solid content concentration of the extract was calculated by measuring its mass, and the concentration of the above-mentioned Tadeai extract was 0.5 mass%. there were. Purified water was added to the Tadeai extract, and the resulting solution was diluted 500 times to obtain a Tadeai water-soluble component spray solution used in the following examples.
　実施例１　毛髪の修復
　毛染めをしている３０歳代男性の毛髪を市販のシャンプーで洗髪した後、ドライヤーで乾燥させ、頭頂部あたりの毛髪を根元から切断し、処理前の毛髪の状態を観察した。観察は、切断した毛髪の中央部について、（Ａ）低真空型走査型電子顕微鏡（Ｎｉｃｏｎ社製「ε－ＳＥＭ－２７００」）と、（Ｂ）デジタルマイクロスコープ（ＨｉＲＯＸ社製「ＫＨ７７００」）を用いて行った。（Ａ）による拡大写真（１０００倍）を図１に、（Ｂ）による拡大写真（１４００倍）を図３に、それぞれ示す。 Example 1 Hair Repair Hair-dyed 30's male hair is washed with a commercial shampoo and then dried with a drier, and the hair per head is cut from the root and the condition of the hair before treatment is determined. I observed it. Observations were made of (A) low vacuum scanning electron microscope (“ε-SEM-2700” manufactured by Nicon) and (B) digital microscope (“KH7700” manufactured by HiROX) for the central part of the cut hair. It did. The enlarged photograph (1000 times) by (A) is shown in FIG. 1, and the enlarged photograph (1400 times) by (B) is shown in FIG. 3, respectively.
　次いで、製造例１で調製したスプレー液を電動式の霧吹き器に詰め、該スプレー液約５～３０ｍＬを洗髪、乾燥後の毛髪全体に満遍なく噴霧し、その後、ドライヤーで乾燥させ、頭頂部あたりの毛髪を根元から切断し、処理後の毛髪の状態を観察した。観察は、上記と同様、切断した毛髪の中央部について、（Ａ）低真空型走査型電子顕微鏡と、（Ｂ）デジタルマイクロスコープを用いて行った。（Ａ）による拡大写真（１０００倍）を図２に、（Ｂ）による拡大写真（１４００倍）を図４に、それぞれ示す。 Next, the spray solution prepared in Preparation Example 1 is packed in a motorized sprayer, and about 5 to 30 mL of the spray solution is washed evenly, sprayed evenly over the hair after drying, and then dried by a drier, per head The hair was cut from the root and the condition of the hair after treatment was observed. The observation was performed using the (A) low vacuum type scanning electron microscope and (B) digital microscope on the central part of the cut hair as described above. The enlarged photograph (1000 times) according to (A) is shown in FIG. 2, and the enlarged photograph (1400 times) according to (B) is shown in FIG.
　図１および図３のとおり、毛染めした処理前の毛髪は表面の毛表皮であるキューティクルがささくれ立ち、荒れていることが分かる。しかし、図２および図４のとおり、本発明に係るタデアイ水溶性成分を噴霧して付着させると、毛髪表面のささくれ立ちは抑制されて滑らかな表面になり、キューティクルの一つ一つが丸みを帯びて保護されていることが分かる。 As shown in FIG. 1 and FIG. 3, it can be seen that the hair dyed hair before treatment is rough and rough with the cuticle which is the surface skin. However, as shown in FIG. 2 and FIG. 4, when the water-soluble component of Thadeay according to the present invention is sprayed and attached, the burrs on the hair surface are suppressed and it becomes a smooth surface, and each cuticle becomes rounded. To be protected.
　毛髪の構成成分の大部分はタンパク質のケラチンであり、毛根細胞で生合成された後に毛髪内部から修復はされない。したがって、上記の結果は、本発明に係るタデアイ水溶性成分が毛髪表面のタンパク質に結合し、キューティクルを修復したことによるものであると考えられる。 Most of the components of the hair are protein keratins and are not repaired from the inside of the hair after being biosynthesized in hair root cells. Therefore, it is considered that the above result is due to that the water-soluble component of Tadeai according to the present invention is bound to the protein on the hair surface and the cuticle is repaired.
　実施例２　羊毛の修復
　製造例１で調製したスプレー液を電動式の霧吹き器に詰め、該スプレー液を、約４０年間保管した市販の羊毛１００％セーター（Ｃ－ＢＥＡＴ社製）の表面に満遍なく噴霧した後、一昼夜放置して自然乾燥させた。このとき噴霧量は、約１５ｃｍ2当たり約１～３ｍＬとした。このセーターのスプレー液を噴霧した部分から羊毛を４本抜き出し、デジタルマイクロスコープ（ＨｉＲＯＸ社製「ＫＨ７７００」）を用いて観察した。得られた拡大写真（１４００倍）を図５～図８にそれぞれ示す。なお、この試験に供したセーターは、年に１回程度着用し、その都度、洗濯して保管していたものである。 Example 2 Repair of Wool The spray solution prepared in Preparation Example 1 is packed in an electric sprayer, and the spray solution is evenly distributed on the surface of a commercially available 100% woolen sweater (C-BEAT) stored for about 40 years. After spraying, it was left to stand overnight and allowed to dry naturally. At this time, the spray amount was about 1 to 3 mL per about 15 cm 2 . Four wools were extracted from the part sprayed with the spray solution of this sweater, and observed using a digital microscope ("KH 7700" manufactured by HiROX). The resulting magnified photographs (1400 ×) are shown in FIGS. 5 to 8, respectively. In addition, the sweater used for this test was worn about once a year, and was washed and stored each time.
　約４０年間保管したセーターを構成する羊毛は、長年にわたる摩擦等によって、染色した毛髪のように、繊維表面のささくれ立ちなどの損傷を受けていると考えられるが、本発明に係るタデアイ水溶性成分を噴霧して付着させると、図５～８のとおり、繊維１本１本の表面が滑らかになり、ささくれ立ち等の損傷は認められなかった。 The wool that makes up the sweater, which has been stored for about 40 years, is considered to be damaged such as scraping of the fiber surface like dyed hair due to friction and the like for many years. As a result, as shown in FIGS. 5-8, the surface of each fiber becomes smooth, and no damage such as creaking is observed.
　羊毛の構成成分は毛髪と同様にタンパク質であることから、上記の結果は、本発明に係るタデアイ水溶性成分が羊毛表面のタンパク質に結合して修復したことによるものであると考えられる。 Since the component of wool is a protein like hair, the above-mentioned result is considered to be due to the fact that the water-soluble component of Tadeai according to the present invention is bound to the protein on the surface of wool and repaired.
