本発明は、美白髪剤に関する。より詳細には、本発明は、黄ばんだ白髪を色補正することで白髪の外観を美しくするために用いられる、美白髪剤に関する。 The present invention relates to a whitening hair agent. More specifically, the present invention relates to a whitening agent used to beautify the appearance of gray hair by color-correcting yellowed gray hair.
白髪は、毛母に色素細胞が供給されなくなることに発症する（非特許文献１）。白髪は老化の象徴となるため、古来より、白髪を隠す目的で黒や茶色に染める毛染めが使われてきた。 White hair develops when pigment cells are no longer supplied to the hair matrix (Non-Patent Document 1). Since gray hair is a symbol of aging, hair dyeing that dyes black or brown has been used since ancient times for the purpose of hiding gray hair.
一方で、近年、白髪を染めることなく、その自然な色調をグレイヘアと呼ぶ新たな風潮が高まっている。しかしながら、グレイヘアは、髪の色素が完全に抜け落ちた白髪になることにより完成されるものであるところ、白髪の移行期においては、色素の退去が不完全であることにより白髪が黄ばんで見えることがある。これは、ヒトの髪に存在する黒色のユーメラニンと黄色のフェオメラニン（非特許文献２）のうち、ユーメラニンが退去しフェオメラニンが残ることにより生じる。 On the other hand, in recent years, there has been a growing new trend of calling the natural color tone of gray hair without dyeing gray hair. However, gray hair is completed by completely removing the pigment from the hair, and in the transitional period of the gray hair, the gray hair may appear yellow due to incomplete removal of the pigment. be. This is caused by the elimination of eumelanin and the remaining pheomelanin among the black eumelanin and the yellow pheomelanin (Non-Patent Document 2) present in human hair.
黄ばんだ白髪はしばしば汚い印象をもたらすため、我慢できずに黒や茶色に染毛することが多く、グレイヘアの形成をあきらめざるを得ない。しかしながら、美しいグレイヘアを求める声は後を絶たない。 Yellowish gray hair often gives a dirty impression, so it is often unbearable and dyed black or brown, forcing the formation of gray hair to be abandoned. However, there is no end to the demand for beautiful gray hair.
そこで、本発明は、黄ばんだ白髪を濃色に染めることなく、その外観を美しくできる美白髪剤を提供することを目的とする。 Therefore, an object of the present invention is to provide a whitening agent that can make the appearance of yellowish gray hair beautiful without dyeing it in a dark color.
本発明者は鋭意検討した結果、紫色を呈する水溶性化合物を用いることで、黄ばんだ白髪を容易に色補正し、白髪の外観を美しくできることを見出した。本発明は、この知見に基づいてさらに検討を重ねることにより完成したものである。 As a result of diligent studies, the present inventor has found that by using a water-soluble compound exhibiting purple color, yellowed gray hair can be easily color-corrected and the appearance of gray hair can be made beautiful.

Especially preferable.
本発明の美白髪剤における紫色を呈する水溶性化合物の含有量としては、製剤形態によって異なりうるため特に限定されないが、総量で、例えば０．００５〜５重量％、好ましくは０．０１〜１重量％が挙げられる。 The content of the water-soluble compound exhibiting purple color in the whitening hair agent of the present invention is not particularly limited because it may vary depending on the formulation form, but the total amount is, for example, 0.005 to 5% by weight, preferably 0.01 to 1% by weight. % Can be mentioned.
本発明の色素化合物において、水溶性化合物は主色素として含まれる。水溶性化合物を主色素として含むとは、本発明の美白髪剤に含まれる色素化合物が、紫色を呈する水溶性化合物のみであってもよく、また他の１以上の色素化合物を含んでいてもよいが、他の１以上の色素化合物の含有量が、総量で、紫色を呈する水溶性化合物の重量％濃度よりも少なく、且つ、すべての色素化合物の混合物が、５００〜５９０ｎｍ、好ましくは５６０〜５９０ｎｍの波長を吸収する紫の色味であることをいう。本発明の効果をより一層好ましく得る観点からは、本発明の美白髪剤に含まれる色素化合物が、紫色を呈する水溶性化合物のみであることが好ましい。 In the dye compound of the present invention, the water-soluble compound is included as the main dye. The term "containing a water-soluble compound as a main dye" means that the pigment compound contained in the whitening agent of the present invention may be only a water-soluble compound exhibiting purple color, or may contain one or more other dye compounds. It is good, but the content of the other one or more dye compounds is less than the weight% concentration of the water-soluble compound which exhibits purple color in total, and the mixture of all the dye compounds is 500 to 590 nm, preferably 560 to 560 nm. It means that it has a purple tint that absorbs a wavelength of 590 nm. From the viewpoint of further favoring the effects of the present invention, it is preferable that the pigment compound contained in the whitening hair agent of the present invention is only a water-soluble compound exhibiting purple color.
本発明の美白髪剤は、上記成分の他、染毛用組成物の配合成分として一般に用いられる、油溶性色素化合物（好ましくは、紫色２０１号）、水性基剤、界面活性剤、油脂類、保湿剤、帯電防止剤、パール光沢付与剤、増粘剤、キレート剤、防腐剤、抗炎症剤、エキス類、酸化防止剤、溶剤、紫外線吸収剤、香料、ｐＨ調整剤、安定剤等を適宜配合することができる。 In addition to the above components, the whitening hair agent of the present invention contains oil-soluble pigment compounds (preferably purple No. 201), aqueous bases, surfactants, oils and fats, which are generally used as compounding components of hair dyeing compositions. Moisturizers, antistatic agents, pearl gloss enhancers, thickeners, chelating agents, preservatives, anti-inflammatory agents, extracts, antioxidants, solvents, UV absorbers, fragrances, pH adjusters, stabilizers, etc. Can be blended.
本発明において、美白髪剤とは、黄ばんだ白髪を色補正することによって、白髪の外観を美しくする染毛用組成物をいう。本発明の美白髪剤は、黄ばんだ白髪を色補正するために用いられる。本発明において色補正とは、グレーの白髪に色補正することを言い、色補正により呈されるグレーの具体的な色調としては、PANTONE Warm Gray1C-5C、PANTONE Cool Gray 1C-5C、PANTONE 400C-403C、PANTONE 406C-408C、PANTONE 413C-415C、PANTONE 420C-423C、PANTONE 427C-429C、PANTONE 7527C-7530C、PANTONE 7534C-7539Cが挙げられる。黄ばんだ白髪は、黒髪から白髪の移行期において、色素の退去が不完全でフェオメラニンが残ることで白髪が黄色みを帯びているが、紫色を呈する水溶性化合物で染色されることで、黄色みが無彩色化され、グレーの白髪とすることができる。このような色補正によって、黄色みが取れたグレイヘアを形成することができるため、白髪の外観を美しくすることができる。 In the present invention, the whitening agent refers to a hair dyeing composition that makes the appearance of white hair beautiful by color-correcting the yellowed white hair.

Yellowish gray hair is yellowish due to incomplete pigment removal and pheomelanin remaining during the transition period from black hair to gray hair, but it is yellow because it is dyed with a water-soluble compound that exhibits purple color. Only the hair is achromatic and can be gray gray hair. By such color correction, it is possible to form gray hair with a yellowish tint, so that the appearance of gray hair can be made beautiful.
本発明の美白髪剤の剤型としては、染毛用組成物に用いられる剤形であれば特に限定されず、例えば、液状、乳液状、クリーム状、ゲル状、泡沫状等が挙げられる。 The dosage form of the whitening agent of the present invention is not particularly limited as long as it is the dosage form used in the hair dyeing composition, and examples thereof include liquid, milky liquid, creamy, gelled, and foamy.
本発明の美白髪剤の具体的な形態としては、白髪に対する染毛用組成物の用途であれば特に限定されず、例えば、医薬部外品の永久染毛剤（白髪染め）、化粧品の半永久染毛料（白髪用ヘアマニキュア、白髪用カラーシャンプー、白髪用カラーリンス、白髪用カラートリートメント）等が挙げられる。 The specific form of the whitening agent of the present invention is not particularly limited as long as it is used as a hair dyeing composition for gray hair.

Then, the gray hair bundle was rinsed with water for 2 minutes and completely dried with a dryer. The steps of dyeing, rinsing and drying were repeated 10 times. After that, the color tone of the gray hair bundle was evaluated by a trained panelist based on the following criteria. The results are shown in Table 1.

○：パントーンカラー７５２７Ｃ（グレー）より薄い色調であるが黄色の印象はほとんど感じられない。
△：パントーンカラー７５０１Ｃ（黄色）とは異なる色調であるが黄色の印象を感じる。
×：パントーンカラー７５０１Ｃ（黄色）とはやや異なるがほぼ同等の色調である。
××：パントーンカラー７５０１Ｃ（黄色）と同等の色調である。
⊚: The color tone is the same as that of Pantone color 7527C (gray), and the impression of yellow is not felt at all.
◯: The color tone is lighter than that of Pantone color 7527C (gray), but the impression of yellow is hardly felt.
Δ: The color tone is different from the Pantone color 7501C (yellow), but the impression of yellow is felt.
X: The color tone is slightly different from that of the Pantone color 7501C (yellow), but is almost the same.
XX: The color tone is equivalent to that of Pantone color 7501C (yellow).
比較例１〜４に示すように、青色を呈する水溶性化合物と赤色を呈する水溶性化合物とを混合することで紫色に調製した美白髪剤は、黄ばんだ白髪をグレーの白髪に色補正することはできない。一方、実施例１〜５に示すように、紫色を呈する水溶性化合物を配合した美白髪剤は、黄ばんだ白髪をグレーの白髪に色補正でき、美しい白髪の印象を与えることができた。 As shown in Comparative Examples 1 to 4, the whitening agent prepared to be purple by mixing a water-soluble compound exhibiting blue color and a water-soluble compound exhibiting red color corrects yellowish gray hair to gray gray hair. Can't. On the other hand, as shown in Examples 1 to 5, the whitening agent containing a water-soluble compound exhibiting purple color could correct the color of yellowish gray hair to gray gray hair, and could give the impression of beautiful gray hair.
処方例
表２に示す処方の美白髪剤を調製した。いずれの美白髪剤も、黄ばんだ白髪をグレーの白髪に色補正でき、美しい白髪の印象を与えることができた。
Formulation Example A whitening agent having the formulation shown in Table 2 was prepared. All of the whitening agents were able to color-correct yellowish gray hair to gray gray hair and give the impression of beautiful gray hair.
