Description
本発明は、毛髪用化粧料に関する。 The present invention relates to hair cosmetics.
一般的な縮毛矯正剤は、チオグリコール酸やシステアミン等の還元剤、アンモニアやモノエタノールアミン等のアルカリ剤、過酸化水素等の酸化剤が含まれており、それらの作用により毛髪のクセを矯正する事が出来る。しかし、還元剤やアルカリ剤は毛髪にダメージを与えるため、処理後の毛髪の感触が悪くなり、また、繰り返し施術による断毛等のトラブルが発生する。
そのため、近年では還元剤や酸化剤を使用せずにクセ抑制効果を与える毛髪処理剤が開示されている。特許文献１では、グリオキシル酸とグアニジン塩及び／又は尿素とを含有し、ｐＨが１．０～２．５である毛髪処理剤が提案されている。また、特許文献２では、グリオキシル酸とグルコノラクトン及びエルカラクトンから選択される１種以上とを特定の配合比率で含有し、ｐＨが２．０～３．８の範囲である毛髪処理剤が提案されている。
しかしながら、これらの毛髪処理剤は強い酸性条件で処理するため、毛髪が過度に収斂し、処理後の毛髪の感触が悪くなる。また、ヘアカラーをしている毛髪に対しては、ヘアカラーを褪色させるという課題がある。
Typical hair straightening agents contain reducing agents such as thioglycolic acid and cysteamine, alkaline agents such as ammonia and monoethanolamine, and oxidizing agents such as hydrogen peroxide. It can be corrected. However, reducing agents and alkaline agents damage the hair, resulting in poor texture of the hair after treatment and problems such as hair breakage due to repeated treatments.
Therefore, in recent years, hair treatment agents have been disclosed that provide curl-suppressing effects without using reducing agents or oxidizing agents. Patent Document 1 proposes a hair treatment agent containing glyoxylic acid, a guanidine salt and/or urea, and having a pH of 1.0 to 2.5. Further, Patent Document 2 discloses a hair treatment agent containing glyoxylic acid and one or more selected from gluconolactone and erucalactone in a specific blending ratio and having a pH in the range of 2.0 to 3.8. Proposed.
However, since these hair treatment agents are treated under strongly acidic conditions, the hair becomes excessively astringent, resulting in poor feel of the hair after treatment. Furthermore, for colored hair, there is a problem in that the hair color fades.
本発明は、毛髪のクセ抑制効果に優れ、繰り返し施術を行っても毛髪の柔らかさや指通りが良好であり、ヘアカラーの褪色が少ない毛髪用化粧料を提供することを目的とする。 An object of the present invention is to provide a hair cosmetic that has an excellent effect of suppressing hair curl, has good softness and smoothness even after repeated treatments, and has less fading of hair color.
本発明者らは、鋭意研究を行った結果、（Ａ）カルボキシメチルシステイン又はその塩、（Ｂ）塩基性アミノ酸又はその塩、（Ｃ）有機アルカリ剤を含有し、前記（Ａ）成分に対する（Ｂ）成分のモル比率［（Ｂ）／（Ａ）］が１．０２～１０．０であり、ｐＨが６．５～９．５であることを特徴とする毛髪用化粧料が、毛髪のクセ抑制効果に優れ、繰り返し施術を行っても毛髪の柔らかさや指通りが良好であり、ヘアカラーの褪色が少ないことを見出した。
本発明において、（Ｂ）塩基性アミノ酸又はその塩が、リシン又はその塩であるものは、特に好ましい。
本発明において、（Ｃ）有機アルカリ剤が、アルカノールアミンであるものは、特に好ましい。
As a result of intensive research, the present inventors found that (A) carboxymethylcysteine or its salt, (B) basic amino acid or its salt, and (C) an organic alkaline agent are contained, and the B) A hair cosmetic having a molar ratio [(B)/(A)] of 1.02 to 10.0 and a pH of 6.5 to 9.5, It has been found that it has an excellent curl-suppressing effect, that even after repeated treatments, the hair remains soft and easy to run through, and that the hair color does not fade easily.
In the present invention, it is particularly preferable that the basic amino acid (B) or its salt is lysine or its salt.
In the present invention, it is particularly preferable that the organic alkaline agent (C) is an alkanolamine.
本発明によれば、毛髪のクセ抑制効果に優れ、繰り返し施術を行っても毛髪の柔らかさや指通りが良好であり、ヘアカラーの褪色が少ない毛髪用化粧料を提供することができる。 According to the present invention, it is possible to provide a hair cosmetic that is excellent in the effect of suppressing hair curl, has good softness and smoothness of hair even after repeated treatments, and has little fading of hair color.
本発明の毛髪用化粧料は、（Ａ）カルボキシメチルシステイン又はその塩（以下「（Ａ
）成分」ということもある）、（Ｂ）塩基性アミノ酸又はその塩（以下「（Ｂ）成分」ということもある）、（Ｃ）有機アルカリ剤（以下「（Ｃ）成分」ということもある）を含有し、前記（Ａ）成分に対する（Ｂ）成分のモル比率［（Ｂ）／（Ａ）］が１．０２～１０．０であり、ｐＨが６．５～９．５であることを特徴とするものである。
The hair cosmetic of the present invention comprises (A) carboxymethylcysteine or a salt thereof (hereinafter referred to as "(A
), (B) a basic amino acid or its salt (hereinafter sometimes referred to as ``component (B)''), (C) an organic alkaline agent (hereinafter sometimes referred to as ``component (C)'') ), the molar ratio of component (B) to component (A) [(B)/(A)] is 1.02 to 10.0, and the pH is 6.5 to 9.5.

製した。
なお表中の数値は質量％を示し、水の残部とは全量を１００質量％とするのに要する量である。
表中のモル比率［（Ｂ）／（Ａ）］について説明すると、例えば実施例１においては、（Ａ）成分としてカルボキシメチルシステイン（分子量：１７９．１９）を０．０１質量％と（Ｂ）成分としてリシン（分子量：１４６．１９）を０．０１質量％含有しているが、この場合、毛髪用化粧料１００ｇ中における（Ａ）成分のモル数は、０．０１／１７９．１９＝０．００００５５８モル、（Ｂ）成分のモル数は、０．０１／１４６．１９＝０．００００６８４モルとなるため、モル比率［（Ｂ）／（Ａ）］は１．２２６となる。
同様に、実施例４においては、（Ａ）成分としてカルボキシメチルシステインリシンを（分子量：３２５．３８）５質量％と（Ｂ）成分としてリシンを０．５質量％含有しているが、この場合、毛髪用化粧料１００ｇ中における（Ａ）成分のモル数は、５／３２５．３８＝０．０１５３７モル、（Ｂ）成分のモル数は、カルボキシメチルシステインリシン由来のモル数とリシン由来のモル数との合計、すなわち（５／３２５．３８）＋（０．５／１４６．１９）＝０．０１８７９モルとなるため、モル比率［（Ｂ）／（Ａ）］は１．２２３となる。

The values in the table indicate mass %, and the remainder of water is the amount required to make the total amount 100 mass %.
Regarding the molar ratio [(B)/(A)] in the table, for example, Example 1 contains 0.01 mass% of carboxymethylcysteine (molecular weight: 179.19) as the component (A) and 0.01 mass% of lysine (molecular weight: 146.19) as the component (B). In this case, the number of moles of the component (A) in 100 g of the hair cosmetic is 0.01/179.19 = 0.0000558 moles, and the number of moles of the component (B) is 0.01/146.19 = 0.0000684 moles, so the molar ratio [(B)/(A)] is 1.226.
Similarly, Example 4 contains 5 mass% of carboxymethylcysteine lysine (molecular weight: 325.38) as the component (A) and 0.5 mass% of lysine as the component (B). In this case, the number of moles of component (A) in 100 g of the hair cosmetic is 5/325.38 = 0.01537 moles, and the number of moles of component (B) is the sum of the number of moles derived from carboxymethylcysteine lysine and the number of moles derived from lysine, that is, (5/325.38) + (0.5/146.19) = 0.01879 moles, and the molar ratio [(B)/(A)] is 1.223.
