Description
本発明は、還元剤や酸化剤を含まずに、ヘアカラーをしたクセ毛に対してヘアカラーの退色を抑えながら直毛化することができる毛髪処理剤に関する。また、当該毛髪処理剤を用いることにより、ヘアカラーの退色を抑えながら毛髪を直毛化できる毛髪処理方法にも関する。
The present invention relates to a hair treatment agent that does not contain a reducing agent or an oxidant and can straighten hair while suppressing the fading of the hair color with respect to the hair color. In addition, the present invention relates to a hair treatment method capable of making hair straight while suppressing discoloration of the hair color by using the hair treatment agent.
一般的な縮毛矯正剤は、主成分の還元剤、酸化剤の作用及び高温での機械的処理により毛髪を直毛化することができる。具体的には、チオグリコール酸又はその塩、システアミン又はその塩等の還元剤と、アンモニア水、モノエタノールアミン、炭酸水素アンモニウム等のアルカリ剤を含有する第１剤を毛髪に塗布することで、毛髪に存在するジスルフィド結合を還元し、毛髪を高温での機械的処理によりストレート状に伸ばした上で、過酸化水素あるいは臭素酸ナトリウム等の酸化剤を含有する第２剤で処理して、ジスルフィド基を酸化し、毛髪をストレート状に固定する。
General hair straighteners can make hair straight by the action of reducing agents and oxidizing agents as main components and mechanical treatment at high temperatures. Specifically, by applying to the hair a first agent containing a reducing agent such as thioglycolic acid or a salt thereof, cysteamine or a salt thereof, and an alkaline agent such as aqueous ammonia, monoethanolamine, or ammonium bicarbonate, Disulfide bonds present in the hair are reduced, and the hair is straightened by mechanical treatment at high temperature, and then treated with a second agent containing an oxidizing agent such as hydrogen peroxide or sodium bromate to obtain disulfide. Oxidizes the group and fixes the hair straight.
しかし、還元剤、酸化剤の作用はヘアカラーを退色させるとともに毛髪ダメージを伴うことが多く、処理後の時間経過に伴い毛髪の感触が悪くなる。このため還元剤や酸化剤を含まずに、ヘアカラーをしているクセ毛を直毛化することができる毛髪処理剤の開発が望まれている。
However, the action of the reducing agent and the oxidizing agent often causes the hair color to fade and damage the hair, and the hair feels worse over time after the treatment. For this reason, the development of a hair treatment agent that does not contain a reducing agent or an oxidizing agent and can straighten hairs that are hair color is desired.
還元剤や酸化剤を含まない毛髪処理剤としては、毛髪矯正成分としてグリオキシル酸を用いる方法が提案されている。例えば、特許文献１には、グリオキシル酸を含む溶液を毛髪に塗布して放置し、乾燥後に、毛髪矯正アイロンにより約２００±５０℃で毛髪を矯正する方法が開示されている。この方法では、毛髪のダメージを抑えながら毛髪を半永久的に矯正できるが、ヘアカラーをしているクセ毛に適用した時、ヘアカラーを退色させてしまう。さらに、特許文献２には、グリオキシル酸を１５．０～２５．０質量％とグアニジン塩及び／又は尿素を含むｐＨ１．０～２．５の溶液を毛髪に塗布して放置し、水洗、毛髪を乾燥させた後に、整髪用アイロンにより１４０～２００℃で毛髪を矯正する方法が開示されている。この方法でも、毛髪のダメージを抑えながら毛髪を矯正できるが、ヘアカラーをしているクセ毛に適用した時、ヘアカラーを退色させてしまう。
As a hair treatment agent that does not contain a reducing agent or an oxidizing agent, a method using glyoxylic acid as a hair straightening component has been proposed. For example, Patent Document 1 discloses a method in which a solution containing glyoxylic acid is applied to hair and left standing, and after drying, the hair is straightened at about 200 ± 50 ° C. with a hair straightening iron. In this method, the hair can be semipermanently corrected while suppressing damage to the hair, but when applied to the hair that has a hair color, the hair color is faded. Further, in Patent Document 2, a solution having a pH of 1.0 to 2.5 containing 15.0 to 25.0% by mass of glyoxylic acid and a guanidine salt and / or urea is applied to the hair and allowed to stand. A method of straightening hair at 140 to 200 ° C. with a hair styling iron after drying the hair is disclosed. Even with this method, the hair can be corrected while suppressing damage to the hair, but the hair color is faded when applied to the hair having the hair color.
本発明は、前記従来技術の欠点に鑑みてなされたものであり、ヘアカラーを退色させると共にダメージを与える還元剤や酸化剤を用いず、さらに、ヘアカラーを退色させるグリオキシル酸を含有する毛髪処理剤の欠点を解消した、毛髪直毛化のための毛髪処理剤と毛髪処理方法を提供することを目的とする。
The present invention has been made in view of the drawbacks of the prior art, and does not use a reducing agent or an oxidizing agent that fades and damages the hair color, and further contains a glyoxylic acid that fades the hair color. An object of the present invention is to provide a hair treatment agent and a hair treatment method for straightening hair, which eliminates the drawbacks of the agent.
本発明者は、前記の課題を解決すべく鋭意研究を重ねた結果、特定のリン酸化合物を特定量含有し、ｐＨが３．５～１０．０の範囲に調整することにより、還元剤や酸化剤によらずに、ヘアカラーを退色させるグリオキシル酸の欠点を解消し、ヘアカラーをしたクセ毛に、ヘアカラーの退色を抑えながら、直毛化を実現できることを見出し、本発明を完成するに至った。
As a result of intensive studies to solve the above problems, the present inventor has a specific amount of a specific phosphoric acid compound and a pH adjusted to a range of 3.5 to 10.0. The present invention has been completed by finding that straight hair can be achieved while suppressing the fading of the hair color to the hair that has been colored, eliminating the disadvantages of glyoxylic acid that causes the hair color to fade, regardless of the oxidizing agent. It came to.
