Description
本発明は、染毛剤組成物及びそれを用いた染毛方法に関する。 The present invention relates to a hair dye composition and a hair dyeing method using the same.
染毛剤は、使用される染料によって、又はメラニンの脱色作用を有するか否かによって分類される。代表的なものとしては、アルカリ剤及び酸化染料を含有する第１剤と、酸化剤を含有する第２剤からなる二剤式の永久染毛剤、有機酸又はアルカリ剤と、酸性染料、塩基性染料、ニトロ染料等の直接染料を含有する一剤式の半永久染毛剤などがある。 Hair dyes are classified according to the dye used or whether they have a melanin decolorization effect. Typical examples include a two-part permanent hair dye, an organic acid or an alkali agent, an acid dye, a base comprising a first agent containing an alkali agent and an oxidation dye, and a second agent containing an oxidation agent. One-part semi-permanent hair dyes containing direct dyes such as sex dyes and nitro dyes.
しかし、直接染料は、一剤式の半永久染毛剤に使用する場合、洗浄や光によって比較的容易に毛髪上から失われてしまうため、褪色しやすく、これは損傷を受けた毛髪において著しい。 However, direct dyes, when used in one-part semi-permanent hair dyes, are easily lost from the hair by washing and light and are therefore easily faded, which is noticeable in damaged hair.
また、酸化剤を用いた二剤式の永久染毛剤においても、酸化染料によるあまり鮮明でない色調を補うため、ニトロ染料、塩基性染料等の直接染料を用いることが試みられている。しかしながら、ニトロ染料を用いた場合には、染毛直後は鮮やかであるものの、経日での色落ちが著しく、色がくすみ易いという問題があり、塩基性染料を用いた場合には、酸化剤としての過酸化水素と混合すると分解し易いといった問題点があった。 In addition, in a two-component permanent hair dye using an oxidizing agent, it has been attempted to use a direct dye such as a nitro dye or a basic dye in order to compensate for a less clear color tone due to the oxidizing dye. However, when a nitro dye is used, it is vivid immediately after hair dyeing, but there is a problem that the color fading with the passage of time is remarkable and the color is faint, and when a basic dye is used, an oxidizing agent is used. When mixed with hydrogen peroxide, there is a problem that it is easily decomposed.
これらの問題点を解決した鮮明な染毛が可能で安定な染毛剤組成物として、解離性プロトンを有する解離性アゾ染料を直接染料として用いる染毛剤が提案されている（特許文献１）。 A hair dye using a dissociable azo dye having a dissociating proton as a direct dye has been proposed as a stable hair dye composition capable of clear hair dyeing that solves these problems (Patent Document 1). .
解離性アゾ染料は、アルカリ性下、解離性プロトンが解離した状態で染毛性を発揮する。この解離性アゾ染料と、染毛後の毛髪の感触を向上させるカチオン界面活性剤とを併用した場合、プロトンを解離してアニオン性となったアゾ染料がカチオン界面活性剤との間で難溶性の塩を形成してしまう。このため、配合時に染毛剤組成物系内で沈殿を生じ、配合時の操作性が悪くなると共に外観も悪くなるという問題に加え、使用時に染毛後の毛髪に対して優れた感触を付与することが難しいといった問題があった。 The dissociable azo dye exhibits hair dyeability in a state where dissociable protons are dissociated under alkalinity. When this dissociable azo dye is used in combination with a cationic surfactant that improves the feel of the hair after dyeing, the azo dye that has become anionic by dissociating protons is poorly soluble in the cationic surfactant. Will form a salt. For this reason, precipitation occurs in the hair dye composition system at the time of blending, and in addition to the problem that the operability at the time of blending deteriorates and the appearance also deteriorates, it gives an excellent feel to the hair after dyeing at the time of use There was a problem that it was difficult to do.
従って、本発明は、染毛性に優れる解離性アゾ染料と使用後の毛髪の感触が優れるカチオン界面活性剤とが安定に配合され、毛髪への適用時には滑らかに染毛剤を塗り広げることができ、同時に染毛後の毛髪に対して優れた感触（滑らかさ等）を付与することができる染毛剤組成物に関する。 Therefore, in the present invention, the dissociable azo dye having excellent hair dyeing properties and the cationic surfactant having excellent hair feel after use are stably blended, and when applied to hair, the hair dye can be applied smoothly. It is related with the hair dye composition which can provide the touch (smoothness etc.) which was able to be performed to the hair after dyeing simultaneously.
本発明者らは、特定構造の解離性アゾ染料にあっては、弱アルカリ性ないしアルカリ性条件下、アニオン界面活性剤を共存させれば、カチオン界面活性剤を含むアルカリ性溶液とした場合でも、解離性アゾ染料とアニオン界面活性剤の合計量に対するカチオン界面活性剤の比が一定値以下であれば、染毛剤系内に沈殿を生じることなく安定に配合でき、染毛後の毛髪に対して優れた感触を付与することができることを見出した。 In the dissociable azo dye having a specific structure, the present invention provides a dissociation property even in the case of an alkaline solution containing a cationic surfactant, if an anionic surfactant is present under weakly alkaline or alkaline conditions. If the ratio of the cationic surfactant to the total amount of the azo dye and the anionic surfactant is less than a certain value, it can be blended stably without causing precipitation in the hair dye system, and is excellent for hair after hair dyeing. It was found that the touch can be imparted.
