Description
本発明は、二剤式染毛剤に関する。 The present invention relates to a two-component hair dye.
従来、毛髪脱色剤、染毛剤といった毛髪化粧料としては、液状又はクリーム状のものが普及しているが、これらを毛髪にムラなく塗布するのは難しい。特に、毛髪の根元部分や後頭部の塗布にはブロッキング、合わせ鏡等のスキルが必要とされ、多くの時間も要する。 Conventionally, liquid or cream-like hair cosmetics such as hair bleaching agents and hair dyes have been widely used, but it is difficult to apply them uniformly to hair. In particular, skills such as blocking and a matching mirror are required for applying the root portion and the back of the hair, and a lot of time is required.
そこで、剤を泡状に吐出することで、染毛操作を簡便化することが提案されており、例えば、二剤式エアゾールタイプのものや１剤式ノンエアゾールタイプのものが知られている。しかし、二剤式エアゾールタイプには、脱色ムラや染色ムラが生じやすい、金属製の耐圧容器等が過酸化水素により酸化され腐食する、過酸化水素の分解によって耐圧容器の内圧が過度に上昇するといった問題があり、また１剤式ノンエアゾールタイプには、一度の施術で得られる効果に乏しいため、塗布後に長時間放置したり、施術を繰り返したりすることが必要で煩雑であるという問題がある。 Therefore, it has been proposed to simplify the hair dyeing operation by discharging the agent in the form of foam. For example, two-component aerosol type and one-agent non-aerosol types are known. However, the two-part aerosol type is prone to decolorization and dyeing unevenness. Metal pressure vessels are oxidized and corroded by hydrogen peroxide, and the internal pressure of the pressure vessel rises excessively due to the decomposition of hydrogen peroxide. In addition, the one-agent non-aerosol type has a problem that it is difficult to leave for a long time after application or to repeat the treatment because the effect obtained by one treatment is poor. .
これに対し、二剤式毛髪脱色剤又は二剤式染毛剤をノンエアゾールタイプのフォーマー容器から泡状に吐出させるものが提案されている（特許文献１参照）。これは、第１剤と第２剤の混合液をフォーマー容器から泡状に吐出することにより、毛髪にムラなく適用でき、仕上がりに色ムラが生じず、特に新生部と既染部の色の段差を解消するのに有用なものである。 On the other hand, what discharge | releases a two-component hair bleaching agent or a two-component hair dye from a non-aerosol type | former container in foam form is proposed (refer patent document 1). This is because the liquid mixture of the first agent and the second agent is discharged from the former container in the form of foam, so that it can be applied to the hair without any unevenness and color unevenness does not occur in the finish. It is useful for eliminating the level difference.
染毛に際しては、毛髪（特に頭髪、以下同様）の表面に整髪料が存在すると染毛性の低下や色ムラの原因となり、一方、髪が濡れていても液ダレや色ムラの原因となる。このため、染毛の前に、まず洗髪して整髪料を落とした後、ドライヤー等を用いて髪をよく乾かしておくのが施術上の常識となっている。 When hair is dyed, the presence of hair styling on the surface of hair (especially hair, the same shall apply hereinafter) causes a reduction in hair coloring and color unevenness. On the other hand, even if the hair is wet, it causes liquid dripping and color unevenness. . For this reason, it is common practice to treat hair before hair dyeing by first washing the hair and removing the hair-styling material, and then drying the hair well using a dryer or the like.
前述のノンエアゾールタイプの二剤式染毛剤は、簡便な操作でムラなく染毛が可能なものであるが、毛髪の表面に整髪料が存在すると、泡を毛髪に塗布する際や泡を頭髪上で保持する際に泡が消えやすくなる上、一層液ダレを起こしやすくなることから、整髪料の付いた髪に直接適用し難いという課題があり、洗髪と乾燥が必要である点は他のタイプの染毛剤と同様であった。 The above-mentioned non-aerosol type two-component hair dye can be uniformly dyed by simple operation, but if a hair styling agent is present on the surface of the hair, the foam is applied when the foam is applied to the hair. It is difficult to apply directly to hair with hair styling because bubbles easily disappear when held on the hair and it is more likely to cause dripping. It was the same as the type of hair dye.
そこで本発明は、特許文献１における特長を生かしたまま、整髪料の付いた毛髪であっても良好な泡性能（泡立ちや泡もち）及び良好な塗布性を有することにより、色ムラを生ずることなく染めることを可能としたノンエアゾールタイプの二剤式染毛剤を提供することを課題とする。 Therefore, the present invention produces color unevenness by taking advantage of the features of Patent Document 1 and having good foam performance (foaming and foaming) and good coatability even for hair with a hair styling agent. It is an object of the present invention to provide a non-aerosol type two-component hair dye that can be completely dyed.
本発明者らは、ノンエアゾールタイプの二剤式染毛剤における第１剤と第２剤の混合液中に、特定種かつ特定量の非イオン界面活性剤とカチオン界面活性剤とを組み合わせて使用することにより上記の目的を達成できることを見出した。 The present inventors combined a specific species and a specific amount of a nonionic surfactant and a cationic surfactant in a mixed liquid of the first agent and the second agent in the non-aerosol type two-component hair dye. It has been found that the above-mentioned purpose can be achieved by use.

更に本発明は、上記の二剤式染毛剤を用い、第１剤と第２剤との混合液をノンエアゾール・フォーマーから泡状に吐出させ、その泡を手を用いて頭髪に適用する頭髪の染毛方法を提供するものである。 Furthermore, the present invention uses the above-mentioned two-component hair dye, discharges a mixed solution of the first agent and the second agent in a foam form from a non-aerosol former, and applies the foam to the hair using a hand. The present invention provides a method for dyeing hair.
本発明によれば、ノンエアゾール・フォーマー容器から吐出された混合液の泡が、整髪料の付いた毛髪に対しても、良好な塗布性を有することにより簡便にムラなく塗布でき、更に、良好な泡性能（泡立ちや泡もち）を有することにより色ムラを生ずることなく染めることができる。 According to the present invention, the foam of the mixed liquid discharged from the non-aerosol foamer container can be applied easily and evenly to the hair with a hairstyling agent because it has good applicability, and even better. By having excellent foam performance (foaming and foaming), it can be dyed without causing color unevenness.
