Description

本発明は、染着除去剤に関し、特に酸性染料を含有した染毛料を使用する際に、頭皮、手、肌などに付着した染料の汚れを除去するための染着除去剤に関する。 TECHNICAL FIELD The present invention relates to a stain remover, and more particularly to a stain remover for removing dye stains adhering to the scalp, hands, skin, etc. when using a hair dye containing an acid dye.

毛髪を染毛する手段として、酸性染料を含有したヘアマニキュアや塩基性染料を含有したカラートリートメントなどの使用があるが、中でもヘアマニキュアに含有されている酸性染料は皮膚に染着しやすい。 Hair manicures containing acid dyes and color treatments containing basic dyes are used as a means for dyeing hair. Among them, acid dyes contained in hair manicures tend to stain the skin.

従来、皮膚に染着した染毛料の汚れを落とすためには、有機溶剤を含む染着除去剤、あるいは石鹸液やシャンプーなどが使用されてきたが、それらの多くは液状であり、使用する際にはティッシュやコットンなどに含浸させて染着部分を何度もこすり取るという方法が一般的である。しかし、皮膚に染着した染毛料の汚れをこすり取る方法は、皮膚へ摩擦による刺激を与えるという欠点がある。 Conventionally, stain removers containing organic solvents, soap solutions, shampoos, etc. have been used to remove stains from hair dyes that have adhered to the skin. In general, a method of soaking a tissue or cotton and rubbing the dyed part many times is common. However, the method of rubbing off stains of the hair dye on the skin has the drawback of giving irritation to the skin due to friction.

特許文献1の染着除去剤は液状であるため、使用する際にはティッシュやコットンなどに含浸させ、染着部分に当てて、しばらく放置する必要があり、コットンからの液垂れが懸念され含浸量は少なくなり、染着除去は弱くなってしまう。そこで、製剤の粘度を高め、染着部に十分な量を塗布し、たれ落ちを防ぐことができる染着除去剤の開発が望まれていた。 Since the stain removing agent of Patent Document 1 is in liquid form, it is necessary to impregnate a tissue or cotton before using it, apply it to the dyed part, and leave it for a while. The amount will be less and the stain removal will be weaker. Therefore, it has been desired to develop a stain remover that can increase the viscosity of the formulation, apply a sufficient amount to the dyed part, and prevent dripping.
