PROBLEM TO BE SOLVED: To substantially reduce the volume and weight of the container of a hair dye first agent which is used in large quantity in a beauty salon to reduce a storage space of the hair dye first agent and to substantially reduce the disposal amount of an aluminum tube discarded after use.SOLUTION: The hair dye first agent prepared by simultaneously blending ammonia in an amount of 2.5-5.6% and ammonium bicarbonate in an amount of 2-5% is mixed, as an alkali agent, with a hair dye second agent including hydrogen peroxide in an amount of 6% or lower, in a weight ratio of the former to the latter of 1:4 to 1:8, and then the resultant mixture is used as a hair dye. The hair dye first agent composition in an amount of 13-25 g is filled into a small-sized aluminum tube which has an interior content of 15-30 mL and of which the inner surface is coated with epoxy phenol. The used amount per person of the hair dye first agent is reduced from one third to one fifth of the conventional used amount while maintaining and improving the capability of the hair dye, thus achieving the miniaturization of a container, the reduction of storage space of a beauty salon, and the reduction of the amount of trash.COPYRIGHT: (C)2010,JPO&INPIT【課題】美容室で大量に使用される染毛剤第一剤の容器の容積並びに重量を大幅に削減し保管スペースの削減と使用後に廃棄されるアルミチューブの廃棄量の大幅削減を行う。【解決手段】アルカリ剤としてアンモニアを2.5%以上5.6%以下と重炭酸アンモニュウムを2%以上5%以下とを同時に配合した染毛剤第一剤と過酸化水素を6%以下含有する染毛剤第二剤を1:4から1:8で混合して使用する染毛剤、および該染毛剤第一剤組成物25g以下13g以上をエポキシフェノールで内面コートした内容量30ml以下15ml以上の小型アルミニュウムチューブに充填した染毛剤。染毛剤第一剤の一人当たりの使用量を染毛剤の性能を維持向上しながら従来の三分の一から五分の一にすることにより容器の小型化を実現し美容室の保管スペースの低減とごみの量の低減を実現する。【選択図】なし
