PROBLEM TO BE SOLVED: To provide a two-pack type foamy hair dye product using a non-aerosol foamer container, which is excellent in storage stability, has good dyeability, and is also excellent in the shampoo robustness after hair dyeing.SOLUTION: The two-pack type hair dye product includes a first preparation containing an alkali agent, a second preparation containing hydrogen peroxide, and a non-aerosol foamer container for discharging the liquid mixture of the first and second preparations in the form of a foam. The following components (A) and (B) are contained in the liquid mixture: (A) a polymer or a copolymer in which the molar fraction of a diallyl dimethyl quaternary ammonium salt monomer is 70% or more and (B) an N-acylamino acid salt, an N-acyl-N-alkylamino acid salt, or an ether carboxylic acid salt. The equivalent ratio of the anion site of the component (B) to the cation site of the component (A) (anion/cation) is more than 1, and the liquid mixture has a viscosity at 25°C of 1-300 mPa s.COPYRIGHT: (C)2011,JPO&INPIT【課題】保存安定性に優れ、しかも染色性も良好であり、染毛後のシャンプー堅牢性にも優れる、ノンエアゾールフォーマー容器を用いた泡状の二剤式染毛剤の提供。【解決手段】アルカリ剤を含有する第1剤と過酸化水素を含有する第2剤、及び第1剤と第2剤の混合液を泡状に吐出するノンエアゾールフォーマー容器からなり、混合液中に次の成分(A)及び(B)(A) ジアリルジメチル4級アンモニウム塩モノマーのモル分率が70%以上である重合体又は共重合体(B) N-アシルアミノ酸塩、N-アシル-N-アルキルアミノ酸塩、又はエーテルカルボン酸塩を含有し、成分(B)のアニオンサイトと成分(A)のカチオンサイトとの当量比(アニオン/カチオン)が1より大きく、かつ混合液の25℃における粘度が1~300mPa・sである二剤式染毛剤。【選択図】なし
