To provide a second agent composition that can achieve stable discharge of an agent from an aerosol container and provides stable hair dyeing/bleaching effects by minimizing the use of ionic surfactant and keeping the viscosity constant from before the agent is filled into the aerosol container to after it is discharged from the aerosol container.SOLUTION: Provided is a second agent composition for an aerosol-type hair dye or bleach to be used by mixing with a first agent composition containing an alkaline agent, the second agent composition containing the following components (A) to (D): (A) hydrogen peroxide; (B) a nonionic surfactant; (C) a higher alcohol; and (D) hydrocarbons, the mass ratio [(C)+(D)]/(B) being 1.0 or more and 3.5 or less, the mass ratio (D)/(C) being 1.3 or more and 2.1 or less, and the viscosity immediately after being discharged from the container being 10,000 mPa s or more and 100,000 mPa s or less.SELECTED DRAWING: None 【課題】イオン性界面活性剤をできるだけ用いることなく、エアゾール容器への剤の充填前からエアゾール容器から吐出された後までの粘度を一定に保つことで、エアゾール容器からの剤の安定な吐出を実現し、安定した染毛／脱色効果を得ることができる第２剤組成物の提供。【解決手段】アルカリ剤を含有する第１剤組成物と混合して使用するエアゾール型染毛用又は毛髪脱色用第２剤組成物であって、下記成分(A)～(D)を含有し、質量比〔(C)＋(D)〕／(B)が1.0以上3.5以下、質量比(D)／(C)が1.3以上2.1以下であり、容器から吐出させた直後の粘度が10,000mPa・s以上100,000mPa・s以下である、エアゾール型染毛用又は毛髪脱色用第２剤組成物。(A) 過酸化水素(B) 非イオン界面活性剤(C) 高級アルコール(D) 炭化水素【選択図】なし
