PROBLEM TO BE SOLVED: To provide a foamable aerosol product which contains a propellant containing carbon dioxide and has excellent foamability and good foam quality.SOLUTION: The present invention is a foamable aerosol product which can be used as a shampoo and comprises [A] a liquid concentrate containing an anionic surfactant and [B] a propellant, both injected in a pressure-tight container. The propellant [B] comprises isopentane, a liquefied petroleum gas and carbon dioxide, and the ratio of the total mass of isopentane and the liquefied petroleum gas to the mass of the liquid concentrate [A] is 4/96 to 10/90 inclusive. In the foamable aerosol product, it is preferred that a case in which a hydrocarbon mixture fulfilling the requirements (1) and (2) mentioned below is injected in the pressure-tight container in an amount of 0.1 to 3 mass% inclusive is excluded: (1) a hydrocarbon mixture composed of hydrocarbons independently selected from hydrocarbons each having 3 to 5 carbon atoms and (2) a hydrocarbon mixture containing a saturated hydrocarbon having a vapor pressure of 0.1 MPa or more and less than 0.5 MPa at 35°C in an amount of 70 to 100 mass% inclusive.COPYRIGHT: (C)2014,JPO&INPIT【課題】二酸化炭素を含む噴射剤を含有し、かつ優れた発泡性及び良好な泡質を有する発泡性エアゾール製品の提供を目的とする。【解決手段】本発明は[A]アニオン性界面活性剤を含む原液及び[B]噴射剤が耐圧容器に充填されている発泡性エアゾール製品であって、[B]噴射剤がイソペンタン、液化石油ガス及び二酸化炭素を含み、イソペンタン及び液化石油ガスの合計の[A]原液に対する質量比が4/96以上10/90以下であり、シャンプーとして用いられる発泡性エアゾール製品である。当該発泡性エアゾール製品は、以下の条件(1)及び(2)を満たす炭化水素混合物が耐圧容器に0.1質量%以上3質量%以下充填されているものを除くことが好ましい。(1)炭素数が3~5の炭化水素から選ばれる炭化水素混合物。(2)35℃における蒸気圧が0.1MPa以上0.5MPa未満の飽和炭化水素を70質量%以上100質量%以下含む炭化水素混合物。【選択図】なし
