Abstract

An aerosol composition including an aerosol stock solution containing a cationic surfactant (A) and a linear saturated higher alcohol (B), and a propellant (C) containing carbon dioxide. The component (A) containing a mono-long-chain-alkyl cationic surfactant (A1). A content of the component (A) being 0.9% by mass or more and less than 6.0% by mass in the aerosol stock solution. A molar ratio [(B)/(A1)] of the component (B) with respect to the component (A1) being 3.0 or more and 7.0 or less in the aerosol stock solution. A content of the component (A1) in the component (A) being 90% by mass or more and 100% by mass or less, and a difference between a number of carbon atoms of the long-chain alkyl in the component (A1) and the number of carbon atoms of the component (B) being 0.
