Abstract: A carbonated aerosol external preparation for skin, including a stock solution containing the following components (A) to (C), and a propellant containing the following component (D): (A) heparinoid, (B) water-soluble polymer, (C) water, and (D) carbon dioxide gas. The carbonated aerosol external preparation for skin has a pH immediately after discharge of 4.0 or more and 7.0 or less. The component (B) includes one or more selected from the group consisting of hydroxypropylmethylcellulose and acrylic acid/alkyl (meth)acrylate copolymer. A content of the component (B) in the stock solution is from 0.05 to 5.0% by mass, based on a total mass of the stock solution.

Abstract: A carbonated aerosol external preparation for skin, including a stock solution containing the following components (A) to (D) and a propellant including the following component (E): (A) a ceramide lipid, (B) an ionic surfactant, (C) a water-soluble polymer, (D) water, (E) carbon dioxide gas. A content of the component (A) in the stock solution is from 0.075 to 5.0% by mass, and a content of the component (B) in the stock solution is from 0.05 to 2.0% by mass, based on a total mass of the stock solution. A mass ratio of the component (C) to the component (B), (C)/(B), in the stock solution, is from 0.20 to 1.5.
