| 摘要 |
A stable water-containing aerosol system having carbon dioxide as the propellant and containing an amine which reversibly reacts with carbon dioxide or the reaction product of water and carbon dioxide which amine is added in an amount sufficient to adjust the pH of the system to the near neutral to slightly alkaline range is disclosed. Another solvent in which carbon dioxide is soluble, such as odorless mineral spirits, may be added to the system to serve as a reservoir for carbon dioxide gas necessary to maintain the pressure in the aerosol system as it is exhausted. The aerosol system is relatively noncorrosive in conventional aerosol containers.
