Aerosol propellant is a term commonly used in the aerosol industry to describe the gas that propels the contents of an aerosol dispenser. However, there are several synonyms that can be used interchangeably with aerosol propellant. Some examples of interchangeable terms include compressed gas, propellant gas, and aerosol gas. These synonyms can refer to several gases used in aerosol products such as hydrocarbons, fluorocarbons, and compressed air. Furthermore, it is important to note that with the growing concerns of the negative environmental impacts of some types of propellants, there is a shift towards using natural alternatives such as nitrogen, carbon dioxide, and compressed air.
