Propellant
A propellant is a gas, liquid or plasma used to move an object by applying a motive force. Common propellants are gasoline, jet fuel and rocket fuel.
In aerosol cans, the propellant is simply a compressed gas. Chlorofluorocarbons were once often used, but have been replaced in recent years due to the negative effects CFCs have on Earth's atmospheric ozone layer.
