Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compounds in aerosol-spray propellants. Their use was discontinued under the Montreal Protocol.
advances of propellants used in aerosols
CFC
The typical gas used as a propellant in aerosol solvent based paint cans is Propane, Chemical Abstract Number 74-98-6. The propellant used will depend on the contents of the can, as it must be a chemical that is compatible with the contents. Most liquids can be put into an aerosol can. The liquid is placed into the can, the liquid is diluted to make it thin enough to spray through the nozzel of the spray can and then a compressed gas propellant is added to expel the contents of the container in the form of an aerosol.
An aerosol is a cloud of solid or liquid particles in a gas. I think you are asking if FDS contains a propellant. I believe the Isobutane in the product is used as a propellant and is also what makes the product flammable.
The aerosol-can uses compressed gas as a propellant.Since the product is liquid at room temperature, it is simply poured in before the can is sealed. The propellant, on the other hand, must be pumped in under high pressure after the can is sealed. When the propellent is kept under high enough pressure, it doesn't have any room to expand into a gas. It stays in liquid form.When the button is pressed the pressurized gas pushes the liquid product, as well as some of the liquid propellant, up the tube to the nozzle. Some cans, such as spray-paint cans, have a ball bearing inside. If you shake the can, the rattling ball bearing helps to mix up the propellant and the product, so the product is pushed out in a fine mist.Up until the 1980s, a lot of liquefied-gas aerosol cans used chlorofluorocarbons (CFCs) as a propellant. After scientists concluded that CFCs were harmful to the ozone layer, 70 nations signed the Montreal Protocol, an agreement to phase out CFC use over the next decade. Today, almost all aerosol cans contain alternative propellants, such as liquefied petroleum gas, which do not pose as serious a threat to the environment.
halon is another name. they deplete ozone.
It would be quite spectacular I think. The vacuum would cause the can to explode.

it is a can of compressed air with a chemical that will kill you if you use it as a inhalent...
Aerosol spray was created in 1941.
He was a chemical engineer that invented aerosol spray cans.
Spray and Wash was invented in the 1970's by Dow Chemical Company. The first Spray and Wash products were only available in aerosol cans.
An aerosol spray is a homogeneous mixture.
hair spray
Norwegian inventor. He filed the first patent for an aerosol-type dispenser in 1926. He later modified his original design, specifying a spray nozzle, and used hydrocarbons as the propellant gas.
