Aerosol spray cans often contain Butane

Butane is an organic compound with the chemical formula CH. It is an alkane with four carbon atoms. It is used as a fuel (sometimes with propane) and in aerosol cans.

Uses of Butane

Butane is sold in canisters, for cooking and camping. It is also used as fuel in cigarette lighters, and as propellant in aerosol sprays or deodorants. Some kinds of Butane are used in refrigerators.

Mixtures with Propane are known as LPG.

Dangers

Butane can be hazardous. Inhalation can lead to death by asphyxiation due to displacement of oxygen in the lungs. Contact with the skin can lead to frostbite. If the gas is mixed with air and ignighted it is prone to explode like many other fuels that are volatile
