Chlorofluorocarbons (CFCs) is a family of inert, nontoxic, and easily liquefied chemicals used in refrigeration, air conditioning, packaging, insulation, or as solvents and Aerosol propellants. Because CFCs are not destroyed in the lower atmosphere they drift into the upper atmosphere where their chlorine components destroy ozone. (See: fluorocarbons.)

Other /More definition:
Chlorofluorocarbons are Organic compounds made up of atoms of carbon, chlorine, and fluorine. An example is CFC-12 (CCl2F2, used as a refrigerant in refrigerators and air conditioners and as a foam blowing agent. Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules. See ozone depleting substance, fluorocarbons.
