chlorofluorocarbon

(klôr′ō-flo͝or′ō-kär′bən, -flôr′-)
n. Abbr. CFC
Any of various halocarbon compounds consisting of carbon, hydrogen, chlorine, and fluorine, once used widely as aerosol propellants and refrigerants. Volatile chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer.

chlorofluorocarbon

(klōr″ō-floor″ō-kar′bŏn) [ chloro- + fluorocarbon],

CFC

A fluorinated hydrocarbon, formerly used in metered dose inhalers as a propellant gas. CFCs accumulate in and damage the ozone layer of the stratosphere.
