ROFL.
You are incorrect, sir.

Ingredient name: 1,1,1,2-Tetraflurorethane (R134a)
Wikipedia for Tetraflurorethane:
1,1,1,2-Tetrafluoroethane - Wikipedia, the free encyclopedia
1,1,1,2-Tetrafluoroethane, also called simply tetrafluoroethane, R-134a, Genetron 134a, or HFC-134a, is a haloalkane refrigerant without an ozone depletion potential and thermodynamic properties similar to R-12 (dichlorodifluoromethane). It has the formula CH2FCF3, and a boiling point of −26.6 °C (−15.9 °F).
Uses:
1,1,1,2-Tetrafluoroethane is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. Other uses include plastic foam blowing, as a cleaning solvent and as a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), canned air, and in air driers, i.e., for removing the moisture from compressed air. Moisture present in compressed air has a harmful effect on pneumatic systems. Tetrafluoroethane has also been used to cool computers in some overclocking attempts. It is also commonly used as a power source for airsoft airguns.
Wikipedia for 'Canned Air':
Gas duster - Wikipedia, the free encyclopedia
Gas duster (also referred to as canned air) is a product consisting of liquified difluoroethane, trifluoroethane, or tetrafluoroethane in a spray can, with a long nozzle that enables the user to direct a precisely focused blast of gas. Gas dusters do not use compressed air, but other inert gases that are much easier to compress into a liquid state. Hydrocarbons, like butane, were often used in the past, but their flammability forced manufacturers to use fluorocarbons.
