Best Answer

Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compound in aerosol-spray propellants. Their use has been discontinued under the Montreal Protocol. answer is: FLUOROCARBON..

Chlorofluorocarbons used to be the propellant of many aerosol sprays. They are no longer used because of the negative impact the chemicals had on the ozone layer.

Why should you not use too many aerosol sprays?

They have freon in them which damages the Ozone Layer


What is a fluorinated hydrocarbon?

HBFCs are a group of simple man-made chemicals that contain the elements hydrogen, fluorine and bromine. They are chemicals that damage the stratospheric ozone layer that protects earth from high levels of ultra violet radiation. They are used as solvents, degreasing agents, fire extinguishing agents and refrigerants.


Are some aerosol hair sprays worse than others?

That depends on what criteria you are applying. There are very few applications where an aerosol is actually necessary, so my opinion is that there's no point judging one against another. Hair sprays, for instance, are available as pump action sprays, so why use aerosols at all? Most aerosols these days do not contain CFC's but they are still very lacking in green credentials. If we are to conserve resources we need to recycle. One of the big difficulties with recycling is separating the constituents if different materials are mixed together, and in an aerosol can the materials are stuck together. So in a world where we are in danger of running out of things, to my mind aerosols are a stupid extravagance.


What is the chemical formula for hydrofluorocarbon 152a?

Hydrofluorocarbon R-152A is a compound containing hydrogen, fluorine and carbon atoms 1,1-difluoroetane - C2H4F2). Hydrofluorocarbon was introduced as a safer alternative to chlorofluorocarbons in regard to the ozone layer. It is used mostly as a propellant in aerosol sprays, as a refrigerant, etc.1,1-difluroethane do not pose a danger to the environment (contribution to the greenhouse effect, depletion of the ozone layer, etc.).As discussed in this paper from 1998:Benchang Sangchakr, Teruaki Hisanaga, Keiichi Tanaka, Photocatalytic degradation of 1,1-difluoroethane (HFC - 152a), Chemosphere, Volume 36, Issue 9, April 1998, Pages 1985-1992, ISSN 0045-6535, DOI: 10.1016/S0045-6535(97)10083-2.

What is the impact of aerosol sprays on the atmosphere?

Aerosol sprays used to be powered by CFCs (chlorofluorocarbons), which were destroying the ozone layer. Thanks to the Montreal Agreement, the whole world agreed to stop making CFCs and the ozone layer is now slowly recovering. Scientists hope it will be fully restored by around 2050.


Why were cfcs used in aerosol sprays?

CFCs break down in the upper atmosphere due to UV light from the sun, forming chlorine radicals (chlorine paricles that will react with just about anything). These will collide with ozone, which is a chemical found in the stratosphere that absorbs harmful solar rays, breaking it down into oxygen. This process destroys the naural defenses the earth has against damaging levels of solar radiation. Without ozone, cancers and blindness would affect almost every living creature on earth.
