What effects does hairspray have on the Ozone Layer?

It is the propellant that gets the airspray out will rise to the atmoshpere, in layman terms, we call it aereosolWhat effects does hairspray have on the Ozone Layer?
the propellant used to be chlorinated hydrocarbons that would damage ozoneWhat effects does hairspray have on the Ozone Layer?
it burns the ozone layer and causes air pollution
NO the ozone layer is very high and CFC are too heavy to get there. The ozone layer is formed at the very edge of space and only a few gases would be light enough to get there.
Hairsprays contain CHLOROFLOUROCARBONS, also known as CFCs. Chlorofluorocarbons (CFC) are haloalkanes with both chlorine and fluorine. They were formerly used widely in industry, for example as refrigerants, propellants, and cleaning solvents. Their use has been regularly prohibited by the Montreal Protocol, because of effects on the ozone layer (see ozone depletion in second paragraph). They also contribute to global warming. They have a global warming potential (GWP), in terms of carbon dioxide equivalence (over a time period of one hundred years) between 6000 and 9800 per kg.











Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total amount of ozone in Earth's stratosphere since around 1980; and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole.





The detailed mechanism by which the polar ozone holes form is different from that for the mid-latitude thinning, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine.[1] The main source of these halogen atoms in the stratosphere is photodissociation of chlorofluorocarbon (CFC) compounds, commonly called freons, and of bromofluorocarbon compounds known as halons. These compounds are transported into the stratosphere after being emitted at the surface. Both ozone depletion mechanisms strengthened as emissions of CFCs and halons increased.





CFCs, halons and other contributory substances are commonly referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (270鈥?15 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol banning the production of CFCs and halons as well as related ozone depleting chemicals such as carbon tetrachloride and trichloroethane (also known as methyl chloroform). It is suspected that a variety of biological consequences such as increases in skin cancer, damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.
