Soft CFC's, they added hydrogen to the CFC's previously used that were called hard CFC's. By doing this it won't allow the CFC's to travel up to the stratosphere, where it breaks down the ozone. With the added hydrogen will stop it in the troposphere and combine to form compounds such as CO2 + HCl (or HF), therefore not harmful to the ozone.
Examples CH2Cl (HCFC-22) or CHCl2-CF2 (HCFC-123)
CFC's as we know are ODS. For this purpose HCFC's were introduced in market.
CFC's are used in refrigerators. One of a CFC is R-12.
Its used in the compressors of refrigerators and air- conditioners
CFC's are used in refrigerators. They are extremely harmful for ozone layer.
the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer
CFC's are chlorofluorocarbons. They are made in industry for the use of refrigeration. Firstly they were thought of miracle compounds. But in 1985 everything changed when Dr. Farman and Dr. Mario Molina discovered that there is a hole in the layer of earth protecting us from the harmful UV radiation. The hole was due to these CFC's only. What these CFC's do is that are carried by westerly's to the poles. Due to the low temperature, they take polar stratospheric clouds as the base or catalysts and perform depletion. They decompose the ozone to form their oxide and that oxide again decomposes to form the original element. This is a chain reaction. A single CFC molecule can destroy over 100,000 molecules of ozone. The main sources of CFC's in day to day life are:DeodorantsAir Conditioners'Aerosol CansSpray CansVehicles Exhaust.

CFC's are mainly there in refrigerators only. They act as cooling agent i.e. they perform the main work.
The compound used in older refrigerators was Chloroflurocarbons which is commomly called as CFC's and the recent ones uses compounds of florides and Hydroflurocarbons which is commonly called as HFC's. CFC's are replaced by HFC's due to their reactivity with the Ozone layer and causes depletion. Hope this helps.
Nowadays we have alternatives for CFC's. These are called HCFC's.
Ozone depletion is due to CFC's. These CFC's are released from refrigerators.
CFC's have uses in household as well. It is used in deodorant, refrigerators, air conditioners, aerosol sprays etc.
I THINK there is a ban on CFC refrigerators in many countries already.
In the past the chemical CFC (chlorofluorocarbons) was used in refrigerators however a few decades ago it was phased out
