Aerosol spray cans were invented by Lyle David Goodloe and W. N. Sullivan in 1941.
They have freon in them which damages the Ozone Layer
The concepts of aerosol can go back as far as the 1790's. The very first aerosol can was invented in November 23rd, 1927 in Oslo, Norway by a chemical engineer named Erik Rotheim.
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..
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.
The constituent part of a solid aerosol is a particle, as opposed to a droplet in a "liquid" based aerosol. By strictest definition a solid aerosol cannot exist; as an aerosol is a suspension of droplets or particles in a gaseous medium.
Ozone layer
Do you prefer an air freshener that plugs into the wall or one that sprays from an aerosol can? Dad likes antiperspirant in an aerosol can, but I like the solid stick.
Liquefied Petroleum Gas (LPG).
Today propane is used.

These include petroleum jelly, oils, and aerosol sprays.

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.

There are 4 layers of atmosphere. Aerosols are banned for the stratosphere.
