Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. This is used with a can or bottle that contains a payload and propellant under pressure. When the container's valve is opened, the payload is forced out of a small hole and emerges as an aerosol or mist. As propellant expands to drive out the payload, only some propellant evaporates inside the can to maintain a constant pressure. Outside the can, the droplets of propellant evaporate rapidly, leaving the payload suspended as very fine particles or droplets.

for what it is used
Aerosol spray is an efficient way to dispense drugs that need to be inhaled in measured doses. For this reason medications for asthma, allergies, and lung conditions such as cystic fibrosis are commonly packaged in aerosol cans.
