Aerosols can be natural, such as fog, or manufactured, such as smoke.
Aerosols are used in industry in canisters containing a propellant gas to spray paint and insecticides. Consumer aerosols include paints, polishes, perfumes, cleaners, deodorants, shaving cream, and whipped cream. Some medications for respiratory complaints are taken via dosage-controlled aerosols.
