|The definition of an aerosol is: |
A collection of tiny solid particles or liquid droplets that are finely dispersed in a gas.
So really, the aerosol is what comes out of the can rather than the can itself. However, when we talk about consumer aerosols, we mean a product in a pressurised container. So the word 'aerosol' has come to have two meanings: the everyday meaning and the technical meaning.
