|An air freshener is an aerosol. It is made from tiny liquid droplets hanging in the air like a mist.
Not all aerosols are so fine. Furniture polish and shaving foam are also aerosols but look and feel very different from the fine mist of the air freshener.
There are many uses of aerosols. And for each use, the makers can vary the properties of the spray. They do this by changing the variables that govern the properties. One example of a variable is droplet size. This affects the way an aerosol feels and works.
