1 Classification of aerosol

Because of the novel packaging and convenient use of aerosol, aerosol is widely used in the field of daily chemical, popular with consumers, common skin care products, hair care products and oral products.

At present, there are two common packing forms of aerosols: one is the filling packing form of mixing the bulk and propellant (single type aerosol), and the other is the filling packing form of separating the bulk and propellant (binary type aerosol).

Aerosol products were produced in the 1930s, first used in medicine, and then gradually used in industry, agriculture, daily chemical supplies and so on. Aerosol means that the contents and propellant are sealed together in a container with a valve and sprayed out in a predetermined form under the pressure of the propellant.
