Aerosol Propellants is used with a can or canister that contains a HFA 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. And his product is universally acknowledged as the excellent alternative of CFCs to be used in medicinal aerosol, and we has the certification issued by CFDA in China and also gets DMF certificate from Food and Drug Administration of USA, EDMF in Europe.
