Because of cost, the majority of water-based aerosols are most likely dispensed using a hydrocarbon propellant at a 4 to 10% level. Since Dimethyl Ether is soluble in water if over 19% DME is required to dispense the contents, a good corrosion inhibitor must be used because DME will penetrate can linings allowing attack of the tinplate.
