Product Information
DME (Dimethylether = CH3-O-CH3) is a versatile, chemically stable aerosol propellant with a special solvency power for both polar and non-polar ingredients.
DME is an isomer of ethylalcohol and has a low boiling point. It is colourless, virtually odourless, has a low surface tension and a low viscosity.
Owing to its high solubility coefficient, the propellant DME acts also as a solvent in aerosol formulations. This property makes DME a very valuable component in aerosol formulations which contain substances that are difficult to dissolve.
