DME, or Dimethyl Ether (chemical formula: CH3-O-CH3) is a clear colorless, nontoxic environmentally benign compound that is currently used commercially as a propellant for various aerosol products including perfumes, hair spray and other health products. DME is used in over
10 billion aerosol cans, primarily in Western Europe and North America.
In the atmosphere, Dimethyl Ether has a half life of one day and quickly decomposes to CO2 and water. Dimethyl Ether is neither a carcinogen, a teratogen, nor a mutagen. When it decomposes, it does not lead to formaldehyde formation.
