DEF is a non-hazardous solution that is made up of 32.5% urea and 67.5% deionized water. An emissions control liquid required by modern diesel engines, DEF is injected into the exhaust stream downstream of the engine as part of Selective Catalytic Reduction or SCR systems, helping to remove harmful NOx emissions.
