Diesel Exhaust Fluid (DEF) is 32.5% solution of high-purity urea in de-mineralized water that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of nitrogen oxides (NOx) from the exhaust systems of diesel vehicles in the USA. Diesel Exhaust Fluid (DEF) is clear non-hazardous liquid.  It is not a fuel, nor a fuel additive and needs to be filled into a dedicated Diesel Exhaust Fluid (DEF) tank which is on your diesel vehicle. It is replenished in a similar way to refueling diesel. Should you spill Diesel Exhaust Fluid (DEF) on your hands, simply wash it off with water. - air1.com
