AdBlue Ingredients: What is AdBlue Made Of?

There are many myths surrounding AdBlue and its ingredients. Some believe that it’s made of pig urine and some believe it’s a highly dangerous liquid: both of which aren’t true.

Adblue is actually a high purity, chemically manufactured solution of high-purity urea (32.5%) and deionised water (67.5%). As the urea solution is mostly water-based, it poses little risk to humans and is not harmful to the environment in any way, nor is the solution flammable or hazardous.

The colourless liquid of Adblue is an essential component of selective catalytic reduction (SCR) technology, which is one of the most effective systems for reducing nitrogen oxide levels in the exhaust fumes generated by diesel engines in vehicles.  

What is High-Purity Urea?

When heated by the SCR catalytic converter, the urea becomes ammonia and reacts with the harmful nitrogen oxide (NOx) to convert into harmless pollutants of nitrogen (N2), water vapour (H2O), and a small amount of carbon dioxide (CO2), all of which are elements that we already breathe in the natural air. The urea in AdBlue is therefore the key element to reducing total fuel consumption of diesel vehicles by around 2-6%, protecting the environment.

What is Deionised Water?

The majority of AdBlue is made up of deionised water which successfully dilutes the urea used in the solution. Deionised water is the purest form and so contains no harmful chemicals or minerals that could react badly with urea. Many people question whether tap water could be used in the solution instead, to dilute it further and therefore increase the quantity, however, tap water actually contains lots of minerals and ions that are harmful to the vehicle exhaust treatment system, and could result in further damage to your vehicle.

Every batch of diesel exhaust fluid we make is independently lab tested and certified so you can guarantee you are receiving the solution in its purest form, and in turn, doing your part to help protect the planet.
