The German biodiesel quality management association AGQM started a new test round of biodiesel oxidation stabilizers. The sophisticated tests aim at eliminating possible detrimental interactions of additives when blended with diesel fuel.

The use of oxidation stabilizers is highly recommended for B7, which is the reason why today in almost all cases already producers blend biodiesel with oxidation stabilizers. It is necessary to make sure that dosing of additives continues to guarantee a safe application of the end product.

The no-harm test developed by AGQM in cooperation with the mineral oil industry is intended to safeguard that no impairment of the fuel itself or impermissible interaction with other fuel components need be feared. In addition, tests are carried out concerning the relative efficiency to be able to best adapt the use of additives in the individual case with regard to economic aspects also.

The no-harm list published on AGQM’s homepage lists all 42 oxidation stabilizers successfully tested so far. A report of all current test results (made anonymous) is available from AGQM’s Berlin office.  

Both nationally and internationally AGQM offers a concept of measures for the quality assurance of biodiesel that comprises the entire production and marketing chain. The association is involved in research projects for most diverse application options of biodiesel and its byproducts.
