LANXESS has been awarded "no-harm certification" from Arbeitsgemeinschaft Qualitätsmanagement Biodiesel e.V. (AGQM) for its new biodiesel stabilizer Baynox Solution 50%. Working closely with oil corporations in Germany, AGQM (a German consortium for biodiesel quality management) investigated the undesirable side-effects of mixing antioxidants for biodiesel with brand-name diesel and their behavior in combustion engines. The LANXESS antioxidant concentrate passed the numerous tests without any restrictions and has been included by AGQM in the no-harm list.
The effective antioxidant Baynox ensures the biofuel obtained from natural raw material remains stable and can therefore be used for longer. The disadvantage of biofuel is that the unsaturated fatty acid structures easily oxidize in contact with atmospheric oxygen. The oxidation of oils and fats through atmospheric oxygen is known as rancidity. Heat, light and other stress factors accelerate this process, making the oil rancid within a short time. The consequences of this oxidation are, on the one hand, a decomposition of the biodiesel into short-chained fatty acids and, on the other, the formation of insoluble polymers (gums). This can cause damage to the engine and the injection system.
