Biodiesel is a renewable fuel derived from vegetable oils and animal fats. As a result biodiesel has a tendency to oxidize. A direct consequence is the formation of solids and other undesirables that might clog a fuel filter and /or create damaging deposits.

Eastman has developed an innovative solution, Eastman BioExtend™ to extend the shelf life of biodiesel and slow down the oxidation process. Superior performance at low concentrations—Eastman BioExtend™ antioxidant provides significantly greater performance than other antioxidant solutions at a much lower concentration.
