Heavy tails

Heavy tails are a complex mixture of diglycerides and triglycerides from C9 to C18 fatty acids, diglycerides and triglycerides of azelaic acid, and long-chain fatty acids (palmitic, stearic and keto-stearic). The natural use is in biofuels.

There are two grades: IF001M and KF001M, both entirely derived from plant sources and ISCC-EU certified.
