1. A method for the production of oxidation-stabilized biodiesel, the method comprising mixing biodiesel with 0.005 to 0.5% by weight of a composition comprising:
A) 40-60% by weight of a mixture of at least one C1-C4-alkylated mono-phenol and at least one C1-C4-alkylated bisphenol, B) 1-5% by weight of a chelating agent for copper and zinc ions, and C) 35-59% by weight of solvent selected from the group of aprotic amides with a chain length of C2-C4 and/or cyclic ketals and/or dibasic esters with a chain length of C4-C5,where a sum of the constituents A), B) and C) is 100% by weight.
