A third type of antioxidant is ter-tiary antioxidants. König says, “Tertiary antioxidants inhibit the formation of catalysts used in the initiation reaction (see Figure 1). They typically have the function of acting as ferrous and non-ferrous metal inhibitors.” An example of a tertiary antioxi-dant is an alkylated diphenylamine
