Auxiliary Antioxidant – phosphites, thioesters antioxidant

Auxiliary antioxidant, which synonym name is a secondary antioxidant, react with hydroperoxides to produce non-radical products and are therefore often termed ‘hydroperoxide decomposers. They differ from primary phenols and amines in that they are decomposed by reaction with the hydroperoxide, rather than containing it.

Auxiliary antioxidants contains phosphites, thioesters groups. They are particularly useful in synergistic combinations with primary antioxidants.
