An inhibitor to prevent oxidative radical degradation catalytically via a benzylic hydrogen abstraction mechanism and/or via an allylic hydrogen abstraction mechanism, effective in an amount of less than 1% (w/w) based on the solid weight of substrate or substrate composition. The inhibitor comprises a conjugated Hückel rule aromatic CH moiety. The aromatic moiety can be selected from benzene, naphthalene, anthracene, phenanthrene or other Hückel aromatic.
