17 Eurotiox ®, the most cost-effective antioxidant Triple Mode of Action EUROTIOX 1.Citric acid forms reversible bonds with metal pro-oxidants in the premix and feed to inhibit them from initiating oxidation 2. Ethoxyquin blocks oxidation by donating hydrogen ions to free and peroxy radicals formed during the onset and propagation stages 3. Propyl gallate restores and potentiates ethoxyquin activity up to 3 times by donating hydrogen ions from its 3 active sites to oxidised (spent) ethoxyquin molecules
