Ethoxyquin Antioxidant Powder
Pure ethoxyquin (1,2-Dihydro-6-ethoxy-2,2,4-trimethylquinoline) in powder form used primarily as a synthetic antioxidant to prevent oxidation in animal feeds and pet foods. This chemically defined heterocyclic compound with a quinoline ring system falls under HTS 2933.49.10.00 as it matches the specific legal description. It is imported as a separate organic compound for industrial formulation into feed preservatives.
Ethoxyquin 66% Liquid Premix
Ethoxyquin diluted in propylene glycol to 66% concentration, supplied as a liquid premix for easy incorporation into poultry and swine feeds as an oxidation inhibitor. Classified under HTS 2933.49.10.00 per Chapter 29 note (e) as solvent dissolution is necessary for safe transport without rendering it suitable for specific use. The core active remains the chemically defined quinoline compound.
