Ethoxyquin
6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline. Antioxidant; also a post-harvest dip to prevent scald on apples and pears.
Originally developed by Monsanto as a stabilizer for rubber, Ethoxyquin has also been used as a pesticide for fruit and a color preservative for spices, and later for animal feed. The original FDA permit for use as stabilizer in animal feed limited use to two years and did not include pet food, but it falls under the same legal category. It has never been proven to be safe for the lifespan of a companion animal.It has been linked to thyroid, kidney, reproductive and immune related illnesses as well as cancer, but so far no conclusive, reliable research results either for the safety of this product or against it have not been obtained. Monsanto conducted research years ago, but results were so inconclusive due to unprofessional conduct and documentation that the FDA demanded another study. There are currently several studies underway to determine whether Ethoxyquin is safe or not, and until those studies are completed, pet food suppliers may continue to use Ethoxyquin. This is how things stand after about 6 years, and no new details have emerged so far.
