Understanding the scientific principles behind Ethoxyquin (CAS 91-53-2) is key to appreciating its indispensable role in animal feed preservation. At its core, Ethoxyquin functions as a potent synthetic antioxidant. This means it actively combats the process of oxidation, which is a chemical reaction involving the loss of electrons, often triggered by exposure to oxygen, light, heat, or trace metals. In the context of animal feed, fats and oils are particularly susceptible to oxidation, leading to rancidity.

Rancidity not only makes the feed unpalatable but also destroys vital fat-soluble vitamins, such as Vitamins A, D, E, and K, as well as essential fatty acids and pigments like carotenoids. Ethoxyquin works by acting as a radical scavenger. Free radicals are unstable molecules with unpaired electrons that initiate a chain reaction of oxidation. Ethoxyquin effectively donates an electron to these free radicals, stabilizing them and breaking the chain reaction. This process is crucial for maintaining the nutritional integrity and shelf-life of the feed.

The chemical structure of Ethoxyquin, specifically its quinoline base and ethoxy group, contributes to its antioxidant efficacy. As a leading manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Ethoxyquin product is produced to the highest purity standards, maximizing its antioxidant potential. By incorporating Ethoxyquin into feed formulations, manufacturers can significantly extend the stability of their products, ensuring animals receive the full spectrum of nutrients required for optimal health and growth. This scientific application of Ethoxyquin is a testament to its value in modern animal nutrition.
