Usage

General Description

1-ethyl-2,4-dimethyl-1,2-dihydroquinoline, also known as Ethoxyquin, is a synthetic organic compound that is commonly used as an antioxidant in animal feed and pet food to prevent the oxidation of fats. It is a yellowish liquid with a characteristic odor and is generally stable under normal conditions. Ethoxyquin functions by preventing the formation of peroxides in the fats and oils, thereby extending the shelf life of the feed and preventing rancidity. While it is widely used in the animal feed industry, there have been concerns about its potential health risks and regulatory authorities have imposed restrictions on its use in certain countries.
