    Product Description

    Ethoxyquin dimer is an antioxidant and metabolite of ethoxyquin (Item No. 23094).1 It prevents oxidation of polyunsaturated fatty acids in fish meal and fish oil. Dietary administration of ethoxyquin dimer (0.1, 0.3, and 0.5% w/w) induces microvesicular steatosis and hepatocyte necrosis, as well as increases liver levels of oxidized glutathione and total lipids in mice.2

    WARNING This product is not for human or veterinary use.
