Products Description of Ethoxyquin CAS#91-53-2

Ethoxyquin is abbreviated as EQ or EMQ, also known as ethoxyquin, and its trade names are Sandoquin, Sandoquin, Hupiling, and Ethoxyquin. A yellow to tan viscous liquid with a special odor. Insoluble in water, soluble in benzene, gasoline, ether, alcohol, carbon tetrachloride, acetone and alkyl dichloride Chemicalbook. It is easy to oxidize under natural light. When exposed to air and oxygen, the color becomes dark brown and the viscosity increases. It should be stored in an airtight container away from light. Darkening of the color of the solution will not affect the use effect. This strain is a synthetic antioxidant with a content of 97.5%. Mainly used as antioxidant in food and feed.

Product Application of Ethoxyquin CAS#91-53-2

Ethoxyquin is generally sprayed on the surface of feed, which can effectively prevent rancidity of oils and protein oxidation in feed, prevent vitamins from deteriorating, and has antioxidant effects. The dosage in feed is 100-150g/kg. If used excessively (adding more than 0.1%), the color of pork fat will darken or turn yellow, affecting the quality of the carcass.

Commonly used commercial preparations are divided into two categories: one is a powder containing 10% to 70% of ethoxyquin, which has stable physical properties, is not slippery, does not flow, is evenly distributed in the feed, and can be evenly mixed with the feed; the other is It is a liquid additive and is divided into two types: water and glycerol as solvents.
