Antioxidant in feed and food; antidegradation agent for rubber. | [Definition]
ChEBI: Ethoxyquin(91-53-2) is a quinoline that is 1,2-dihydroquinoline bearing three methyl substituents at position 2, 2 and 4 as well as an ethoxy substituent at position 6. It has a role as a herbicide, an UDP-glucuronosyltransferase activator, a neuroprotective agent, a Hsp90 inhibitor, a genotoxin, a food antioxidant, a geroprotector and an antifungal agrochemical. It is a member of quinolines and an aromatic ether. | [General Description]
Clear light yellow to dark brown viscous liquid. Discolors and stains badly. Mercaptan-like odor. | [Reactivity Profile]
ETHOXYQUIN(91-53-2) may undergo a hazardous polymerization at temperatures above 320° F. Tends to polymerize and darken in color on exposure to light and air. Not compatible with oxidizing agents and with strong acids . | [Air & Water Reactions]
Polymerizes and darkens in color on exposure to light and air. Insoluble in water. | [Hazard]
Toxic by ingestion. | [Potential Exposure]
Quinoline insecticide, fungicide and
plant growth regulator. Also and ingredient in other products. Used for preharvest or postharvest preservation of
color in apples and pears. It is used as an anti-oxidant to
preserve color in paprika and ground and powdered chili.
Ethoxyquin also is a chemical preservative used in animal
feed to prevent ingredients from reacting with oxygen and
becoming rancid. It has been known to cause birth defects
in pet birds and dogs | [Fire Hazard]
This chemical is combustible. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Give large
quantities of water and induce vomiting. Do not make an
unconscious person vomit | [Shipping]
UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required | [Incompatibilities]
Polymerization can occur on contact
with strong light and/or water. Decomposes in temperatures
above 150℃. Keep away from oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); strong acids. | [Description]
Ethoxyquin is used as an antioxidant in animal feed
and caused contact dermatitis in a worker at an animal
feed mill. | [Waste Disposal]
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.
Consult with environmental regulatory agencies for
guidance on acceptable disposal practices. If allowed,
Incineration with effluent gas scrubbing is recommended.
Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your
regional EPA office | [Agricultural Uses]
Insecticide, Fungicide, Plant growth regulator,
Ingredient in other products: Used for preharvest or postharvest preservation of
color in apples and pears. It is used as an antioxidant to
preserve color in paprika and ground and powdered chili.
Ethoxyquin is also a chemical preservative used in animal
feed to prevent ingredients from reacting with oxygen and
