Hazards

Reactivity Alerts
Air & Water Reactions
Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979. p.151-154, 164].
Fire Hazard
No information available.
Health Hazard
May cause slight transient (temporary) eye irritation. Corneal injury is unlikely. Prolonged or repeated exposure is not likely to cause significant skin irritation. Repeated prolonged exposure may cause sleepiness. Single prolonged exposure is not likely to result in absorption of harmful amount through skin. Low oral toxicity. Ingestion of large amount may cause injury. Exposure may have anesthetic or narcotic effects. (USCG, 1999)
Reactivity Profile
TRIPROPYLENE GLYCOL METHYL ETHER may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides.
Belongs to the Following Reactive Group(s)
