TEA, an organic compound, named N, N-diethylethanolamine under the International Union of Pure and Applied Chemistry (IUPAC), is a colorless, transparent liquid with a strong ammonia odor, and slightly fumes in the air. It is slightly soluble in water and soluble in alcohol and ether. Its aqueous solution is slightly alkaline. TEA is a flammable, explosive, poisonous chemical and strong irritant. It is mainly used as a solvent, a curing agent, a catalyst, a polymerization inhibitor, a preservative, and a synthetic dye in the industry.

TEA is alkaline, reacting with inorganic acids to produce soluble salts. It is flammable and its vapor mixed with air can form an explosive mixture which explodes when exposed to fire or high heat energy. It can react with oxidants. Its vapor is heavier than air, thus it can spread to relatively far places at a lower level. When it encounters fire, it will fuel combustion. What's more, it is a corrosive substance.

TEA can be used as a solvent, catalyst and raw material in the organic synthesis industry. It can be used to prepare the phosgene polycarbonate catalyst, tetrafluoroethylene polymerization inhibitor, rubber vulcanization accelerator, and special solvent for paint removers. It is applied in the enamel anti-hardener, surfactant, antiseptic, bactericide, ion exchange resins, dyes, fragrances, pharmaceuticals, high-energy fuels, and liquid rocket propellants.

Skin contact: One should immediately remove contaminated clothing, flush skin with plenty of running water for at least 15 minutes, and seek medical advice.
Eye contact: One should immediately lift his lids and rinse thoroughly with plenty of running water or saline for at least 15 minutes, and seek medical advice.

Inhalation: One should withdraw quickly from the scene to an area filled with fresh air. Ensure his respiratory tract open. If his breathing worsens, give him oxygen. If his breathing stops, give him artificial respiration immediately. Remember to seek medical advice.
