Triethylene glycol

Triethylene glycol

Triethylene glycol (TEG) is a chemical compound with the formula C₆H₁₄O₄. It is a colorless, odorless, and viscous liquid that is used in a variety of applications, including as a plasticizer, solvent, and humectant.

Chemical Properties

Triethylene glycol is part of the glycol family, which includes other compounds such as ethylene glycol and diethylene glycol. It is characterized by its three ethylene oxide units, which give it its name. TEG is miscible with water and many organic solvents, making it a versatile substance in industrial applications.

Applications

Industrial Uses

TEG is widely used in the natural gas industry to dehydrate natural gas. It is also used as a plasticizer in the production of plastics and resins, improving their flexibility and durability. Additionally, TEG serves as a solvent in various chemical processes and formulations.

Medical and Hygienic Uses

In the medical field, TEG is used as a disinfectant and sanitizer due to its ability to kill bacteria and viruses. It is also found in some cosmetic and personal care products as a humectant, helping to retain moisture.

Safety and Handling

Triethylene glycol is generally considered to be of low toxicity, but it can act as an irritant to the skin and eyes. Proper safety measures, such as wearing protective clothing and eye protection, should be taken when handling TEG.
