Energy Sector

Triethylene glycol (TEG) is widely used in the natural gas industry as a dehydration agent to remove water vapor from natural gas and other gases. It is also used as a solvent in the chemical industry for the production of resins, inks, and dyes. In addition, TEG is used as a plasticizer for vinyl resins and cellulose-based plastics. It can also be used as a humectant in the food and pharmaceutical industries. TEG has a low volatility and high boiling point, making it an effective and stable compound for a variety of industrial applications.


Triethylene glycol is used in the pharmaceutical industry as a solvent, stabilizer, and excipient in various formulations, such as injectables, ophthalmic solutions, and oral liquids. It is also used as a component in the production of polyethylene glycol (PEG), which is commonly used in the formulation of drugs to improve solubility, bioavailability, and stability. Additionally, TEG is used as a cryoprotectant for the preservation of biological materials, such as cells and tissues, in cryogenic temperatures.
