Tetraethylene Glycol

Tetraethylene Glycol (TEG-4) is a multifunctional glycol compound widely used in industrial, consumer, and specialty chemical applications. Known for its excellent solvency, humectant properties, and low volatility, TEG-4 is highly valued in formulations requiring moisture retention, stability, and compatibility with a wide range of organic and inorganic compounds. Its chemical structure makes it particularly effective as a solvent, plasticizer, and intermediate in polymer chemistry, supporting high-performance materials and chemical processing.

In industrial applications, tetraethylene glycol is used in heat transfer fluids, antifreeze formulations, and lubricants, where its high boiling point and thermal stability provide reliable performance under demanding conditions. In consumer and specialty markets, TEG-4 is employed in coatings, adhesives, cosmetics, and pharmaceuticals, serving as a carrier, humectant, and formulation aid. It is also applied in gas dehydration and as a building block in the production of surfactants and esters. With its balance of versatility, performance, and cost-effectiveness, tetraethylene glycol remains a critical raw material across industries including automotive, construction, energy, personal care, and specialty chemical manufacturing.
