Triethylene Glycol (TEG) 99% / 99.5% / >99.9% CAS No. 112-27-6 Industrial & Pharmaceutical Grade

Triethylene Glycol, available in 99%, 99.5%, and >99.9% concentrations, is produced as a co-product during the hydration of ethylene oxide to manufacture ethylene glycol . It features excellent hygroscopicity, a very high boiling point, complete miscibility with water and many polar solvents, and extremely low volatility . As a straight-chain trihydric alcohol with two ether bonds, it is larger than monoethylene glycol (MEG) and diethylene glycol (DEG), resulting in a higher boiling point, density, and viscosity . Its high purity and consistent quality make it ideal for critical applications requiring precise chemical properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial standards .

Scope of Application

• Used as an important non-volatile industrial solvent and a key dehydrating agent in the natural gas industry to remove water vapor from raw natural gas streams due to its hygroscopic nature and high boiling point ;

• Acts as a raw material in the production of polyesters, polyurethanes, plasticizers, and other polymers, improving flexibility and processability ;

• Widely applied in printing inks, varnishes, coatings, and pastes, enhancing flow and leveling properties ;

• Functions as a humectant, solvent, and viscosity modifier in cosmetics and personal care products, such as creams, lotions, and hair care products ;

• Used in the formulation of controlled-release drug delivery systems, improving solubility and bioavailability of drugs, and in the synthesis of polyethylene glycol (PEG)-drug conjugates ;

• Serves as an additive for hydraulic fluids and brake fluids, and as a base for "smoke machine" fluid in the entertainment industry ;

• Acts as a plasticizer for cellophane, glue, cork, powdered ceramics, and some plastics ;

• Utilized in air sanitizer products and for air fumigation, as it acts as a disinfectant when aerosolized .
