Triethylene Glycol Core Applications
Natural Gas & Petroleum Industry
TEG is widely used as a dehydration agent for natural gas, liquefied petroleum gas (LPG), and hydrocarbon streams. Its strong hygroscopicity enables efficient removal of moisture to meet pipeline transportation standards, preventing hydrate formation and corrosion of equipment. Triethylene Glycol is also utilized in gas sweetening processes to enhance purification efficiency.
Chemical Synthesis
As a key intermediate, Triglycol serves as a raw material for the production of:
Polyester resins, polyurethanes, and plasticizers
Glycol ethers (e.g., triethylene glycol monomethyl ether)
Esters for lubricants and specialty coatings
Surfactants and detergent formulations
Pharmaceutical & Cosmetic Industries
Acts as a humectant in cosmetics, skincare products, and personal care items (e.g., lotions, creams, shampoos) to retain moisture and improve skin feel.
Serves as a solvent and stabilizer in pharmaceutical formulations, including oral medications, topical creams, and drug delivery systems.
Used in food additives (FDA-compliant grades) as a moisture retainer for baked goods and confectionery.
Triethylenglycol Other Industrial Uses
Heat transfer fluid: Employed in closed-loop heating/cooling systems due to its high boiling point and thermal stability.
Textile industry: Functions as a softener, antistatic agent, and dyeing auxiliary to improve fabric quality.
Printing inks: Enhances ink flow, adhesion, and moisture resistance in commercial printing applications.

Triethylene Glycol Handling & Storage Guidelines
Storage: Keep in sealed, corrosion-resistant containers (HDPE, stainless steel) in a cool, dry, and well-ventilated area. Avoid direct sunlight and exposure to high temperatures (store below 30°C).
Handling: Use appropriate personal protective equipment (gloves, goggles, protective clothing) to prevent skin and eye contact. In case of spillage, absorb with inert materials (e.g., sand, vermiculite) and dispose of in accordance with local environmental regulations.
Triethylene Glycol Shelf Life: 24 months from the date of manufacture when stored under recommended conditions.
