Product overview
What Is Triethylene Glycol (TEG)?
Triethylene glycol (TEG), also called triglycol or 2,2′-(ethylenedioxy)diethanol, is a clear, colourless, nearly odourless and slightly viscous liquid with the formula C₆H₁₄O₄. It is hygroscopic, miscible with water, has a high boiling point of 285 °C and a very low vapour pressure. Those properties make it a stable liquid desiccant, humectant and high-boiling solvent.
TEG is made as a co-product of ethylene glycol production. Ethylene is oxidised to ethylene oxide, which is then hydrated to a mix of monoethylene glycol (MEG), diethylene glycol (DEG), triethylene glycol and heavier glycols. These are then separated by vacuum distillation. Because TEG is a smaller cut of every glycol plant's output, a reliable triethylene glycol supplier with steady access to producers matters more than it does for MEG.

Triethylene Glycol Uses: Where Our TEG Goes
Most of the TEG we ship goes into natural gas dehydration. The rest is spread across humidity control, plasticisers, resins and solvents. These are the main triethylene glycol uses among our buyers:
Natural Gas Dehydration
TEG is the standard liquid desiccant for drying natural gas to pipeline specification. It is regenerated at 200–204 °C and recirculated. TEG gas dehydration guide
HVAC and Liquid-Desiccant Dehumidification
TEG solutions absorb moisture from air in liquid-desiccant air-handling and industrial drying systems.
Plasticisers and Safety-Glass Interlayers
TEG esters are used as plasticisers for vinyl polymers, including the interlayer films used in laminated safety glass.
Unsaturated Polyester and Polyurethane Resins
As a glycol building block, TEG adds flexibility to unsaturated polyester resins, polyols and specialty adhesives.
Solvent and Humectant in Inks and Textiles
TEG slows drying and keeps dyes and inks in solution in printing inks and textile dyeing. TEG for textiles
Heat-Transfer, Hydraulic and Fog Fluids
TEG is used as a high-boiling component in heat-transfer and hydraulic fluid formulations, and as a base for stage fog fluids and air-sanitiser products.
Glycol comparison
TEG vs MEG vs DEG: Which Ethylene Glycol Fits Your Process?
Buyers comparing triethylene glycol suppliers often also need MEG or DEG. The three glycols share a chemistry but behave differently in service. Hygroscopicity falls as the molecule gets longer (MEG > DEG > TEG). TEG still wins in dehydration because it has the lowest vapour losses and survives the highest regeneration temperature.
| Property | TEG | MEG | DEG |
|---|---|---|---|
| CAS number | 112-27-6 | 107-21-1 | 111-46-6 |
| Molecular weight | 150.17 | 62.07 | 106.12 |
| Boiling point | 285 °C | 197 °C | 245 °C |
| Freezing point | −7 °C | −13 °C | −10.5 °C |
| Approx. thermal decomposition | ~206 °C | ~165 °C | ~164 °C |
| Volatility | Lowest | Highest | Medium |
| HS code | 2909.49 | 2905.31 | 2909.41 |
| Main uses | Gas dehydration, dehumidification, plasticisers | PET and polyester fibre, antifreeze, hydrate inhibition | Unsaturated polyester resin, polyurethane, solvents |

Buyer's checklist
How to Choose a Triethylene Glycol Supplier: 7 Checks Before You Buy
TEG is a smaller co-product of every glycol plant. Spot cargoes vary more in quality and availability than MEG does. These seven checks separate a dependable triethylene glycol supplier, one that can deliver the same quality cargo after cargo, from a one-off TEG trader:
- Lot-level COA, not a generic datasheet. Ask for purity, water, colour (APHA), specific gravity and acidity measured on the lot you will receive.
- Purity and lighter glycols. For gas dehydration, specify ≥ 99.5% TEG. Excess MEG or DEG vaporises faster and degrades at lower temperature.
- Water content. TEG is hygroscopic. Water picked up in storage or in a poorly sealed tank becomes extra load on your regenerator.
- Clean, dedicated packaging. ISO tanks and flexitanks should be cleaned and certified for glycol service. For drums, choose new steel drums where appearance and absolute cleanliness matter, or clean used steel drums to save cost on industrial use.
- Complete documents. TDS, MSDS, COA, certificate of origin and the correct HS code (2909.49) avoid customs holds and support tender pre-qualification.
- Realistic logistics. Check the loading port, the transit time to your site and whether the supplier can deliver by road for overland markets.
- One supplier for the whole glycol set. If you also buy MEG, DEG, methanol or amines, consolidating them cuts bookings, paperwork and minimum orders.

Safety & storage
Triethylene Glycol Safety, Storage and Handling
TEG has low acute toxicity and a high flash point, and under EU CLP it is generally not classified as hazardous. It is still an industrial chemical. Avoid swallowing it and avoid eye contact, and always follow the SDS supplied with your lot.
Handling
- Wear chemical-resistant gloves and safety goggles
- Provide ventilation when TEG is heated or misted
- Keep away from strong oxidisers and strong acids
- Contain spills with absorbent material; TEG is water-miscible
Storage
- Closed stainless, lined or clean carbon steel tanks, or sealed steel drums
- Nitrogen-blanket bulk tanks to keep out moisture and oxygen
- Store at about 15–25 °C, away from direct heat and sunlight
- Shelf life ≥ 12 months in sealed original packaging
Spent TEG from gas dehydration can pick up benzene and other hydrocarbons, so dispose of or reclaim it under your local waste rules. Fresh TEG does not carry this issue.

FAQ
Triethylene Glycol Supplier FAQ
What is triethylene glycol used for?
Triethylene glycol (TEG) is mainly used to dehydrate natural gas, where it absorbs water vapour in a contactor and is regenerated and reused. It is also used in liquid-desiccant dehumidification, as a plasticiser intermediate for vinyl polymers and safety-glass interlayers, in unsaturated polyester and polyurethane resins, as a solvent and humectant in inks and textile dyeing, and in heat-transfer, hydraulic and fog fluids.
Is triethylene glycol toxic?
TEG has low acute toxicity and a high flash point, and under EU CLP it is generally not classified as hazardous. It should still not be swallowed or allowed into the eyes. Use gloves and safety goggles when handling it, and follow the SDS supplied with each lot.
Is triethylene glycol the same as ethylene glycol?
No. Triethylene glycol (C₆H₁₄O₄) is a longer molecule made from three ethylene glycol units. Compared with ethylene glycol (MEG), it has a higher boiling point (285 °C vs 197 °C), much lower volatility and lower toxicity, which is why it is used for gas dehydration rather than antifreeze.
What is the difference between TEG, MEG and DEG?
MEG, DEG and TEG are one, two and three ethylene glycol units long. MEG is the most volatile and most hygroscopic, and it is used for PET, polyester fibre and antifreeze. DEG is used in polyester resins and solvents. TEG has the lowest volatility and the highest decomposition temperature (about 206 °C), which makes it the standard for natural gas dehydration.
Why is TEG used for natural gas dehydration?
TEG absorbs water strongly, has a high boiling point and can be regenerated at 200–204 °C without breaking down. This lets a dehydration unit reach 98.5–99.9% lean glycol purity with low glycol losses. The U.S. EPA notes that most dehydrators in the industry use TEG.
What purity of triethylene glycol do you supply?
We supply industrial and dehydration-grade TEG at 99.5% minimum purity (99.8% typical), clear and colourless. Water, colour (APHA), specific gravity and acidity are reported on the certificate of analysis for each lot.
What is the CAS number and HS code of triethylene glycol?
Triethylene glycol has CAS number 112-27-6 and EC (EINECS) number 203-953-2. It is generally classified under HS code 2909.49 and is not classified as dangerous goods for transport.
What is the minimum order quantity for TEG?
Our MOQ is 20 MT for bulk shipments in an ISO tank or flexitank, or one full 20ft container of steel drums or IBCs.
How is triethylene glycol packed for export?
TEG is shipped in 22–24 MT ISO tanks, 20–24 MT flexitanks, 1,000–1,100 kg IBC totes, or steel drums. We can ship TEG in new steel drums or, at a lower cost, in clean used steel drums.
Where do you ship triethylene glycol from?
We load TEG FOB Mersin (Türkiye) or FOB Jebel Ali (UAE), with CFR, CIF and DAP terms available. Overland markets such as Iraq, the Caucasus, Central Asia and Europe can be supplied by truck from Türkiye.
What documents come with a TEG shipment?
Each shipment includes a lot-level certificate of analysis, safety data sheet, commercial invoice, packing list, bill of lading or CMR, and certificate of origin. A technical data sheet is available for tender pre-qualification.
How should triethylene glycol be stored?
Store TEG in closed stainless, lined or clean carbon steel tanks or sealed steel drums at about 15–25 °C, ideally under a nitrogen blanket. TEG is hygroscopic, so keep containers sealed to stop it absorbing moisture. Shelf life is at least 12 months in sealed packaging.
Is triethylene glycol hygroscopic?
Yes. TEG readily absorbs water from air and gas, which is why it works as a liquid desiccant. MEG and DEG are even more hygroscopic, but TEG is preferred for dehydration because of its much lower volatility and higher thermal stability.
Can triethylene glycol be regenerated and reused?
Yes. In gas dehydration and dehumidification, TEG is continuously regenerated by heating it to drive off absorbed water, then reused. Fresh TEG is only needed to replace losses and for periodic change-outs.
What affects the price of triethylene glycol?
TEG prices follow ethylene and MEG markets, the operating rates of glycol plants (TEG is a co-product), freight and packaging. Bulk ISO tanks and flexitanks cost less per tonne than drums. Contact us with your volume, packaging and destination for a current FOB or CIF quote.
