Diethylene Glycol Uses: Where DEG Goes
Most diethylene glycol is consumed as a chemical building block, not as a finished product. These are the main uses our buyers supply into.
Unsaturated polyester resins (UPR)
The largest use. DEG reacts with maleic and phthalic anhydride to make flexible, tough unsaturated polyester resins for fibreglass boats, pipes, tanks, panels and cultured marble.
Polyester polyols and polyurethanes
DEG is a diol in polyester polyols for polyurethane foams, coatings, adhesives and elastomers, and a chain extender in some polyurethane systems.
Plasticisers and morpholine
DEG is esterified to make plasticisers such as DEG dibenzoate for PVC and adhesives, and it is the feedstock for morpholine, a corrosion inhibitor and rubber chemical.
Natural gas dehydration
Gas plants use glycols to absorb water from natural gas and prevent hydrates. DEG is used in some units, while triethylene glycol (TEG) is the standard dehydration glycol.
Antifreeze and heat-transfer blends
DEG is blended with monoethylene glycol in some antifreeze, coolant and heat-transfer formulations. MEG remains the main antifreeze glycol.
Solvent, humectant and grinding aid
DEG is a solvent and moisture-retaining agent in printing inks, dyes, textile and leather lubricants, paper and adhesives, and a grinding aid in cement mills.
Industrial use only. Diethylene glycol is toxic if swallowed and must never be used in medicines, syrups, food, beverages, toothpaste or other products for oral use. Contamination of medicines with DEG has caused fatal poisonings. We supply industrial-grade DEG only and do not sell it for pharmaceutical, food or cosmetic use.
DEG vs MEG vs TEG vs MPG: Which Glycol Do You Need?
Buyers often compare diethylene glycol with the other glycols we supply. They behave differently and are not interchangeable without checking your process.
| Glycol | Boiling point | Main uses | Note |
|---|---|---|---|
| MEG (monoethylene glycol) | 197 °C | PET fibre and resin, antifreeze | Main product of ethylene oxide hydration |
| DEG (diethylene glycol) | 245 °C | Polyester resins, polyols, plasticisers, solvents | Co-product of MEG; harmful if swallowed |
| TEG (triethylene glycol) | 285 °C | Natural gas dehydration, plasticisers | Lowest volatility of the three ethylene glycols |
| MPG (monopropylene glycol) | 188 °C | Resins, food, pharma and cosmetics (USP grade) | Low toxicity; made from propylene oxide |

Diethylene Glycol Packing and Container Loading
| Packing | Net weight | Per 20ft container | Best for |
|---|---|---|---|
| HDPE drum | 200 or 250 kg | About 80 drums (16–20 MT) | Distributors and smaller plants |
| IBC tote | 1,000 kg | 20 IBCs (20 MT) | Mid-size users with forklift handling |
| ISO tank | 21–24 MT | 1 ISO tank | Resin and polyol plants with bulk tanks |

Storage and handling
- Keep it dry: DEG absorbs moisture from the air, so keep drums, IBCs and tanks closed, and use a nitrogen blanket or desiccant breather on bulk tanks.
- Tank materials: stainless steel, aluminium or lined carbon steel tanks and HDPE drums are suitable.
- Temperature: store away from heat and direct sun; DEG freezes at about −10 °C.
- Keep it apart: separate from strong oxidisers and strong acids.
- Protect people: wear gloves and goggles, wash hands after handling, and never eat, drink or smoke in the work area.

Diethylene Glycol Price: What Drives It
There is no exchange-traded benchmark for diethylene glycol, so the DEG price per ton is set contract by contract. These are the factors that move it:
- MEG production rates – DEG is a co-product of MEG, so its supply rises and falls with MEG plant output.
- Ethylene and energy costs – the main cost drivers at the producer.
- Demand from resin and polyol makers – unsaturated polyester resin demand follows construction, marine and automotive activity.
- Packing – drums and IBCs cost more per tonne than ISO tank shipments.
- Freight and route – container and ISO tank freight to your port, and route disruptions, change the delivered price.

Diethylene Glycol Supplier: Frequently Asked Questions
What is diethylene glycol used for?
Diethylene glycol is used mainly to make unsaturated polyester resins, polyester polyols for polyurethanes, plasticisers and morpholine. It is also used in natural gas dehydration, antifreeze and heat-transfer blends, and as a solvent and humectant in inks, dyes, textiles and cement grinding aids.
Is diethylene glycol toxic?
Yes. Diethylene glycol is classified as harmful if swallowed (H302), and swallowing it can cause severe kidney damage and death. It must never be used in medicines, food, beverages or oral-care products. With normal industrial handling, gloves and goggles, it is used safely in resin, polyol and gas plants.
What is the difference between DEG and MEG?
MEG (monoethylene glycol) is the main product of ethylene oxide hydration and is used for PET and antifreeze; it boils at 197 °C. DEG (diethylene glycol) is a co-product with a higher boiling point of 245 °C, used mainly for polyester resins, polyols and plasticisers.
What is the difference between DEG and TEG?
TEG (triethylene glycol) has one more ethylene oxide unit than DEG, a higher boiling point of about 285 °C and lower volatility, which makes it the standard glycol for natural gas dehydration. DEG is cheaper per tonne and is used more in resins, polyols and plasticisers.
Is diethylene glycol the same as ethylene glycol?
No. Ethylene glycol usually means monoethylene glycol (MEG, C₂H₆O₂). Diethylene glycol (C₄H₁₀O₃) is two ethylene glycol units joined by an ether bond, with a higher boiling point and different uses.
What is the CAS number of diethylene glycol?
The CAS number of diethylene glycol is 111-46-6. Its EC number is 203-872-2, its formula is C₄H₁₀O₃ and its molar mass is 106.12 g/mol.
What is the HS code for diethylene glycol?
Diethylene glycol is classified under HS code 2909.41, 2,2′-oxydiethanol (diethylene glycol, digol). Countries add their own national digits to this six-digit code.
What is the density of diethylene glycol?
The density of diethylene glycol is about 1.118 g/cm³ at 20 °C, so one litre weighs about 1.12 kg and 1,000 litres weigh about 1.12 metric tons.
What is the boiling point and freezing point of DEG?
Diethylene glycol boils at 245 °C (473 °F) and freezes at about −10.4 °C (13 °F). Its closed-cup flash point is 124 °C.
Is diethylene glycol soluble in water?
Yes. Diethylene glycol is fully miscible with water in all proportions, and also with alcohols, acetone and other glycols. It absorbs moisture from the air, so containers should be kept closed.
Is diethylene glycol flammable?
Diethylene glycol is combustible but not easily ignited: its flash point is 124 °C (closed cup). It is generally not classified as dangerous goods for sea transport, but always follow the SDS for the batch shipped.
Do you provide an SDS (MSDS) for diethylene glycol?
Yes. Every shipment comes with a Safety Data Sheet and a certificate of analysis. The technical data sheet for our DEG can be downloaded on this page.
What is the price of diethylene glycol per ton?
The diethylene glycol price per ton depends on MEG plant output, ethylene and energy costs, packing, quantity and freight to your port. There is no public benchmark, so send your quantity, packing and destination for a dated quotation.
What is the minimum order quantity for DEG?
Our minimum order is one full container load (1 × 20ft FCL): about 80 drums, 20 IBCs or one ISO tank, depending on the packing you choose.
How is bulk diethylene glycol packed and shipped?
We ship DEG in 200 or 250 kg HDPE drums, 1,000 kg IBC totes or 21–24 MT ISO tanks, loaded at Jebel Ali (UAE) or Mersin (Türkiye). Lead time is 7–10 days from order to loading.
Can diethylene glycol be used in cosmetics or medicines?
No. We supply industrial-grade diethylene glycol only. DEG must not be used in medicines, syrups, food, toothpaste or cosmetics; for those uses buyers need pharmaceutical-grade glycols such as USP monopropylene glycol or glycerine from approved sources.
