Triethylene Glycol 101: Chemical Properties, Industrial Applications, and More

Triethylene Glycol, also known as TEG, is a popular compound in various industries for its versatile chemical properties, which allow it to be used in different industrial applications as a mandatory ingredient, such as solvents, hygroscopic agents, humectants, and much more. For instance, it is widely applied in air conditioning systems as a coolant, in the textile and cosmetic industries as raw materials, or in the production of resins. 

In today’s blog, we will discuss TEG’s chemical properties, industrial uses, and much more. Let’s begin.

Applications of Triethylene Glycol

TEG (C6H14O4) is colorless and odorless with a viscous consistency, composed of three ethylene glycol units, giving it diverse chemical properties, including:

  • Solvent Properties: Triethylene Glycol has solvent properties at a moderate level to dissolve various polar and non-polar compounds. Its uses are found in various industrial applications, from textiles to pharmaceuticals to paints, as dyes, resins, or oils. 
  • Hygroscopic Nature: TEG is highly hygroscopic due to its strong affinity for water. It means that this chemical compound can absorb moisture from the surrounding atmosphere. With such chemical properties, its uses as an ingredient in humidity control systems or desiccants are wide. 
  • Low Volatility: Triethylene Glycol is less volatile than other glycols due to its relatively low vapor pressure. This chemical property makes TEG appropriate for industrial applications where the formulation demands low volatility, such as heat transfer fluid or antifreeze.

Diverse Triethylene Glycol properties make TEG a widely used compound for various industrial applications. Here are some we would like to mention:

Dehydration agent

As mentioned, TEG has a high hygroscopic nature, making it perfect for use as a dehydration agent in the natural gas processing industry. It eliminates the moisture from natural gas streams to prevent ice formation, which can interrupt the workflow and damage pipelines. Also, its uses are found in desiccant and humidity control systems due to its hygroscopic properties.

Industrial heating and cooling systems

Due to its low volatility, Triethylene Glycol is commonly used in industrial heating and cooling systems as a heat transfer fluid. This compound has a high boiling point and a low freezing point, making it an appropriate and effective medium to dissipate and absorb heat in HVAC systems. In refrigeration and air conditioning applications, TEG’s uses are also wide because of its hygroscopic nature, making it perfect for controlling moisture in refrigerants, maintaining efficient performance, and preventing corrosion. 


TEG has a wide application in the pharmaceutical sector as a solvent and stabilizer in its liquid formations, for example, in oral suspensions and cough syrups, to enhance the solubility and palatability of active ingredients in medications. 

However, its uses are not limited to the applications mentioned above. There are more:

  • Used as a solvent for rubber, grease, resin, nitrocellulose, pesticides, paint, etc.
  • Used as an ester plasticizer for glass fiber, polyvinyl, PVC, etc.
  • Used as an anti-drying agent for fiber lubricant, tobacco, and desiccant for natural gases
  • Used as a great substitute for diethylene glycol

Safety Considerations for Triethylene Glycol Industrial Applications

When using TEG for industrial applications, as mentioned, it is important to consider safety factors such as proper handling and storage, regulatory compliance, and more. Let us tell you how:

  • Remember to store Triethylene Glycol in a well-ventilated and cool area and follow proper handling guidance when working with this compound.
  • Whether you are a Triethylene Glycol manufacturer or user, always follow regulatory compliance, including application guidelines and rules for waste management and occupational exposure limits. 
  • Use appropriate personal protective equipment (PPE) to avoid direct inhalation of vapors and skin contact.
