Triethylene Glycol (TEG)

Triethylene Glycol (TEG) is a chemical compound that belongs to the group of glycols. It is a diol (two hydroxyl groups, -OH), consisting of three ethylene units (C2H4O) connected together. Triethylene glycol has the chemical formula C6H14O4 and is a viscous, odorless liquid with a mild sweet taste.

Properties:

• Physical form: Colorless, viscous liquid
• Odor: Mild or almost odorless
• Solubility: Soluble in water, alcohol, and most solvents
• Toxicity: Generally considered to be of low toxicity, but should be used with caution in high concentrations.

Where is Triethylene Glycol Used?
Triethylene glycol has a wide range of applications, both in industrial processes and consumer products. Some of the most common uses include:

• As a solvent: Triethylene glycol (TEG) is used as a solvent in many industrial applications. It dissolves a wide range of organic substances and is therefore used in the manufacture of dyes, chemicals, and cleaning products.
• In moisturizers: Triethylene glycol (TEG) is also used in cosmetics and skincare products as a humectant. It helps to retain moisture in the skin and can be found in products like creams, lotions, and deodorants.
• In antifreeze and coolants: Due to its lower freezing point (it freezes at -10°C), triethylene glycol is used as an antifreeze and in coolants, for example, in car cooling systems, hydraulic systems, and industrial cooling systems.
• In the aerospace industry: TEG is an important component in airlines' anti-icing systems (preventing ice formation on aircraft). It is used in frost protection and in certain aircraft fuels.
• In plastic and rubber production: It is used in the production of polyesters and other polymers, where it can function as a plasticizer and stabilizer. It improves the flexibility and durability of plastic materials.
• In pharmaceutical products: Triethylene glycol is also used in pharmaceutical preparations as a solvent or stabilizer in certain medical formulations and injections.

Benefits and Safety
Triethylene glycol is generally considered to be relatively safe, but it should be used with caution in industrial processes. Although it is not highly toxic, it may cause irritation upon contact with skin or eyes. In higher concentrations, it can have mild toxic effects, especially if ingested.

In cosmetics and pharmaceutical products, it is used in safe concentrations and is approved by authorities such as the FDA and EFSA for use in certain products.

Summary
Triethylene glycol (TEG) is a glycol with many applications. It is used as a solvent, humectant, antifreeze, and as a component in various industrial processes. It is a relatively safe and versatile substance but should still be used with caution in the proper concentrations.

 

Triethylene glycol (TEG) can be supplied in bulk, IBC, drums, and cans.
