What are Glycols?

In a glycol molecule, two hydroxyl (-OH) groups are attached to different carbon atoms. The most common and simple types of glycols are mono ethylene glycol (C2H6O2) and mono propylene glycol (C3H8O2).

Common Types of Glycols

Mono Ethylene Glycol

Mono ethylene glycol (MEG) is a slightly viscous liquid with a clear, colourless appearance and virtually no odour. The primary use of MEG is as a polymer precursor in the plastic industry, where it can be used to manufacture PET which is used in plastic bottles and microwaveable containers. It is also used in antifreeze due to its ability to reduce the freezing temperature of water.

Mono Propylene Glycol

Mono propylene glycol (MPG) is soluble in water and has hygroscopic properties, meaning it can absorb water from the air. MPG is often produced in two different grades to meet various industry and consumer needs. Due to its freezing point lowering by mixing with water, it is used as an antifreeze and aircraft de-icer. For consumer uses, it is used in food colourings, flavourings, and moderating moisture in food in addition to in the cosmetics industry.

Di Propylene Glycol

Di propylene glycol (DPG) is fully miscible in water and many other organic components. It also has a low toxicity and evaporation rate making it useful as an intermediate in a range of industries. A key use of DPG is in the production of plasticisers as well as many uses as a solvent such as for printing inks and insecticides. A fragrance grade of the chemical can be used in the cosmetic industry to carry the fragrance in perfumes.

Triethylene Glycol

Triethylene glycol (TEG) is a colourless and non-volatile liquid that is known for its hygroscopic properties. In the oil and gas industry, it removes water from the gas before being condensed in the pipelines, preventing the gas from freezing. With its low toxicity, antimicrobial properties, and low odour, it is ideal as a mild disinfectant and as a dehumidifying agent in air-conditioners.
