Uses and Applications of Monoethylene Glycol

Monoethyleneglycol or MEG has a wide range of industrial applications due to its unique chemical properties. It is hygroscopic in nature and has the ability to absorb water from the atmosphere. This property makes it useful for applications like dehumidification and dehydration. MEG is used as an antifreeze in automotive radiators and other cooling systems. The freezing point of water is lowered when MEG is mixed with it, allowing the coolant to maintain its liquid state even at sub-zero temperatures.


Monoethylene Glycol also serves as a humectant and emulsifier in cosmetics, pharmaceuticals, food and personal care products. When added to these formulations, it has the property of retaining moisture, thereby preventing the product from drying up.

This allows extending the shelf life of creams, lotions, ointments and other topical applications. MEG is biocompatible and approved by food regulatory authorities for use across different industries.
