Ethylene Glycol vs. Polyethylene Glycol: Know the Difference
By Shumaila Saeed || Published on December 31, 2023
Ethylene Glycol is a toxic organic compound used as an antifreeze, while Polyethylene Glycol is a non-toxic polymer used in pharmaceuticals and cosmetics.
Key Differences
Ethylene Glycol, a simple diol, is primarily used in antifreeze and coolant solutions due to its low freezing point. Polyethylene Glycol (PEG), a polyether compound, is used in medical applications, lubricants, and personal care products for its solubility and non-toxicity.
