What is Mono Ethylene Glycol (MEG)?
Mono Ethylene Glycol (MEG) is a clear, colorless, odorless, and slightly viscous liquid with the chemical formula C₂H₆O₂. It is a diol (a molecule with two hydroxyl groups), making it an excellent solvent, coolant, and intermediate for various industrial applications.
MEG is most commonly used as a raw material in the production of polyester fibers and PET plastics, as well as a primary ingredient in antifreeze and coolant formulations. It has low volatility and a high boiling point, making it effective in thermal transfer fluids. It is also used in the textile, paint, adhesive, and printing ink industries due to its solvency and hygroscopic (moisture-attracting) nature.

✅ FAQs:
Q1. Is Mono Ethylene Glycol safe to use in automotive radiators?
Yes, MEG is the primary base in most antifreeze/coolant solutions. It must be diluted as per manufacturer recommendations before use.
Q2. Is MEG the same as Propylene Glycol?
No. While both are glycols, MEG is toxic if ingested, whereas Propylene Glycol is considered food-safe. Use MEG only in industrial applications.
Q3. Can MEG be used in cosmetics?
No. MEG is not safe for cosmetic or pharmaceutical use due to its toxicity if absorbed or ingested.
Q4. What is the difference between MEG and DEG (Diethylene Glycol)?
MEG is a smaller molecule with different thermal and chemical properties. DEG is more viscous and often used in brake fluids and lubricants.
Q5. How should MEG be stored?
Store in tightly sealed containers, away from sunlight, heat sources, acids, and oxidizers. Use only with proper industrial ventilation.
