Glycol vs. Glyoxal: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 11, 2024
Glycol is a type of alcohol with two hydroxyl groups, commonly used as antifreeze; glyoxal is an organic compound with two aldehyde groups, used in textiles and polymers.

Key Differences

Glycol, specifically ethylene glycol, is a type of diol or dihydric alcohol with two hydroxyl (-OH) groups. Glyoxal, on the other hand, is an organic compound characterized by two aldehyde (-CHO) groups.

In industrial applications, glycols are widely used as antifreeze agents due to their low freezing points. Glyoxal finds its applications in textile and polymer industries as a crosslinking agent due to its reactive aldehyde groups.
