Last updated: May 21, 2019

What Does Hexylene Glycol Mean?

Hexylene glycol is chemical substance that is an oily colorless liquid with a mild sweet odor. It is also known as 2-Methylpentane-2,4-diol and has a molecular weight of 118.176 g/mol. It is largely used as a key ingredient of corrosion inhibitor additives.


Corrosionpedia Explains Hexylene Glycol

Hexylene glycol-based corrosion inhibitors are used to protect system metals from corrosion in several ways, including:

  • Modifying the metal's surface by absorption (thereby making it less susceptible to corrosion)
  • Buffering the organic acids that are formed due to oxidation
  • Preventing acidic formation

It is fully functional in glycol-water and glycol-ethanol mixtures.

Key features and benefits of hexylene glycol:

  • Prolongs system metal life by reducing degradation
  • Prevents the formation of sludge deposits
  • Prevents leaks and minimizes maintenance costs
  • Reduces the chances of product losses due to leaks

Proper personal protective equipment such as goggles, lab coats, respirators and gloves should be used when handling hexylene glycol.
