Propylene Glycol (MPG)

Description

• Propylene glycol is a high-purity, syrup-like liquid that is colorless, odorless, tasteless, synthetic, and fully miscible with water.
• Technical / USP grade antifreeze; propylene glycol is also used as a solvent and humectant in, among others, cosmetics and antifreeze fluids.
• Propylene glycol is not classified as a hazardous substance under Regulation (EC) No 1272/2008 or Directive 67/548/EEC.
• It performs a similar function to ethylene glycol, but its use is preferred due to its lower toxicity.
