Triethylene Glycol (TEG)

Triethylene glycol, commonly known as TEG or triglycol, is a transparent, odorless, and thick fluid. This substance finds its application in softening vinyl-based polymers, acting as a plasticizer. Additionally, TEG is a key component in certain air purifying products like "Oust" or "Clean and Pure." When transformed into an aerosol, it serves as an effective germicide. Glycols have a broader use as moisture-absorbing agents in both natural gas processing and air conditioning systems. Moreover, it's a component in various hydraulic and brake fluids and is utilized as a foundational element for creating fog in the entertainment industry through 'smoke machines'.
