Triethylene glycol, TEG, or triglycol is a colorless odorless viscous liquid with molecular formula HOCH2CH2OCH2CH2OCH2CH2OH. It is used as a plasticizer for vinyl polymers. It is also used in air sanitizer products, such as “Oust”[1] or “Clean and Pure”. When aerosolized it acts as a disinfectant. Glycols are also used as liquid desiccants for natural gas and in air conditioning systems. It is an additive for hydraulic fluids and brake fluids and is used as a base for “smoke machine” fluid in the entertainment industry.
Triethylene Glycol (TEG) is a colorless, odorless, and hygroscopic liquid belonging to the glycol family. It is widely known for its moisture-absorbing properties and is primarily used as a dehydrating agent, particularly in the natural gas and air conditioning industries. TEG is miscible with water and many organic solvents, making it versatile in industrial and chemical applications.
