Diethylene glycol (DEG) is a clear, colorless, and odorless liquid organic compound with the chemical formula (HOCHCH)O. It is a diol, meaning it contains two hydroxyl groups. DEG is miscible with water and many organic solvents. It is commonly used as a solvent, humectant, and plasticizer in various industries, including textile, paper, and cosmetics. DEG is also utilized in the production of polyester resins, polyurethanes, and antifreeze solutions. However, it is important to note that DEG can be toxic if ingested or absorbed through the skin, leading to serious health effects. Therefore, proper handling and safety precautions are essential when working with diethylene glycol
