Di ethylene glycol (DEG) is a colorless, odorless liquid compound used in various industries, including the Persian chemical industry. It is primarily employed as a solvent for dyes, resins, and other chemicals, making it valuable in the production of paints, inks, and adhesives. DEG is also utilized as a humectant in the textile industry to prevent fiber drying and as a coolant in industrial processes. Additionally, it serves as an ingredient in the manufacturing of polyesters, lubricants, and antifreeze products due to its low freezing point and ability to lower the viscosity of formulations.
