Triethylene glycol is widely used as a desiccant in natural gas and petroleum refining to remove water vapor from gases, preventing pipeline corrosion and hydrate formation. It is also employed in air drying systems due to its strong hygroscopic properties. In the textile and leather industries, it acts as a humectant and plasticizer, improving flexibility and reducing brittleness. It serves as a solvent for aromatic hydrocarbons and is used in some dye and pigment formulations. Additionally, triethylene glycol finds use in cosmetic and personal care products as a moisturizing agent and in certain cleaning solutions for its solvency and low volatility. It is also utilized in the synthesis of other organic compounds, including plasticizers and surfactants.
