Applications:
Due to its unique physicochemical properties, diethylene glycol finds diverse applications across multiple industries:
Automotive and Industrial Coolants: DEG is commonly used as a component in antifreeze formulations because it lowers the freezing point and raises the boiling point of water-based solutions, enhancing their performance in extreme temperatures.
Solvents and Chemical Intermediates: It serves as a solvent in the manufacture of resins, plastics, fibers, and coatings. As a chemical intermediate, it is involved in the synthesis of various esters, ethers, and polymers.
Textile Industry: Employed in the production of polyester fibers and films, where it acts as a reactant with terephthalic acid to form polyethylene terephthalate (PET).
Lubricants and Hydraulic Fluids: DEG enhances the viscosity and lubrication properties of fluids, making them suitable for use in hydraulic systems and as cutting oils.
Pharmaceuticals and Cosmetics: Utilized in the formulation of certain pharmaceuticals and cosmetics due to its humectant properties, which help retain moisture.
Printing Inks and Dyes: Acts as a carrier and stabilizer in printing inks and dye formulations, ensuring even dispersion and adherence to surfaces.
Personal Care Products: Found in various personal care items such as lotions, creams, and shampoos for its moisturizing effects.
It's important to note that while DEG is versatile and widely used, it should be handled with caution as ingestion or prolonged skin contact can be harmful. Appropriate safety measures and regulatory compliance are essential when working with this chemical.
