    • Applications: Used in oral liquids, injectables (requiring high-purity pharmaceutical grade), topical ointments, and creams. It is a common excipient.
Industrial Applications:
    • Antifreeze and Heat Transfer Fluid: Due to its low freezing point, it’s used in automotive antifreeze, aircraft deicing fluids, and solar thermal systems. It is less toxic and more environmentally friendly than ethylene glycol.
    • Unsaturated Polyester Resin (UPR): A key raw material for producing UPR, which is used to make fiberglass-reinforced plastics (FRP) for automotive parts, bathtubs, tanks, etc.
