Applications: Polyethylene glycol is a high molecular weight polymer characterized by its non-irritating nature and slightly bitter taste. It exhibits excellent water solubility and is compatible with a wide range of organic compounds. Thanks to its outstanding lubricating, moisturizing, dispersing, and adhesive properties, PEG can be used as an antistatic agent and softener. It finds extensive applications in industries such as cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper-making, paints, electroplating, pesticides, metal processing, and food processing.
