Poly(ethylene glycol) is widely used in pharmaceuticals as a solvent, binder, and lubricant in tablet formulations. It also serves as a base in ointments and suppositories due to its water-soluble and non-irritating properties. In biotechnology, it is employed to precipitate proteins and nucleic acids, aiding in purification processes. Additionally, it is utilized in drug delivery systems to enhance the solubility and stability of therapeutic compounds. In the food industry, it acts as a stabilizer and texture enhancer in products such as ice cream and sauces. In industrial applications, it acts as a surfactant, dispersant, and emulsifier in various products like paints, coatings, and adhesives. Its ability to retain moisture makes it a key ingredient in personal care items such as lotions, creams, and toothpaste. Furthermore, it is used in biomedical research for cell fusion and as a cryoprotectant in the preservation of biological tissues. It is also applied as a coating on medical devices to reduce protein and cell adhesion, thereby minimizing inflammation and infection.
