Polyethylene glycol (PEG) is a synthetic polymer composed of repeating ethylene oxide units, available in a wide range of molecular weights from liquid to solid forms. It is widely used in pharmaceutical delivery systems, cosmetics, lubricants, and industrial processing due to its water solubility, biocompatibility, and non-toxic profile. Engineers select PEG for applications requiring controlled dissolution, viscosity modification, or as a processing aid, and it is often chosen over alternatives when biocompatibility or regulatory approval in food and medical contexts is required.
