Polyethylene Glycol (PEG), a synthetic polymer of ethylene oxide, is a chemical compound celebrated for its exceptional versatility and wide-ranging applicability. Its unique molecular structure, often represented as H−(O−CH2−CH2)n−OH, allows for a spectrum of molecular weights, each conferring distinct physical and chemical properties. This adaptability makes PEG a crucial component in numerous fields, from life sciences to heavy industry. Ningbo Inno Pharmchem Co., Ltd. offers a detailed exploration of these fundamental aspects.

The defining characteristic of PEG is its hydrophilic nature, stemming from the ether linkages that readily form hydrogen bonds with water molecules. This results in excellent water solubility, a property that is inversely proportional to molecular weight. Lower molecular weight PEGs (e.g., PEG 200-600) are typically liquids, while higher molecular weights result in viscous liquids, pastes, or waxy solids (e.g., PEG 1000 and above). Understanding these PEG chemical properties is fundamental to its application.

As a non-ionic surfactant, PEG lowers surface tension and can stabilize emulsions, making it invaluable in formulations where oil and water phases need to be mixed. This surfactant action is key to its utility in cosmetics, pharmaceuticals, and industrial detergents. The performance benefits of PEG as a surfactant are significant.

In the pharmaceutical sector, PEG's biocompatibility and low toxicity profile are paramount. It is used extensively as an excipient, a laxative (often referred to as macrogol), and as a crucial component in advanced drug delivery systems, particularly through PEGylation. The PEG drug delivery capabilities enhance therapeutic efficacy and patient compliance.

Industrially, PEG serves as a lubricant, plasticizer, and solvent. Its lubricating properties are beneficial in textile manufacturing and metalworking. As a solvent, it can dissolve a variety of organic and inorganic compounds. Its role as a plasticizer enhances the flexibility of plastics and resins. These industrial applications of PEG highlight its broad utility.
