关于 Polyethylene Glycol Series

Polyethylene Glycol (PEG), also known as polyethylene oxide (PEO), is a synthetic polymer with the chemical formula H(OCH₂CH₂)ₙOH. PEG is available in a range of molecular weights from low (PEG 200-600, liquids) to high (PEG 1000-20000+, solids), with each grade offering distinct physical properties and applications. It is produced through the polymerization of ethylene oxide with water or ethylene glycol as an initiator. PEG is valued for its water solubility, low toxicity, biocompatibility, and versatility across numerous industries.

Polyethylene Glycol Uses

Pharmaceuticals and Medicine

PEG is extensively used as an excipient in pharmaceutical formulations, serving as a solvent, plasticizer, and tablet binder. It improves drug solubility and bioavailability in oral and topical medications. Higher molecular weight PEGs are used in laxatives (PEG 3350) for treating constipation and in bowel preparation solutions. PEG is employed in drug delivery systems through PEGylation, which attaches PEG chains to proteins and drugs to extend circulation time and reduce immunogenicity.

Personal Care and Cosmetics

In cosmetics and personal care products, PEG functions as a moisturizer, emulsifier, and solvent in creams, lotions, shampoos, and toothpaste. It improves product texture, spreadability, and stability. Lower molecular weight PEGs act as humectants attracting moisture to skin, while higher molecular weights provide structure and consistency. PEG is also used in hair styling products for hold and shine, and in deodorants as a carrier for active ingredients.

Industrial Applications

PEG serves as a plasticizer in adhesives, rubber, and polymer processing, improving flexibility and workability. It is used in metalworking as a lubricant and coolant in cutting and grinding operations. The textile industry employs PEG as a lubricant for fiber processing and as a component in fabric softeners. Additional applications include use in ceramics as a binder, in wood treatment as a stabilizing agent, in inks and coatings as a solvent and dispersant, and in concrete admixtures to improve workability.
