In the pharmaceutical industry, the selection of excipients plays a vital role in the efficacy, stability, and delivery of active pharmaceutical ingredients (APIs). Polyethylene Glycol (PEG), identified by CAS No. 25322-68-3, is a cornerstone excipient with a broad range of applications, particularly in drug formulation and delivery. As a leading manufacturer and supplier of high-purity chemicals, we provide pharmaceutical-grade PEG to meet the exacting standards of the healthcare sector.

Polyethylene Glycol is a water-soluble, biocompatible, and low-immunogenic polymer widely utilized across various pharmaceutical dosage forms. Its versatility stems from its ability to exist in different molecular weights, influencing its physical state and functionality. Lower molecular weight PEGs (e.g., PEG200, PEG400) are commonly used as solvents or plasticizers, enhancing the solubility and bioavailability of poorly soluble APIs. Higher molecular weight PEGs (e.g., PEG1000, PEG4000, PEG8000) are often employed as binders, thickening agents, or matrices for sustained-release formulations, controlling the rate of drug release and improving patient compliance.

PEG's unique properties make it invaluable in several pharmaceutical applications. It is frequently used in oral medications, topical creams and ointments, ophthalmic solutions, and parenteral injectables. Its low toxicity and non-irritating nature on the skin and mucous membranes make it suitable for a wide range of topical and mucosal applications. Furthermore, PEGylation, the process of covalently attaching PEG chains to drug molecules (especially proteins and peptides), is a critical technique for extending their therapeutic half-life, reducing immunogenicity, and improving their pharmacokinetic profiles. This makes PEG a vital component in the development of advanced biopharmaceuticals.
