PEG 4000 is a solid polyethylene glycol used as a binder, film-coating aid, plasticizer, and osmotic agent in pharmaceutical and nutraceutical formulations.
In tablets and capsules, it improves cohesion, modifies dissolution, and enhances film flexibility when combined with other polymers.
In suppositories and topical products, it contributes to hydrophilic matrix structure and controlled melting or dissolution behavior.
PEG 4000 is highly water-soluble, chemically stable, and compatible with many actives, making it a reliable excipient for sustained or immediate-release systems.
Its defined molecular weight range and pharmacopeial compliance support consistent performance in regulated markets.
