What is PEG 400 used for in pharmaceutical formulations?
PEG 400 is used as a solvent and co-solvent in oral liquids and parenteral formulations, as an ointment and cream base, as a plasticiser in tablet film coatings, and as a component in suppository bases blended with higher molecular weight PEGs. It is also used in some injectable formulations as an approved co-solvent.
Can PEG 400 be used in injectable pharmaceutical formulations?
Yes. USP grade PEG 400 is an approved co-solvent in select parenteral formulations, used to improve solubility of poorly water-soluble drugs. Injectable use requires strict adherence to USP specifications including low peroxide and aldehyde content, and appropriate quality documentation should always be verified for the intended route of administration.
What is the difference between PEG 400 and lower or higher molecular weight PEG grades?
PEG 400 sits between the very low molecular weight liquid PEGs (200, 300) and the semi-solid to solid grades (600 and above). It offers a good balance of solvency, viscosity, and water solubility, making it the most commonly specified liquid PEG in pharmacopoeial monographs and formulation guides.
