Merck, 8170029025, Polyethylene glycol

Polyethylene glycol is designed for use as PEG 300 in pharmaceutical formulation across solid, semi-solid, and liquid dosage forms. This product is EMPROVE® EXPERT grade and meets Ph. Eur. and NF requirements. Its functional use can include improving API solubility, serving as a lubricant in tablet-coating applications, and acting as a carrier in formulation systems. The polymer has the general structure H(OCH₂CH₂)nOH and is supplied in a 25 L plastic container. The PEG 300 grade provides a low-molecular-weight liquid polyethylene glycol option for formulations that require a multifunctional polymer rather than a higher-molecular-weight solid PEG. The product is part of a pharmaceutical and biopharmaceutical raw-material portfolio intended for development, scale-up, and production workflows. Its compendial status and EMPROVE® documentation framework support qualification for regulated formulation environments where raw-material traceability and controlled quality are important. The 25 L pack size is suited to manufacturing or scale-up use where PEG 300 is consumed as a formulation component rather than as a small laboratory reagent. The product has Quality Level 500, a vapor pressure below 0.1 hPa at 20 °C, and a linear polyether structure terminating in hydroxyl groups. These characteristics are consistent with the liquid PEG 300 grade supplied for formulation use.
