Pentaethylene glycol

Pentaethylene glycol (CAS 4792-15-8 ), also abbreviated as PEG-5, is a mid-chain polyethylene glycol diol used as a humectant, plasticizer, and solvent across pharmaceutical, industrial, and polymer applications. Its defined five-unit ethylene oxide chain makes it a well-characterized building block for formulators requiring a specific molecular weight fraction within the PEG family. In pharmaceutical formulations, PEG-5 functions as a solvent and carrier for active ingredients in topical and semi-solid dosage forms. Polymer and plastics manufacturers incorporate it as a plasticizer. This additive helps to improve flexibility and processability in films and coatings. Textile and leather processing operations use it as a softening agent and humectant to maintain substrate moisture balance. Metalworking fluid formulators include it as a lubricant component and carrier in water-miscible cutting and grinding fluid systems. Pentaethylene glycol is supplied as a clear, viscous liquid. It is available in drum and IBC quantities suited to industrial procurement volumes. It is available in technical and pharmaceutical-grade specifications for various buyers. Buyers typically source against defined purity thresholds relevant to their regulatory requirements. Specification alignment with USP or Ph.Eur. PEG monographs should be confirmed. Consult with the supplier for regulated applications to ensure compliance. This ensures the material meets the necessary standards for your specific industrial or pharmaceutical manufacturing process. Contact us for supply of Pentaethylene glycol Request Quote
