Pentaethylene glycol

Pentaethylene glycol (CAS 4792-15-8), also known as pentaglycol, is a polyether diol belonging to the ethylene glycol oligomer series. It carries no assigned E-code and is commercially available at 98%+ purity. It is classified under HS code 29094990 for customs and trade purposes.

In polymer and textile processing, pentaethylene glycol functions as a plasticizer by inserting between polymer chains to reduce intermolecular forces, improving flexibility and workability. In pharmaceutical and personal care formulations, its hydroxyl-rich structure enables it to bind and retain moisture, making it effective as a humectant carrier for active ingredients.

Pentaethylene glycol is supplied as a 98%+ purity liquid grade and falls under REACH regulation, requiring compliant SDS documentation for EU trade. It is not listed under FCC or Ph.Eur. monographs. Standard packaging formats for B2B supply typically include drums and intermediate bulk containers.
