PEG 8000 (polyethylene glycol 8000)

Polyethylene glycol 8000 (CAS No. 25322-68-3) is a high-molecular-weight PEG supplied as white to off-white flakes or powder. PEG 8000 offers low diol content, higher crystallinity, and excellent stability—supporting pharmaceutical, personal care, and industrial applications.

Pharmaceutical and personal care uses

High molecular weight PEG 8000 functions as a solvent, binder, and film-coating component in oral, topical, and parenteral preparations. It blends with other PEG molecular weights to achieve target melting point and viscosity. PEG 8000 does not support microbial growth in aqueous solutions.

Industrial applications

PEG 8000 is used as a base in soap stick formulations for oilfield applications (see soap stick bases) and as a processing aid in ceramics, rubber, and paper. Soluble in water and alcohols.
