A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Polyethylene glycol 8 (PEG-8) is a low-molecular-weight poly(oxyethylene) polymer averaging eight ethylene oxide units, supplied as a clear, water-soluble liquid. It is used as a humectant, water-soluble solvent, and carrier in formulated systems.
Frequently Asked Questions
What is PEG-8 used for?
Polyethylene glycol 8 (PEG-8) is a low-molecular-weight poly(oxyethylene) liquid used as a humectant, water-soluble solvent and carrier, and viscosity modifier in formulated aqueous systems. It also serves as a hydrophile intermediate for nonionic surfactant derivatives. CAS 9004-53-9.
Is PEG-8 water soluble?
Yes. PEG-8 is a clear, water-soluble liquid of average eight ethylene oxide units, which is why it is used as a humectant and water-soluble carrier in aqueous formulations.
What is the difference between PEG-8 and PEG-400?
Both are polyethylene glycols differentiated by average chain length. PEG-8 averages eight oxyethylene units; PEG-400 refers to an average molecular weight near 400 g/mol. The grade you specify determines viscosity, hygroscopicity, and freezing point, so confirm the target molecular weight when requesting a quote.
What is PEG-8 made from?
PEG-8 is a poly(oxyethylene) polymer built from repeating ethylene oxide units, averaging eight units per chain. Identity is fixed by CAS 9004-53-9 and the nominal molecular weight.
What is the cost of bulk PEG-8?
Bulk pricing depends on grade, volume, and packaging (drums, IBC totes). Request a current quote from RawSource with your target molecular weight and annual volume; a CoA and SDS are provided with each shipment.
