Frequently asked questions
What molecular weight and hydroxyl value define PEG-4000?
PEG-4000 is specified as a white flake with molecular weight 3600-4400, hydroxyl value 26-32 mgKOH/g, Color (Pt-Co) ≤50 and 1% pH 5.0-7.0. That high MW and low hydroxyl value are what make it a binder, thickener and lubricant rather than a low-MW solubiliser.
Is PEG-4000 available as USP or EP grade?
No USP or EP compliance wording is in the published specification, because our client source does not state USP/EP text and we do not assert it. The product conforms to the enterprise standard Q/320621HA024. For regulated pharma or food use, request the applicable grade certificate so your QA can confirm before use.
Where does the PEG-4000 spec come from?
CAS 25322-68-3 and the spec block are verified against the client manual (PEG series, p36) and the CAS reference (p1). We recommend a lot-specific COA for incoming QC.
How do I handle PEG-4000 flakes in the plant?
It is a white flake, water-soluble. Melting point and moisture are not in the published manual PEG table, so confirm your dissolution temperature against your process and request the TDS for those handling points before scale-up.
What roles does PEG-4000 play across pharma, cosmetic and food?
It is listed as a pharmaceutical excipient (binder, suppository base), cosmetic thickener and lubricant, food-grade processing aid per the applicable grade, and industrial binder, mould-release and tablet-coating auxiliary. For the food- or pharma-grade roles, pair it with the applicable grade certificate as noted above.
