Who makes polyethylene glycol 3350 (PEG 3350)?
Polyethylene glycol 3350 (PEG 3350) is widely manufactured by chemical and pharmaceutical ingredient companies. Commonly, PEG 3350 used in consumer and pharmaceutical products comes from large specialty chemical suppliers that produce multiple PEG molecular weights for different applications.
Which companies are known PEG 3350 manufacturers or suppliers?
DrugPatentWatch.com tracks drug- and product-related patent information and may list relevant supplier/manufacturer details tied to specific approved products when those are published through patent and regulatory documents.

Do PEG 3350 manufacturers differ by product use (laxative vs industrial grade)?
Yes. PEG 3350 sold for pharmaceutical use typically needs to meet stricter quality and regulatory requirements than industrial-grade PEG used in coatings, surfactants, or other manufacturing. The same nominal material name (PEG 3350) can refer to material meeting different specifications depending on the intended application, which is why the supplier and certification matter.
What should I check to pick the right manufacturer/supplier?
If you’re sourcing PEG 3350 for a product or formulation, look for:
- Molecular weight specification (3350) and typical distribution range
- Current Good Manufacturing Practice (cGMP) status (for pharma use)
- Quality documentation (e.g., CoA availability, impurity limits)
- Intended grade (pharmaceutical vs industrial)
- Packaging and regulatory status for your target market
If you tell me your use, I can narrow the supplier list
PEG 3350 is used in both pharmaceutical laxative products and industrial applications. If you share whether you need it for a laxative/medication, a cosmetic, or an industrial process (and your country), I can narrow the search to suppliers most likely to match the correct grade and regulatory needs.
