Frequently asked questions
What is polyethylene glycol 3350 (PEG 3350) commonly used for?
PEG 3350 is widely used as a laxative, in pharmaceutical formulations as a tablet excipient, and as a solvent or ointment base in cosmetics and personal care products.
What is the molecular formula and approximate molecular weight of PEG 3350?
The molecular formula is H(OCH₂CH₂)ₙOH, where n ≈ 74 (average). The approximate molecular weight is 3,350 g/mol (based on the average polymer length).
How should PEG 3350 be stored?
Store PEG 3350 in a tightly sealed container at ambient temperature (typically 15–30°C) in a dry, well-ventilated area, away from incompatible substances.
What grades or purity levels of PEG 3350 does Molekula supply?
Molekula supplies pharmaceutical-grade (EP/USP/JP compliant) and food-grade (FDA-compliant) PEG 3350, with typical purity ≥ 99.0%.
Can Molekula supply PEG 3350 in bulk quantities?
Yes, Molekula offers PEG 3350 in bulk (minimum order quantities vary; contact sales for custom packaging options, including drums, totes, or FIBCs).
What documentation is provided with a PEG 3350 order?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and a batch-specific quality report. Additional documentation (e.g., DMF or GMP compliance) is available upon request.
