الأسئلة الشائعة
What is polyethylene glycol 400 (PEG 400) commonly used for?
PEG 400 is widely used as a solvent, humectant, and plasticizer in pharmaceuticals, cosmetics, and food products, as well as in industrial applications like lubricants and ointments.
What is the chemical formula and molecular weight of PEG 400?
The chemical formula is **H(OCH₂CH₂)ₙOH**, where *n* averages around 9 (for PEG 400). The molecular weight is approximately **380–420 g/mol** (varies by batch).
How should PEG 400 be stored?
Store PEG 400 in a tightly sealed container at ambient temperature, away from direct sunlight and moisture to prevent degradation.
What grades of PEG 400 does Molekula supply?
Molekula supplies **pharmaceutical-grade (EP/USP), cosmetic-grade (Kosher/ISO), and technical-grade PEG 400**, depending on your application requirements.
Can Molekula supply PEG 400 in bulk quantities?
Yes, we offer PEG 400 in bulk (drums, IBCs, or custom packaging) for industrial and large-scale applications—minimum order quantities vary by grade.
What documentation is provided with a PEG 400 order?
Each order includes a **Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and batch-specific documentation** to ensure compliance with your quality standards.
