Preguntas frecuentes
What is polyethylene glycol 4000 (PEG 4000) commonly used for?
PEG 4000 is widely used as a laxative, in pharmaceutical formulations as an excipient (e.g., tablet binder, ointment base), and in industrial applications like lubricants, solvents, and humectants.
What is the chemical formula and molecular weight of PEG 4000?
The chemical formula is **H(OCH₂CH₂)₂�OH**, where *n* averages ~88–92 repeating units. The molecular weight range is **3,800–4,200 g/mol** (nominally 4,000).
How should PEG 4000 be stored?
Store in a tightly sealed container at **ambient temperature (15–30°C)** in a dry, well-ventilated area, away from strong oxidizers or sources of ignition.
What grades of PEG 4000 does Molekula supply?
Molekula supplies **pharmaceutical-grade (EP/USP/JP compliant) and industrial-grade PEG 4000**, with documentation to support your application (e.g., COA, MSDS).
Can Molekula supply PEG 4000 in bulk quantities?
Yes, we offer **bulk packaging options** (e.g., 25 kg drums, 500 kg IBCs) for both pharmaceutical and industrial grades, with flexible MOQs based on your needs.
What documentation is provided with a PEG 4000 order?
Each order includes a **Certificate of Analysis (COA)**, Material Safety Data Sheet (MSDS/SDS), and batch-specific documentation (e.g., stability reports for pharma-grade).
