Frequently Asked Questions
Which formula is used?
The page uses the ChemicalBook and CHEMOS PEG-average formula representation: (C2H4O)nC40H78O5.
Why is there no fixed molecular weight?
DSG-PEG2000 is treated as a PEG-average material in the current record, so the fixed PubChem reference MW is not used as the product specification.
