Biological Activity
The FDA has approved polyethylene glycol (PEG) for use as a vehicle or base in foods, cosmetics and pharmaceuticals, including injectable, topical, rectal and nasal formulations. PEG shows little toxicity, and is eliminated from the body intact by either the kidneys (for PEGs < 30 kDa) or in the faeces (for PEGs > 20 kDa). PEG lacks immunogenicity, and antibodies to PEG are generated in rabbits only if PEG is combined with highly immunogenic proteins[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
