The CoA doesn't list the following test: Limit of Free Ethylene Oxide and 1,4-Dioxane, Limit of Ethylene Glycol and Diethylene Glycol and Diethylene Glycol, Viscosity, Residual on ignition. Were these tests performed to be qualified as USP/NF/FCC grade?
Hello, and thank yo for your question,
Yes, the tests were performed to qualify the product as USP/NF/FCC grades but were left out due to an error. These test results will be included in the CoA's.

I'm looking for Polyethylene Glycol 400 USP. It seems you only have FCC grade. Can you please tell me if there is a difference? I intend to use it in vaping products.
Currently we offer FCC grade PEG400. USP grade has additional mnonograph requirement which our FCC grade has not been tested.
