It is all about the amount of contamination allowed to what purpose. usp food grade kosher is pretty clean to where the skin protectant grade can be used in makeup but I wouldn't vape it personally. although many do. food grade kosher can easilly be found on the internet for pretty cheap.

is that the usp kosher food grade or is that the skin protectant stuff your only supposed to use externally?
