What is Propylene Glycol USP?
Propylene Glycol USP is used as a diluting agent in the production of e-liquids for vaping in e-cigarettes. It is responsible for holding the flavour in the mix. Our PG is a high quality pharmaceutical grade product and conforms with United States Pharmacopoeia (USP).
The most common misconception about Propylene Glycol is that it is a deadly poison commonly found in anti-freeze, wrong! Ethylene Glycol was the culprit in anti-freeze which is now substituted with PG to make it safer!
