PG (Propylene Glycol)
Propylene Glycol is, along with Vegetable Glycerin, one of the two main base liquids for e-liquid. It is used as a carrier for flavour concentrates, and provides the 'throat-hit' experienced when vaping. The proportion of e-liquid which is PG varies, but the most commmon formulations contain 30 to 50% PG.
Our Propylene Glycol is USP/EP pharmaceutical grade with a purity of greater than 99.9%.
