Propylene glycol USP/EP: Pharmaceutical grade

Propylene glicol is a light, transparent liquid, almost odorless and with low volatility. It is completely soluble in water and in most organic solvents. In addition, all propylene glycols have a great capacity to hold and dissolve active ingredients equally which allows them to serve as carriers of aromas, flavours, dyes and moisture.
