USP / Technical Grade
Propylene Glycol is a colorless, nearly odorless, viscous liquid with a faintly sweet taste. It is hygroscopic (attracts water) and miscible with water, acetone, and chloroform. Ruvon supplies both USP Grade (for Food/Pharma/Cosmetics) and Technical Grade (for Industrial/Coolant use).
PG is a diol (alcohol with two hydroxyl groups). Its versatility lies in its non-toxicity (USP grade) and its ability to lower the freezing point of water.
