What is Propylene Glycol?
Propylene Glycol (PG), chemically known as 1,2-Propanediol, is a synthetic, colourless, odourless, viscous liquid with the formula C₃H₈O₂. It is a diol (two hydroxyl groups) with excellent hygroscopic, solvent, and humectant properties. Propylene Glycol is classified as GRAS (Generally Recognised as Safe) by the FDA and is one of the most widely used chemicals across the food, pharmaceutical, cosmetic, and industrial sectors.
Polychem Industries supplies Propylene Glycol in USP/Food Grade and Technical Grade to pharmaceutical manufacturers, food processors, cosmetic formulators, and industrial chemical companies across India and internationally. Its excellent safety profile, wide liquid range, and versatility as a solvent and humectant make it indispensable across multiple industries.
