Super Refined™ Propylene Glycol

Super Refined Propylene Glycol is a highly purified propylene glycol that finds application as a solvent, stablilising agent, water-miscible cosolvent, plasticiser, humectant, disinfectant and antimicrobial preservative.  Standard propylene glycol tends to oxidise to form propionaldehyde, lactic acid, pyruvic acid and acetic aldehyde. The act of Super Refining minimises the impurities which accelerate the oxidation of propylene glycol without altering its chemical structure, reducing excipient-API interaction and subsequent degradation. Super Refined Propylene Glycol is designed to provide the highest level of purity of propylene glycol in formulations containing sensitive active ingredients where maximum excipient purity is needed.
