General description

1-Methoxy-2-propanol (Propylene glycol methyl ether, PGME), a glycol ether, can be synthesized by reacting propylene oxide with methanol in the presence of ZnMgAl (zinc-magnesium-aluminium) catalysts. Its degradation by microorganisms in different soil types has been investigated. An oral reference dose (RfD) and an inhalation reference concentration (RfC) values of PGME have been obtained from inhalation studies in F344 rats and B6C3F1 mice.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry.Monoethers, especially propylene glycol methyl ether (PGME), are widely used as pollution-free solvents in fine chemical synthesis in pharmaceutical, chemical and cosmetic industries and thus aligns with "Safer Solvents and Auxiliaries".
