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.
