Propylene glycol is technically safer than ethylene glycol. Often used as an additive alternative to ethylene glycol in antifreeze products, it is also found in e-liquids for e-cigarette or vape products and even in human foods. Antifreeze products containing propylene glycol, usually at a concentration of 50% or less, such as SierraTM and Prestone LowTox® are safer than traditional antifreeze and are unpleasantly flavored to prevent ingestion. These safer products will not metabolize into oxalate, but even pet-safe products containing propylene glycol could cause other problems including nervous system injury resulting in incoordination and possibly seizures, along with severe anemia.
