How dangerous is propylene glycol containing antifreeze?
Propylene glycol is the main ingredient in “safer” forms of engine antifreeze and is considered to be approximately 3 times less toxic in dogs than ethylene glycol. Automotive antifreeze solutions containing 50% or more propylene glycol are safer than ethylene glycol-containing antifreezes because it will not cause the serious kidney damage that is seen with ethylene glycol toxicosis. However, it is important to remember that ingestion of propylene glycol-containing antifreezes may result in serious intoxication similar to that seen with other types of alcohol, such as ethanol. 4. How dangerous is ethylene glycol containing antifreeze exposure? Ethylene glycol is the most common and the most dangerous form of antifreeze. Ethylene glycol can cause metabolic acidosis and acute renal tubular necrosis. Most commercial antifreeze products contain between 95-97% ethylene glycol. Although the minimum lethal dose of undiluted ethylene glycol antifreeze is 4.4-6.6ml/kg in dogs and 1.4ml/kg in c
