Propylene Glycol Antifreeze is Far Less Toxic

Propylene Glycol Antifreeze is Far Less Toxic (and Less Tasty)

Ideally, consumers should purchase the far less toxic propylene glycol antifreeze products, which are biodegradable, anti-corrosive, and recyclable, and work just as well as the more highly toxic ethylene glycol antifreeze. Propylene glycol antifreeze is less likely to cause fatal poisoning, and it doesn't taste like candy the way ethylene glycol does, so pets and children are far less likely to consume it.
