Re: Antifreeze History?
I'm surprised after the sweetness comments no one mentioned this...
Ethylene glycol is poisonous. It does taste sweet and ultimately causes kidney failure.
Diethylene glycol is also poisonous. Polyethylene Glycol is not poisonous but it does do a great job of getting you ready for a colonoscopy. Propylene glycol is also safe as a food additive and also is called RV antifreeze.
