So... this MSDS of Evans Waterless Coolant says it's ethylene glycol, propylene glycol and "corrosion inhibitors". According to various internet anecdotes, it's around 69% ethylene glycol, 29% propylene glycol, 2% whatever additives.
This MSDS of Castrol ethylene glycol (a conventional coolant/antifreeze) says it's .. ethylene glycol

This MSDS of Amsoil propylene glycol (a conventional coolant/antifreeze) says it's propylene glycol
http://www.amsoil.com/msds/ant.pdf
This page on Evans' website says it's a "patented non-toxic liquid" and then goes on to say at the bottom that traditional coolant/antifreeze is toxic, even though Evans is made of both of the most common traditional coolants mixed together...
Evans Waterless Engine Coolants - FAQs - frequently asked questions
It should be noted that ethylene glycol is in fact quite toxic when ingested, and while e-cigs and many food items (creamy salad dressings, for example) contain propylene glycol I wouldn't exactly recommend taking a swig of it straight.
So I'm curious; why do they declare Evans "non-toxic" when it's mostly ethylene glycol (that IS quite toxic) -
and, why do they make such a big deal about not contaminating it with water when you totally contaminate the same ingredients with water all the time in normal coolant systems. Is it because it's mixed propylene/ethylene, where they play nice together as long as there's no water but then they start having a problem?
