It's a glycol, but not Ethylene glycol. I've found references claiming
it's Propylene glycol (which I doubt), Polyalkylene Glycol Ether, and
Hexylene Glycol aka 2-methyl-2,4-pentanediol .
All of the glycols are normally produced from crude petroleum, and so
qualify as 'petroleum products', but most of them aren't very toxic. They
also bio-degrade fairly easily. Propylene glycol is actually used in many
hand lotions, etc. and in anti-freeze for drinking water systems (like my
motor home).
