You are correct.  Proplyene glycol is actually used as a food additive.
The most well-known brand I've heard of is called Sierra.

Read about it though, seems like it's really not the best choice.  Heat
can break down forming acids which corrode your cooling system, it can
also support bacteria growth causing slime and corrosion (though I'd
guess in an engine the heat would tend to kill off any bacteria).
