¡Look at (and READ) the pink stuff jug!
On the advice of a friend that used to be a product engineer for a major OE chemical supplier, I have started reading the jugs of RV anti-freeze that I have.
The old ones were straight Propylene Glycol (safe to drink).
The newer ones have giant lettering that say SAFE, but do not say what they are safe for....
They are denatured alcohol, gycol (unspecified) color, water and something I don't remember. If I had this in my potable system, I would be very careful to flush the system very well in the spring.
You can probably still find PG based anti-freeze, but it won't be cheap.
