Doesn't it say what the ingredients are somewhere in the bottle (perhaps in some fine print, or in an ingredient list)? Also, if this were EG it would give dire and drastic warnings that this is a poison. Only PG can be labelled as "non-toxic antifreeze". I don't know an easy way to tell the difference.

And it is true that the amount you added was so small that it should not be a problem. First of all, you aren't drinking your pool water and secondly, even if your kids swallowed some pool water it would be extraordinarily diluted. So yes, you are probably safe.
