Seems like Peak 10X but made with PG vs. EG, like the old Sierra and Prestone Low-Tox coolants. I like the idea of a “safer” coolant, buses here are running glycerin-based coolant. Sierra and Low-Tox was pricey, and you can’t use a EG hydrometer to check freeze point.
New “safer” coolant at WM?

All coolants sold in the US since 2013 have been required to include a bitter-ing agent which makes them taste really bad so poisoning danger is greatly reduced. The lower boil over temps of PG is the main reason not to use it.
Absolutely!
I was changing out an oil pump in my mom’s 2008 Silverado 5.3 last summer and a drop got near the corner of my mouth. Bleah! That nasty taste didn’t go away for an hour.
Good to know
I've been running Prestone Low Tox in my Toyota for 10+ yrs. No complaints.

If you mean all brands of coolant, then yes.
Heard of a kid who got poisoned with coolant in their bottle. Animals also can’t taste Bitrex, which is used to embitter coolant. Cats, dogs and rodents especially not.
This is not quite accurate. Dogs and cats definitely are able to taste bitterness and they do find the taste of denatonium benzoate objectionable, though it is true that it does not have as strong a bitter taste to them as with humans.
We all know that they will eat disgusting things so denatonium benzoate is not a perfect deterrent, including for children, so you are absolutely correct that EG antifreeze is not "safe" to leave laying out, even with the bittering agent.
