Nope, it's only 94-96% pure PG with 3% water and 1-3% inhibitor additives.
See the MSDS sheet here:

PG coolant is slicker than EG coolant. Don't get PG coolant on the floor. It takes a good long time to mop up.
There is also FDA food grade PG without the inhibitor corrosion protection. This is the pure PG formulation. PG is used in salad dressings, gummy bears, cough syrups, and the like as a food sweetner. It's also used with food grade equipment to lubricate mixing and spindle functions that touches food. It sure beats eating 10W-30.
