The stuff is basically propylene glycol. Its non toxic, used as a food additive. Problem with it is that its viscosity is much higher than conventional coolant & so there will be reduced flow especially through small spaces. Its heat transfer properties are not as good as conventional coolant / water blends. You would be a bit foolish to use the stuff undiluted in a cars cooling system that was designed for conventional coolant.
