The propellants evaporate immediately at room temp, much less the oven........
I’ve used PAM ever since it first came out. I think it’s healthier to oil a pan with PAM rather than the old Crisco we used to use.
The questions that should be asked are:
-How much and what exactly is left behind?
-How toxic are they?
-Does the average consumer using the product get far more exposure to these chemicals than someone simply standing outside or drinking tap water?
