Re: A report based on evidence instead of prejudice ?
While propylene glycol is considerably less dangerous than ethylene glycol, the MSDS lists skin, liver and kidney damage as possible effects from exposure and it has been forbidden to use in cat food due to it causing Heinz Body Anemia. Some individuals are apparently bothered by propylene glycol vapors as well.
So is it safe? Who knows. Wouldn't surprise me if the FDA does an about-face on this stuff in a few years, they spent over 5 decades telling us that chicken eggs would kill us only to finally realize they were shitheads.
