Re: TOTW & ethoxyquin
If you're not familiar with these, every chemical in the US (if it has any hazard) must have a MSDS (Material Safety Data Sheet). This is the one for Ethoxyquin. It does state that it becomes unstable in heat, but it also says that it gives off toxic fumes. I am NOT a chemist, so maybe someone else is more familiar with this than I am and can lend some insight.
