Same with some granite countertop sealer I bought in a spray bottle. Had to dig online for a while before I could figure out what it's made of, which is almost pure PFAS. Crazy considering we prepare foods near it.
A bunch of the lubricants that are FDA approved for incidental food contact contain PTFE. It’s unclear how harmful the teeny tiny particles of PTFE are.
They bioaccumulate because the “forever” part means they don’t break down. The reason they’ve been banned in food wrappers is that they accumulate to levels that become toxic. We should avoid them every way we can.
you don't absorb quartz through your skin and is inert if it gets into your stomach. small particles won't hurt your guts and will get pooped out; ingesting dirt is something that is not uncommon with animals, including people.
