Yeah none of those luster dust formulations should qualify as "non-toxic" in my book.
Copper and lead salts are not only acutely and chronically toxic to humans, they can be disastrous to aquatic life if they get into water ways. Cu powder gets a solid GHS09: dead fish. Suprisingly does not get the the Health Hazard GHS8. PbS gets GHS7/8/9, right proper toxic.
Maybe they mean it's not acutely toxic? Usually either short or long term toxicity is more than sufficient to call something "toxic".
Yeah, I don't know. Maybe it's just a negligent error?
I'm not going to try eating some copper powder to find out, but I'd expect stomach acid to yield a substantial amount of highly soluble copper chloride. I guess I could try vomiting on some copper powder. But I won't.
