Thanks! In this case the material affected is (at least I believe it is) aluminum.

Take for example a nail polish OPI released a while back called “When Monkeys Fly!” that had issues with “Taco” glitter. I think they even pulled this off the shelves after people didn’t buy their excuse that this was by design.

Here’s a pic from a Google image search (on the left).

I was all over Google. I also checked out ULProspector and even Alibaba (though i’d rather not import if possible), 

Are there any other good chem/material search engines I should be looking at? I finally found a supplier this morning (Dorsett and Jackson) that looks like they can take care of the first one.

The second one I can’t seem to locate anywhere. It’s in a bunch of nail polishes from various brands too… might need an alternative for this one.
