I am based in the US. I am preparing to move out, and am thinking of giving some nail polish and polish remover to some people who will be visiting me before my move, since they will have more use for it. I believe that they are flying to Hong Kong afterwards.
Nail polish remover contains acetone, which clearly is inflammable, and I've heard that "paints" are also often prohibited (e.g. here).
Is it safe to assume that nail polish remover is prohibited?
More importantly, does the same hold for nail polish? Or does this depend on the airline? (For instance, this website seems to suggest that the TSA is fine with such items provided that they are checked in.)
The thing is, if it's outright banned, I can probably just donate my materials to my neighbours, but if not, I'd like to give them to people I know better (who, in this case, happen to be travelling by air).
