I bring mascara, lip gloss, small cosmetics through in my purse, not in a ziploc bag, all the time. They never pay these things any attention. I always have room in my baggie and could put them in there if they caused a stink, but they never do.
I think they're all supposed to be in a baggie.. but those are the things I carry in my purse and maybe because they're small enough nobody cares. Someday somebody could hassle me but I fly a couple times a week and nobody has had a problem with my mascara or lipgloss. I'd play dumb, apologize, and and put them in my baggie if they did.
Note - I do have a baggie with all my other liquids that are larger in size and more 'liquidy'.. shampoo, conditioner, lotions, etc. That is still a rule. I don't want to mislead anybody!
