Might as well, just to be on the safe side.. but your right to be smart man. I agree, if they are in your toiletry bag & if your checking the stuff.. I wouldn't worry what so ever.
like i said... i just traveled with over 10 bottles in my checked bags WITH the labels on them and the TSA did search my bag and they did not take them...
check them in but you better make sure you put them in a bag in case they leak being thrown around .. those guys just throw bags around cause they are rushing to load and unload.
if you carry on they could take them away if its a liquid.. they took my water last time i went.. they don't want liquids on carry on's! not even toothpaste !!
They will take it for sure if you try to carry on. They don't allow liquids at all outside of milk in a baby bottle... and they even take that to set inside some sort of testing device to make sure its really milk and not something else. They don't fuck around when it comes to carry-ons. I wouldn't be afraid to check it though with my other toiletries
