Mehron clown paint for missions trip: will it melt in the plane?

im going on a missions trip to guatemala with brio magazine, and as a part of my costume(well be ministering through skits) i need to bring clown white face makeup. i bought the brand mehron(which is EXPENSIVE! dang clowns should be paid GOOD!) with 16oz of it. it needs to be in my checked luggage. will it melt, or ruin it in anyway by the heat of my suitcase on a plane?
