Vegetable glycerin also works well for hydration in place of aloe, and has the advantage of not leaving residue on your hands. A bit harder to get your hands on, though.
It’s actually pretty easy to get, every pharmacy has it (extremely expensive), almost every ecig store that caters to DIY (expensive), and many stores for horse supplies (cheap). The quality (at least here in Germany) is exactly the same for all of them.
