FWIW, much of this was recently discussed in this thread
> "...Hmmm...not sure if the petroleum in the jelly is good for the base..."
If by "petroleum", you are thinking of either gasoline or the raw stuff that comes out of oil wells, you don't have to worry. Neither is a component of "petroleum jelly". Rather, it contains a refined mixture of the medium-boiling waxy fraction of petroleum. For reference, this page
states that it is "mainly Mineral Oils, Paraffin Wax and Micro Crystalline Wax".This other page
states: "...You can make your own petroleum jelly (vaseline) from beeswax and mineral oil (liquid paraffin)..."
Because petroleum jelly is mostly a wax itself, while it might dissolve into and soften / liquify your base wax, it isn't going to do anything much more damaging than that. I have used it for a good while without trouble. The reasons I asked in that other thread about alternatives were: (a) Its messy and gets on everything; and, (b) its so soft that I would worry about it slowly creeping downhill because of the warm temps and long duration of summer storage.
