I would think it likely is the same. If named Vaseline, it would have to be the same.
Petroleum Jelly, ie: Vaseline, is a petroleum wax, not an oil or gelly still being a petroleum product that does not mix with BP fouling. That is why it works with BP.
Most petroleum products do not mix with BP fouling.
Vaseline does.
That is why Vas./BW makes a good BP lube. I have used in on REAL bullets in muzzleloading rifles to good effect as well as in a .50/90 Rolling Block and even with smokeless loads to 2,200fps in a .45 rifle with cast bullets.
Amazing stuff.
