Are any natural waxes PH neutral?

I'm a collector of historical artifacts, and one of the most common methods to preserve them is waxing. And one of the best options out there is Renaissance Wax, a microcrystalline wax. The reason it is considered superior to natural options like beeswax is that it is PH neutral, meaning it will not corrode the artifact over time with its acid content.


My only hesitancy to continue using it would be that it is petroleum based. I'm curious if any natural waxes offer the PH neutrality that RW does, as well as being just as long lasting for protecting items from moisture.
