Would Ivory bar soap or some other natural hard soap (Grandma'a Lye Soap?)
work? Whereas the chained hydrocarbon barriers also provide lubrication,
they may be permeable to oxygen. Corrosion. Soap being a modified chained
hydrocarbon will give lubrication and the amphipathic charged end or
electronegative end may become hydrated and the combined electronegativity
provides a second barrier to Oxygen diffusion with a sort of negative Van
der Waals force. Then again, it might just freeze a second one solid. I'd
try hemp oil before anything else. It's good or best for almost every human
need, maybe its oil will show the same general property that all of its
other properties share, they're beneficial.
