Failing finding the right stuff, try an simple experiment:
Get a bottle of the stuff (laxative aisle of your local drug store) and
pour it into a very clean jar and take a couple of long SS screws as
electrodes and see if you can measure any leakage resistance.
Maybe not a volt-nut approach, but workable but certainly good enough for
a 10 Ohm standard.
