Ok, heres the deal. I want to invent a water-soluble round ball patch lube for muzzle loaders. It needs to be not messy (not a grease), and needs to actually lubricate the bore a little (like thin oil), not make tar in the bore, and be something that can be used to pre-treat pre-cut patches or strips of patch cloth and not evaporate. Water or spit can be added if necessary or to a patch clean the barrel as needed when shooting.
I don't want water-soluble cutting oils because there's a better option: GLYCOLS.
Question is which glycols. Aqua based cutting fluids are sometimes made from propylene glycol base, alcohol, anti rust, and anti-oxidant additives and pH modifiers.
I want something better, like WATER SOLUBLE PAG OIL.
PAGs don't burn, don't sludge, they lubricate well, have incredibly high viscosity indexes, tend to act like solvents, mix with water, don't smoke when hot and a bunch of other good stuff.
But to prevent evaporation loss of the oil itself, anti-oxidants need to be added. Anti rust additives would be nice, and maybe some detergents and dispersants...maybe. Problem is knowing what stuff to put in the water-soluble PAG base and how much to round it out as a patch lube, and can we focus on keeping toxicity down?
What would be great is a brand and product name of a PAG cutting/tapping fluid intended to be used straight or diluted no more than say 100% with water. Such a product would already have the additives needed and could be used as-is if it only existed. Does it exist?
I'm going to dive into my fancy oil stash and run a couple of different straight PAGs this weekend to prove the concept and if it works like I think it will I'm gonna be on the warpath again to develop a finished formula.
