Castor oil (from the drug store) is almost as good an EP lube as lanolin, and it is soluble in alcohol. It's also a lot easier to find than lanolin, and it's cheaper.
"IsoHeet" is a fuel line deicer that's 99% isopropyl alcohol and pretty easy to find.
I haven't tried mixing them yet to make a spray lube. I have used castor oil for sizing cases and it works great.
