I tried it. It was a mess.
Hi there. I'm new to this forum but was doing a search for Whiskey soap and found this thread so thought I'd share my experience.
DON'T DO IT.
Or, rather, do it, but expect to lose a lot of perfectly good whiskey. Also, you'll make a toxic mess:

The lye doesn't really dissolve all that well, but that's just the beginning. It got VERY hot very fast and I threw it in an ice bath pretty immediately. It was very unstable.
By the time it cooled down to 120 and I got the oil up to 120, the thing was steaming some awful toxic stuff. I'm very glad I have a huge industrial fan over my workshop.
As I poured the lye/whiskey mix in, there was some strange chemical reaction that caused the whole thing to seize in a mushroom cloud up the center of my blender. It was VERY exciting. It looked like the whole thing might just erupt, but it didn't. It just turned into a solid bucket of soap.
I tried to scoop it into molds, but it was absolutely the most disgusting toxic mess I've ever seen. Even worse than the non-stick coated pan. And even worse than the frothing glitter issue.
So, in other words, "don't try this at home." (Unless you want to... because it was pretty cool.)
We've been experimenting with Whiskey fragrance oils instead and have been having very good success:

I've heard of a lot of people having great luck with beer. The Soap Queen had a nice video about Kahlua. I think the water content of both make those a little different story than the whiskey.
