I made a soap with goat milk in place of water. (It was actually gm powder if that makes any difference to you. I used some of the lye water to mix it in and added it to the oils when it was fully dissolved.) I used four butters and babassu in the soap. I've tried out some slivers. Oh my gosh! Love it. It is a creamy decadent bar that I am saving for the winter when my skin gets dry and painful. The downside is it is pretty soft. I just pulled a sliver out to test it again to refresh my memory. The sliver is bendable. The bar feels fairly hard, I can't bend it or dent it with my finger. But I'm thinking this will not last long at all. For what it is worth, I made a 500 g test batch 45% lard, 5% castor oil, and 10% each of cocoa, kokum, mango, shea and babassu. My regular soap treated my skin well last winter; I'm hoping this GM+Butter soap will be even better on my skin. If it is, I may make it again using less lard and more babassu. Now that I've got tallow in the garage, I might put some of that in there and compare the two.
