You can use goat milk instead of water (but keep it cooler, maybe even freeze the goat milk before adding lye to it), you can add bentonite clay to any recipe, and castor oil is great at 5% of the oils.
When you build the recipe, just use goat milk instead of water in the liquids section, and add your oils to the recipe as usual, but add 5% castor oil and subtract some of the other oils to make up the difference. Clay is added in the ‘additives’ area, and a good amount to add is about 1 teaspoon per pound of oils in your recipe. The calculator will do that for you in the software program.
