I don’t see goats milk in the oil list. How can I add it to a recipe?
Whole goats milk contains only about 4% fat, so even if you replace all the water in a recipe with goats milk, it will have a very small effect on the amount of lye.
For this reason, we did not include goats milk in SoapMaker’s list of base oils. For example, if you made a tallow recipe and replaced all the water with goats milk, it would require only 1.6% more lye.
You can include goats milk as an additive, and reduce the water amount accordingly. The goats milk can be used to super-fat, or you can reduce the lye discount by one or two percent if you prefer.
