Ready for part 3 of milk cold process soap? We are going to follow the same recipe and steps as the posts before, but we are going to use buttermilk instead.Again, here are the directions that we will follow in a step by step format.
1) Calculate the amount of lye and liquid needed for the oils you plan to use.2) Measure all of the oils and set aside to heat gently.
3) Measure the lye and set aside.
4) Measure HALF of the needed liquid as water and set aside. Measure HALF of the needed liquid as milk and set aside. Milk should be room temperature, not frozen or heated.5) Add ALL of the lye to the water. Stir well. No crystals should remain on the bottom of your mixing vessel. When the temperature of this lye solution is within 110° F to 130° F, (cooler in the summer and warmer in the winter, cooler for large batches and warmer for small batches), add it to the oil mixture. Blend with an immersion blender until you estimate you are halfway through the mixing process. This will happen with most oils in about 1 minute. The mixture should NOT be thick or viscous. The mixture should be very fluid, like water. 6) Now steadily pour the milk into the batch. Use the immersion blender to finish the blending so there is no chance of separation.
7) Add fragrance. Pour into prepared SHALLOW molds (1 inch deep or so). Milk soaps can get very hot and shallow molds help the excess heat dump into the air. This will prevent the milk sugars from interrupting the saponification reaction.This is called the Half and Half Method, because you use half water, half milk, and add the milk half way through the blending of the batch.
