I started with the Beginner’s Cold Process Soap Kit from Brambleberry with a simple recipe of Olive Oil, Palm Oil, Coconut Oil and Castor Oil (kit comes with lye, fragrance oil and 2lb mold).
After some experimentation with different oils and butter, I use the above ingredients along with Shea and Cocoa Butter. I also invested in a couple of 1lb molds to test new scents and colors.
With regards to making Goat Milk Soap, I use equal parts frozen Evaporated Goats Milk and frozen Distilled Water mixed with my lye in an ice bath (ice, water & salt). I mix in the lye slowly to maintain the creamy color of the milk. I soap GMS around 70-75F and then refrigerate it. I then bring it to room temperature to mold and then wait another day to cut.
The above is the result of my first 2lb batch of GMS which was a failure. I froze the Goat Milk, but not the water and no ice bath. I then put it in the garage...in July...and covered it with towels. It overheated...badly. It was a medium brown, the top was rough and there was oil floating on top. Letting it sit (as was recommended) for a few days did see most of the oil reabsorb, but then I cut it and it sweated oil.
