- NOTE: This project and these instructions have been written for someone who has experience making soap and knows the potential dangers due to working with sodium hydroxide. It will not outline all safety methods of working with dangerous chemicals, it is simply a soap recipe for advanced soapmakers.
- Put on your protective gear. This is very important since you will be working with an extremely caustic base that can and will burn you if you touch it. Noxious fumes are also released from the exothermic reaction that occurs when you mix the sodium hydroxide with water.
- Prepare the lye solution by weighing the water and lye in two separate containers. Pour the lye into the water, carefully mix in a well-ventilated area and set aside to cool while you prepare your oils.
- Measure the oils and butters in the funnel pitcher and melt in the microwave. Set aside.
- In separate plastic beakers measure out your fragrance oil and sodium lactate and set aside.
- When your lye water has cooled to 120° F or cooler add the sodium lactate and mix in.
- When both the lye mixture and the oils are approximately 100° F or below you can begin mixing. Pour the lye mixture into the oils.
- Stick blend until you reach a light trace. Add fragrance oil and blend in by hand or with a few short bursts with the stick blender.
- Pour the soap batter into each cavity of the mold and fill approximately ¾ full. Tap the mold on the counter to release any air bubbles.
- Add 2 tsp. of fig powder to the remaining soap batter and mix in. You want the soap in the mold to be thick enough that the remaining batter will not break through and you will have even layers. When the soap in the mold has reached this consistency, spoon the remaining batter into each cavity until filled to the top. Again, tap mold on counter to release any air bubbles.
- Allow to set at least 24 hours or longer until soap is firm enough to unmold. Remove soap from mold. If you have trouble unmolding you can place in the freezer for about 30 minutes.
- Let soap cure 4-6 weeks. Package and label accordingly.
