Slowly and carefully add the lye to the water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool to about 130° F.
Fully melt the annatto-infused coconut oil to 120-130 ° F. For this recipe, you need to soap on the warmer side to help prevent false trace. Read more about false trace here. Once the lye water and the oils have cooled to 120-130 ° F, add the lye water to the oils and stick blend until thin trace. Because this recipe is made from 100% hard oils, sodium lactate is not necessary for this recipe. The bars will be able to unmold within about 5-6 hours…maybe sooner!
Once you have a very light trace, add the essential oil blend and stick blend in.
Continue to stick blend the mixture until you have a light trace, and there are no oil streaks in the mixture. Alternate pulsing the stick blender and using it to stir the mixture throughout this step.
Pour the soap into each mold cavity until full. Tap the mold on the counter to help release air bubbles. Spritz the top with 99% isopropyl alcohol to help prevent soda ash.
Because this recipe requires a warmer temperature, this soap will have a tendency to gel. To help it go through a complete gel phase, and avoid a partial gel phase in the center, place the mold on a heating pad on medium heat. Gelling this recipe will also help the natural orange color become more intense. Create a “cardboard tent,” and cover with a blanket to fully insulate. After about 30 minutes, turn off the heating pad and allow to stay insulated for several hours. If you live in a warmer or cooler climate, the soap may need more or less time on the heating pad. Because this soap is made with only coconut oil, these bars can be removed from the mold very quickly! I would recommend giving them at least 6 hours to overnight to be on the safe side. Make sure you're wearing gloves, as the bars are still saponifying and the lye can irritate the skin. To remove, gently pull the sides of the mold away from the soap to break the airlock, and push the soap out from the bottom. Once removed, use the Soap Shaver to clean up the bars. Allow to cure for 4-6 weeks to create an even firmer, more long lasting bar of soap.
