SAFETY FIRST: Suit up for safe handling practices! That means goggles, gloves and long sleeves. Make sure kids, pets, and other distractions and tripping hazards are out of the house or don’t have access to your soaping space. Always soap in a well-ventilated area.
FRAGRANCE PREP: Measure 1.7 ounces of Tea Tree Essential Oil into a glass, essential oil safe container. Set aside.
  1. 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.
  2. Fully melt the castor oil, coconut oil, olive oil, palm oil and tamanu oil (remember to fully melt then mix your entire container of palm oil before portioning).Once the lye water and the oils have cooled to 130 degrees or below (and are ideally within 10 degrees of each other), add the lye water to the oils and stick blend until thin trace. If you’d like a harder bar of soap that releases faster from the mold, you can add sodium lactate to the cooled lye water. Use 1 teaspoon of sodium lactate per pound of oils in the recipe. For this recipe, you’d add 2 teaspoons sodium lactate. Stick blend the soap until it’s at a thin trace.
  3. Add 2 Tbsp. activated charcoal to the soap. Use your stick blender to "tap down" the charcoal to start to mix it into the batter. If you turn on the stick blender immediately, the charcoal may "poof" into the air. Slowly pulse the stick blender to incorporate the charcoal.
  4. Add the tea tree essential oil to the soap, and use the stick blender to blend and stir the essential oil until completely mixed in.
  5. Continue to stick blend for just a few seconds, to make sure the ingredients are completely combined. When the soap is a medium trace and is still pourable, pour the batter into the individual cavities of the 12 Bar Rectangle Mold. Tap the mold on the counter to even the soap and get rid of bubbles.
  6. Spritz the top of the soap with 99% isopropyl alcohol to prevent soda ash. Place on a heating pad set to medium heat, and insulate the soap for about 30 minutes. Turn off the heating pad, and leave the soap insulated for 24 hours.
  7. Allow the soap to stay in the mold for at least 3-4 days. Because this soap has plenty of soft oils, it may need up to a week in the mold. Don't rush it! Once the soap is firm enough, unmold and allow them to cure for 4-6 weeks. Enjoy!
