  • 6 Cavity Silicone Rectangle Mold
  • 0.7 oz. Castor Oil (5%)
  • 3.5 oz. Coconut Oil (25.4%)
  • 3.5 oz. Palm Oil (25.4%)
  • 5.6 oz. Olive Oil (40.6%)
  • 0.5 oz. Tamanu Oil (3.6%)
  • 2 oz. Sodium Hydroxide Lye
  • 4 oz. Distilled Water (15% water discount)
  • 0.6 oz. Tea Tree Essential Oil
  • 2 tsp. Activated Charcoal
  • 1 tsp. Sodium Lactate
SAFETY FIRST: Suit up for safe handling practices. That means goggles, gloves, and long sleeves. Make sure kids, pets, 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.
  1. Slowly and carefully add 2 oz. of lye to 4 oz. of water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool to about 120-130 degrees F. 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, add 1 teaspoon sodium lactate.
  2. Completely melt the bags of coconut oil and palm oil in the microwave with the caps on. Weigh 3.5 oz. of coconut oil, 3.5 oz. of palm oil, 0.7 oz. of castor oil, 0.5 oz. of tamanu oil, and 5.6 oz. of olive oil into a medium glass container. Set aside until it reaches 120-130 degrees F.
  3. With gloves and goggles on, add the lye water to the oils. Pulse the blender on and off to mix. Continue to pulse and stir for about 1-2 minutes.
  4. Once the soap is a pudding-like texture and the oils are fully mixed, add 0.6 oz. of essential oil and 2 tsp. of charcoal. Whisk until combined.
  5. Pour the soap into each cavity of the mold. Tap the mold on the counter to get rid of bubbles. Place the mold onto a heating pad set to medium for 2-3 hours. Turn the heating pad off and allow the soap to harden for 2-4 days.
  6. Pull two sides of the cavity away from the bars of soap. If the cavity releases easily, pull the other two sides away and gently press the soap out from the bottom. If the soap sticks to the mold, let it harden for another day and try again.
  7. Allow the soap to cure on a well-ventilated shelf for 4-6 weeks to create firm, long-lasting bars. Enjoy.
