Cover any exposed skin, wearing gloves, eye protection, and work in a well ventilated area.

Use a digital scale to measure out the water. Then, add it to the heat-resistant container.

Slowly add the lye to the water. Stir the lye into the water until dissolved. Note that the chemical reaction will cause it to heat up quickly. Set aside to cool to about 120-130°F

Melt the coconut and palm oil in a small saucepan on the stove over medium heat.

Once melted, set aside to cool slightly.

Add all the oils to a metal mixing bowl.

Pour the lye water in with the melted fat and oil a little at a time and mix with an immersion blender.

Continue adding the lye water and mixing between each round until the soap comes to trace.

To check the “trace,” hold the immersion blender over the bowl; if the soap drips and pools up on the top, it's come to the correct trace.

Whisk in activated charcoal

Pour the soap into the mold and let dry for 24 hours up to 3 days.

Cut the soap into bars, and space out on a drying rack for 5-6 weeks to fully cure.
