Activated Charcoal Cold Process Soap Loaf for Beginners Recipe
Author: Wholesale Supplies Plus
Thursday, February 16, 2017

This recipe contains activated charcoal, which is thought to detoxify the body. We also added Icelandic Seamoss Natural Fragrance Oil for a cool, detoxifying scent. We think this soap makes a great facial bar, and the recipe is simple enough even for beginners!

Recipe Directions

  1. 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.
  2. 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.
  3. 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.
  4. Measure the oils and butters in the glass bowl and melt in the microwave. Set aside.
  5. In plastic beaker measure out fragrance oil and add activated charcoal. Mix together and set aside. 
  6. When both the lye mixture and the oils are 120°F or below, carefully pour the lye mixture into the oils. 
  7. Stick blend until you reach a light trace. Add the fragrance/charcoal mixture and mix with spatula by hand or with a few short bursts of the stick blender. 
  8. Pour the soap batter into the mold and tap the mold on the counter to release any air bubbles. Using a spoon or spatula, texture top as desired. 
  9. Allow to set at least 24 hours or longer until soap is firm enough to unmold. Remove soap from mold and slice into bars.
  10. Let soap cure 4-6 weeks. Package and label accordingly.
