How to make purifying soap

Before you begin

As activated charcoal is a very light, fine powder, it must be handled with caution and care. 

Ingredientshomemade soap

Sodium hydroxide solution

Oil and butter mixture

Superfatting oil



Essential oils


Good to know!

  • This soap recipe uses activated charcoal for its adsorbent and detoxifying properties; charcoal helps draw out and remove impurities. We decided to combine this ingredient with willow bark extract, which is rich in salicylic acid and will help purify and smooth your skin.
  • Our mixture of essential oils is perfect for caring for oily skin.
  • We chose to use hazelnut oil as our superfatting oil to benefit from its wonderful properties. Hazelnut oil has a non-greasy feel, is quickly absorbed by your skin, and has balancing properties.
  • For our soap, we chose to use two different types of mica because that was the effect we liked best. You can, however, replace them with the mica of your choosing.

Steps to follow

  1. Prepare and disinfect your equipment and workspace.
  2. Take the necessary precautions for handling sodium hydroxide safely.
  3. Prepare the sodium hydroxide solution: weigh the water in a Pyrex measuring cup or HDPE pot, weigh the sodium hydroxide, pour the sodium hydroxide into the water, mix well, and set aside to cool. 
  4. Weigh the coconut oil and shea butter in the large bowl. Melt on the double boiler.
  5. Weigh the olive oil in the first small bowl.
  6. When the coconut oil and shea butter have melted, remove them from the heat and add the olive oil. Mix the oils and butter together with the spatula.
  7. Weigh the hazelnut oil (the superfatting oil) in the second small bowl and set aside. 
  8. Weigh the activated charcoal in the first ramekin, then add it to the melted oil and butter mixture. Use the spatula to disperse the charcoal thoroughly. diy charcoal soap
  9. Weigh the essential oils in the second ramekin and set aside.
  10. Weigh the willow bark extract in the third ramekin and set aside.
  11. When the oil and butter mixture and the sodium hydroxide solution have both cooled to 35–40°C, pour the sodium hydroxide solution into the oil and butter mixture. Mix with the immersion blender and the spatula until the mixture is homogeneous. If either mixture is still too hot, you can place it in a cold water bath to bring down the temperature more quickly. how to make a purifying soap
  12. When the batter reaches trace, add the superfatting oil, willow bark extract, and essential oils to the soap batter and continue to mix with the immersion blender and spatula. 
  13. Don’t wait for the soap batter to reach trace again. As soon as the batter is homogeneous, pour half the batter into the measuring funnel pitcher, then continue to mix the batter remaining in the bowl. When it reaches thick trace, pour the batter from the bowl into the soap mold. Create effects on the surface of the soap with a spatula or a spoon. 
  14. Using a mesh strainer, dust some gold leaf mica over the top of the soap. Don’t add too much or the two halves of the soap may separate.
  15. Mix the second half of the soap batter using the immersion blender and spatula. When the batter reaches medium trace, pour it into the mold by pouring the soap batter on the spatula to soften the fall of the batter onto the mica. If the batter hits the mica with too much force, the mica will mix with the batter and you’ll lose the pretty, glittering line. Create effects on the surface of the soap using a spatula or spoon.
  16. Using a mesh strainer, dust some brushed copper mica over the top of the soap.
  17. Cover the soap for 24–48 hours. 
  18. Wear gloves to unmold the soap. Cut the soap and leave it in a cool, dry place to cure for four to six weeks.
