Activated Charcoal in Home Made Soap

Rectangular Black and Orange Swirls in Hand Made SoapAfter successfully producing a batch of home made soap using Carrot Oil  and Activated Charcoal for coloring the soap, I found that black soap doesn’t mean black bubbles and black skin.

On the contrary, the bubbles are white and the skin feels soft and cleansed after using soap colored with charcoal. So I now have green light to attempt a mostly black soap … and maybe to allow my creative juices to flow towards a seascape at night featuring a full moon.

And why not add some sea salt to make the soap as close to the whole sea concept as possible?

A few facts about activated charcoal: 

  •  Activated charcoal  chemically binds other substances to its surface and can absorb thousands of times its own weight.
  • A bit of charcoal can absorb so many toxins, atoms, and ions.
  • It can help reduce the instances of acne and other skin conditions caused by blocked pores, toxins, impurities. It also works wonders for completely removing makeup.
  • Some people sprinkle activated charcoal on their toothbrushes and brush their teeth with it. Result: brighter smiles.
  • Well, there’s a lot more to say about it, but the few facts above, convinced me to use the black powder in my soap making.

Activated Charcoal Moon Over the Sea Hand Crafted Natural Soap Recipe:

Note: (before attempting making soap at home for the fist time make sure you read all about the cold process soap making here and use a lye calculator)


  • Olive Oil 50.% (17.637 oz)  500  grams
  • Coconut Oil,  40 % (14.110 oz)  400.grams
  • Shea Butter 10.% (3.527 oz)  100.grams
  • Liquid:  (13.404oz)  380 grams (Aloe Vera Gel, Coconut Milk)
  • Lye – NaOH-  146 grams

I wanted to create something more than a few bars of soap so, this is my second attempt of creating a landscape soap. this time, I wanted the full moon over a moonlit, sea… , hills, not sure… I guess this bit can be left to anyone’s imagination.

In addition, I wanted this soap to be good for skin, gently exfoliating so I added dry ground aromatic leaves powders and freshly squeezed citrus peels.

Additions at trace: 

  • Sea Salt: 200 grams
  • previously made:  white Castile soap; carrot oil colored soap, pink mica powdered colored soap.
  •  Activated Charcoal (3 tbsp),
  • carrot oil for creating the swirls (1 tsp added to a cup of the soap mix at trace)
  • Scents: Essential oils: grapefruit,  peppermint,  cedar-wood, pine, clove
  • – the zest of 4 freshly grated limes
  • – 1tbsp of dry ground mint leaves
  • 1 tsp dry finely ground rosemary leaves
  • 1 tsp of dry finely ground sage leaves

  •  Hard bar of soap, a little grainy in places. s
  • The carrot oil soap swirls were supposed to look like moonlight reflections on the sea… oh well – must improve soap swirling techniques.
  • During the cure time outside in a well ventilated and shady place, it hardened further. On humid evenings, small drops of water appear on the surface of the soap. I guess that is the salt attracting water from the atmosphere…:(
  • After 3 weeks of curing, I wrapped the moon soaps in cling film – no more sweating and the soaps maintain their hardness. .


Moon soap Lather Test:

Three weeks into the curing time, it was time to test for soap bubbles :


  • disappointingly, the salt must have killed the lathering abilities of this soap. It takes a lot of rubbing to produce any soap suds on bare hands.

  • When the desired lather is finally achieved …. well it’s rather gray – that must be the activated charcoal leaking.

I will test again in a few weeks time and see if this color leak  issue improves.

  • On a plus side, my black soap cleans very well, the gray lather washes off with a simple rinse and all that’s left behind is a manly refreshing scent on hands and soft, refreshed, clean skin. Moreover, the activated charcoal is supposed to help draw toxins from skin, thus being useful in the treatment of acne and other skin conditions.


I test the soap weekly, and each time, the lather is whiter and richer. .  The dry plant used material (citrus peel and mint leaves) are visible, although not big enough to be scrubby. I’m starting to love this soap.
