Special Ingredients

1 ½ tablespoons hardwood activated charcoal powder and .5 oz. grapefruit essential oil (Crafty Bubbles brand).


Combine oils, saving about an ounce of olive oil to mix with the essential oil. At a light trace add the charcoal powder. Right before pouring the soap into the mold add the essential oil mixed in with the ounce of olive oil and hand stir.

Batch Notes

Somehow I totally messed up the percentages of each oil addition when I printed the recipe and didn’t notice until it was too late. I actually meant to use 50% olive oil, 30% coconut oil, 15% Shea butter, and 5% castor oil. It looks like the recipe will still turn out alright, even though its not what I originally intended. The only problem is the resulting recipe is pretty low on the recommended range for cleansing that means we should get a very mild soap with a recipe formulation more similar to African Black soap, which might not be such a bad thing. One other thing to note is the grapefruit essential oil played really nice with cold process soap making and smelled awesome. In the future I’d probably double (or even triple) the grapefruit essential oil, after the soap set the citrus smell had faded quite a bit.
