Natural colorants can be marvelous in soap!
For a subtle, light green-beige color in your soap, you can use cucumber - skin, flesh, seeds and all. You can use this recipe with any soap recipe - or create your own soap recipe. Just substitute well-pureed cucumber (get out that old blender!) for the water in your recipe. The cucumbers have so much water in them as it is, you can use up to 100% cucumber in exchange for the water. The skin is what gives the soap its color, so if you want more color to the soap, add in a higher ratio of skin to the liquid. (i.e. two or three cucumbers worth of skin, but just one cucumber worth of insides.)
Here's the recipe I used for this batch. (Be sure to run your recipe through a lye calculator if you change the size or oils!)
Makes two pounds of soap
- 7.5 oz. olive oil
- 7.5 oz. coconut oil
- 7 oz. palm oil
- 1.5 oz. castor oil
- 1.5 oz. cocoa butter
- 7.5 oz. total liquid (one large cucumber, and the skin off of a second)
- 3.6 oz. lye
- optional 2-3 tbs finely ground cucumber skin - patted very dry with a paper towel after grating - gives little green specks to the soap.
Natural colorants like spirulina or even green oxide can give a darker green swirl in the light green soap.
