Today I eventually conquered my procrastination after my treatment. I had a batch of melt and pour soap base. I melted and added a half teaspoon of Spirulina powder. The powder provides an amazing light green colour that no other colourants can provide. However, I would advise using the powder with caution as too much can give your soap a bad smell. I added French green clay and Peppermint fragrance. It has a great lather and the colour and smell is wonderful. My neighbours are very happy with it.
