Indigo Powder. This natural indigo can be used for colouring Cold Process Soap and also M&P Soap, the end results do differ depending on the amount used and the coloured oils used in your soap. This is not a pigment or a synthetic colour but a totally natural indigo powder with no other additives.
For Cold Process Soap, the powder can be mixed with oils however we found better results when mixing with the lye water. Mixing into a paste before adding the rest of the water.
In Melt & Pour, mix a small amount with Rubbing alcohol and add to the soap.
We tested in Bath Bombs, however a lot of powder was required to get even the palest blue which looked more grey than blue.
