In this soap making video, I show you how I color handmade soap blue 100% naturally.
Indigo powder is an ancient natural dye that can produce shades of blue ranging from light blue to dark blue, depending on how much you use.
Indigo is derived from the leaves of the indigofera tinctoria plant.
In cold process soap making, indigo can be used to color soap by making an oil infusion, or by adding the indigo powder to the lye solution.
Adding the powder to the lye solution is easier, faster and produces a more vivid shade of blue in the final soap. To avoid speckles, the powder has to be completely incorporated into the soap batter and blended well.
When using indigo to color handmade soap blue, it is important to use light colored oils in your recipe. Using lots of yellow colored oils or fats, like extra virgin olive oil or cocoa butter, can affect the final color. Forcing the soap to go through gel phase will make the color more deep & vibrant.
With indigo, a little goes a long way. If you use too much powder, it will bleed from the final soap, color the lather blue and possibly stain fabrics that come into contact with the soap.
