TKB Turquoise Concentrate
It is among our "Jewel Collection" of colors and goes well with the other colors in that line.
Our color concentrates are water-soluble pigments or dyes suspended in vegetable glycerine.
1 fl.oz. should color about 20 pounds of soap to a medium shade.
While it is non-toxic, the color is not cosmetic grade and so should not be used in personal care products.
