TKB Manchu Duck Concentrate
While it is non-toxic, the color is not cosmetic grade and so should not be used in personal care products.
Non bleeding and soap stable.
Manchu Duck is a sophisticated, muted blue green. Like the unique neck feathers of the manchu duck!
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.
