It is slightly bluish soy sauce-based color materials (color Lunt pigment).
Please use him as powder cosmetics such as coloring or the eye shadow of the soap.
As a color is dark and is hard to just use it when I use you as cosmetics, it becomes hard to fail when I weaken it and use it for 5 times (40 g including iron oxide 10 g titanium) with titanium dioxide, white kaolin.
[please confirm it before the purchase] As you produce hydrogen sulfide when you combine it with acid, please do not mix it. As I cannot mix it with citric acid, it is not usable for the coloring of the bus bomb.
