C.I. Solvent Black 27
C.I. Solvent Black 27 is a colorant, or dye. We add dyes to products for a variety of reasons including helping you see where you applied the product, when a product is used up, or for aesthetic reasons. In Shoe Care products, dyes or pigments also help to restore color or scuff cover. The colorant is available from multiple suppliers, which are responsible for its contents.
