Description

Direct blue 218 is a glycol ether dye that is used in the textile industry and as a food coloring agent. It has been shown to cause nephrotoxicity and hepatotoxicity as well as cancer in rats. Direct blue 218 is absorbed by the target tissues, which include the ovary cells, liver cells, and kidney cells. This dye has been shown to inhibit catecholamine release from the adrenal gland in vitro assays and increase the number of mitotic figures in rat liver cells chronically exposed to this dye. Direct blue 218 also contains nitrogen atoms that can form a copper complex with an electron-donating group (e.g., hydroxyl groups). The copper complex increases its stability, leading to increased genotoxic effects.
