C.I. Azul Directo 218

Descripción:

C.I. Azul Directo 218, con el número CAS 28407-37-6, es un colorante sintético utilizado principalmente en la industria textil para teñir fibras de celulosa, como el algodón y el rayón. Pertenece a la clase de colorantes directos, que se pueden aplicar directamente a las telas sin necesidad de un mordiente. Este colorante se caracteriza por su color azul profundo y buena resistencia a la luz, lo que lo hace adecuado para diversas aplicaciones, incluyendo papel y cuero. Químicamente, es un colorante azoico, lo que significa que contiene uno o más grupos azo (-N=N-) que contribuyen a sus propiedades de color. C.I. Azul Directo 218 es soluble en agua, lo que permite una fácil aplicación en los procesos de teñido. Sin embargo, al igual que muchos colorantes sintéticos, puede plantear preocupaciones ambientales debido a su potencial toxicidad y persistencia en el medio ambiente. Las hojas de datos de seguridad recomiendan manejarlo con cuidado, ya que puede causar irritación al contacto con la piel o los ojos. En general, C.I. Azul Directo 218 es valorado por su tono vibrante y versatilidad en aplicaciones de teñido.

Direct blue 218

CAS: 28407-37-6

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.
