C.I. Azul Direto 218

Descrição:

C.I. Azul Direto 218, com o número CAS 28407-37-6, é um corante sintético usado principalmente na indústria têxtil para tingir fibras de celulose, como algodão e rayon. Pertence à classe de corantes diretos, que podem ser aplicados diretamente em tecidos sem a necessidade de um mordente. Este corante é caracterizado por sua cor azul profunda e boa resistência à luz, tornando-o adequado para várias aplicações, incluindo papel e couro. Quimicamente, é um corante azoico, o que significa que contém um ou mais grupos azo (-N=N-) que contribuem para suas propriedades de cor. C.I. Azul Direto 218 é solúvel em água, permitindo fácil aplicação nos processos de tingimento. No entanto, como muitos corantes sintéticos, pode apresentar preocupações ambientais devido à sua potencial toxicidade e persistência no meio ambiente. As fichas de dados de segurança recomendam manuseá-lo com cuidado, pois pode causar irritação ao contato com a pele ou os olhos. No geral, C.I. Azul Direto 218 é valorizado por seu tom vibrante e versatilidade em aplicações de tingimento.

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.
