C.I. Blu Diretto 218

Descrizione:

C.I. Blu Diretto 218, con il numero CAS 28407-37-6, è una tintura sintetica utilizzata principalmente nell'industria tessile per tingere fibre di cellulosa, come cotone e rayon. Appartiene alla classe dei coloranti diretti, che possono essere applicati direttamente ai tessuti senza la necessità di un mordente. Questa tintura è caratterizzata dal suo profondo colore blu e dalla buona resistenza alla luce, rendendola adatta a varie applicazioni, tra cui carta e pelle. Chimicamente, è una tintura azoica, il che significa che contiene uno o più gruppi azo (-N=N-) che contribuiscono alle sue proprietà di colore. C.I. Blu Diretto 218 è solubile in acqua, consentendo una facile applicazione nei processi di tintura. Tuttavia, come molti coloranti sintetici, può sollevare preoccupazioni ambientali a causa della sua potenziale tossicità e persistenza nell'ambiente. Le schede di sicurezza raccomandano di maneggiarlo con cura, poiché può causare irritazione al contatto con la pelle o gli occhi. In generale, C.I. Blu Diretto 218 è apprezzato per la sua tonalità vivace e versatilità nelle applicazioni di tintura.

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.
