Nero Diretto 22

Descrizione:

Nero Diretto 22, con il numero CAS 6473-13-8, è un colorante azoico sintetico utilizzato principalmente nell'industria tessile per tingere cotone e altre fibre di cellulosa. Questo colorante è caratterizzato dal suo profondo colore nero e dalla sua eccellente resistenza alla luce, rendendolo adatto per applicazioni che richiedono durabilità. È solubile in acqua, consentendo una facile applicazione nei processi di tintura. Tuttavia, come molti coloranti azoici, Nero Diretto 22 può sollevare preoccupazioni ambientali e per la salute a causa della potenziale liberazione di ammine aromatiche durante la degradazione. La sua struttura chimica include tipicamente più anelli aromatici e gruppi funzionali che contribuiscono alle sue proprietà di colore. Le schede di sicurezza indicano che deve essere maneggiato con cura, poiché può causare irritazione della pelle o reazioni allergiche in alcune persone. I quadri normativi in diverse regioni possono imporre restrizioni sul suo uso a causa di considerazioni ambientali, sottolineando l'importanza di pratiche responsabili di gestione e smaltimento nelle applicazioni industriali.
