Direct Green 6（Cat No.:I026291）is a synthetic dye primarily used in the textile industry for coloring fabrics, particularly cellulose-based fibers like cotton. It belongs to the class of direct dyes, which can bond directly to fibers without the need for mordants or additional fixing agents. The dye is also used in other applications, including in the production of inks, paints, and cosmetics. However, concerns over the environmental impact of dye discharge and its potential toxicity have led to increasing regulation. Research into safer, more sustainable alternatives to Direct Green 6 continues in the industry.
