  • Applications

    Basic Red 1:1 (CAS 12238-65-2) is a cationic dye used primarily as a colorant in a range of industrial applications: textile dyeing (notably on acrylic, nylon, and wool fibers), inks and coatings (printing inks, varnishes), and coloration of plastics/polymers; it is also employed for leather dyeing and may be evaluated for use in paper coloring as well as cosmetics/personal care formulations under local regulatory constraints.
