  • Applications

    Pigment brown 1 (CAS 6410-40-8) is a colorant used in several industrial sectors. It is commonly employed as a pigment in coatings and paints, printing inks, and plastics/polymers to impart brown shades. It may also be used in adhesives and laminates where durable color is required, and, depending on regulatory acceptance, may be evaluated for cosmetic/personal care color formulations.
