  • Applications

    Light green SF yellowish (CAS 5141-20-8) is a soluble dye/colorant that can also serve as an intermediate in colorant synthesis. In practice, it is used for textile dyeing to yield light-green-yellow shades; as a colorant in printing inks and coatings for plastics and paper substrates; as a colorant in cosmetics and personal care formulations under regulatory controls; as a colorant for paper and packaging applications; and it may function as an additive colorant in adhesives where identification or coloration is desired. Use is subject to local regulations and formulation limits.
