  • Applications

    HC Yellow No. 15 (CAS 138377-66-9) is used primarily as a colorant in a range of industrial formulations; typical real-world applications include coloring inks (commercial and packaging inks), coatings and paints for industrial and consumer surfaces, colorants for plastics and polymer materials, textile dyeing and finishing, and, in regulated formulations, color additives for cosmetics/personal care; it can also serve as an intermediate or component in pigment synthesis and formulation blends.
