  • Applications

    Pigment Red 112 (CAS 6535-46-2) is an organic pigment widely used as a colorant in coatings and inks, delivering bright red hues with good color fastness; it is also incorporated into pigment concentrates for plastics to color polymeric materials, including polyolefins and other thermoplastics. In cosmetics and personal care, it may be used as a colorant in regulated formulations. In textiles, it can be employed in pigment-based coloration systems for fibers and fabrics under appropriate processing. Additionally, it is used in decorative ceramic glazes to impart red coloration, depending on glaze chemistry and firing conditions.
