  • Applications

    Canthaxanthin (CAS 514-78-3) is a carotenoid pigment used primarily as a colorant in animal feeds and aquaculture to impart orange-red hues to egg yolks, poultry skin and meat, and to fish flesh. It may also be employed as a food colorant in processed foods where regulatory approvals allow. In cosmetics and personal care, canthaxanthin serves as a pigment for makeup and skincare products; in polymers and plastics, it can be added as a colorant for molded parts and packaging; in coatings and inks used in industrial manufacturing, it is utilized to enhance color richness and color stability of coatings and printed materials.
