  • Applications

    Carthamin (CAS 36338-96-2) is a natural red pigment derived from safflower (Carthamus tinctorius). In practice, it is used as a colorant in cosmetics and personal care products; as a pigment for coatings, paints, and printing inks; considered as a natural food colorant in select markets; and used as a colorant in plastics and rubber formulations to impart red hues. Its use is subject to local regulations and formulation limits.
