  • Applications

    Chlorophyll (CAS 1406-65-1) is a natural green pigment primarily used in foods and beverages where permitted, as a colorant in cosmetics and personal care products, and as a pigment in inks, coatings, and plastics to impart green hues across applications. In addition, chlorophyll can serve as a natural color source for decorative formulations and packaging materials, and may be considered for other industrial coloring applications where allowed by local regulations. Use is subject to local regulations and formulation limits.
