    Curcumin CAS 458-37-7

    Curcumin, chemically identified as Diferuloylmethane, is a hydrophobic polyphenol pigment utilized as a versatile industrial ingredient. It functions as a natural colorant and antioxidant stabilizer in functional food formulation, providing a distinct yellow hue and stability to lipid-based matrices. This bulk material, also technically referenced as Natural Yellow 3 or C.I. 75300, is processed to strictly control heavy metal content and solvent residues for regulatory compliance in nutraceutical and cosmetic manufacturing. We provide competitive factory pricing and ensure customized specifications regarding particle size and purity. Each batch is supported by full documentation including MSDS, TDS, COA, and is available for bulk supply to global industrial partners.

    FAQ - Technical & Supply Chain

    • Q:

      Does Diferuloylmethane refer to the same chemical substance as Curcumin?

      A: Yes. Diferuloylmethane is the systematic chemical name for Curcumin. Both terms designate the specific compound registered under CAS 458-37-7, distinct from the broader category of turmeric oleoresins.
    • Q:

      Is this grade of Curcumin water-soluble for direct aqueous formulation?

      A: No, Curcumin is naturally lipophilic and practically insoluble in water. For functional food formulation involving aqueous systems, it typically requires dispersion agents, emulsification, or encapsulation technologies to ensure uniform integration.
