Does CAS 458-37-7 describe every commercial Curcumin powder?

No. CAS 458-37-7 identifies curcumin itself, while commercial turmeric-derived color products may contain a defined mixture of curcumin, demethoxycurcumin and bisdemethoxycurcumin. State whether the order requires isolated curcumin, total curcuminoids or a specific turmeric-derived product.

Is Curcumin the same as turmeric extract or turmeric oleoresin?

No. The materials can originate from turmeric but differ in composition, carrier, color strength and residual components. Identify the exact product type, curcuminoid or coloring-matter basis and botanical source where relevant.

What is Curcumin used for?

Curcumin is evaluated as a colorant, functional ingredient and chemical intermediate in food, cosmetic, dietary-supplement and research applications where the applicable grade is approved. The required purity, color value and regulatory status depend on the destination and use.

What are the key physical properties of Curcumin?

Curcumin is an orange-yellow crystalline powder with formula C21H20O6 and molecular weight about 368.38 g/mol. It has a typical melting point around 183 C, is practically insoluble in water, and is soluble in ethanol, DMSO, chloroform, acetone and acetic acid, with color that changes with pH.

Which batch data should be agreed for a Curcumin ingredient?

Confirm the assay basis, individual or total curcuminoid profile, color value if applicable, moisture, ash, residual solvents, specified metals and microbiological limits. Requirements vary by destination and use.
