Brilliant blue FCF

Brilliant Blue FCF (CAS 3844-45-9) is a synthetic triarylmethane dye registered under CI 42090 and commonly referenced as Blue 1 or FD&C Blue No. 1. It carries no EU E-code for food use but is approved in multiple jurisdictions under various regulatory frameworks. It is commercially identified by codes including blue1206 and 1206blue.

In food and beverage formulation, Brilliant Blue FCF functions as a water-soluble colorant that produces stable blue to green hues across a broad pH range, making it suitable for confectionery, beverages, and dairy applications. In pharmaceutical and personal care manufacturing, it serves as a colorant for oral dosage forms and rinse-off cosmetics. It also demonstrates catalytic activity in select oxidation and photocatalytic reaction systems.

Brilliant Blue FCF is available as a fine crystalline powder in food-grade and cosmetic-grade specifications aligned with FCC and relevant REACH registration requirements. Standard packaging formats include fiber drums and multi-layer bags. Suppliers should confirm grade-specific certificates of analysis prior to procurement.
