Brilliant blue fcf

Brilliant Blue FCF (CAS 3844-45-9), also known as FD&C Blue No. 1 and approved as E133, is a synthetic triarylmethane dye used to impart a bright, stable blue color across food, pharmaceutical, and cosmetic applications.

Its regulatory acceptance across major markets makes it a primary consideration for formulators requiring a blue colorant with broad approval status. In food and beverage manufacturing, it colors confectionery, beverages, and dairy products.

It is frequently used in processed foods where a vivid blue or blue-green shade is required. Pharmaceutical manufacturers use it to identify and differentiate oral dosage forms including tablets, capsules, and liquid preparations.

In personal care, it appears in rinse-off and leave-on products such as shampoos, bath gels, and topical creams where visual appeal drives consumer preference. It is also used in combination with yellow dyes to produce green shades.

This versatility expands its utility across multi-color formulation systems. The product is supplied as a water-soluble powder or granule, with granulated forms preferred where dust control is a handling priority.

Standard grades include FD&C for the US market, E133-compliant food grade, and cosmetic grade meeting relevant regional purity specifications. Pharmaceutical-grade material is available meeting USP and BP requirements.

These high-purity grades ensure suitability for use in regulated dosage forms. The material maintains excellent stability under various processing conditions, ensuring consistent color performance in the final product application.
