Erythrosine

Erythrosine (CAS 16423-68-0 ), also known as E127 and erythrosine sodium anhydrous, is a synthetic red dye derived from fluorone. It delivers a bright cherry-pink to red coloration across food, pharmaceutical, and industrial applications.

It is one of the few certified red colorants approved for specific food uses in multiple regulatory markets. This makes it a reliable option for formulators working within defined compliance frameworks and strict safety guidelines.

In food manufacturing, it is used to color maraschino cherries, candied fruits, and certain confectionery products where a vivid red shade is required. Pharmaceutical tablet coatings and oral dosage forms use it for product identification.

In printing inks and packaging, it contributes to red and pink tones in water-based ink formulations. The textile and paper industries apply it as a dye for specialty coloring processes where its fluorescent properties support visual effects.

The product is supplied as a fine red powder or water-soluble granules. It is available in food-grade specifications certified to FCC and E127 standards, ensuring high purity for human consumption and safety.

Pharmaceutical-grade material is also available meeting USP and BP requirements. Technical-grade material is offered for industrial dyeing and printing applications where specific regulatory certifications are not required.
