Ponceau SX

Ponceau SX (CAS 4548-53-2), also known as FD&C Red 4 and E125, is a synthetic azo dye used to impart red coloration across food, textile, and industrial applications. Approved under distinct regulatory frameworks in different markets, it is sourced by formulators and procurement teams.

In food and beverage manufacturing, this colorant delivers a stable red hue in products such as maraschino cherries, fruit cocktails, and certain confectionery items where it remains permitted. Textile dyeing operations use it to color natural and synthetic fibers.

Consistent bath uptake makes it suitable for commercial-scale production runs. Leather finishing processes apply it to achieve uniform surface coloration in decorative and functional leather goods. Paper and packaging manufacturers incorporate it into colored paper stocks.

The dye is also utilized in specialty printing substrates requiring defined red tones. This versatile chemical is supplied as a fine red to dark red powder, ensuring ease of integration into various liquid and solid manufacturing processes across multiple sectors.

It is available in food-grade specifications aligned with FD&C and European regulatory standards, as well as technical grade for non-food industrial use. Bulk quantities are typically offered in fiber drums or multi-layer bags for large operations.

Smaller packaging is available for laboratory and formulation development purposes. Procurement teams can rely on this material for applications requiring high color stability and compliance with specific regional safety and quality guidelines for synthetic dyes.
