Carmoisine Granular

Deliver consistent and vibrant red coloration in industrial formulations with Carmoisine Granular (CI 14720, E-122) — a synthetic monoazo dye engineered for reliable aqueous solubility and stable performance.

Unlike fine powder, the granular form offers improved handling characteristics, reduced dust formation, and better flowability during industrial batching processes. This makes it especially suitable for large-scale detergent and technical fluid manufacturing.

Carmoisine produces a bright red to crimson shade depending on dosage and formulation environment. With a molecular formula of C20H12N2Na2O7S2, it dissolves rapidly in water, ensuring uniform color distribution.

Regulatory Position – NON-FDA Grade

Although Carmoisine (E-122) is permitted under European regulations, it is:

• NOT approved by the U.S. FDA
• NOT listed under 21 CFR color additive regulations
• NOT permitted for food, pharmaceutical, or cosmetic use in the United States

This product is therefore classified strictly as Industrial / Technical Grade (Non-FDA).

Advantages of Granular Form

✔ Reduced airborne dust during handling
✔ Easier bulk measurement
✔ Improved material flow
✔ Lower clumping risk in humid environments
✔ Ideal for automated dosing systems

For manufacturers of detergents or cleaning solutions where production efficiency matters, granular dye simplifies operations while maintaining color strength.

Typical Non-Regulated Applications

• Liquid and powder detergents
• Industrial surface cleaners
• Technical soap formulations
• Laboratory tracer solutions
• Textile research
• Paper and pulp processing trials
• Industrial fluid identification

Imagine producing a visually distinctive red cleaning solution where consistency is essential — Carmoisine Granular dissolves quickly without altering viscosity or chemical performance.

Technical Performance Characteristics

• Highly soluble in water
• Strong tinting strength
• Stable under neutral to mildly acidic conditions
• Moderate heat stability
• Avoid prolonged exposure to strong alkaline environments
