Carmoisine

Achieve consistent, vibrant red coloration in industrial and technical formulations with Carmoisine Powder (CI 14720, E-122) — a synthetic monoazo dye known for its strong tinting strength and reliable solubility in aqueous systems.

Carmoisine produces a bright red to crimson shade depending on concentration and formulation conditions. Its molecular structure (C20H12N2Na2O7S2) allows rapid dissolution in water, making it suitable for non-regulated applications where stable red coloration is required.

Regulatory Status – Important U.S. Compliance Notice

Carmoisine (E-122) is authorized for use in certain food products within the European Union under controlled limits.

However:

• It is NOT listed as an FDA-approved color additive under 21 CFR Parts 73 or 74.
• It is NOT permitted for food, pharmaceutical, or cosmetic use in the United States.
• This product is classified strictly as NON-FDA Industrial Grade.

This distinction ensures regulatory clarity for U.S.-based businesses.

Why Choose Carmoisine Powder?

✔ Excellent water solubility
✔ Strong red hue with high tinting efficiency
✔ Uniform dispersion in aqueous formulations
✔ Stable under typical industrial processing
✔ Cost-effective bulk coloring option

If you’re formulating industrial cleaning liquids, soap bars, or laboratory tracing solutions where visual identification matters, Carmoisine delivers consistent red intensity without altering base formulation performance.

Common Non-Regulated Applications

• Soap and detergent coloration
• Industrial cleaning products
• Laboratory tracer dyes
• Textile research
• Paper and pulp research
• Technical product identification

Performance Characteristics

• Highly soluble in water
• Stable under neutral to mildly acidic conditions
• Avoid prolonged exposure to extreme alkaline environments
• Good thermal stability in standard processing
• High chromatic strength

Handling & Safety Guidelines

As a synthetic azo dye:

• Avoid inhalation of dust
• Wear gloves and protective eyewear
• Use in ventilated areas
• Keep sealed to avoid moisture absorption
• Refer to SDS prior to industrial handling

Although toxicological evaluations exist internationally, this grade is not certified for ingestion or topical regulated applications in the U.S.

Storage Conditions

• Store below 30°C
• Protect from humidity
• Keep container tightly sealed
• Avoid oxidizing chemicals
• Shelf life: 24–36 months under proper storage
