Bring precision and vivid blue coloration to your industrial and laboratory formulations with Brilliant Blue FCF Powder (CI 42090, E-133) — a high-performance synthetic triarylmethane dye known for its intense chromatic strength and excellent aqueous solubility.

Brilliant Blue FCF is chemically identified as C37H34N2Na2O9S3, a disodium salt with strong light absorption around 628–631 nm. Its brilliant hue, stability in neutral pH systems, and high solubility make it ideal for controlled, non-consumable applications.

Important Regulatory Clarification

Although Brilliant Blue FCF is listed by the FDA as FD&C Blue No. 1 when properly certified, this specific product is classified as Non-FDA Grade.

That means:

It is NOT batch-certified under FDA color additive requirements.
It is NOT intended for food, beverage, drug, or cosmetic manufacturing in the United States.
It is strictly for industrial, research, laboratory, and technical applications.

Using non-certified dye in regulated consumables violates U.S. federal law. Always verify grade and certification before regulatory use.

Technical Performance Advantages

✔ High water solubility
✔ Strong tinting power
✔ Uniform dispersion in aqueous systems
✔ Stable under typical processing temperatures
✔ Compatible with glycol and mild solvent systems

Typical Non-Regulated Applications

Imagine formulating a research solution where color contrast is critical for visual tracking — Brilliant Blue FCF provides consistent, reliable visual intensity even at low concentrations.

Handling & Safety

As a fine synthetic dye powder:

Avoid inhalation of airborne particles.
Wear gloves, protective eyewear, and dust mask.
Use in well-ventilated environments.
Store in sealed, moisture-resistant containers.
Refer to SDS before handling.

Although toxicological assessments (EFSA/JECFA) support safety within regulated intake levels, this grade is not certified for ingestible use.

Storage Recommendations

Store below 30°C
Protect from humidity
Keep sealed to prevent contamination
Avoid strong oxidizing agents
