Erythrosine

Introduce vibrant pink-red coloration into industrial and laboratory processes with Erythrosine (CI 45430, E-127) Non-FDA Water Soluble Dye Powder — a high-strength iodinated xanthene dye known for its brilliant bluish-pink hue and excellent solubility.

While erythrosine is internationally recognized as E-127 and known in regulated contexts as FD&C Red 3, this specific product is intentionally supplied and classified as NON-FDA grade. It is not certified, not batch-approved, and not intended for food, pharmaceutical, or cosmetic applications within the United States.

Instead, it is designed exclusively for:

✔ Industrial processes
✔ Technical manufacturing
✔ Laboratory research
✔ Analytical staining applications
✔ Educational demonstrations

What Makes Erythrosine Unique?

Erythrosine is an iodinated derivative of fluorescein. Its molecular structure contains four iodine atoms, which contribute to:

• Strong chromatic intensity
• Brilliant pink-red coloration
• Excellent water solubility
• High visibility even at low concentrations

Because it dissolves completely in water, it is suitable for aqueous technical systems where uniform coloration is required.

Important Regulatory Clarification

This product is sold strictly as NON-FDA grade:

• Not FDA batch certified
• Not approved for U.S. food use
• Not approved for drug applications
• Not approved for cosmetic use
• Not intended for ingestion

Even though erythrosine may be approved in certain regulatory frameworks globally, this SKU is marketed exclusively for non-regulated industrial and laboratory applications.

Typical Non-Regulated Applications

• Industrial colorant research
• Laboratory staining
• Analytical indicator studies
• Educational chemistry demonstrations
• Technical dye tracing

Imagine using a dye tracer in a lab experiment where vivid color contrast is required — erythrosine’s strong tint strength ensures immediate visual detection.

Technical Characteristics

• Highly water soluble
• Brilliant pink-red shade
• Strong tint strength
• Stable under controlled laboratory conditions
• Compatible with neutral aqueous systems

Avoid exposure to strong oxidizing agents.

Handling & Storage

• Avoid inhalation of powder dust
• Use gloves, mask, and protective eyewear
• Store in tightly sealed container
• Protect from light and humidity
• Shelf life: 24–36 months

Dispose according to local chemical waste regulations.
