What Is Erythrosine: Are They Safe For Humans?
Introduction
Food colorants play a crucial role in enhancing the visual appeal of everyday consumables, from bright red candies to pink cake icings.
These additives make products more attractive and can influence consumer perception and taste experience. Among the many colorants used today, erythrosine stands out for its distinctive cherry-pink hue and widespread application.
But what is erythrosine, and why is it used so frequently in processed foods and pharmaceuticals?
What Is Erythrosine?
Erythrosine, or FD&C Red No. 3 or E127, is a synthetic red dye commonly used in food, cosmetics, and pharmaceuticals. Chemists classify it under the xanthene class of dyes and recognize it for its bright pink to cherry-red color.
Erythrosine is a food dye derived from fluorone. Its chemical structure contains iodine, which gives it a unique appearance compared to other food dyes.
As a water-soluble compound, erythrosine is particularly effective in products that require uniform color distribution. Manufacturers have used it for decades and continue to choose it across various industries, though it still faces its share of scrutiny.

Uses of Erythrosine
Erythrosine serves multiple purposes across different sectors:
Food Industry
- Widely used to color candies, popsicles, cake decorations, and maraschino cherries
- Sometimes found in processed snacks and beverages, although usage has declined due to health debates
Pharmaceuticals
- Used to color tablets, capsules, and oral care products like mouthwashes
- Helps in product identification and branding
Cosmetics
- Incorporated in lipsticks, blushes, and nail polishes for its vivid pigmentation
Industrial and Laboratory Applications
- Employed as a biological stain in microscopy
- Useful in dental plaque disclosing tablets
The versatility of erythrosine stems from its stable coloration and compatibility with various formulations.
Safety and Regulatory Status
The safety of erythrosine has been a subject of global regulatory reviews:
- In the United States, the FDA permits its use in foods and drugs within specific limits, particularly for coloring externally applied drugs and cosmetics.
- Regulatory bodies in the European Union label it E127 and permit its use in limited applications, such as cocktail cherries and certain bakery decorations.
- Some countries, including Norway and Japan, have banned or restricted their use based on precautionary principles and earlier toxicological studies.
The World Health Organization (WHO) sets the Acceptable Daily Intake (ADI) at 0.1 mg/kg of body weight, suggesting that limited exposure is safe.
However, ongoing evaluations continue to assess its long-term impact, especially on vulnerable groups like children.
Conclusion
Erythrosine is a synthetic dye widely used for its vibrant red-pink color in food, cosmetics, and pharmaceuticals. While various regulatory bodies have approved it, concerns over its safety have led to bans or limitations in certain regions.
With increasing consumer awareness and demand for natural alternatives, the future of erythrosine in consumer products remains under review. Understanding erythrosine helps consumers make informed choices about the products they use and consume.
