CI 19140: Tartrazine
Also Known As:
- Tartrazine
- FD&C Yellow 5
- E102 (in Europe)
- Acid Yellow 23
- Food Yellow 4
What is it? CI 19140, commonly known as Tartrazine, is a synthetic lemon yellow azo dye. It is widely used as a colorant in various industries, including food, cosmetics, and pharmaceuticals. Its chemical formula is C16H9N4Na3O9S2, and it is known for its bright yellow hue.
What Makes it Different? Tartrazine is notable for its vibrant yellow color, which can be mixed with other dyes to create a range of colors. It is highly soluble in water and glycerine, making it versatile for different applications. Its synthetic origin allows for consistent quality and color intensity.
Where Does it Come From? Tartrazine is a synthetic dye, meaning it is manufactured through chemical processes rather than being derived from natural sources. This synthetic production ensures a stable supply and uniformity in its properties.
Where is it Used?
- Food Industry: Used to color beverages, candies, desserts, and processed foods.
- Cosmetics: Found in products like eyeshadows, foundations, lipsticks, shampoos, and lotions.
- Pharmaceuticals: Used to color pills and syrups.
- Textiles: Employed in dyeing fabrics like wool and silk.
Is it Sustainable? The sustainability of CI 19140 is a complex issue. While its synthetic nature ensures a consistent supply, it also raises concerns about environmental impact and health safety.
Sustainable Issues Related to its Production:
- Environmental Impact: The production of synthetic dyes like Tartrazine involves chemical processes that can result in the release of harmful byproducts into the environment. Proper waste management and treatment are crucial to mitigate these effects.
- Health Concerns: Although generally considered safe, some individuals may experience allergic reactions to Tartrazine. Regulatory bodies have set specific purity criteria to ensure its safety in consumer products.
- Resource Use: The production of synthetic dyes requires raw materials, energy, and water, contributing to the overall environmental footprint. Efforts to improve the efficiency of these processes and develop greener alternatives are ongoing.
In summary, while CI 19140 (Tartrazine) is a widely used and effective colorant, its production and use come with sustainability challenges that need to be addressed through responsible manufacturing practices and regulatory oversight.
