The Primary Alternate Name: Tartrazine
Yellow 5 is a synthetic yellow food dye with several names, but its most common alternative name is tartrazine. This water-soluble azo dye is a bright lemon-yellow colorant derived from petroleum. The FDA approves its use in food, drugs, and cosmetics, where it imparts a vibrant color to a wide range of products.
Other Monikers for Yellow 5
In addition to tartrazine, Yellow 5 can be identified by other designations, which may vary depending on the country or product. Knowing these names is essential for consumers who wish to monitor or avoid the additive. The European Union, for instance, uses a specific 'E number' for food additives.
- FD&C Yellow No. 5: This official designation is used in the United States and is often listed on food, drug, and cosmetic packaging.
- E102: This is the E number for tartrazine in Europe.
- C.I. 19140: The Colour Index International number, which is used to classify dyes and pigments.
- Acid Yellow 23: Another name for the pure chemical compound.
Yellow 5 in Everyday Products
Tartrazine is a ubiquitous ingredient, often found in products where a lemon-yellow or green hue is desired. Food manufacturers value its stability and cost-effectiveness, while pharmaceutical companies use it for tablet and capsule identification. A non-exhaustive list of products containing Yellow 5 includes:
- Foods: Soft drinks, candy, chips, mustard, instant puddings, and many cereals.
- Beverages: Energy and sports drinks, as well as powdered drink mixes.
- Medications: A variety of over-the-counter and prescription drugs, including vitamins and antacids, may be colored with tartrazine.
- Cosmetics: Products such as liquid and bar soaps, moisturizers, perfumes, and some makeup contain the dye.
Health Considerations and Regulations
Concerns over the health effects of Yellow 5 have led to regulatory differences worldwide and ongoing public debate. While the FDA considers it safe for general use in approved quantities, some regions and sensitive individuals have different perspectives. For example, some studies suggest a link between artificial food dyes and hyperactivity in children, though evidence is often inconclusive and controversial.
Some countries and regions have stricter regulations or bans. In the European Union, for example, products containing tartrazine must carry a warning label indicating potential effects on activity and attention in children. By contrast, Austria and Norway have historically banned or restricted the dye. People with aspirin sensitivity or those with certain allergic predispositions are more likely to experience reactions to Yellow 5, including hives and asthma.
Natural Alternatives to Yellow 5
As a response to consumer demand for natural ingredients, many manufacturers have begun substituting Yellow 5 with natural alternatives. These natural colorants provide a similar shade without the synthetic chemical composition.
Comparison Table: Yellow 5 vs. Natural Alternatives

How to Avoid Yellow 5 (Tartrazine)
For those concerned about consuming Yellow 5, checking ingredient labels is the most effective strategy. Look for “Tartrazine,” “FD&C Yellow No. 5,” or “E102” on packaging. Many brands now offer products explicitly labeled “no artificial colors” or “dye-free.” Choosing fresh, whole foods and reducing the consumption of highly processed items also significantly lowers exposure.
Conclusion: Yellow 5, Tartrazine, and the Informed Consumer
Yellow 5, or tartrazine, is a widely used and inexpensive artificial food coloring that provides a bright, stable yellow hue to countless products. Despite its widespread use, consumers should be aware of its various names and potential health concerns, particularly for those with sensitivities or allergies. By checking ingredient lists and considering natural alternatives, consumers can make more informed choices about the products they purchase.
