Natural Red 4 has stirred curiosity across the food and cosmetic industries. You’ve seen it on ingredient labels, perhaps under different names, leaving you wondering if it’s just another additive or something far more complex. With roots in ancient traditions and ties to modern safety debates, this pigment carries more history—and controversy—than you might expect. But what truly lies behind the name? Let’s unravel the mystery.
Are Natural Red 4 and E120 the same thing?
Yes, Natural Red 4 and Carmine (E120) are the same thing — or more precisely, Natural Red 4 is the color index name (CI 75470), and E120 is the European food additive code for carmine, a natural red colorant derived from the cochineal insect (Dactylopius coccus).
What other names is Natural Red 4 known by?
Natural food colour red 4 is also known by several other names depending on the industry and regulatory system. Here’s a list of the most common alternatives:
| Name | Use Case / Industry | Region / Context |
|---|---|---|
| Natural Red 4 | Official Color Index name | Global (Cosmetics, Regulatory) |
| Carmine | Common commercial name | Global (Food, Cosmetics, Pharma) |
| Cochineal Extract | Broader insect-derived extract | Global (Natural Products) |
| E120 | EU food additive code | European Union (Food labels) |
| CI 75470 | Color Index Number for cosmetics | Global (INCI, Cosmetic labels) |
| Carminic Acid | Pure pigment compound | Scientific, Industrial use |
| Cochineal Carmine | Refined form of cochineal pigment | Regulatory documents |
| Crimson Lake | Historical/Artistic term (paint/textile) | Traditional painting and dyeing |
| Natural Red A | Scientific synonym | Research literature |
Is Natural Red 4 Approved for Use? A Look at FDA and EU Regulations
Yes, is approved worldwide — but not without strict rules. In the U.S., the FDA classifies it as a color additive (21 CFR 73.100), and the European Union labels it as E120. Products containing it must state so on the label due to allergy concerns. And no — it’s not considered vegan, kosher, or halal unless explicitly treated for those standards.

Could Carmine Be Made Without Bugs?
Scientists are exploring how to produce E120 without insects by using genetically modified microorganisms like Aspergillus nidulans. These lab-grown pigments could make carmine vegan-friendly and reduce environmental impact — although we’re still a few years from commercial use. Source: Chiang, Y.M. et al. (2010).

How Stable Is Natural Red 4 in Foods and Cosmetics?
E120 is one of the most stable natural colorants — resistant to heat, acid, and cold. But light? Not so much. That’s why it works great in yogurts, sausages, lipsticks, and pill coatings, but less so in sun-exposed beverages. Formulators love it for its vivid hue and shelf stability in processed goods.
