Blue # 1
Blue # 1 appears in 52 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer
Blue # 1 appears in 52 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Reading this ingredient record
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 23 of 52 records have some flagged component, while the rest do not. Compare Applesauce; Belgian White Chocolate; Dark Chocolate Covered Pretzels With Peppermint Candy to see how surrounding formulations change; do not assign their 70–100 score range to Blue # 1 itself. The ingredient most often sits near the end of the captured list, and Snacks supplies the most useful like-for-like starting point for a label review.
23 of 52 linked records have some flagged component
All 52 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 70–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.
Next check: pair one flagged product with a similar unflagged product from the same shelf category.

Derived by this site from the ingredient lists of every catalogued product (Open Food Facts), recomputed on each data refresh. 247,206 ingredients have at least one appearance and are ranked here. Usage and list position describe prevalence, not safety.
What else is usually in the same product as Blue # 1
Across the 52 products on this site that list Blue # 1, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set. Titanium Dioxide shows up about 8.2x more often with Blue # 1 than in the catalogue at large.
| Additive | Shared products | Share of Blue # 1 products | Share of all products |
|---|---|---|---|
| Titanium Dioxide | 9 | 17.3% | 2.1% |
| Sucralose | 6 | 11.5% | 2.7% |
Co-occurrence describes what manufacturers formulate together. It is not a claim that these additives interact, and it carries no regulatory meaning. Counted over products with parsed ingredient lists; Open Food Facts, 2026-09-01.
How do the sampled products compare?
Each point is one of the 16 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.
