C Blue No
C Blue No appears in 40 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
C Blue No appears in 40 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.

What this page can and cannot answer
Audit the co-occurring flags first
67.5% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify C Blue No as the trigger. Open records such as 803275014144; Coastal bay fruit slixes; Complete Multivitamin Adults and inspect which ingredient row carries the caution marker. The 88.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 55% average label depth helps locate the term when checking the package.
67.5% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 37 of 37 NOVA-tagged records. That describes the surrounding products, not the substance. For a useful comparison, hold category and processing level constant, then inspect which named component changes alongside the caution flag; otherwise the product mix will confound the ingredient question.
Next check: open the lowest-scoring linked formulation and locate the exact caution-marked component.

What else is usually in the same product as C Blue No
Across the 40 products on this site that list C Blue No, 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.
