C Blue # 1

C Blue # 1 appears in 2 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 # 1 appears in 2 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.

How to use this page

Audit the co-occurring flags first

100% 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 # 1 as the trigger. Open records such as Great Value Holiday Mini Chippers; great value and inspect which ingredient row carries the caution marker. The 90.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 89% average label depth helps locate the term when checking the package.

100% of linked products contain a separately flagged ingredient

Processing is unusually concentrated here: Group 4 accounts for 2 of 2 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.

C Blue # 1 — common follow-ups

How should I read safety signals when C Blue # 1 sits in heavily flagged products?

100% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming C Blue # 1 is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.

Where does C Blue # 1 show up across the catalog?

C Blue # 1 sits above the median for catalog prevalence (2 products, #46,185 of 247,206) across 1 named brands. Category mix varies — use the linked records rather than treating any single shelf as representative.

Why is C Blue # 1 so common on ingredient lists?

The current source record does not specify a technical effect for C Blue # 1. Its near the end of the captured list and product examples are shown without guessing why manufacturers include it.
