Re40
Re40 appears in 1 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
Re40 appears in 1 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 Re40 as the trigger. Open records such as Sour Patch Kids Watermelon and inspect which ingredient row carries the caution marker. The 10.0/100 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 1 of 1 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.

Frequently Asked Questions
How should I read safety signals when Re40 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 Re40 is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Where does Re40 show up across the catalog? ▼
Re40 sits above the median for catalog prevalence (1 products, #71,300 of 247,206) across 1 named brands. Category mix varies — use the linked records rather than treating any single shelf as representative.
Why is Re40 so common on ingredient lists? ▼
The current source record does not specify a technical effect for Re40. Its near the end of the captured list and product examples are shown without guessing why manufacturers include it.
