What this page can and cannot answer

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 TBHQ as the trigger. Open records such as 10" egg custard pie; 2 Gringo's Chupacabra Rub, A Fine Meat Rub; 2 Peanut Butter Cups and inspect which ingredient row carries the caution marker. The 66.3/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 75% 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 1961 of 2011 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 TBHQ

Across the 2,019 products on this site that list TBHQ, 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. Caramel Coloring shows up about 3x more often with TBHQ than in the catalogue at large.

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.

TBHQ — common follow-ups

How should I read safety signals when TBHQ 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 TBHQ is the trigger. Where a source rating exists, TBHQ scores 1/5 on this site's screening scale and CSPI lists it as "Avoid" with FDA SAFFA status "Approved (preservative, 21 CFR 172.185)". None of that replaces a product-, dose-, allergy-, or person-specific determination.

Which product shelves show up most often with TBHQ?

TBHQ ranks in the top decile by product count (#402 of 247,206), appearing in 2,019 indexed products led by Snacks. The sample list below is a slice of that footprint, not the full universe.

What function does TBHQ serve when it appears beside other flagged additives?

TBHQ is recorded as a preservative in source technical-effect fields. In high co-flag products, that function coexists with other caution-marked components — inspect the full list rather than isolating this role.
