Polyisobutene
Polyisobutene appears in 7 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
Polyisobutene appears in 7 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.

Catalog prevalence comes from Open Food Facts ingredient lists. FDA SAFFA and CSPI Chemical Cuisine labels are shown only when the source record contains them.
Reading this ingredient record
Audit the co-occurring flags first
57.1% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Polyisobutene as the trigger. Open records such as Black Cherry Merlot; UV Clear; UV Daily and inspect which ingredient row carries the caution marker. The 64.4/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 28% average label depth helps locate the term when checking the package.
57.1% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 6 of 6 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.
Polyisobutene sits in the busiest tenth of the catalog (#16,390 / 247,206)
- Usage rank
- #16,390
- of 247,206 ingredients that appear in at least one catalogued product, tied with 1,423 others that also appear in exactly 9 products.
- Typical depth in an ingredient list
- 28%
- Of the way down the captured list, averaged across the 9 products listing it (mean slot 10.0). Polyisobutene usually falls in the upper half of the list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.
Ranks use Open Food Facts ingredient rows on this site’s refresh cycle. 247,206 ingredients with ≥1 product appearance enter the ranking. Prevalence and list depth are catalog facts, not toxicology.
How do the sampled products compare?
Each point is one of the 7 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.

Polyisobutene — common follow-ups
How should I read safety signals when Polyisobutene sits in heavily flagged products? ▼
57.1% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Polyisobutene is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Which product shelves show up most often with Polyisobutene? ▼
Polyisobutene ranks in the top decile by product count (#16,390 of 247,206), appearing in 7 indexed products led by Sunscreen. The sample list below is a slice of that footprint, not the full universe.
Why is Polyisobutene so common on ingredient lists? ▼
The source record does not name a technical effect, yet Polyisobutene appears in 7 products (#16,390 usage rank). High prevalence here describes formulation frequency, not an approved use level.
