Alginate

Alginate carries a source-backed screening score of 5/5 and appears in 47 indexed US food products. CSPI rates it “Safe.”

Source-backed answer

Alginate appears in 47 catalogued products. CSPI rates it “Safe.” No FDA SAFFA status is attached. Those source labels describe the ingredient; they do not establish whether a particular product, dose, allergy, or diet is safe.

Mean relative depth 66% across 47 parsed labels, slot 23.6 on average. Alginate tends to sit in the lower half of the list. Depth is location on the label, not a measured dose.

Computed from parsed product ingredient lists (Open Food Facts). The ranking covers 247,206 ingredients that appear at least once. Neither usage rank nor label depth is a safety clearance.

Reading this ingredient record

Audit the co-occurring flags first

61.7% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Alginate as the trigger. Open records such as 2 Layer Cake; 2 Layer Italian Cream Cake; Apple strudel and inspect which ingredient row carries the caution marker. The 77.1/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 66% average label depth helps locate the term when checking the package.

61.7% of linked products contain a separately flagged ingredient

Processing is unusually concentrated here: Group 4 accounts for 42 of 47 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 Alginate

Across the 47 products on this site that list Alginate, 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. Polysorbate 60 shows up about 19.8x more often with Alginate than in the catalogue at large.

Co-occurrence describes what manufacturers formulate together. It is not a claim that these additives interact, and it carries no regulatory meaning. Counted over products with parsed ingredient lists; Open Food Facts, 2026-09-01.

Frequently Asked Questions

How should I read safety signals when Alginate sits in heavily flagged products?

61.7% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Alginate is the trigger. Where a source rating exists, Alginate scores 5/5 on this site's screening scale and CSPI lists it as "Safe". None of that replaces a product-, dose-, allergy-, or person-specific determination.

Which product shelves show up most often with Alginate?

Alginate ranks in the top decile by product count (#5,176 of 247,206), appearing in 47 indexed products led by Snacks. The sample list below is a slice of that footprint, not the full universe.

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

Alginate is recorded as a thickener 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.
