Source-backed answer

- Of the way down the captured list, averaged across the 240 products listing it (mean slot 13.7). Calcium Hydroxide usually falls in the lower half of the list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.
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
Use prevalence before concern
Only 15% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Calcium Hydroxide spans 101 named brands and is led by the Plant-based foods and beverages group. Start with 100% orange juice; 100% Orange Juice; 100% Orange Juice when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 96.5/100 product average proves this ingredient safe.
101 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 133 of 226 classified products, leaving a meaningful remainder elsewhere. This breadth is why the page reports label depth, category, and product examples separately. Those dimensions help locate comparable products; combining them into a stronger safety claim would hide the variation the catalog actually contains.
Next check: compare label position across two brands before treating prevalence as equivalent exposure.
What else is usually in the same product as Calcium Hydroxide
Across the 240 products on this site that list Calcium Hydroxide, 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.
| Additive | Shared products | Share of Calcium Hydroxide products | Share of all products |
|---|---|---|---|
| Red 40 | 12 | 5% | 5.4% |
| Carrageenan | 10 | 4.2% | 4.5% |
| Yellow 5 | 8 | 3.3% | 4.8% |
| Caramel Coloring | 7 | 2.9% | 5.7% |
| Azodicarbonamide | 5 | 2.1% | 0.2% |
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.
