How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 588 of 1717 records have some flagged component, while the rest do not. Compare 1/2 Cheese Pizza & 1/2 Pepperoni Pizza; 1/2 Loaf; 1/2 Loaf Butter White to see how surrounding formulations change; do not assign their 0–100 score range to Ammonium Sulfate itself. The ingredient most often sits near the end of the captured list, and Plant-based foods and beverages supplies the most useful like-for-like starting point for a label review.
All 1707 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 0–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.
Next check: pair one flagged product with a similar unflagged product from the same shelf category.
What else is usually in the same product as Ammonium Sulfate
Across the 1,717 products on this site that list Ammonium Sulfate, 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. Azodicarbonamide shows up about 74.5x more often with Ammonium Sulfate than in the catalogue at large.
| Additive | Shared products | Share of Ammonium Sulfate products | Share of all products |
|---|---|---|---|
| Azodicarbonamide | 255 | 14.9% | 0.2% |
| Caramel Coloring | 118 | 6.9% | 5.7% |
| Sodium Nitrite | 109 | 6.3% | 2.4% |
| Polysorbate 60 | 93 | 5.4% | 1.4% |
| BHT | 79 | 4.6% | 1.1% |
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, 2026-08-02.
