Reading this ingredient record
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 2610 of 6399 records have some flagged component, while the rest do not. Compare 0016500579793; 1 mg melatonin; 1,000mg Vitamin C Pink Lemonade to see how surrounding formulations change; do not assign their 0–100 score range to Silicon Dioxide itself. The ingredient most often sits in the lower half of the list, and Plant-based foods and beverages supplies the most useful like-for-like starting point for a label review.
2610 of 6,399 linked records have some flagged component
All 6311 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 Silicon Dioxide
Across the 6,399 products on this site that list Silicon Dioxide, 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 2.4x more often with Silicon Dioxide than in the catalogue at large.
| Additive | Shared products | Share of Silicon Dioxide products | Share of all products |
|---|---|---|---|
| Caramel Coloring | 860 | 13.4% | 5.7% |
| Sucralose | 737 | 11.5% | 2.7% |
| Yellow 5 | 399 | 6.2% | 4.8% |
| Acesulfame Potassium | 345 | 5.4% | 1.8% |
| Red 40 | 334 | 5.2% | 5.4% |
