Acid
Acid appears in 425 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
Acid appears in 425 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.
How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 105 of 425 records have some flagged component, while the rest do not. Compare 14 Grain Bread; 6 Chocolate Slices; Adobo Tamales Verdes to see how surrounding formulations change; do not assign their 0–100 score range to Acid itself. The ingredient most often sits in the lower half of the list, and Snacks supplies the most useful like-for-like starting point for a label review.
105 of 425 linked records have some flagged component
All 413 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.
High-volume listing for Acid - usage rank #1,150
- Usage rank
- #1,150
- of 247,206 ingredients that appear in at least one catalogued product, tied with 2 others that also appear in exactly 425 products, listed in more products than 99.5% of them.
- Typical depth in an ingredient list
- 56%
- Averaged label depth puts Acid in the lower half of the list (56% of list length, mean slot 14.3). Compound ingredients and OCR noise mean this cannot stand in for quantity.
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.
What else is usually in the same product as Acid
Across the 425 products on this site that list Acid, 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. Carrageenan shows up about 1.6x more often with Acid than in the catalogue at large.
| Additive | Shared products | Share of Acid products | Share of all products |
|---|---|---|---|
| Carrageenan | 31 | 7.3% | 4.5% |
| Sucralose | 26 | 6.1% | 2.7% |
| Acesulfame Potassium | 16 | 3.8% | 1.8% |
| Red 40 | 15 | 3.5% | 5.4% |
| Yellow 6 | 15 | 3.5% | 3.4% |
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.
How do the sampled products compare?
Each point is one of the 16 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.

Questions readers ask about Acid
Does Acid carry its own safety label in this catalog? ▼
This is a mixed neighborhood: some linked products carry a separate flag while others do not. This snapshot does not attach a standalone FDA/CSPI verdict to Acid. Compare like-for-like products before treating the average screening score as an ingredient verdict.
Which product shelves show up most often with Acid? ▼
Acid ranks in the top decile by product count (#1,150 of 247,206), appearing in 425 indexed products led by Snacks. The sample list below is a slice of that footprint, not the full universe.
Why is Acid so common on ingredient lists? ▼
