Methylchloroisothiazolinone
Methylchloroisothiazolinone appears in 17 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
Methylchloroisothiazolinone appears in 17 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.
What this page can and cannot answer
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 4 of 17 records have some flagged component, while the rest do not. Compare All-Purpose Cleaner; Essentials Liquid Hand Soap; Moisture Renewal Blend Body Wash to see how surrounding formulations change; do not assign their 75–100 score range to Methylchloroisothiazolinone itself. The ingredient most often sits near the end of the captured list, and Hair-conditioner supplies the most useful like-for-like starting point for a label review.
4 of 17 linked records have some flagged component
All 12 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 75–100 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.

- Typical depth in an ingredient list
- 81%
- Of the way down the captured list, averaged across the 17 products listing it (mean slot 19.1). Methylchloroisothiazolinone usually falls near the end of the captured 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.
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.
