Description:

N-MeFOSAA is a per- and polyfluoroalkyl substance (PFAS) associated with older PFOS-based stain-, grease-, and water-resistant treatments. It may be released from treated carpets, textiles, upholstery, food-contact materials, and other consumer products or formed through the breakdown of related precursor chemicals. N-MeFOSAA is environmentally persistent and can transform into PFOS, a highly persistent and bioaccumulative PFAS with well-documented health concerns. The health effects of N-MeFOSAA itself have not been studied as extensively as those of PFOS. Because this PFAS is environmentally persistent and may contribute to sustained human or ecological exposure directly or through transformation products, the glossary applies a precautionary approach where long-term hazard and exposure information is limited.

Health concerns:

No specific health concerns have been flagged for this chemical.

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
