6:2 FTS

Synonyms: 6:2 Fluorotelomer sulfonic acid

CAS Number: 27619-97-2

Sources of exposure:

Firefighting foam; metal plating; industrial surfactants; treated paper and textiles; contaminated water and soil

Description:

6:2 FTS is a fluorotelomer per- and polyfluoroalkyl substance (PFAS) used as an alternative to PFOS-based chemicals in some firefighting foams, metal-plating mist suppressants, industrial surfactants, coatings, paper products, and textiles. It may enter the environment through product use, industrial discharges, firefighting activities, and the disposal of PFAS-containing waste. Although 6:2 FTS is sometimes described as a replacement PFAS, it is persistent and can transform into other persistent PFAS, including shorter-chain perfluoroalkyl carboxylic acids. Information about its long-term health effects and those of its transformation products remains limited. 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:

Organ System Toxicity

May cause organ damage and disease.

Irritant

May cause skin, eye, or respiratory irritation.

Banned/restricted lists:

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.
