Potassium perfluorohexanesulfonate

Description:
Potassium perfluorohexanesulfonate (PFHxS) is a synthetic chemical belonging to the class of perfluoroalkyl substances (PFAS), which are known for their unique properties, including high thermal stability and resistance to water, oil, and grease. It is characterized by a perfluorinated carbon chain, specifically a six-carbon backbone, with a sulfonate functional group that imparts its surfactant properties. PFHxS is typically used in various industrial applications, including as a surfactant in firefighting foams, coatings, and textiles, due to its ability to reduce surface tension. The compound is highly persistent in the environment and has been detected in water, soil, and biota, raising concerns about its potential health effects, including endocrine disruption and developmental toxicity. Regulatory scrutiny has increased due to its bioaccumulation potential and long half-life in living organisms. As a result, there is ongoing research into its environmental impact and the development of alternatives to mitigate its presence in ecosystems.
