Description and Uses
Perfluorohexane sulfonate is a six-carbon compound in the perfluoroalkyl family of chemicals. Perfluorohexane sulfonate was once used in firefighting foam and carpet treatment solutions. It was once widely used by 3M as a stain and water repellent but was phased out due to U.S. Environmental Protection Agency regulations. Much like other perfluoroalkyls, PFHxS can persist in the environment.
