Sodium perfluorooctanoate is a fluorinated compound. Sodium perfluorooctanoate consists of a perfluorooctanoic acid (PFOA) backbone with a sodium ion replacing the hydrogen of the carboxyl group, enhancing its solubility in water. As a surfactant, it reduces surface tension, enabling it to interact effectively with both organic and inorganic materials. Sodium perfluorooctanoate has been utilized in various industrial processes, including the production of fluoropolymers and in other applications requiring stable, high-performance surfactants.
