The surface active properties of the potassium salt of PFOS make a direct determination of the octanol-water partition coefficient impossible. In a preliminary study reported by 3M an inseparable emulsion was formed. 3M determined the solubility of PFOS (K salt) in octanol as 56 mg/L, and calculated the log Kow from the ratio of solubilities, giving a log Kow value of -1.08.
