OCTANOL/WATER PARTITION COEFFICIENT
TEST SUBSTANCE
Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, FC116, FC-126, FC-169, or FC-143. (Octanoicacid, pentadecafluoro-, ammonium salt, CAS # 3825-26-1)
Remarks: The 3M production lot number was not recorded. The subject compound is FC-143. It's purity was not sufficiently characterized, though current information indicates it is a mixture of 96.5 -100% test substance and 0 - 3.5% C6, C7, and Cg perfluoro analogue compounds.
METHOD
Method: Calculation GLP (Y/N): No Year com pleted: 1981 Remarks: Manual calculation using a published method for determining partition coefficients based on chemical fragments / functional groups.
RESULTS
Calculated logP0wfor FC-143 = -0.9
CONCLUSIONS
This calculation indicates that ammonium perfluoroocanoate (FC-143) has an octanol / water partition coefficient of approximately 0.126.
