BIODEGRADATION (BOD/COD) TEST SUBSTANCE________________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FX-3103. (1Octanesulfonic acid) (CAS # 2795-39-3). Rem arks: The 3M production lot number was not noted. The test sample is FX-3103, 3%. Current information indicates it is a mixture of 0.96% PFOS, 20% diethylene glycol butyl ether, 50.56% water, 15% ethylene glycol, 4.32% sodium octyl sulfate, 6.0% polyoxyethylene monooctylphenyl ether, 2.5% propane sultone foamer, 0.5% sodium nitrate, 0.06% sodium lauryl sulfate, and 0.1% benzotriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability o f the fluorochemical component o f the test sample. METHOD:________________________________________________________ Method: Not noted.
