AR9.A 6 - $ l 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-3104. (1Octanesulfonic acid) (CAS # 2795-39-3). Rem arks: The 3M production lot number was not noted. The test sample is FX-3104. Current information indicates it is a mixture of 0.48% PFOS, 14.09% diethylene glycol butyl ether, 59% water, 17.6% ethylene glycol, 1.44% sodium octyl sulfate, 4% inhibitor, 2.0% polyoxyethylene monooctylphenyl ether, 1.25% propane sultone foamer, 0.03% 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.
