BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredto as PFOS, FC-95, or as a component of FC-203A. (1Octanesulfoniaccid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was notprovided.The test sample isFC-203A. Currentinformationindicatesitisa mixtureof 1.34% PFOS, 25% diethyleneglycolbutylether,67.85% water,2.66% Sultone foamer, 3% sodium octylsulfate0,.1% sodium laurylsulfatea,nd 0.05% tolyltriazole. The followingsummary applies to a mixture with incompletely characterized concentrations of impuritfes.Data may not accurately reflectthe biodegradabilityof the fluoruchemical component of the test sampie.
