BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:Mixturecontainingperfluorooctanesulfonawthei,ch may alsobe referredto as PFOS, FC-95,or as a component of FC-203CF-X or FC-203CF. (1-Octanesulfoniacid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was 101. The testsample isFC203CF. Currentinformatioinndicateistisa mixtureof1% PFOS, 20% diethyleneglycolmonobutylether,70.2% water,2.75% Acrylicfoamer,3% sodium octylsulfate1,% triethnaolamine, 2% sulfonatedalkylethersalts,and 0.05% tolyltriazole. The followingsummary appliesto a mixture with incompletely characterizedconcentrationsof impurities.Data does not accurately retlectthe degradation potentialof the fluorochemkal component of the testsample.
