AR&26 _ 069] BIODEGRADATION (BOD/COD) IESTsuBSTAN 000C 0 E Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-85 or as a component of FC-201AF. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not noted. The test sample is FC-201AF. Current information indicates it is a mixtureof 3% PFOS, 18.59% diethylene glycol butyl ether, 37.81% water, 14% ethylene glycol, 8.25% Acrylic foamer, 8% sodium octyl sulfate, 0.3% sodium lauryl sulfate, 3% triethanolamine, 6% sulfonated alkyl ether salts, and 0.05% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data may not accurately reflect the biodegradability of the fluorochemical component of the test sample.
