Ad slug - 0707 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 FC-201F-X. (1Octanesulfonic acid) (CAS # 2795-39-3). Rem arks: The 3M production lot number was 1. The test sample is FC201F-X (F -11129). Current information indicates it is a mixture 3% PFOS, 36% diethylene glycol butyl ether, 36.6% water, 8.25% acrylic foamer, 7% sodium octyl sulfate, 6% sulfonated alkyl ether salts, 3% triethanolamine, and 0.15% toluoltriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability o f the ftuorochemicai component o f the test sample.
