26 _ 06& T BIODEGRADATION (BOD/COD) TEST SUBSTANCE _________________________________________ Identity: A mixture containing perfluorooctanesulfonate; may also be referred to as PFOS, FC-95, or as a component of FC-185F. (1Octanesulfonic acid) (CAS # 2795-39-3) Rem arks: The 3M production lot number was 1-2303. The test sample is FC-185F, cc 817-19. Current information indicates it is a mixture of 4% PFOS, 36% diethylene glycol butyl ether, 29.29% water, 14% ethylene glycol, 8% Sultone foamer, 8.35% sodium octyl sulfate, 0.3% sodium lauryl sulfate, and 0.06% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability o f the fiuorochemical component o f the test sample. M E T H O D :________________________________________________________ Method: Not noted.
