AR 226 -- 0835 ACUTE TOXICITY TO FISH (FATHEAD MINNOW) IEST~S ~UBSTANCE Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-600. (1-Octanesulfonic acid, 1,1,2,2,3,3.4,4,5,5,6,6,7.7.8,8,8heptadecafluoro-, potassium salt, CAS # 2795-39-3) Remarks: The 3M production lot number was 628. The test sample is FC-600 (US). Current information indicates it is a mixture of 1.0% PFOS, 81.20% water, 12.00% diethylene glycol butyl ether, 1.00% sodium octyl sulfate, 2.00% propane Sultone foamer, 1.00% sodium decyl sulfate, 0.85% xanthan gum, 0.1% N-(3-chloroallyl) hexaminium chloride, 0.80% starch, and 0.05 % benzotriazole. - The following summary applies to a mixture with incompletely characterized concentration of impurities. Data may not accurately reflect the toxicity of the fluorochemical component of the test sample. METHOD: Method: Not noted.
