ACUTE TOXICITY TO FISH (FATHEAD MINNOW) JEST~S ~ UBSTANCE
Identity: Mixture containing perfluorooctanesulfonate which may also be
referred to as PFOS, FC-85, or as a component of FC-203FC. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not noted. The test sample is FC-203FC. Current information indicates it is a mixture of 0.85% PFOS, 17% diethylene glycol butyl ether, 74.46% water, 2.34% acrylic foamer, 1.7% alkyl ether sulfate, 2.55% sodium octyl sulfate, 0.12% sodium nitrite,0.09% sodium molybdate, 0.85% triethanolamine, and 0.04% tolyltriazole.
The following summary applies to a mixture with incompletely characterized concentrationsof impurities. Data may not accurately
reflect toxicity of the fluorochemical component of the test. sample.
