Identity: Mixture containing perfluorooctanesulfonate which may also be referred to as PFOS, FC-95,or as a component of FC-203FC. (1-
Octanesulfonic acid) (CAS # 2795-39-3).
Remarks: The 3M production lot number was not noted. The test sample
is FC-203FC, identified by the laboratory as R1335. 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.
