IEstsusstANCE
000000000
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, 1,1122,334,4556,6,7,7,88,8-
heptadecafluoro-, potassium salt, CAS # 2795-39-3)
Remarks: The 3M production lot number was not noted. Thetest
sample is FC-600 (Belgium). 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 %tolyltriazole.
