MICROBICS MICROTOXO TOXICITY TEST TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may also be referredtoas PFOS, FC-95, oras a component ofFX-3104. (1Octanesulfoniaccid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was notnoted.The testsample isFX-3104, 6%. Currentinformatioinndicatesitisa mixtureof0.48% PFOS, 14.09% diethyleneglycolbutylether,59% water,17.6% ethyleneglycol, 1.44% sodium oetylsulfate4,% inhibito2r.,0% polyoxyethylene monooctylphenylether,1.25% propane sultonefoamer,0.03% sodium lauryl sulfatea,nd 0.1% benzotdazole. The following summary applies to a mixture with incompletely characterized concentrations of impuilties.Data may not accurately reflectthe toxicityof the fluorochomical component of the testsample.
