TOXICITY TO AQUATIC PLANTS TEST SUBSTANCE Identity:A mixturecontainingperfluorooetanesulfonatweh,ich may alsobe referredtoas PFOS, FC-95, or as a component of FC-3017. (1Octanesulfoniaccid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was notnoted. The testsample isFC-3017. CurrentinformationindicatesFC-3017 isa mixtureof0.67% PFOS, 20% diethyleneglycolbutylether,55.41% water,21% ethyleneglycol, 1.33% Hydroxy foamer,1% sodium octylsulfate0,.5% polyoxyethylene monooctylphenylether,0.04% sodium laurylsulfatea,nd 0.05% tolyltraizole. The followingsummary applies to a mixture with incompletely characterizedconcentrations of impurities.Data may not accurately reflecttoxicityof the tluorochemical component of the testsample. METHOD: Method: OECD Guideline201 and EPA CFR 40 797.1050.
