MICROBICS MICROTOXID TOXICITY TEST
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredtoas PFOS, FC-95, oras a component ofFX-3103. (1Octanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The 3M productionlotnumber was notnoted.The testsample isFX-3103, 3%. Currentinformationindicatesitisa mixtureof0.96%PFOS, 20% diethyleneglycolbutylether,50.56% water,15% ethyleneglycol4,.32% sodium octylsulfate6,.0% polyoxyethylenemonooctylphenylether,2.5% propane sultonefoarner,0.5% sodium nitrate0,.06% sodium laurylsulfate, and 0.1% benzotriazole.
The followingsummary applies to a mixture with incompletely characterizectconcentrations of impudties. Data may not accurately reflectthe toxicityof the fluorochemical component of the testsample.
