BIODEGRADATION (BOD/COD)
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonatmea;y also be referredtoas PFOS, FC-95, or as a component of FC-185F. (1Octanesulfoniaccid)(CAS # 2795-39-3)
Remarks: The 3M productionlotnumber was 1-2303. The testsample is FC-185F, cc 817-19. Currentinformationindicatesitisa mixtureof4% PFOS, 36% diethyleneglycolbutylether,29.29% water,14% ethyleneglycol, 8% Sultonefoamer,8.35% sodium octylsulfate0,.3% sodium laurylsulfate, and 0.06% tolyltriazole.
The followingsummary applies to a mixture with incompletely charactedzed concentrations of impuilties.Data may not accurately reflectthe biodegradabilityof the fluorochemical component of the test sample.
