BIODEGRADATION (BOD/COD)
TEST SUBSTANCE
Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95 or as a component of FC-201AF. (1Octanesulfonic acid) (CAS # 2795-39-3).
Rem arks: The 3M production lot number was not noted. The test sample is FC-201AF (L-13652). Current information indicates it is a mixture of 3% PFOS, 18.59% diethylene glycol butyl ether, 37.81% water, 14% ethylene glycol, 8.25% Acrylic foamer, 9% sodium octyl sulfate, 0.3% sodium lauryl sulfate, 3% triethanolamine, 6% sulfonated alkyl ether salts, and 0.05% tolyltriazole.
The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability o f tine fluorochemical component o f the test sample.
