Description of key information

Bis[C11-14-(branched and linear)-alkyl]aminium nonadecaoxohexatungstate (EC 700-718-0), based upon results from the surrogate substance, is  not readily biodegradable under the conditions of the modified Sturm test (NOTOX B.V., 2012). 

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

In an OECD 301 B study ("Ready Biodegradability: CO2 Evolution Test"), conducted according to GLP, reaction mass of bis(C11-14-alkyl, branched and linear)amine nonadecaoxo hexatungstate (the surrogate substance) was designated as not readily biodegradable (NOTOX B.V., 2012).
