The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The EC50 (daphnia) for bis[C11-14-(branched and linear)-alkyl]aminium nonadecaoxohexatungstate (EC 700-718-0), based upon results from the surrogate substance, is 4.6 mg/l WAF.

Key value for chemical safety assessment

Effect concentration:
4.6 mg/L

Additional information

In an OECD 202 study (Daphnia sp. Acute Immobilisation Test), conducted according to GLP, reaction mass of bis(C11-14-alkyl, branched and linear)amine nonadecaoxo hexatungstate (the surrogate substance) did not induce acute immobilisation of Daphnia magna exposed to a Water accommodated fraction (WAF) prepared at a loading rate of 4.6 mg/l after 48 hours of exposure. Analyses showed that this corresponded to an average exposure concentration of 4.0 micro g/l (NOEC). The 48h-EC50 is between concentrations present in WAFs prepared at loading rates of 4.6 and 10 mg/l. The 48h-EC50 based on average exposure concentrations is 19 micro g/l (95% confidence interval between 14 and 30 micro g/l) (NOTOX, 2012).
