Description of key information

In an OECD 202 test the medium effect concentration (EC50) for Quaternary ammonium compounds, tri-C8-10-alkylmethyl, chlorides after 48 h of exposure against Daphnia magna  based on the nominal loading rates was calculated to be 0.160 mg/l (95% confidence limits: 0.143–0.182 mg/l).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.16 mg/L
