Description of key information

(48 h ) EC50 7 mg/L D. magna (fw)
(96 h) LC50 4.6 mg/L C. crangon (m)

Key value for chemical safety assessment

Additional information

No data is currently available for alcohols, C9 -C11 (odd numbered), branched and linear, however data are available for C11 and C9 -C11 multi-constituent analogue.

A 96 h LC50 value of 0.8 -1.1 mg/L has been determined for the effect of undecanol on the mortality of the brackish water invertebrate Nitocra spinipes.

A reliable 48 h EC50 value of 7 mg/L has been determined for the effects of Alcohols, C9-11-linear and branched on the immobility of the freshwater invertebrate Daphnia magna.

A reliable 96 h LC50 value of 4.6 mg/L has been determined for the effects of Alcohols, C9-11-linear and branched on the mortality of the marine invertebrate Crangon crangon. This study has been selected as key as it is the only reliable value available for short-term toxicity to aquatic marine invertebrates.

Another reliable study reports a 48 h EC50 value of 8.5 mg/L with the freshwater invertebrate D. magna for Alcohols, C9 -C11 linear and branched.

These data are read-across to alcohols, C9 -C11 (odd numbered), branched and linear.
