Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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.

Additional information
PNECs have been derived for freshwater, marine water, and the STP using the available endpoints. The PNECs were calculated using endpoints obtained using freshwater aquatic species and STP microorganisms. PNEC values for sediment and soil were derived by the equilibrium partitioning method (EPM). No PNECs were calculated for air, or secondary poisoning as they are deemed to be unnecessary.
PNEC freshwater = 0.0032 mg/L
PNEC marine water = 0.0003 mg/L
PNEC STP = 100 mg/L
PNEC sediment (freshwater) = 2.043 mg/kg dw
PNEC sediment (marine) = 0.204 mg/kg dw
PNEC soil = 0.406 mg/kg dw
Conclusion on classification
Based on data summarised here benzyl benzoate is classified for acute category 1 toxicity as the ErC50 for algae is less than 1 mg/L.
As benzyl benzoate is rapidly degradable it is classified for chronic category 2 toxicity, since EC10 for fish is > 0.01 mg/L and < 0.1 mg/L, which is also established in the CLP harmonised classification.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
