Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Reported EC50 > 100 mg/l for benzoate
Reported EC50 > 4 mg/l for Li
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 70 mg/L
Additional information
The benzoate reference is cited in UN Concise International Chemical Assessment Document 26 on Sodium Benzoate and other references confirm low toxicity to Daphnia and other invertebrates
As Lithium metal did have an effect on Daphnia with an EC25 of 3.33 mg/l, an EC50 of 4 mg/l is used to estimate the figure for lithium benzoate; at 6% by weight of Li, the EC50 of lithium benzoate is estimated as ca 70 mg/l
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.
