Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data relating to benzoate salts and lithium salts have been considered to set a potential PNEC.

The effects of benzoic acid, sodium benzoate and lithium salts have been considered in this review and algea appear to be more sensitive than either fish or Daphnia. The algal data have been used to set the PNEC.

The toxicity to sodium benzoate (IC50 30 mg/l) appears significantly greater than the toxicity of benzoic acid, suggesting that the sodium itself may be leading to reduction in growth rate.

The toxicity of lithium was estimated from different sources, with the lowest reliable IC50 of approximately 12 mg/l Li

It is considered conservative to use the IC50 of 30 mg/l to set a figure for estimating PNEC.

Conclusion on classification

In view of the reported levels of toxicity (range 10 - 100 mg/l for acute exposure) and in view of the rapid biodegradation, classifciation is not considered necessary.
