Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic toxicity studies with calcium dibenzoate are not available, thus aquatic toxicity will be addressed with existing data on the dissociation products.


 


Calcium: Calcium as an essential element has a very low potential for toxicity to freshwater and saltwater invertebrates.


 


Benzoic acid: Reliable chronic aquatic toxicity data of benzoic acid are available from guideline studies for daphnia. The lowest 21-d NOEC value amounts to 25 mg/L. In sum, benzoic acid has a low potential for chronic toxicity to aquatic invertebrates.


 


Calcium dibenzoate: Using existing aquatic toxicity data of the dissociation products of calcium dibenzoate, the aquatic hazard assessment is based on the most toxic moiety, i.e. the benzoate anion. Existing aquatic toxicity data of benzoic acid are recalculated for calcium dibenzoate based on a maximum benzoate content of 85.8 %. Reliable chronic aquatic toxicity data are available from guideline studies for daphnia; the lowest EC50 value amounts to 29.1 mg/L. In sum, calcium dibenzoate has a low potential for chronic toxicity to aquatic invertebrates.
