Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 aquatic plants and adverse effects are lacking up to and including the respective OECD/EC guidelines limit concentrations.

Benzoic acid: Only a supporting study is available that does not add significantly to the body of knowledge of substance effects on aquatic plants.


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. Since reliable toxicity data are not available for benzoic acid, a conclusion on the potential of calcium dibenzoate to affect aquatic plants cannot be derived.
