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 and adverse effects are lacking up to and including the respective OECD/EC guidelines limit concentrations.
Benzoic acid: Reliable acute aquatic toxicity data of benzoic acid are available from guideline studies for daphnia. The lowest EC50 value is estimated with > 100 mg/L. In sum, benzoic acid has a low potential for acute 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 acute aquatic toxicity data are available from guideline studies for daphnia; the lowest EC50 value is estimated with > 116.6 mg/L. In sum, calcium dibenzoate has a low potential for acute toxicity to aquatic invertebrates.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
