Registration Dossier
Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Tartaric acid and its salts (e.g. Calcium tartrate) are not expected to be toxic to FISH.
- LC50 (fish, 96h, OECD203): >100 mg/L used as key study
- LC50 (Fish, 96 hr, ECOSAR) = 506 g/L used as supporting study
- LC50 (Fish (SW), 96 hr, ECOSAR) = 884 g/L used as supporting study
Key value for chemical safety assessment
Additional information
LC50 values higher than 100 mg/L were predicted for tartaric acid by valid QSAR models.
Based on the assumption that in dilute aqueous conditions of defined pH, a salt will be fully dissociated and will behave no differently to the parent acid at identical concentration of the particular speciated form present, the aquatic toxicity of tartaric acid salts (i.e. monosodium, monopotassium, sodium potassium, sodium, potassium and calcium tartrate) may be assessed using data specific for tartaric acid. Therefore, also the tartaric acid salts are deemed to be non-toxic to fish.
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.
