Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 are not expected to be toxic to microorganisms.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
A IGC50 value higher than 1000 mg/L was predicted for tartaric acid by a valid QSAR model. As a supplement to it, no toxic effect to (sludge) microorganism was observed in the biodegradation tests on tartaric acid and disodium tartrate.
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 aquatic microorganisms.
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.
