Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Several studies are available in the scientific literature which investigated the biodegradation in water of tartaric acid and sodium tartrate. Almost all results support the ready biodegradation of these substances.
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 biodegradability of tartaric acid salts (i.e. monosodium, monopotassium, sodium potassium, sodium, potassium and calcium tartrate) may be assessed using also data specific for tartaric acid.
Overall, tartaric acid and its salts are deemed to be readily biodegradable in water.
The substance has been shown to be readily biodegradable. No further evaluation of its biodegradability is necessary.
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.
