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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Key value for chemical safety assessment
Additional information
The available in vitro tests (SOS chromotest, Ames test and Chromosome aberration test with sodium carbonate) were negative.
When the pH will be kept below 8 to have a good functioning biological test system, mainly bicarbonate will be available. Furthermore, sodium bicarbonate is naturally present in cells and both the structure of sodium bicarbonate and sodium carbonate do not indicate a genotoxic potential. Therefore, there is no reason to evaluate the potential genotoxicity of sodium carbonate further and no genotoxic effects are expected.

Short description of key information:
Sodium carbonate is not considered to be genotoxic based on
available information on the analogous substance sodium bicarbonate
(Ames Test with negative result; Ishidate et al, 1984).
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Based on the available information, no classification for genetic toxicity is required in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No.1272/2008.
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.
