Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

50°C: Hydrolysis rate constant k = 0.3464 d-1 ;DT50 = 2.0 d
pH 9:
20°C: Hydrolysis rate constant k = 0.0406 d-1 ;DT50 = 17.1 d
40°C: Hydrolysis rate constant k = 0.4860 d-1 ;DT50 = 1.4 d
50°C: Hydrolysis rate constant k = 1.3450 d-1 ;DT50 = 0.5 d
Key value for chemical safety assessment
Additional information
It can be concluded that the formation of 2-oxiranemethanesulfonicacid, sodium salt and sodium 2,3-dihydroxypropane-1-sulfonate is highly likely. Furthermore, sodium 2,3-dihydroxypropane-1-sulfonate seems to be the most stable transformation product and thus might be the endpoint of the degradation pathway. However, a detailed statement of the degradation pathway could not be provided.
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.
