Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
At the three pH values tested, results from the preliminary test indicated that the half-life was greater than 5 days at 50°C.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 5 d
- at the temperature of:
- 50 °C
Additional information
The test was run over 120 hours at pH 4.588, 7.264 and 9.236. The temperature was 50 ± 1°C.
After incubation for 120 hours (5 days), dimethyl carbonate degraded less than 10% at each pH tested, indicating that the half-life at 50°C is greater than 5 days. At the environmentally relevant temperature of 20°C, it is considered that the half-life would be much greater than 5 days and possibly longer than 1 year in the pH range 4.6 to 9.2.
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.
