Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The hydrolysis half-live at pH = 7 of the test substance was considered to be < 2 minutes.
The test item can be considered to be not ready biodegradable but inherently biodegradable.
Additional information
Hydrolysis
The hydrolysis rate of the test substance at pH = 4, 6, 7 and 9 (at room temperature) was investigated using FIMS (Flow Injection Mass Spectrometry). Short- and long-term measurements show that the test substance hydrolyzed faster at pH 4, 6 and 7 than at pH 9. FIMS data showed that at pH = 7 after 2 minutes only a weak signal of the test substance could be detected. Thus the hydrolysis half-live at pH = 7 was considered to be < 2 minutes.
Biodegradation
The ready biodegradability of the test item was assessed over a 28 day period in a closed bottle test (OECD No. 301 D, 1992 and EU method C 4-E) . The percentage biodegradation of the test substance reached a mean of 24.8 % after 28 days based on its ThODNH4. Therefore the test item can be considered to be not ready biodegradable but inherently biodegradable.
The reference item sodium benzoate was sufficiently degraded to a mean of 67.6 % after 14 days, and to a mean of 71.9 % after 28 days of incubation.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.
