Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A GLP-compliant hydrolysis study was performed according to OECD 111. In the preliminary Tier 1 study, a decrease in concentration of >10% (i.e. 98%) was observed after 5 days at 50°C at pH 4, 7 and 9, likely due to volatility. Therefore a Tier 2 study was performed. using minimum headspace in the test vessels. The test substance was stable in this test: < 10% hydrolysis after 5 days at 50°C was observed at pH 4, 7 and 9 in the Tier 2 test. This corresponds with a half-life time at 25°C of > 1 year and the substance can be considered hydrolytically stable at pH 4, 7 and 9.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 1 yr
- at the temperature of:
- 25 °C
Additional information
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.
