Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance is hydrolitically stable under environmental conditions (pH7).
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 250 h
- at the temperature of:
- 39 °C
Additional information
In a GLP-compliant study according to EC guideline No L 251/C.10, hydrolysis of the test substance was tested at varying temperatures and as a function of pH (CG, 1985).
In a preliminary test at 50 °C, it was determined that hydrolysis of the test substance is <10 % at pH 4.0 and 7.0 and >10 % at pH 9.0. Calculated half-life times at pH 4 and 7 and at 25 °C were >1 year. Hence in the final test the hydrolysis was examined only at pH 9.0 and a temperature of 39 °C. The half-life time under these conditions was 250 hours.
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.
