Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Available data on Hydrolysis and Biodegradation suggest that the substance is unlikely to break down rapidly in the environment. A Ready Biodegradability Study (Kurume Laboratory, 2001) indicated minimal degradation (2%, measured in terms of biochemical oxygen demand) over the 28-day study period, and a measurement of Hydrolysis as a Function of pH (Huntingdon Life Sciences, 2003) estimated the hydrolysis half-life of the substance at 25°C to be greater than 1 year at each of the pHs tested (4,7, and 9).
Although the substance is not likely to undergo significant biotic or abiotic breakdown in the environment, it is likely to have a high mobility. A Soil Adsorption Study (Huntingdon Life Sciences, 2003) performed by HPLC calculated a soil adsorption coefficient, Koc of 118.04 (log Koc= 2.07). On this basis, the substance would not be expected to adsorb onto sediment.
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.
