Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance was found to be hydrolytically stable with a half-life of 643 days at pH 7 and 25 °C (OECD TG 111, GLP). Furthermore, the substance was not readily biodegradable in a standard carbon dioxide evolution test (OECD TG 301 B). A GLP simulation study using aerobic natural water according to OECD TG 309 produced half-lives at 20 °C ranging from 87 to 97 days. Furthermore, a set of GLP simulation studies according to OECD TG 308 (or similar test guidelines) using natural aerobic water/sediment systems resulted in half-lives in the water phase of 19.2 days and half-lives in the sediment phase of 29.2 days at 20 °C. Finally, a set of GLP simulation studies using natural soils in accordance with OECD TG 307 (or similar test guidelines) gave a half-life of about 51 days at 20 °C. A large body of GLP studies on the adsorption coefficient in soil and sediment is available, resulting in a geometric mean value of 53.04 L/kg (n = 25) and indicating that the substance is considered as mobile in soil and sediment. The low experimental value of the octanol-water partition coefficient (log Kow = - 0.13) indicates a low potential for bioaccumulation of the substance.
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.
