Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the key biodegradation studies, the registered substance is considered readily biodegradable (Wildlife International, 2000) and is considered almost totally removed from a WasteWater Treatment Plants (WWTP) (99.9% of removal; Weston, 1995). As the substance is readily biodegradable, no further assessment of the stability of this compound is necessary (e.g. hydrolysis study).
The adsorption coefficient (Koc) of the registered substance was estimated with three calculation methodologies using the experimental log Kow value of 5.52: MCI method from KocWin v2.00 (EPI Suite v4.1), log Kow method from KocWin v2.00 (EPI Suite v4.1) and TGD equation. The retained value is a geometric mean of these results, corresponding to a log Koc at 4.18 (Koc = 15094 L/kg). This result indicates that the substance is immobile in soil (according to P.J. McCall et al., 1980).
Considering the sensitivity analysis of log Koc on PEC and RCR, the expected likely variation interval of an experimental log Koc determination and that the risk would remain acceptable, it is not deemed relevant to perform any experimental study (see attached report for details).
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.
