Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The substance showed no biodegradation in two ready biodegradability tests (OECD 301B & C) over 28 days (< 5% degradation). No further biodegradation tests were conducted, as based on these results it is assumed that the substance will not be biodegraded to a relevant extent in the environment and is persistent in the environment.
Due to the high log Kow and the resulting high log Koc value of 4.165 (QSPR estimations) the substance is immobile in soil and sediment according to the classification scheme of McCall et al. (1981).
A valid and reliable bioconcentration study in fish (according to OECD TG 305) which was conducted under flow through conditions, showed that the bioconcentration factor for the substance ranged from 530 to 560 (normalised to 5% lipid content 690 to 729, respectively) in common carp. Therefore, the substance is considered to be not bioaccumulative.
A hydrolysis study according to OECD 111 revealed a half life time of 259 h at 25°C and pH 7. But as no qualitative or quantitative determination of the hydrolysis products was done, it was not possible to prove that the dissipation of the substance is due to hydrolysis and not adsorption or volatility or other dissipation processes.
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.
