Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is abiotically stable under environmentally relevant conditions: At pH 7 its DT-50 is > 1 year.
The substance was tested for ready biodegradability, inherent biodegradability and enhanced ready biodegradability under OECD 301 and OECD 302 test designs. Based on the results of the tests performed, the substance can not be considered as readily biodegradable or inherently biodegradable. However, in the key studies for ready and inherent biodegradability, the substance exhibited a significant amount of mineralization within 28 days, i.e., up to average 45% (OECD 301 B) and 58% (OECD 302 B), respectively. Besides, at the end of the incubation period of OECD 301 studies (day 28), the plateau phases were not reached. Results of enhanced biodegradation studies show repeatedly, that more than 60% of the substance was ultimately degraded within 60 days of incubation under OECD 301 test design. Hence, though the substance is not readily biodegradable, it is not considered persistent in the environment.
The log Koc value (3.844) of the substance indicates that the substance is slightly mobile according to FAO mobility classification, i.e., that it does adsorb rather strongly to soil or sediment.
The BCF of 70.8 L/kg indicates that the substance is not bioaccumulative and hence bioaccumulation is of no concern.
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.
