Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 registered substance is considered hydrolytically stable at environmentally relevant pH and not readily biodegradable. However, the registered substance disappears totally in the biodegradation study to form two degradation products: succinic acid (degraded and mineralized completely) and 3,3-dimethyl cyclohexanone (called DMCH, which is present at 100% after 28 days). Therefore, the registered substance is not considered persistent. DMCH also is not considered persistent in the environment according to QSAR prediction: 62% biodegradation after 60 days and predicted ultimate half life at 19 days (well below the threshold value of 40 or 60 days for P or vP criteria).
The registered substance has low mobility in soils (according to P.J. McCall et al., 1980) with a Koc value at 1386 L/kg (log Koc = 3.142) and with a log Kow value at 4.1, is considered to be potentially bioaccumulative according to CLP criteria (> 4.0) but is not considered to be bioaccumulative according to PBT criteria (< 4.5).
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.
