Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Koc value (3.844) of the substance indicates, that the substance is slighlty mobile, i.e. that it does adsorbs rather strong to soils or sediments according to FAO mobility classification.
In a distribution study, the removal of the substance during sewage treatment was estimated using the STPWIN™ module of EPI Suite™ v.4.11. STPWIN™ uses several outputs from EPI Suite™. This program predicts the removal of a chemical in a typical activated sludge-based sewage treatment plant. The program assumes a standard system design and set of default operating conditions. The results show that 90.96% of the substance was removed during wastewater treatment by adsorption to sludge. I.e. less than 10% will enter surface waters via STP effluents.
Hence, significant contamination of environmental compartments like surface waters, sediment, soil and groundwater via horizontal and vertical transport is not expected.
The very low vapour pressure of the substance indicates that the risk of environmental contamination via the air is very low.
Hence, the issue of transport and distribution in all compartments of the environment is of no concern.
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.
