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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Abiotic degradation:
The constituents of the substance do not contain hydrolysable functional groups. Therefore, no abiotic degradation like hydrolysis is expected.
Biodegradation:
One experimental study according to OECD 301 D (closed bottle test) indicated that the substance is inherently biodegradable.
Transport and distribution:
The adsorption potential to soil and sewage sludge was assessed in a OECD 121 study, via an HPLC method. For soil the log Koc values were in the range of 1.95 to 5.75, with as key value: log Koc (soil) = 3.01 (main peak, 52.8 % area). For sewage sludge, the log Koc values ranged from 1.83 to 6.22, with as key value: log Koc (sewage sludge) = 3.05 (main peak, 52.8% area). This corresponds to Koc, soil = 1023.3 L/kg and Koc, sewage sludge = 1122 L/kg. Clearly the substance has a preference for adsorption to soil and/or sewage sludge (Mobility class according to McCall et al. (1981): Low).
Henry's law constant has been calculated and is 5058.2Pa * m3/ mol at 20°C, indicating that the substance has the potential to evaporate rapidly from the water phase into the atmosphere.
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.
