Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One experimental study according to OECD 301C confirmed that the test substance is not readily biodegradable according to the OECD criteria (2% biodegradation after 28 d). Considering the high water solubility (> 1000 g/L) and the low potential for adsorption to organic soil and sediment particles (log Koc: -0.4689 to 1, KOCWIN v2.00), the main compartment for environmental distribution is expected to be the surface water. The degradation via abiotic hydrolysis is not considered to be a relevant degradation pathway in the environment since an experimental study (Tosoh Corporation, 2014) resulted in DT50 values > 1 year at pH 4, 7 and 9. Since the substance is not readily biodegradable, persistence in the water phase cannot be excluded. Evaporation into air and the transport through the atmospheric compartment is not expected since the test substance is not volatile based on the low vapour pressure (< 0.95 Pa, at 20 °C). Accumulation in air and the subsequent transport to other environmental compartments is not anticipated. The potential for bioaccumulation of the test substance is assumed to be low based on the log Kow of < 0.3.
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.
