Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Based on the physicochemical properties, the substance is expected to possess a low potential for adsorption: it is characterized by a negative octanol water partition coefficient, due to the high capability to dissolve in water phase.
The log Koc and the partition coefficients necessary for the PNECs calculation (PNEC sediment freshwater, PNEC sediment marine and PNEC soil) were estimated using the EUSES 2.1.2 tool*.
The log Koc has also estimated using the KOCWIN v.2.00**, for completeness sake; the results confirm the expectation of a low potential for adsorption.
KOCWIN v.2.00
Soil Adsorption Coefficient Koc has been estimated as 0.6687 l/kg (log Koc: -0.175), based on the kow method. The estimation has been performed entering the experimental determined water solubility (400 g/l) logPow (-1.98) values.
EUSES v.2.1
The organic carbon-water partition coefficient has been estimated 0.978 l/kg (log Koc: -0.01).

**KOCWIN v.2.00 is an application contained in the EpiSuite 4.1, the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
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).
