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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test item will remain mainly in the water phase, no adsorption to the solid soil phase or volatilization into the atmosphere is expected.
Additional information
Based on the low log Kow of 0.35 (experimental, Hantsch et al. 1995) the log Koc was calculated by QSAR and according thethe formular given in ECHAs TGD part 3. The log Koc was < 3 (1.202, BASF, 2008) therefore no adsorption to the solid soil phase is expected. The experimental value for the Henry’s law constant (HLC) of 0.034 Pa·m3 mol-1 at 25 °C (Betterton, 1988) indicates that volatilization from an aquatic environment into the atmosphere is unlikely under environmental conditions.
Both parameters indicate a distribution of the test item towards the water phase. This was confirmed by distribution modelling according to Mackay Level I calculations. Based to these calculations the test item will remain mainly in the water phase when released to the environment (98.8 %).
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.
