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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ADSORPTION / DESORPTION
The registration substance has a measured Log Kow of 3.3 and based on this value the Exposure Modelling Program EUSES 2.1 calculates a Koc of 544 L/kg ; logKoc=2.73 (QSAR for non-hydrophobics) corresponding to a Kd soil of 10.9 L/kg, Kd sediment of 27.2 L/kg and Kd activated sludlge of 201 L/kg. These Kd values are low which means that an Adsorption / Desorption study is not warranted.
AIR - WATER PARTITIONING
Based on the measured water solubility of the registration substance of 25 mg/L at 20 deg C (see IUCLID Chapter 4.8) and a calculated vapour pressure of <0.001 Pa at 25 deg C the Exposure modelling program EUSES 2.1 calculates a Henry's Law Constant of 1.14 E-02 Pa*m3/mol at 12 deg C and a dimensionless Air-water partitioning coefficient of 4.79 E-06 m3/m3 at 12 deg C.
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.
