Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 determined Koc value of 1259 L/kg indicates that the substance will have moderate potential to adsorb to sediment/soil.
A Henry's law constant was calculated which showed a value of 3.47 Pa. m3/mol at 12 °C. This means that volatilisation will only play a minor role in the environmental behaviour of the substance.
Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 57378-68-4 and the measured physico-chemical parameters and Koc value as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (83.9%) and water (15%) with small amounts to sediment and air (1.05% and 0.05%, respectively).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plantbased on vapour pressure, water solubility, log Koc and biodegradability. The results of this show that the substance will not be degraded and that 82.3% of the substance will partition to water, 13.3% will partition to sewage sludge and 4.38% to air.
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.
