Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
An experimentally determined average log Koc value of 3.83 (corresponding to a Koc of 6760 L/kg) indicates that the substance has some potential to adsorb to sediment/soil.
To assess the volatilisation potential of the substance a Henry's law constant was calculated which showed a value of 3 Pa. m3/mol (at 12 °C). Therefore, no or limited volatilisation from water can be expected.
Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the Smiles notation: CC2(C)C(C)C(C)(C)C=1C3OCOCC3CCC=12 and the measured physico-chemical parameters as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (83.1%) and water (15.8%) with small amounts to sediment and air (< 1%). The ready biodegradability could not be considered here.
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations show that 56.7% of the substance will be degraded and the remaining part will mainly partition into sludge 33.8% with minor parts going to water 8.78% and air (< 1%).
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.
