Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test item is a complex UVCB with a low vapour pressure (0.323 Pa at 25 °C) and is poorly soluble (approximately 8 mg/L at 20 ± 0.5 °C). However, the UVCB is known to be readily biodegradable, and it was considered appropriate to model transport and distribution using bis(2-ethylhexyl) phosphonate [EC 222-904-6; CAS 3658-48-8] as a representative component.
The calculated Henry's Constant of 17.6 Pa.m3/moL indicates that the representative component has a tendency to partition to air whilst the estimated Log Koc of 4.13 for the component shows that, like the UVCB itself, the constituent will absorb to organic material and therefore be less mobile in soil. The Level III Fugacity Model confirms that volatilisation to air will be the weaker effect and that approximately 74 % of the representative component will partition to soil.
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.
