Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 UVCB test material has a low vapour pressure (2.8 x 10E-02 Pa at 25 °C), is poorly soluble (7.55 x 10E-02 g/L at 20.0 ± 0.5 °C) and the behaviour of the most abundant component has been modelled to provide an indication of the behaviour of the test item as a whole. The calculated Henry's Law Constant of 0.0000144 Pa.m3/moL Pa.m3/moL for 2-dodec-1-en-1-ylsuccinic acid indicates that this constituent is unlikely to partition to air. The Level III Fugacity Model confirms that volatilisation to air is of no concern for the major component of the UVCB substance and that approximately 79 % of that constituent will partition to soil. The determined Log Koc values for the UVCB itself are pH dependent with a lower percentage of highly retained components in neutral conditions and correspondingly a higher percentage of slightly retained components. This behaviour is confirmed by the predicted Log Koc for the most abundant component of the UVCB, which is predicted to lie between 2.84 and 3.97.
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.
