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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is NOT considered as a volatile organic compound (V.O.C.) according to Directive 1999/13/EC criteria.
Key value for chemical safety assessment
- Vapour pressure:
- 0.017 Pa
- at the temperature of:
- 20 °C
Additional information
An experimental study is available on the substance, but reliability could not be assigned, due to lack of information. Therefore, two QSAR models were used in a weight of evidence approach. The raw VP estimations were found to be consistent with each other, however their predictions for BP were found to be significantly higher than the available experimental value. As VP and BP are closely related, the first set of VP was supposed to be underestimated. For the model that could be refined, correction with experimental MP and BP lead to an estimated VP very close to the experimental result. This supports the reliability of the study.
The experimental value is prefered (to the mean of exp. and qsar) and retained as key value for purpose of CSA.
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.
