Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test item is a honey coloured clear viscous liquid having no melting point above – 20 °C and which boils under decomposition at 240 °C. The substance has a low vapour pressure of approximately 0.006 Pa at 25 °C and the flash point is approximately 202 °C at atmospheric conditions. Auto-ignition occurs at 420 °C (decomposition products) and the relative density at 20 °C is approximately 1. The substance’s partition coefficient octanol / water (log Pow) and water solubility could not be determined experimentally due to surface active properties (surface tension: 28.5 mN/m) and therefore QSAR estimation is used. The estimated log Pow is 3.98 (KOWWIN v1.68) and results in an estimated water solubility of 0.59 mg/L (WSKOWWIN v1.42) at 20 °C.
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.
