Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
This substance's water solubility is << 0.5 mg/L at 20 °C.
Key value for chemical safety assessment
- Water solubility:
- 0.5 mg/L
- at the temperature of:
- 20 °C
Additional information
The substance is considered insoluble in water (<< 1 mg/L). A critical reviewer finds flaws in the method used to generate the experimental data suggesting that the water solubility of this substance is 0.5 mg/L. The method used was inappropriate for the measurement, and more likely reflects mechanical disruption of material adsorption onto the glass wall of the vessel. The reviewer believes that the water solubility of the substance is about 3 orders of magnitude lower than the reported value. In support of this finding, QSAR modeling (EPISuite, v.4.00) predicts a value of 0.00024 mg/L (0.24 microgram/L).
For CSA purposes, a maximum value of 0.5 mg/L was used.
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.
