Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
At 20°C, the following solubilities were found:
32 mg/L ± 2 mg/L for tests with 1.0 g/L
158 mg/L ± 7 mg/L for tests with 10 g/L
Key value for chemical safety assessment
- Water solubility:
- 32 mg/L
- at the temperature of:
- 20 °C
Additional information
A study according OECD TG 105 was conducted to evaluate the solubility of the test item in water at 20 ± 0.5 °C. A preliminary test was carried out where the solubility of the test item was determined to be below 12 mg/L. The shake-flask method was used for the main test and the water solubility was determined via TOC. The solubility in water is not a constant, but increases with the mass of test item applied in the experiment. This is due to the test item being a mixture of homologues rather than a single compound. Every constituent contributes to a different degree to overall solubility, depending on its own individual solubility and its mass fraction in the test item. Therefore, results depend on the proportions of test item and water used in the respective experiment.
At 20.0 °C ± 0.5 °C, the following solubilities were found:
32 mg/L ± 2 mg/L for tests with 1.0 g/L
158 mg/L ± 7 mg/L for tests with 10 g/L
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).
