Description of key information

The solubilities at 20°C were found as follows:

0.031 g/L at pH 7.5 with a loading rate of 1 g/L
0.146 g/L at pH 7.4 with a loading rate of 10 g/L

Key value for chemical safety assessment

Additional information

The determination was carried out by flask method according to OECD Guideline 105 and analysed using TOC method.

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.
