Remark:
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
fact that the test item is a mixture. 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:
2.3 mg/L ± 0.6 mg/L for tests with 1.0 g/L
5.2 mg/L ± 0.4 mg/L for tests with 10.0 g/L
Applicant's summary and conclusion
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.
