Description of key information

The solubilities at 20°C and at pH 5.6 were found as follows:

1.6 mg/l with a loading rate of ca. 1 g/L

2.3 mg/l with a loading rate of ca. 10 g/L

Additionally, the estimated values of the individual constituents are as follows:

Group A= 0.014 mg/L

Group B= 1.544E-4 mg/L

Group C= 1.939E-6 mg/L

Group D= 1.167 mg/L

Key value for chemical safety assessment

Additional information

The test item is a mixture of compounds. Every constituent contributes to a different degree to overall solubility, depending on its own individual solubility and its mass fraction in the test item. Thus, analytical results depend on the proportions of test item and water used in the experiment.

The determinations were carried out by flask method in accordance with the OECD Guideline 105. Although the water solubility is <10 mg/L, the flask method was carried out because tests according to the column elution method had shown that the different constituents have different solubilities in water. The quantification was analyzed by TOC.

In addition, the solubilities of the individual constituents have been generated using recommended WSKOW (v1.42) module of software EPI Suite v.4.11.
