Applicant's summary and conclusion
- Conclusions:
- The water solubility of the test item has been determined to be less than 1.64E-02 g/L at 20.0 ± 0.5 °C based on selected components. It was considered that the water solubility of the test item as a whole would be less than 1E-03 g/L.
- Executive summary:
The water solubility of the test substance was less than 1.64E-02 g/L of solution at 20.0 ± 0.5 °C, using the flask method, designed to be compatible with Method A.6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. It was considered that the water solubility of the test item as a whole would be less than 1E-03 g/L.
