Applicant's summary and conclusion
- Conclusions:
- The water solubility of the test item has been determined to be less than 1.07 x 10^-5 g/L of solution at 20.0 ± 0.5 °C.
- Executive summary:
The water solubility was less than 1.07 x 10^-5 g/L 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.
