Applicant's summary and conclusion

Conclusions:
The water solubility of the test item has been determined to be less than 1 x 10E-3 gTOC/L of solution at 20.0 ± 0.5 °C.
Executive summary:

The determination was carried out by the flask method, using a procedure 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.

Conclusion

The water solubility of the test item has been determined to be less than 1 x 10-3 gTOC/L of solution at 20.0 ± 0.5 °C.
