Applicant's summary and conclusion

Conclusions:
Preliminary test, in accordance with OECD Method 105 (visual assessment), showed that the water solubility of the test substance is below the detection limit of the analytical method (0.2mg/L). Consequently, the substance appears to be insoluble in water. In reference to Annex VII of REACH, if the substance appears to be insoluble in water, then the “limit test up to the detection limit of the analytical method shall be performed”. Based upon this information, the water solubility of the test substance shall be reported at <0.2mg/L. The water solubility was determined at 20°C. The pH value of the collected aqueous fraction was 6.6.
