Applicant's summary and conclusion

Conclusions:
The water solubility of the test item was determined according to OECD guideline no.105 [adopted on 27 July 1995] and EU test method A.6 [Directive 92/69/EEC, Official Journal L 383 [1992] with the column elution method.
Water solubility (at 20 °C): 37 µg/L
