Results and discussion

Applicant's summary and conclusion

Conclusions:
The water solubility of the test substance is 5.85 µg/l (see section 4.8). According to the guidelines, substances with a water solubility < 1 mg/l need not be tested. The test on the surface tension of the test substance was therefore not performed.
