Results and discussion

Applicant's summary and conclusion

Executive summary:

Statement

According to the guideline, the concentration of test samples should not exceed half the water solubility of the test substance or 0.01 M, whichever is lower. The water solubility of the test substance is <3.75 µg/l. No analytical method was available to support the hydrolysis test at this low concentration level. The test on the hydrolysis of the test substance could therefore not be performed.
