Results and discussion
Applicant's summary and conclusion
- Conclusions:
- 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 < 0.983 mg/l (see 4.8). 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
