Applicant's summary and conclusion
- Conclusions:
- The partition coefficient of the test material has been determined to be <2.61 x 10-3 at 23.0 ± 0.5°C, log10 Pow < -2.58.
- Executive summary:
The determination was carried out using the shake-flask method, Method A8 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC) and Method 107 of the OECD Guidelines for Testing of Chemicals, 27 July1995.
The partition coefficient of the test material has been determined to be <2.61 x 10-3at 23.0 ± 0.5°C, log10Pow < -2.58.
