Description of key information

The log Pow of the test item is < -5 at 23 °C (estimated from the single solubilities in n-octanol and in water).

Key value for chemical safety assessment

Additional information

Because of the different solubility of the test item in water and in n-octanol and the fact that the test item is probably not a pure substance, the determination of the log Pow corresponding to the OECD Guideline for the Testing of Chemicals 107 (shake flask method) is not feasible. Because the test item cannot be chromatographed under the prescribed conditions the HPLC-method (OECD Guideline for the Testing of Chemicals 117) is also not feasible. Due to this, the log P ow can only be estimated from the single solubilities of the test item in water and in n-octanol.

The GLP study resulted a log Pow of the test item of < -5 at 23 °C and pH 5.8.
