Description of key information

The weighted mean log  Pow of the substance was 2.32.

Key value for chemical safety assessment

Log Kow (Log Pow):
2.32
at the temperature of:
23.5 °C

Additional information

The partition coefficients for the three major components of the test item have been determined:

The partition coefficient of the Mannich base species in the tested substance is 596,. The Log(10) Pow is 2.78 at 23.5+/-1.0°C

The log Pow of the p-tert-Butylphenol component was >= 2.52 — <= 3.28, the log Pow of the m-Xylylenediamine component was 0.00694. For chemical safety assessment, a weighted mean has been calculated resulting in a log Pow of 2.32.
