Description of key information

The log Pow  of dicumyl peroxide is 5.6 at 25 °C based on the HPLC method.  

Key value for chemical safety assessment

Log Kow (Log Pow):
5.6
at the temperature of:
25 °C

Additional information

The experimental test was performed in accordance with EU method A.8, partition coefficient (n-octanol/water) and OECD guideline 117, partition coefficient (n-octanol/water), HPLC method.

Two secondary sources reported a log Pow of 5.5, which is in good agreement with the current result.
