Description of key information

The log Kow for the test item was estimated to be 8.34.

Key value for chemical safety assessment

Log Kow (Log Pow):
8.34

Additional information

As the test item bis(4-tert-butylcyclohexyl) peroxydicarbonate is a substance difficult to test the log Kow was estimated using EPISuite (US EPA, 2012), and corresponding QMRF and QPRF documents were prepared. The predicted value is log Kow = 8.34.

Approach for regulatory interpretation of the model result: The regulatory cut-off value for the log Kow ranges between 3 (potential for bioaccumulation and adsorption) and 4 (classification and labelling).

Outcome: The estimated log Kow for the substance is relatively high and indicates the substance's potential for adsorption and bioaccumulation.

Conclusion: The final result is considered adequate for a regulatory conclusion. No additional information is required.
