Description of key information

The logKow of the substance (XDI) at 25 degrees Celsius is calculated to be 3.07 and the logKow of the hydrolysis product (XDA) is calculated to be 0.15 at 25 degrees Celsius.

Key value for chemical safety assessment

Additional information

It is technically not feasible to conduct the study as the substance (XDI) reacts with water. In accordance with the ECHA Guidance on information requirements and chemical safety assessment (Chapter R.7a: Endpoint specific guidance), the log Kow of the substance has been calculated with the KOWWIN program (version 1.67), with the ACD PhysChem program (version 12.01) and with the ACD ADME Suite program (version 5.07). The average of the 3 predictions (3.07) should be used. The partition coefficient of the hydrolysis product (XDA) is calculated with KOWWIN (version 1.67), part of EPI Suite.
