Description of key information

Based on QSAR calculations with Catalogic vs. 5.11.16 the log KOW for the registered substance is evaluated.

Each individual C chain of the UVCB substance is modelled.

The log KOW was derived by summation of the individual modelled log KOW values for each alkyl chain related to their amount within the UVCB.

The obtained log KOW is 3.82

Key value for chemical safety assessment

Log Kow (Log Pow):
3.82
at the temperature of:
20 °C

Additional information

A measured Log KOW value of 1.8 according to OECD 105 is available for the target substance. However, taking into account the discussion from the HERA report, the value is considered to be not sufficiently reliable and is therefore only regarded as supporting study. In an additional approach, the log KOW was derived by summation of the individual modelled log KOW values for each alkyl chain related to their amount within the UVCB. The obtained log KOW is 3.82 and is considered as more reliable
