Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Key value determined using EU Method A8 and OECD guideline 117.

Key value for chemical safety assessment

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

Additional information

Partition coefficient (log P) of DUSANTOX 86 (4-(1-methyl-1-phenylethyl)-N-[4-(1-methyl-1-phenylethyl)phenyl]aniline is:


log P = 7.90 ± 1.22 (25°C, pH = 6.9)


It is noted that the range for the experiment is outside of the general range specified within the OECD Guideline. However this range can be expanded by the use of appropriate additional reference substances, and this is the current practice by a number of test houses. The results detailed above are presumed therefore to have been calculated utilising such expanded reference substance ranges.
