Description of key information

Measured log Pow= 5.5 at 25°C.

Additionally, the individual components were calculated as follows:

Log Pow of Structure A, main component= 5.6 - 5.8

Log Pow of Structure B= 5.8

Key value for chemical safety assessment

Log Kow (Log Pow):
5.5
at the temperature of:
25 °C

Additional information

The determination was carried out by HPLC method according to the EU test method L383 A/63-73 (EU A.8).

Triphenylamine exhibits the second highest log Pow value listed in the EU test procedure (5.7). DDT exhibits the highest log Pow value (6.2), but was not used due to toxicological reasons.

In addition, the log Pow values of the individual constituent have been generated using KOWWIN (v1.68) module of software EPI Suite v.4.11. The molecular weight of both structures are within range of training and validation set.
