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 for chemical safety assessment

Log Kow (Log Pow):
6.94

Additional information

The partition coefficient log Pow of the registered substance was determined according to test procedure VTA34N00004.01 , which complies with EU test method L383 A/63 -73 (EU A.8) .

Results : log Pow > 5.7

Calculation of Log Pow shows us value of 6.94.

Since the result of OECD 117 testing only shows us a value > 5.7 (as the test institute abstains from using DDT as a refernece substance becaus of its toxicity). Additional testing with further HPLC-runs with Ethyl benzoate, Ethyl benzene, Butyl benzene, Dibenzyl and Triphenylamine showed retention times of the test substance four times as long as Triphenylamine, which resulted in a log Pow of 23,5 using extrapolation.

Since this value is outside the applicability domain of the test calculation with a QSAR tool was done. Since the used tool is well established this value is assumed to be correct.
