Description of key information

CDI (bis(2,6-diisopropylphenyl)carbodiimide): 
1) Pow > 1.58E6; logPow > 6.20 [exp. result, GLP-study, 2001]
2) logPow = 8.72 (at 25 °C) [KOWWIN 1.68; calculated data].
DIPA (hydrolysis product):
logPow = 3.99 (at 25 °C) [KOWWIN 1.68; calculated data].

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
30 °C

Additional information

The key value was determined by the HPLC method (EU method A.8) in accordance with GLP requirements (White and Mulley, 2001). As supporting information a calculation was performed with US-EPA software EPIWIN/KOWWIN (v1.68), resulting in a logPow value of 8.72.

Additionally, the logPow was estimated for the relevant hydrolytical degradation product 2,6 -diisopropylaniline (DIPA; CAS No. 24544 -04 -5).

The calculation with EPIWIN/KOWWIN (v1.68), resulted in a logPow value of 3.99.
