Description of key information

logPow=5.8 at 25°C
(calculated)

Key value for chemical safety assessment

Additional information

The preliminary experiment shows that the expected Pow lies outside the range of the flask shaking method and must be estimated by the calculation using computer program CLOGP Release 3.42.

Additionally the test substance is a complex mixture (UVCB) thus the logPow values on representative selection components have been also individually calculated and are as follows:

logPow= 2.8 of PYR-QA

logPow= 1.4 of QA

logPow= 4.2 of 2PYR-QA

logPow= -1.8 of QAMS

logPow= -0.4 of PYR-QAMS
