Description of key information
logPow= <3.7 at 20°C
Key value for chemical safety assessment
Additional information
The logPow was determined using HPLC method.
The test substance is a mixture of approximately 6 major components and several traces. Therefore the partition coefficients (n-octanol/water) for the components detectable with the chromatographic system used, were determined to be logPow= <0.....3.7 at 20°C
It can be concluded that the partition coefficient was determined to be logPow= <3.7 at 20°C
