Calculation of logKow
log Kow = log(166613.0/650.4) = log(256.2) = 2.41
Description of key information
Partition Coefficient (LogKow) of the test item is 2.41.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 2.41
- at the temperature of:
- 22.85 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
