Description of key information

-0.35 key value 20degrees
Based on the primary information sourced from a TGD-approved handbook, the substance has a log Pow of 0.05 at 25°C.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

There are no data available for the reaction mass. The log Kow value can be determined by the values of the two constituents and is concluded to be between -0.35 and 0.05. For chemical safety assessment purposes the highest value will be taken.


A number of very similar values are available from different sources that are believed to originate from measured data. These values are almost identical. The value is based on the measured value from the key study. Whilst this was determined at 24C, the value is not expected to be sensitive to temperature or pH within normal environmental ranges.
