Description of key information

The partition coefficient log Pow of each isomer included in the mixture m/p diol is 1.6.

Key value for chemical safety assessment

Log Kow (Log Pow):

Additional information

The partition coefficient (log Pow) of a mixture is not a relevant data that's why no test was performed. However, data are available on each isomer which was tested separately according to the OECD 117 guideline. The data obtained show that both isomers have the same value of Log Kow = 1.6.


These results, in addition to those available for the water solubility, allow us to consider that both isomers should have the same behaviour in environment. As a consequence, a data obtained with an isomer should be considered as valid for the other isomer, as well as for the mixture of both substances.
