Description of key information

The Partition Coefficient range for this Category was >2.4 and <6.5. Data are available for three of the streams in this category. The data will be read across to all category members.

The mean of the partition coefficient values for the category gives a log Kow of 4.26 at a mean temperature of 24°C and this value has been used to complete the 'key value for chemical safety assessment'.
