Description of key information

The octanol-water partition coefficient of Alcohols, C9-11 (odd numbered), branched and linear is 3.57-4.76 at 25°C

Key value for chemical safety assessment

Additional information

log Kow values in the range 3.57 - 4.76 at 25°C were determined for the constituents of the Alcohols, C9 -11 (odd numbered), branched and linear. A weighted log partition coefficient of 4.3 was reported for the whole substance by the study author.

This measurement is supported by octanol-water partition coefficients of constituents of Alcohols, C9-11 (odd numbered), branched and linear in the range 3.8-4.7, based on the known properties of the constituents.

Partition coefficient for a multi-constituent or UVCB substance is not meaningful scientifically for the purpose of assessment of exposure or risk. Exposure and risk are assessed on the basis of the individual constituents, as discussed in the CSR.
