Description of key information

The Log Kow of Dioctyltin mercaptopropionate was calculated to be 4.1185.

For the risk assessment, a temperature of 25˚C was assumed.

Key value for chemical safety assessment

Log Kow (Log Pow):
4.119
at the temperature of:
25 °C

Additional information

The partition coefficient of Dioctyltin mercaptopropionate was calculated using KOWWIN v1.68. Given that the substance is an organic molecule within the molecular weight range of the training set compounds, the prediction is considered to be acceptable.

The Log Kow of the test material was calculated to be 4.1185.
