Key value for chemical safety assessment

Additional information

In the present study, the partition coefficient of test item was estimated by a model calculation based theoretical fragmentation of the molecule into suitable substructures for which reliable Log Pow increments are known. The Log Pow was obtained by summing the fragment values and the correction terms. As the number of the tertiary butyl group at the triphenylphosphit is not well-defined, the partition coefficient was calculated for n = 0, n = 1 and n = 2 tertiary butyl groups.

logPow= 4.3 (n=0)

logPow= 6.2 (n=1)

logPow= 8.1 (n=2)
