2 data are available at standard temperature (EPI SuiteTM software program):- log Kow = 2.54 (calculation model KOWWIN v1.76)- log Kow = 2.42 (experimental data base - Sangster)
No full report of
experimental study is available for the partition coefficient of
As the applicability of the EPIWIN program (KowWin
v1.67) for the estimation of logKow values of heptanoic acid has been
demonstrated by the QPRF, this calculated value is considered acceptable
and its reliability is considered as "2".
The estimated logKow
values is consitent with the experimental data reported in the
experimental data base of the model (Sangster).
Thus, the value of
partition coefficient selected for the risk asssement is the higher
value => log Pow =2,54.
This value indicates a low potential for heptanoic
acid to accumulate from water into organisms.
