Description of key information

log Pow  = 5.82 - >10

Key value for chemical safety assessment

Additional information

The log Pow of the substance hexanoic acid, 2-ethyl-, C16-18 alkyl esters (CAS 90411-68-0) was determined according to OECD Guideline 123 (Partition Coefficient (1-Octanol / Water), Slow-Stirring Method) (log Pow = 5.28). The QSAR calculations for the single components resulted in higher log Pow > 10.

The determination according to the slow stirring method is appropriate for log Pow ≤ 8. As the components of the substance are long chain fatty acid esters (C16 -18), the calculated values are taken into consideratio in a weight of evidence approach.
