logKoc: > 5 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No experimental studies investigating the adsorption/desorption potential of Propyleneglycol dioleate (CAS 105-62-4) are available. Therefore, the Koc was calculated using KOCWIN v2.00 based on the Molecular Connectivity Index (MCI) (Werth, 2014). The QSAR calculation resulted in a logKoc value of 9.0. The used QSAR model has no universally accepted definition of model domain, but since the substance is outside the Kow range of the training set of the MCI model, the results should be taken with caution. The definite values may not be fully reliable, but indicate a high adsorption potential, which is also to be expected based on the high Kow (> 10) and low water solubility.
