Description of key information
According to the reference, the adsorption/desorption coefficient (logKoc) of SymMollient S is calculated as follows:
Hexadecyl nonanoate: 6.2 (MCI method)
Hexadecyl nonanoate: 7.0 (logPow method)
Octadecyl nonanoate: 6.8 (MCI method)
Octadecyl nonanoate: 7.6 (logPow method)
Key value for chemical safety assessment
Additional information
An adsorption/desorption screening study was not initiated since the substance is readily biodegradable and thus decompose rapidly. The logPow is calculated according to QSAR (EPI Suite- KOWWIN v1.67) to be in thr range of 11.2 for hexadecyl nonanoate and 12.2 octadecyl nonanoate.
Nevertheless, the adsorption/desorption coefficient for SymMollient® S was calculated with QSAR (EpiSuite - KOCWIN v2.00). Two methods were used (i) MCI method and (ii) logPow method. Result: logKoc: 6.2 and for hexadecyl nonanoate and 6.8 and 7.6 for octadecyl nonanoate, respectively.
