Additional information

The water solubility of SymMollient S is 3.5 µg/L for hexadecyl nonanoate and 1.7 µg/L for octadecyl nonanoate. According to Annex VII section 7.8 Column 2 of regulation 1907/2006 this study does not need to be conducted for poorly soluble substances.

However, according to QSAR (EpiSuite 4.0), the partition coefficient n-octanol/water (log Pow) of SymMollient S is calculated as follows:

Hexadecyl nonanoate: 11.18

Octadecyl nonanoate: 12.16
