An experimental study to the read across substance Isostearic acid, esters with methyl α-D-glucoside is available. Based on the structural analogue approach to Stearic acid, esters with methyl α-D-glucoside, read across from Isostearic acid, esters with methyl α-D-glucoside, is considered acceptable.

 

The log Koc of the major component of Isostearic acid, esters with methyl α-D-glucoside was determined to be >5.63 (Koc>427000). The value is supported by calculation performed for the main components of Stearic acid, esters with methyl α-D-glucoside. The calculation yielded a Koc=5986 L/kg (log Koc=3.777); Koc=3.047x10E+7 L/kg (log Koc=7.484);  Koc=3.757x10E+12 L/kg (log Koc=12.575) and Koc=2.611x10E+17 L/kg (log Koc=17.417) (Kow method) for mono-, di-, tri- and tetraester respectively.

Based on these results and taking into account the classification of Blume & Ahlsdorf (1993), a high to very high sorption of Stearic acid, esters with methyl α-D-glucoside onto soil organic matter is to be expected.
