Additional information

According to REACH Regulation (Annex IX, 9.3.2, column II), test for bioaccumulation in aquatic species does not need to be conducted as the substance has a low potential for bioaccumulation.

Insolubility of the test substance and its rapid biotic degradation in water leads to negligibly low concentrations of Stearic acid, esters with methyl α-D-glucoside in the aquatic environment and thus to insignificant concentrations in aquatic organisms.

In connection with readily biodegradability of the substance, it can be concluded that Stearic acid, esters with methyl α-D-glucoside is supposed to be not biologically available in the aquatic compartment and it can be assumed that bioaccumulation in aquatic species is negligible.

In addition, readily biodegradable chemicals generally have a higher probability of being metabolised. In a case of ester fission the Stearic acid, esters with methyl α-D-glucoside, consisting of α-methyl glucose and fatty acid chains, is likely to be rapidly metabolised in organisms.
