According to REACH Annex IX and X, column 2, testing of toxicity
to soil organisms depends on the outcome of the chemical safety
assessment. As no data on soil organisms are available, a screening
assessment was performed. For this purpose the reaction mass was
assigned a soil hazard category: 1) EC/LC50-values for daphnia, algae
and fish for reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and
2-methylpropan-2-ol (TBA) are > 1mg/L; 2) The reaction mass is not
readily biodegradable, but not highly persistent as volatilization and
leaching will lead to removal of the components from the soil
compartment. Therefore, it is classified in soil hazard category 1
((ECHA TGD IR & CSA, 2008, R7c, p.131). The PNEC for soil organisms was
estimated using the equilibrium partitioning method (ECHA TGD IR & CSA,
2008, R10, p.39). The result of this assessment indicated no risk to
soil (RCR < 1). Therefore, no further tests on soil organisms are
