Additional information

Due to the calculated log Pow of 1.543 for the test substance 'diallyl 2,2'oxydiethyl dicarbonate' (EC 205 -528 -7), which is a near analogue of 'Reaction mass of 2,2'-oxydiethanol and 2,2-dimethylpropane-1,3-diol and diallyl 2,2'-oxydiethyl dicarbonate and diallyl carbonate and pentaerythritol' (EC 700 -742 -1), accumulation in organisms is not expected. Trigger value for undertaking an experimental aquatic bioaccumulation test is a logPow value of 4.5 or higher. Hence, no further studies regarding bioaccumulation in organisms are performed.

The bioconcentration factor (BCF) of Diallyl-2,2'-oxydiethyl dicarbonate (EC 205 -528 -7) was determined by the computer program BCFBAF v3.01 (EPIWIN software) by US-EPA for completeness (Chemservice S.A., 2010). Using the regression-based estimate (traditional method) of the computer program BCFBAF from US-EPA a Bioconcentration Factor (BCF) of 4.843 L/kg wet-wt was calculated for the test substance, confirming that bioaccumulation in aquatic biota is unlikely.
