Additional information
Bis(2-ethylhexyl) carbonate did not cause any toxic effects up to its water solubility limit in the acute aquatic toxicity tests performed in accordance with the respective OECD guidelines covering three trophic levels. Thus, Bis(2-ethylhexyl) carbonate is considered to be non acute toxic to aquatic organisms in accordance with Regulation (EC) No 286/201, 4.1.2.6, Note 4.
QSAR modelled ecotoxicity reference values (ERV) for acute aquatic toxicity as well as for chronic aquatic toxicity, calculated with ECOSAR (v1.11), exceed the water solubility limit of the substance by factors of 37 and 3.7, respectively.

Therefore, toxic effects to aquatic organisms can safely be judged as unlikely to occur based on experimental results as well as on reliable QSAR predictions. Considering in addition the poor water solubility, ready biodegradability and high Henry's law constant of Bis(2-ethylhexyl) carbonate, availability of the substance in the aquatic ecosystem can be expected to be low. Experimental data on aquatic bioaccumulation is lacking. However, from reliable in vitro data on percutanous absorption via human skin, it can be assumed that the test substance has a low potential to cross biological membranes. Thus, a very low biological availability of the test substance can be expected for aquatic species as well.
PNECs for sediment and soil can in general be derived by the equilibrium partitioning method based on aquatic tests. As no effects could be seen up to the solubility limit in short term tests with aquatic organisms and missing aquatic toxicity is also likely in consideration of QSAR modelled acute and chronic ecotoxicity reference values, no effects are expected for terrestrial organisms.
In conclusion, based on toxicity assessment as well as on availability likelihood, a hazard to the aquatic environment is not ascertainable and consequently the derivation of PNECs is dispensable.
Conclusion on classification
The substance needs not to be classified according to Directive 67/548/EEC. It is assessed not to be a PBT or vPvB substance. According to GHS Regulation EC No 1272/2008, Bis(2-ethylhexyl)carbonate does not need to be classified as hazardous to the aquatic environment and does not need to be classified as hazardous to the ozone layer. Therefore, according to REACH Regulation, Article 14 (4a) an exposure assessment does not need to be performed.
