Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
According to REACH Regulation (Annex IX, 9.3.2, column II), testing for bioaccumulation in aquatic species doesn't need to be conducted as the substance under investigation has a low potential to cross biological membranes and direct and indirect exposure of the aquatic compartment is unlikely.
Key value for chemical safety assessment
Additional information
No study for aquatic bioaccumulation with Bis(2-ethylhexyl) carbonate is available.
In a study conducted according to OECD Guideline 428, the penetration profile of the test substance Bis(2-ethylhexyl) carbonate (99.9 % a.i.) in human abdominal skin was analysed using an flow-through diffusion cell. The results of the in-study validation data show that the used method is able to quantify Bis(2-ethylhexyl) carbonate in cell culture medium with the respective precision and accuracy down to a concentration of 10.0 µg/mL for Bis(2-ethylhexyl) carbonate, corresponding to a detection limit of 0.025%. No Bis(2-ethylhexyl) carbonate could be detected in the skin penetration samples up to a skin exposition time of 24 h. Therefore, Bis(2-ethylhexyl) carbonate is not expected to penetrate the human skin. Comparable results are likely for animal organism.
It can be assumed that the test substance has a low potential to cross biological membranes.
Moreover, biotic degradation of the readily biodegradable substance in water leads to relatively low concentrations in the aquatic environment. Taking also into account the calculated high Henry's Law constant (criteria for the vapor pressure of the solution in water) Bis(2-ethylhexyl) carbonate is rapidly removed from the aquatic environment and direct and indirect exposure of the aquatic compartment is low.
Summarising, Bis(2-ethylhexyl) carbonate has a low potential to cross biological membranes and direct and indirect exposure of the aquatic compartment is unlikely.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
