Endpoint summary
Administrative data
Description of key information
Acute toxicity data for Bis(2-ethylhexyl) carbonate are available for the oral and the dermal route. Acute animal studies by inhalation route are scientifically unjustified as inhalation is not a relevant route of exposure to Bis(2-ethylhexyl) carbonate. This applies to both workers and the general population and is due to the physicochemical properties of the substance and the nature of the products where it is used.
In rats, the substance is practically non-toxic with oral and dermal LD50 values of > 2 000 mg/kg bw. Neither the oral nor the dermal application of 2000 mg/kg bw induced deaths, clinical signs, changes in body weight or treatment related necropsy findings.
Key value for chemical safety assessment

Animals then were observed for 14 days.
Dermal LD50 Males and Females > 2000 mg/kg bw
No mortality occured in this limit test.
No clinical signs of toxicity were observed throughout the observation period.
The skin at the application site showed no changes.
Weight gain of all animals was within the expected range.
No test substance related gross pathological changes were found in any animals.
Based on the available information, Bis(2-ethylhexyl) carbonate is non-toxic by oral and dermal administration in rat. There are no data gaps in acute toxicity. Even though there is no information on acute inhalative toxicity, there is no reason to believe that there is acute toxicity relevant to humans for this route of exposure. Even though there is no information on acute toxicity in humans, there is no reason to believe that the low acute toxicity observed in experimental animals would not be relevant for human health.
Justification for selection of acute toxicity – oral endpoint
study according to OECD and EU guidelines, no deviations, GLP
Justification for selection of acute toxicity – dermal endpoint
study according to OECD and EU guidelines, no deviations, GLP
Justification for classification or non-classification
Bis(2-ethylhexyl) carbonate does not comply with the classification requirements regarding acute toxicity outlined in regulation (EC) No 1272/2008 or the former European directive on classification and labeling Directive 67/548 EEC. There is no evidence on relevant intrinsic acute toxic activity of Bis(2-ethylhexy) carbonate. In rats, oral as well as dermal LD50 values are greater than 2000 mg/kg bw based on a.i.. Data on inhalative acute toxicity are not availabe. However, acute animal studies by inhalation route are scientifically unjustified as inhalation is not a relevant route of exposure to Bis(2-ethylhexyl) carbonate.
