As stated in the review of BG Chemie (1994):
7. Experimental results
7.1 Toxicokinetics and metabolism
Enzymatic cleavage of carbonic acid diethyl ester occurred on incubation with homogenates of bovine kidney or mucous membrane from the small intestine. The increase in pressure caused by liberated CO2 was measured manometrically in a Warburg apparatus (Lang et al., 1966).
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): low bioaccumulation potential based on study results
As an ester diethyl carbonate may be metabolised to ethanol and CO2 in the body, in particular in the intestine or in the kidneys. This assumption may be supported by the results of Lang et al. who found the generation of CO2 when the substance was in contact with homogenates (and therefore enzymes) of bovine kidney and intestinal membrane. Carbon dioxide is a natural metabolite in the human body. Ethanol has a known toxicity profile and is also metabolised without accumulation in the body. If this metabolism takes place the risks associated with it would be limited.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
