Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
All calculated PNEC values are based on reliable studies according to the respective OECD guidelines. As no relevant data are available on the toxicity of CTC towards soil and sediment organisms and no significant exposure is anticipated from physico-chemical properties and present pattern of uses, no PNEC is derived for these compartments.
Conclusion on classification
Carbon tetrachloride is considered as not readily biodegradable and has no significant potential for bioaccumulation with low bioconcentration factors measured in aquatic species. Carbon tetrachloride is harmful to fish, daphnia and algae with acute EC50 in the range 10 -100 mg/L. Chronic toxicity data are available for the 3 trophic levels with NOEC > 1 mg/L.
On this basis, environmental classification for carbon tetrachloride is not required neither according to the Dangerous Substance Directive, nor according to the CLP 286/2011 Regulation.
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.
