Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The solubility of trichromium dicarbide is very low. The water solubility of trichromium dicarbide is <0.5 mg/L (OECD 105 test, 72 h, quantification limit (H.C. Starck GmbH 2012)).The solubility of chromium from chromium oxide in chronic T/D test is<0.01microg/L(Hedberg and Odnevall Wallinder 2012), and from the reaction mass of heptachromium tricarbide and trichromium dicarbide (acute T/D test) <1 microg/L (quantification limit) (Jiang et al. 2011). The amount of dissolved ionic species is so low that it does not significantly contribute to the environmental chromium concentrations in air, water, sediment or soil. The resulting levels are also far below toxic concentrations.
The results on the distribution obtained with soluble chromium compounds are not directly relevant for the assessment of trichromium dicarbide. However, detailed information on the environmental distribution of trivalent chromium compounds are presented in the ICDA documentation on environmental assessment of chromium (ICDA 2010).
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.
