Additional information
Conclusion on classification
The Cobalt-constituent of the substance is inorganic and therefore, biodegradation is not applicable. However, the citrate-constituent is readily biodegradable. Available data on bioaccumulation indicate a moderate bioaccumulation potential.
The most sensitive reliable acute aquatic value with a standard test species is an EC50 of 1.16 mg/L (Daphnia, read-across).
The most sensitive reliable chronic toxicity value is 0.016 mg/L (Daphnia, read-across). Thus, the substance is classified Aquatic chronic 2 according to EU GHS, and classified R 51/53 according to DSD/DPD.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.
