Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Water solubility is 494 g Cobalt(2+) disulfamate/L at 19.3°C
Expected to be readily soluble under TDp as well
Molecular weight is 251.1 g/mol
The acute and chronic ERVs for the cobalt ion are 90.1 μg/L and 4.9 μg/L respectively, and are corrected for molecular weight (MW) to substance-specific ERVs using the following equation:
ERVsubstance=ERVCo×MWsubstance/ (n×MWCo)
where n is the stoichiometric number of Co atoms in the substance molecule. Substance-specific ERVs are:
Acute ERV: 383.9 μg/L
This is <1mg/L; hence, C&L as Acute Aquatic Cat. 1
The EU CLP guidance document (ECHA, 2011) permits consideration of the “rapid removal” and sequestration of metals in the environment much the same way as the concept of “rapid degradation” is considered for organic chemicals. To indicate “rapid removal’ for a metal, it is assumed that one must demonstrate greater than 70% removal of soluble metal within 28 days of addition to the water column, as is the case with organic compounds. Furthermore, one must demonstrate that the potential for metal remobilisation from sediments is limited, for example by changes in metal speciation, remineralisation and permanent burial in the sediment. If these conditions are met, the metal is considered “rapidly removable” and poses little environmental risk. Results of modelling using the UWM indicate that the cobalt ion satisfies the requirements for “rapid” metals removal, i.e. > 70% removal from the water column in 28 days, and the demonstration of limited sediment remobilisation potential under most environmental conditions. Based on this evaluation the Chronic ERV: 20.9 μg/L– between 10 and 100μg/L so Chronic 2
Proposed self-classification for cobalt(2+) disulfamate in accordance to regulation (EC) No 1272/2008
“acute aquatic hazard Cat. Acute 1”
“Long-term aquatic hazard Cat. Chronic 2”
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).
