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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Hydrolysis
The main components of the submission substance are of inorganic nature, without any hydrolysable groups present. The substance finally will be completely dissociated into ions.
Biodegradation
The main components of the submission substance are of inorganic nature - no study on ready biodegradability has to be performed if the substance is inorganic. For the organic complex ligand humate, which comprise <1% (w/w) of the submission substance, a screening study showed the test material to be not ready biodegradable.
Bioaccumulation
According to Regulation (EC) No. 1907/2006, Annex IX, No. 9.3.2., Column 2, further bioaccumulation studies need not to be conducted if the substance has a low potential for bioaccumulation.
The main components of the submission substance are of inorganic nature, are highly hydrophilic and will ultimately dissociate into ions.
The organic complex ligand humate, which comprise <1% (w/w) of the submission substance, also is highly hydrophilic, with a logPow of -2.16.
As the submission substance is of high hydrophilicity, no further testing is required. In addition, the high molecular weight of the humate ligand (approximately 5000 g/mol) strongly indicates low bioconcentration potential.
Adsorption
According to Regulation (EC) No. 1907/2006, Annex VIII, No. 9.3.1., Column 2, adsorption/desorption screening does not need to be conducted if the substance has a low potential for adsorption. As the submission substance is of high hydrophilicity, no testing is required.
The main components of the submission substance are of inorganic nature, are highly hydrophilic and will ultimately dissociate into ions. The organic complex ligand humate, which comprise <1% (w/w) of the submission substance, also is highly hydrophilic, with a logPow of -2.16. A study performed to determine Koc for the humic acid, potassium salt revealed a very low absorption coefficient.
As the submission substance is of high hydrophilicity, no further testing is required.
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.
