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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to structural properties, hydrolysis is not expected.
Additionally, the test substance has a very low water solubility and therefore, the test is technically not feasible.
Biodegradation in water: screening tests
The substance is not readily biodegradable, according to OECD criteria (see IUCLID Ch. 5.2.1)
Bioaccumulation
Acumulation in aquatic organisms is not expected
Adsorption / desorption
The physio-chemical characteristics of the substance indicate that the substance will not adsorb to soil or suspended matter. The water solubility of the substance as well as the solubility in octanol and the resulting log Kow are very low.
Dispersion stability
Regardless of pH, the pigment is categorized at the 24h-sampling time as “unstable” in 10 mM Ca, representing high water hardness.
After 6h, the stability in 0 mM and 1 mM Ca was high and intermediate respectively regardless pH. At pH 4 in 10 mM ca the stability was intermediate. At all other conditions the stability was low
After 24 hours the stability for samples in 0 mM Ca became intermediate. For all other samples the stability was low
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.
