Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
In accordance with Annex VIII, Column 2 a study on adsorption / desorption does not need to be conducted since based on the physicochemical parameters of the substance adsorption is not expected. The substance belongs to the category of phthalocyanines. Phthalocyanines resemble in structure as well as physical and chemical properties, such as the log Kow (e.g. CAS 147-14-8: log Kow of -1; CAS 28901-96-4: log Kow of -0.11). The physicochemical characteristics of phthalocyanines indicate that the substance will not adsorb to soil or suspended matter. The water solubility of the substance is very high and the resulting log Kow is negative. Therefore, adsorption of the test substance is not expected.
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.
