Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Does not accumulate in organisms.
Key value for chemical safety assessment
Additional information
The solubility of Phthalocyanines in octanol and in water is extremely low. Therefore bioaccumulation of the target substance CAS 16040-69-0 is not probable. To assess the bioaccumulation potential for the target substance, read across was performed to structurally similar substances.
Low bioaccumulation potential of the target substance CAS 16040 -69 -0 is supported by two bioaccumulation studies available for the structurally similar substances CAS 147-14-8 and CAS 1328-53-6 respectively. The test set up was comparable to the specifications given in the OECD guideline 305. Cyprinus carpio was exposed to different concentrations of the substances for 6 weeks in a flow-through system. A BCF < 3.6 was determined for a concentration of 0.06 mg/l CAS 147-14-8. Whereas a concentration of 0.6 mg/l resulted in a BCF of <0.33 (MITI 1979). Comparable results were obtained for CAS 1328-53-6. Fish were exposed to 0.1 mg/l and 0.01 mg/l of CAS 1328-53-6. BCFs of 4.8 and <2.1 were determined for the respective concentrations (MITI 1979).
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.
