Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence (P)
The RA substance Cu Phthalocyanine (Phthalocyanine blue) is insoluble in water, and is classified as "not readily biodegradable" by the results of biodegradation test conducted as SIDS testing. Testing has shown the water solubility of Fe phthalocyanine (FePC) to be 0.018 mg/l, confirming the low solubility. It can be assumed that FePC is not readily biodegradable based on read-across from Cu phthalocyanine. Conclusion: FePC is P.
Bioaccumulation (B)
The log10 Pow for FePC has been calculated to be 2.8. As this is well below the accepted threshold of 4.5 that would flag it as a substance that would potentially bioaccumulate, FePC can be considered as not having the potential to bioaccumulate. Conclusion: FePC is not B.
Toxicity (T)
Testing has shown that Fe phthalocyanine is non-toxic to fish and terrestrial plants. Conclusion: FePC is not T.
The overall conclusion is that, although FePC is considered persistent, toxicological tests showed low toxicity and it is not considered to have the potential to bioaccumulate. It is therefore concluded that FePC is not PBT and that no further testing is needed at present, especially considering its low potential for exposure and the low tonnage band.
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).
