Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

< 12 µg/L at 23°C
Key value for chemical safety assessment
Additional information
The determination was carried out by flask method based on OECD Guideline 105 the ETAD method. The concentration of the pigment in water was determined by HPLC-UV.
The method was developed by intensive cooperation with the ETAD (Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers) and is regarded as acceptable for pigments by authorities.
The quantification limit (LOQ) was defined as 2 times the detection limit therefore the LOQ is 12 μg/L.
As the test compound might release Cu ions in aquatic test systems a dissolution study is proposed to investigate the potential Cu release.
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.
