Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic Chronic 3 (H412), according to the CLP Regulation (EC 1272/2008).
Additional information
Adequate chronic toxicity data are not available for Basic Blue 140 (BBl140), therefore the aquatic toxicity assessment and classification are based mainly on the short-term toxicity data available.
Despite BBl140 has a log Pow lower than 4 (indicating a low potential for bioaccumulation) and it is not rapidly degradable.
According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50 , a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50. Data are available for fish (Danio rerio), invertebrates (Daphnia magna) and algae (Scenedesmus subspicatus).
The outcomes of the tests performed on the three trophic levels suggest that fish is the most sensitive species, thus the classification has to be based on the short-term toxicity to fish.
According to the CLP Regulation (EC 12720/2008) criteria for the identification of the classification categories for hazardous to the aquatic environment, the study about short-term toxicity to fish fixed the short-term effect level on fish between 10 and 100 mg/l.
In conclusion, the BBl140 is classified as Aquatic Chronic 3 (H412), according to the CLP Regulation (EC 1272/2008).
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.
