Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Short-term aquatic toxicity:
Reliable short-term toxicity tests are available for fish, algae and for daphnia are available.
All three fish studies exposed the fish for 96h in a static system. Respective LC50 ranged from 14.8 to 21.1 mg/L. As all studies were of sufficient reliability, the study with lowest LC50 (Clariant 93.0432), i.e. 14.8 mg/L, was assigned as the key study.
In the one available acute daphnia study, Daphnia Magna were exposed for 48h in a static system. The LC50 was 7.7 mg/L.
In the one available algae study, the 72h-LC50 for growth rate was 16.06 mg/L
Long-term aquatic toxicity:
Reliable long-term toxicity tests are available for the two trophic levels algae and daphnia.
In the algae study the growth rate EC50 (72h) of the test substance was 16.06 mg/L, while the NOEC was 1.80 mg/L.
In the daphnia reproduction test, the 21-days NOEC regarding reproduction of the test substance was determined to be 1.3 mg/L.
Toxicity to microorganisms:
A reliable study assessing the toxicity to microorganisms is available.
Based on the respiration rate, the EC50 to activated sludge was determined to be 212.3 mg/L .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).
