Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
For substances covered by Annex VIII to REACH short-term toxicity testing on fish, invertebrates (preferably Daphnia), growth inhibition study on aquatic plants (preferably algae) and microorganisms are required.
The tests required to fulfil the ANNEX VIII were performed on a similar substance 01 (read-across from supporting substance -structural analogue or surrogate).
Fish
After a range finding a limit test performed according to OECD203 was performed with carp exposed to 100 mg/L in a static system, with only one death observed.
Aquatic invertebrates
No daphnids became immobile during the 48 hour test period, according to OECD202.
Aquatic algae
Algal growth was almost completely reduced at the highest concentration of 100 mg/L after indirect exposure, in atest performed according to OECD201.
More than 70% of the reduction of growth rate was related to absorption of wavelengths by the colour of the test solutions at the concentrations up to and including 100 mg/L, the maximum concentration to be tested.
Microorganisms
Under the conditions of the OECD 209 test, was not toxic to waste water (activated sludge) bacteria at a concentration of 100 mg/L (3h).
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).
