Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fish: LC50 (96h) between 10 and 100 mg/l
Aquatic invertebrates: EC50 (48h) > 101 mg/l
Aquatic algae: EC50 (72h) > 100 mg/l
Additional information
According to the CLP Regulation (EC 1272/2008), a substance shall be classified as category acute 1 (H400) when:
96 hr LC50 (for fish) < 1 mg/l and/or
48 hr EC50 (for crustacea) < 1 mg/l and/or
72 or 96 hr ErC (for algae or other aquatic plants) < 1 mg/l.
Moreover, if adequate chronic toxicity data is not available, a substance shall be classified as category chronic 3 (H412) when:
96 hr LC50 (for fish): 10 - 100 mg/l and/or
48 hr EC50 (for crustacea): 10 - 100 mg/l and/or
72 or 96 hr ErC (for algae or other aquatic plants): 10 - 100 mg/l
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log Kow ≥ 4).
The decision on classification was derived from available experimental data. A classification in category 3 for aquatic chronic toxicity (H412) was based on results on fish, i.e. LC50 (96 h) between 10 - 100 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
