Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Data on short-term ecotoxicity are available on the substance that, according to QSAR Estimation (EPISUITE, 2016) is considered non readily biodegradable.
a) Acute (short-term) aquatic hazard
Category Acute 1:
< 1 mg/L 96 hr LC50 (for fish) and/or
< 1 mg/L and/or 48 hr EC50 (for crustacea) and/or
< 1 mg/L 72 or 96 hr ErC50 (for algae or other aquatic plants)
b) Long-term aquatic hazard
(iii) Substances for which adequate chronic toxicity data are not available
Category Chronic 1:
< 1 mg/L 96 hr LC50 (for fish) and/or
< 1 mg/L and/or 48 hr EC50 (for crustacea) and/or
< 1 mg/L 72 or 96 hr ErC50 (for algae or other aquatic plants)
Category Chronic 2:
>1 to ≤10 mg/L 96 hr LC50 (for fish) and/or
>1 to ≤10 mg/L 48 hr EC50 (for crustacea) and/or
>1 to ≤10 mg/L 72 or 96 hr ErC50 (for algae or other aquatic plants)
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log Kow ≥ 4).
Category Chronic 3:
>10 to ≤ 100 mg/L 96 hr LC50 (for fish)and/or
>10 to ≤ 100 mg/L 48 hr EC50 (for crustacea) and/or
>10 to ≤ 100 mg/L 72 or 96 hr ErC50 (for algae or other aquatic plants)
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log Kow ≥ 4).
The short-term ecotoxicity values are available for two throphic levels:
EC50 (48h) invertebrate Daphnia: > 100 mg/L
EC50 (7 days) aquatic plants: 134 mg/L (growth rate), NOEC 14.9 mg/L (growth rate).
The acute aquatic toxicity based on the lowest of the available toxicity values is 134 mg/L (Daphnia is > 100 mg/L).
The only available growth rate aquatic plant long term toxicity data should be supported by a long term toxicity data on another thropic level (TGD Part II).
As conclusion, according to the classification criteria of the CLP regulation n. 1272/2008, the registered substance is not classified for the environment.
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.
