Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
96-h test on fish: LC50 > 100 mg/l
48 -h test on aquatic invertebrates: EC50 = 235 mg/l
7 -day test on aquatic plants: ErC50 = 318 mg/l for frond number
Additional information
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h ) for fish, EC50 (48h) for daphnia, EC50 (72 -96 h) for algae and EC50 (7 d) for other aquatic plants.
As for chronic toxicity, in case of lack of chronic data, the toxic potential is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification is 100 mg/l.
Available EC50 values are indicative of a low aquatic toxicity of test substance, implying no classification for both acute and chronic toxicity within 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.
