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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
48 -h test on aquatic invertebrates: EC50 > 100 mg/l
7 -day test on aquatic plants: ErC50 > 100 mg/l
Additional information
The assessement on aquatic toxicity is based on experimental studies on aquatic invertebrates and plants.
Short-term toxicity to aquatic invertebrates
EC50 (48h) > 100 mg/l
EC0 (48h) = 100 mg/l
Toxicity to aquatic plants other than algae
Growth rate of frond number after a 7 -day exposure:
EC50 > 100 mg/l; NOEC= 100 mg/l
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.
Based on available findings in aquatic invertebrates and aquatic plants, no classification applies.
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.
