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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The key ecotoxicity values to assess the aquatic toxicity of the registered substance are as follow:
- Short-term toxicity to fish: 96h-LC50 = 3.2 mg/L
- Long-term toxicity to fish: 14d-NOEC = 0.35 mg/L
- Short-term toxicity to aquatic invertebrates: 48h-EC50 = 2.9 mg/L (lowest acute E(L)C50 value)
- Long-term toxicity to aquatic invertebrates: 21d-NOEC = 0.32 mg/L (lowest chronic NOEC value)
- Toxicity to aquatic algae and cyanobacteria: 72h-EC50 > 4.8 mg/L and 72h-NOEC = 0.59 mg/L
Based on these results, the lowest acute E(L)C50 is above 1 mg/L and the lowest chronic NOEC value is > 0.1 and < 1 mg/L. Based on the experimental conditions of the studies, aquatic invertebrates were found to be the most sensible species in both acute and chronic tests.
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation.
Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 above 1 mg/L.
Chronic aquatic hazard: category 2. Reasoning: adequate chronic toxicity data are available, the substance is considered as not rapidly degradable and the lowest chronic NOEC value is between 0.1 and 1 mg/L.
Additional information
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.
