Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
Classification related key information
The concept of ready biodegradability does not apply to inorganic substances.
Significant bioaccumulation in biota is not expected for this substance (see IUCLID section 5.3).
Acute toxicity:
- Fish: LC50 (96h) ≥ 100 mg/L (nominal); read across
- Aquatic invertebrates: EC50 (48h) = 91 mg/L (nominal); read-across
- Algae: EC50 (72 h) = 150 mg/L (nominal); read across
Chronic toxicity:
- Aquatic invertebrates: NOEC (21 d): 10 mg/L (nominal); read across
- Algae: NOEC (72 h) = 100 mg/L (nominal); read across
Conclusion on classification
The substance has a low potential for bioaccumulation. Based read-across from supporting substance (structural analogue), the acute aquatic toxicity L(E)C50 values are ≥ 91 mg/L (nominal) and above for fish, aquatic invertebrates and algae, and the NOEC in a chronic toxicity study on Daphnia magna is 10 mg/L. Thus the substance does not need to be classified and labelled according to the 6th ATP of Regulation (EC) No.1272/2008 (CLP).
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.
