Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The lowest acute value is found for algae, the ErC50 for the substance is predicted to be3.7 mg/L. The one for Daphnia is 10.3 mg/l.
Since the acute EC50 values are > 1 mg/L, the substance does not need to be classified for acute toxicity according to Regulation 1272/2008/EC (CLP; Table 4.1.0; a).
The only available chronic value is the predicted chronic value (growth rate) of algae being 1.3 mg/L.
According to CLP Figure 4.1.1, the chronic classification has to be determined based on this chronic value according to Table 4.1.0, (b) ii (as the substance is readily biodegradable) and based on the available EC50 value for algae and environmental fate data according to Table 4.1.0, (b) iii. The most stringent outcome should be leading:
- As the chronic value is > 1 mg/L, the substance does not need to be classified for chronic toxicity based on this available chronic value.
- As the substance has a log Kow < 4 and is readily biodegradable, the substance does not need to be classified for chronic toxicity based on the available EC50 value for algae.
Overall, it can be concluded that the substance does not need to be classified for environmental hazards according to Regulation 1272/2008/EC (CLP) and its amendments.
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.
