Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term toxicity results for Daphnia and algae are available for the substance. The 48h-EC50 for Daphnia magna was 5.43 mg/L. The 72h-ErC50 and 72h-ErC10 for algae are 21.7 mg/L and 11.4 mg/L, respectively.
Short-term (acute) aquatic hazard
Since the acute EC50 values are > 1 mg/L, the substance does not need to be classified according to the CLP Regulation.
Long-term (chronic) aquatic hazard
The only available chronic value is the 72h-ErC10 for algae. 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 Daphnia and environmental fate data according to Table 4.1.0, (b) (iii). The most stringent outcome is leading:
- As the chronic value is > 1 mg/L and the substance is readily degradable, it does not need to be classified based on this available chronic value.
- As the substance has a log Kow of => 4 (i.e. 4.2) and the EC50 value for the other trophic level is >1 but <= 10 mg/L, the substance needs to be classified as Chronic Cat. 2 based on this EC50 value.
It is therefore concluded that the substance needs to be classified as Chronic Cat. 2 (H411) according to the CLP Regulation.
GHS
As the 48h-EC50 for Daphnia magna is >1 but <= 10 mg/L, the substance additionally needs to be classified as Acute Cat. 2 (H401) according to GHS.
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).
