Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute toxicity information for algae and Daphnia is available. The ErC50 for Daphnia is 23 mg/l, which is lower than for algae (>100 mg/l).
Based on the lowest available acute data for Daphnia with an ErC50 value of 23 mg/L, the substance does not need to be classified for acute aquatic toxicity.
As one chronic value is available, for algae, the chronic C&L needs to be derived on both chronic and acute toxicity data and the most stringent outcome needs to be taken into consideration.
The only chronic value available is the EC10 for algae being >100 mg/L. In combination with the substance being readily degradable, the substance does not need to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) ii of the CLP Regulation. When taking into account the acute data of the other trophic level, i.e. Daphnia with an EC50 value of 23 mg/L, in combination with the substance being readily degradable and having a log Kow of 0.7, the substance also does not need to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of the CLP Regulation.
Overall, it can be concluded that the substance does not need to be classified for the environment in accordance with the criteria outlined in Annex I of CLP (1272/2008/EC) 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.
