Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The environmental classification of the test
substance is currently not harmonised
according to the CLP Regulation (EC) 1272/2008. Based on available acute
aquatic toxicity data, the lowest valid effect concentration for
freshwater aquatic organisms is 29 mg/L (72-h EC50 for algae). Based on
the available acute data, the substance should not be classified for
acute toxicity following Annex I, table 4.1.0 a of the CLP regulation
(there are no acute values ≤ 1 mg/L).
In the algal growth inhibition study, the NOErC for algae was 3.2 mg/L. No other long-term values are available. Following Annex I, therefore the substance's classification for chronic toxicity should be determined based on the acute toxicity values, following table 4.1.0 b (i and iii) of the CLP Regulation. Taking into account the acute toxicity data as well as the fact that the substance is not rapidly degradable and its log Pow is < 4, the substance should be classified as Aquatic Chronic 3 under the CLP Regulation.
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.
