Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 harmonized according to the CLP Regulation (EC) 1272/2008. No data was available for the test substance. Data generated with the analogue substance LABS Na was considered pivotal to derive an enviornmental classifcation. This read across strategy is considered as a worst case scenario, as it is expected that the observed effects will be far above the solubility limit of the target substance. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 1.67 mg/L (96h LC50 for fish). Based on the available 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).
Based on available chronic aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 0.23 mg/L (72d NOEC for fish). Taking into account the chronic toxicity data as well as the fact that the substance is not rapidly degradable, the substance should be classified as Aquatic Chronic 2, following Annex I, table 4.1.0 b of 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.
