Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No derivation of PNEC value is necessary as the substance is imported in the EU in a volume <10 tonnes.
The outcome of daphnia tests on the test substance, DNNSA and BaDNNSA gave similar results. Therefore the read-across for toxicity to algae can be based on a study with DNNSA.
The EC50 value for daphnia is > 0.42 mg/L (based on a study with LiDNNSA, Laus 2014) . The EC50 for growth rate for algae is > 1.2 mg/L. Both values are above the anticipated water solubility of LiDNNSA.
Conclusion on classification
In none of the acute aquatic toxicity tests performed on daphnia and algae, an EC50 could be achieved within limits of solubility. Thus, based on the information available no classification for acute aquatic toxicity is derived according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC). Although the log of n-octanol/water partitioning coefficient was > 6.5 a valid BCF QSAR showed that the BCF is expected in the range of 56.2 to 70.8. Thus, the substance is also not classifiable for chronic aquatic toxicity according to CLP or DSD.
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.
