Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 aquatic toxicity studies on analogues show no effects up to maximum solubility level in daphnia medium. Therefore, in view of absence of toxicity related to the sodium cation, it is expected that NaDNNSA would show no adverse effects at concentrations up to the water solubility. A read-across from the source chemicals to NaDNNSA for the daphnia and algae toxicity endpoint is considered appropriate.
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 6.4, a valid BCF QSAR showed that the BCF is expected in the range of 10 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.
