Additional information
Justification for classification or non-classification
Classification is not warranted because no mortality or toxicologically significanr observations were reported at a single oral dose of 2000 mg/kg of the test material (containing 65% 1,5-Naphtalene disulfonic acid and 10.8% sodium).
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.
