Additional information
It is technically not possible to conduct the study as a consequence of the properties of the substance (mixing with water causes danger of explosion, hydrolytically unstable substance and quasi-instantaneously decomposed in contact with moist skin or mucous membranes to form Sodium Hydroxide and Hydrogen).
Short description of key information:
It is technically not possible to conduct the study as a consequence of the properties of the substance (mixing with water causes danger of explosion, hydrolytically unstable substance and in contact with moist skin or mucous membranes, sodium becomes corrosive).
Furthermore, there is sufficient data on the degradation products (the evaluation of the toxicological properties of sodium hydroxide will be independently considered under its proper registration procedure)
Justification for classification or non-classification
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.
