Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
When exposed to humidity, disodium oxide (n°CAS 1313 -59 -3) instantaneously decomposes in sodium hydroxide (n°CAS 1310 -73 -2), following the equation:
Na2O + H20 -> 2NaOH
This reaction is verified weekly in a laboratory by pH measures (pH > 12 after reaction).
Testing for hydrolysis is then technically impossible and scientifically unjustified: instantaneous decomposition of Na2O in presence of humidity do not allow hydrolysis testing.
Additional information
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.
