Description of key information

Inorganic oxides in which the inorganic element is in its highest possible oxidation state are incapable of further reaction with oxygen and can thus be designated as non-flammable (Endpoint Specific Guidance Chapter R.7A, p. 123). 

Key value for chemical safety assessment

Additional information

Removing electrons from NaOH is not obvious and no information is found what stable molecule could be produced. The sodium and hydroxide ions are quite stable in solution.
