Sodium does not become available in the body due to his quasi-instantaneously degradation on contact with moist skin or mucous membranes (it becomes sodium hydroxide and hydrogen). On the basis of this degradation, sodium is corrosive (due to the sodium hydroxide) and is classified in the CLP Regulation No 1272/2008 Annex VI as corrosive.
Consequently, no DNEL, for acute and systemic effect, can be derived and a qualitative approach will be performed both for exposure assessment and risk characterisation.
