GHS

General Information

Name:
Sodium hydroxide
Implementation:
EU
Remarks:
Sodium hydroxide is listed on Annex VI of Regulation (EC) No 1272/2008 (CLP). The harmonized classification and labelling according to this CLP regulation is given in this section. However, in addition it is proposed to classify the substance as: Corrosive to metals; category 1.
The Precautionary Statements mentioned in section 2.1 are applicable for industrial use of the substance NaOH. Other or additional Precautionary Statements may be more appropriate for professional and/or consumer use of NaOH.
