Additional information
Acute oral toxicity
No data are available. A waiver is appropriate for this endpoint in accordance with Column 2 of REACH Annex VII as the substance is corrosive. It is noted that sodium hydrogen difluoride is classified for acute toxicity under CLP.
Acute inhalation toxicity
No data are available. A waiver is appropriate for this endpoint in accordance with Column 2 of REACH Annex VIII as the substance is corrosive.
Acute dermal toxicity
No data are available. A waiver is appropriate for this endpoint in accordance with Column 2 of REACH Annex VIII as the substance is corrosive.
Justification for selection of acute toxicity – oral endpoint
A waiver is proposed in accordance with Column 2 of the Annex VII REACH data requirements (specific rules for adaptation from Column 1). A study does not need to be conducted because sodium hydrogen difluoride is classified as Corrosive and additionally is already classified as Toxic if swallowed (H301) under CLP.
Justification for selection of acute toxicity – inhalation endpoint
A waiver is proposed in accordance with Column 2 of the Annex VIII REACH data requirements (specific rules for adaptation from Column 1). A study does not need to be conducted because sodium hydrogen difluoride is classified as Corrosive.
Justification for selection of acute toxicity – dermal endpoint
A waiver is proposed in accordance with Column 2 of the Annex VIII REACH data requirements (specific rules for adaptation from Column 1). A study does not need to be conducted because sodium hydrogen difluoride is classified as Corrosive.
Justification for classification or non-classification
Sodium hydrogen difluoride is classified according to the CLP Regulation (EC) 1272/2008 in Acute Toxicity Category 3 (H301). No change is proposed to the existing classification.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
