Additional information
In accordance with section 2 of REACH Annex XI, the acute oral toxicity study (required in section 8.5 of Annex VII) cannot be conducted as a consequence of the physical properties of the substance.
The material is a bulk metal and as such cannot be used for toxicity testing in this form. A powder form of the test material can be generated; however this reacts in water to emit flammable gases. Consequently, the powder form is also unsuitable for toxicity testing.
Justification for selection of acute toxicity – inhalation endpoint
In accordance with section 2 of REACH Annex XI, the acute inhalation toxicity study (required in section 8.5.2 of Annex VIII) cannot be conducted as a consequence of the physical properties of the substance.
The material is a bulk metal and as such cannot be used for toxicity testing in this form. A powder form of the test material can be generated; however this reacts in water to emit flammable gases. Consequently, the powder form is also unsuitable for toxicity testing.
Justification for selection of acute toxicity – dermal endpoint
In accordance with section 2 of REACH Annex XI, the acute dermal toxicity study (required in section 8.5.3 of Annex VIII) cannot be conducted as a consequence of the physical properties of the substance.
The material is a bulk metal and as such cannot be used for toxicity testing in this form. A powder form of the test material can be generated; however this reacts in water to emit flammable gases. Consequently, the powder form is also unsuitable for toxicity testing.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, in the absence of test data the test material does not require classification for acute oral, dermal or inhalation toxicity.
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.
