Additional information
In accordance with section 2 of REACH Annex XI, skin irritation/corrosion studies (required in section 8.1 of Annex VII and 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 eye irritation endpoint:
In accordance with section 2 of REACH Annex XI, eye irritation studies (required in section 8.2 of Annex VII and 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 skin or eye irritation.
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.
