Additional information
Justification for classification or non-classification
According to the data available and the classification criteria laid down in Regulation (EC) 1272/2008 (CLP), the test substance does not fulfill the criteria for classification. Therefore, non-classification of the test substance is warranted.
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.
