Key value for chemical safety assessment
Additional information
The reliability of the studies was judged as not assignable (score 4) because of the lack of study details. This would represent an obstacle to use the studies results for the classification and labelling (C&L) of the substance. However, the studies were previously presented within the context of a regulatory framework and the lack of details available to us does not necessarily mean that they have to be discarded.
Therefore, even with the above mentioned limitations, the studies were considered in order to define the C&L of the substance.
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.
