Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Bacterial reverse mutation assays (Ames test) have shown the structurally related substances not to induce reverse mutation in Salmonella typhimurium or Escherichia coli. In addition, structural analogues of the substance neither induced chromosomal aberrations in Chinese hamster ovary cells after in-vitro treatment nor induced mutation in mouse lymphoma L5178Y cells.
REACH Regulation 1907/2006 (Annex VIII, 8.4 Column 2) states that appropriate in-vivo mutagenicity studies should be considered in those cases of a positive result in any of the in vitro genotoxicity studies. In vitro investigations were negative and in vivo studies available for structurally related substancs are also negative, so performance of additional in vivo studies is regarded as inappropriate and not in line with current concerns regarding animal welfare and the use of animals in scientific experiments.
Short description of key information:
Genetic toxicity in-vitro - Negative, based on several studies available on structurally related substances.
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Non-classification is justified on the basis of negative findings with structurally related substances in in-vitro and in vivo tests for gene mutation / mutagenicity.
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.
