Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Applicant's summary and conclusion

Conclusions:
The uncertainties, which are arisen from the in vitro test results, would make desirable a verification by means of an in vivo test, as it is foreseen by the Regulation EC 1907/2006. However, toxicokinetics evidences do not support the adsorption (after oral administration) and the subsequently reaching of the target tissue by the substance, making non reliable the validated in vivo mutagenicity tests. Indeed, B.11 (In Vivo Mammalian Bone Marrow Chromosome Aberration Test) and B.12 (In Vivo Mammalian Erythrocyte Micronucleus Test) sections of the Regulation CE 440/2008 reports that: "If there is evidence that the test substance, or a reactive metabolite, will not reach the target tissue, it is not appropriate to use this test". In light of above issue, no in vivo test was performed.
