CAS number: -
In this study, the test item zirconium
oxide, hafnium and ytterbium doped could not be prepared in
an appropriate solvent and diluted prior to treatment. Due to the
properties of the material, the target substance was not soluble in any
of the solvents used (Aqua dest., DMSO, ethanol and acetone). No stable
suspension which is suitable for the preparation of the dilution series
could be obtained. Therefore, it was not possible to perform any further
steps in this study. Since the test item could not be prepared in an
appropriate solvent and diluted prior to treatment, it was not possible
to perform an Ames test with zirconium
oxide, hafnium and ytterbium doped. In
line with Annex
XI, section 2 of Regulation
(EC) 1907/2006 (REACH Regulation), the
performance of the study is therefore technically not feasible.
