Testing for hydrolysis is waived based on following justification:
according to column 2 of REACH Annex VIII, a hydrolysis study does not
need to be conducted for highly insoluble substances. Zirconium dioxide
is such a substance, with a water solubility of < 55 µg/L. Furthermore,
according to the guidelines, the concentration of test samples should
not exceed half the water solubility of the test substance. The water
solubility is extremely low. An analytical method to support the
hydrolysis study at this low concentration level is not available: the
water solubility is smaller than the limit of detection of the
analytical method. The test on the hydrolysis of the substance can
therefore not be performed.
