Hydrolysis testing with the test substance
is technically not feasible, as the test item has very low water
solubility (ref. IUCLID Section 4.8. "Water solubility").
The performance of a hydrolysis as a
function of pH test is scientifically not justified.
REACH Regulation (EC) No 1907/2006, Annex
VIII, Sect.9.2, Col. 2, states as follows:
“ 18.104.22.168: The study does not need to be
conducted if the substance is readily biodegradable, or highly insoluble
in water. ”
Since the test substance
1,1’-(1,1,2,2-tetramethylethylene)dibenzene is practically insoluble in
water, testing of hydrolysis behaviour of the test substance is
considered scientifically not justified.
