Any other information on results incl. tables
At the three different pH, after 5 days of incubation at 50 ± 0.5°C, less than 10% of hydrolysis was found in each case. Therefore, according to the criteria given in the guideline 111, no main study was required to conclude that the half-life time of the test substance is superior at 1 year.
PERFLUOROHEXYLETHYLIODIDE : Hydrolysis: half-life time > 1 year
