The results indicate that 1,1’-isopropylidenebis(p-phenyleneoxy)dipropan-2-ol
will not persist in the atmosphere as it will be removed via
reaction with photochemically-generated hydroxyl radicals. An
atmospheric half-life of 1.542 hrs will be used in EUSES. It should be
noted that this value is only an estimation of the photodegradation of
the substance in the vapour phase and not of adsorbed substance on
airborne particles. The importance of this cannot be quantified in
Information on photodegradation in water
and soil is not available.
Information on the hydrolytic break-down
of the substance as a function of pH is available through the results of
a preliminary test (Tier 1) according to OECD 111 at pH values normally
found in the environment (pH 4 -9). At each pH value a degree of
hydrolysis of < 10% was observed after 5 days. According to the
guideline, performance of the main study (Tier 2) was not required.
The half-life time of the test substance
at 25°C was > 1 year at pH4, pH7 and pH9.
