The biodegradability test performed according to OECD guideline
301F showed that more than 60% of the test substance was degraded, but
failed to pass the 10-day window. Thus, the substance cannot be
considered as readily biodegradable, but as (inherently) biodegradable.
Persistence in the environment is therefore not assumed.
The abiotic degradability was investigated with a hydrolysis
study, which showed that the test substance is not stable at pH 7 and 4
at 25 °C (t1/2 = 41.9 and 82.4 days).
Based on the information from biodegradation and hydrolysis tests
it has to be assumed that the test substance is not persistent in the
environment as biotic and abiotic degradation was observed.
Due to the logKow (3.45) of the test substance and the
experimentally established bioaccumulation potential in fish (BCF =
158), it can be concluded that oxybenzone has a low bioaccumulation
potential in aquatic and terrestrial species.
Based on QSAR estimates the adsorption coefficient to organic
matter was estimated being in the range of 2 .98 - 3.44 (as log KOC).
This indicates that the substance has a low mobility potential in soil
and sediment according to the classification scheme of McCall et al.
Furthermore oxybenzone is expected to have a low volatility under
environmental conditions (Henrys Law Constant: 1.52E-3 Pa-m³/mole,
