Based on a constituent approach including all constituents equal or
above 1%, which biodegradation are predicted by using the expect system
CATALOGIC Kinetic 301F v.13.16, the Biochemical Oxygen Demand after 28
days is estimated 74% ± 4%, and therefore the UVCB Petitgrain oil
concluded as meeting the criteria to be qualified as readily
biodegradable. All the constituents are within the applicability domain
of the model. In addition, 5 among 12 are part of the training set and
confirm that the predicted biodegrabilities are equivalent to test
results. For Pinene alpha & beta (1.2%) for which the model predicted
only 55% biodegrability, whereas ready biodegradable could be concluded
based on the OECD301D test result reported on ECHA website for the
registered substance (-)-pin-2(3)-ene. As it is not possible to
overwrite the prediction, this results in an underestimation of the
overall biodegradability of the essential oil.
