Given the predicted primary half-lives in water, soil, and sediment
compartments for the parent constituents and the associated PBT
assessment for the predicted metabolites identified, it is concluded
that the substance is not persistent, and as such simulation studies in
soil or sediment are not required and will not provide additional
information as to the PBT/vPvB properties of the substance or its
In accordance with REACH Annex IX ,
information on the simulation testing in water, sediment, and soil
should be provided to assess the potential persistence of the substance
and its associated conclusion as it relates to PBT/vPvB assessment.The
substance is a hydrocarbon UVCB. Standard tests for this endpoint are
intended for single substances and are not appropriate for this complex
However, this endpoint is characterised using quantitative structure
property relationships for representative hydrocarbon structures that
comprise the hydrocarbon blocks used to assess the environmental risk of
this substance with the PETRORISK model (see Product Library in
PETRORISK spreadsheet attached in IUCLID section 13).
For purposes of PBT assessment, the substance has been assessed using a
combination of QSAR predictions and confirmatory experimental testing
for representative constituents using a hydrocarbon block approach. For
details see report titled 'Evaluation of PBT for Petroleum Substances'
in IUCLID section 13.
For the oxygenated fraction (0 - 5%, 1% typical), experimental OECD 301F
data exists for C8 - C13 iso-alcohols (EC #271-231-4, 271-233 -5,
271-234-0, 271-360-6, and 271-235-6). These substances are considered
readily degradable (BOD > 60% in 28 days). As a result, this fraction is
not further evaluated for persistence in water, soil, and sediment, in
accordance with Annex XI, and X column 2 adaptations for readily
As part of the exposure assessment, half-lives
in air, water, soil, and sediment were calculated using BioHCWin within
the PETRORISK model (see Product Library in PETRORISK spreadsheet
attached to IUCLID section 13).
