Substance is a hydrocarbon UVCB. Standard
tests for this endpoint are intended for single use substancesand are
not appropriate for complex substances. The hydrocarbon block method is
used for environmental risk assessment (see REACH guidance, R7,
app.13-1). PNECs for hydrocarbon blocks have been derived using aquatic
PNECs and the equilibrium partitioning method (EqP) using representative
structures. The aquatic PNECs have been derived using the HC5
statistical extrapolation method and the target lipid model using
representative structures. See "Product Library" tab in PETRORISK
spreadsheet attached to IUCLID Section 13 of the dossier. Given the
large database of organisms included in the target lipid model, an
assessment factor of one has been applied to the HC5.
Hydrocarbons, C11-C12, isoalkanes, <2%
aromatics, does not demonstrate acute fish and invertebrate toxicity,
and alga toxicity at loadings up to 1000 mg/L. Its log Kow value is >4.
It is not readily biodegradable. Invertebrate NOELR values are between
0.01 and 0.1 mg/L.
