Additional information

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.

Conclusion on classification

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.
