Additional information

Substance is a hydrocarbon UVCB, meaning that its composition is variable and the exact proportions of individual components are not known. Hence, derivation of a PNEC using conventional methods of applying assessment factors to toxicity data are not appropriate. Instead, the hydrocarbon block method is used for environmental risk assessment (see REACH guidance, R7, app.13-1). See Product Library tab in “assessment report. PetroRisk information excel” spreadsheet attached to Section 13 for PNEC values. Aquatic PNECs for hydrocarbon blocks have been derived using the HC5 statistical extrapolation method and the target lipid model using representative structures. Given the large database of organisms included in the target lipid model, an assessment factor of one has been applied to the HC5. Therefore, it is not possible to identify a single, representative PNEC for this complex substance. 

C14-20 Aliphatics (≤2% aromatic) have been shown to have a very low toxicity towards organisms, with NOELR values equal or higher than 1000 mg/l for all species (algae, crustacean and fish).

Conclusion on classification

C14-20 Aliphatics (≤2% aromatic) are not classified for the environment.
