Additional information

The hydrocarbon block method has been used for environmental risk assessment (see REACH guidance, R7, app.13-1). Aquatic PNECs for hydrocarbon blocks 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. Given the large database of freshwater organisms included in the target lipid model, an assessment factor of one has been applied to the HC5.

Conclusion on classification

According to the CLP legislation (2008) n-hexane is classified for the environment as chronic category 3 with the hazard statement H411: Toxic to aquatic life with long lasting effects.
