Additional information
Substance is a hydrocarbon UVCB: The hydrocarbon block method is used for environmental risk assessment (see REACH guidance, R7, app.13-1). 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. Given the large database of organisms included in the target lipid model, an assessment factor of one has been applied to the HC5. Soil PNECs for hydrocarbon blocks have been derived using aquatic PNECs and the equilibrium partitioning method (EqP) using representative structures.
Conclusion on classification
The available data on the source substances within an analogue approach do not support classification of Hydrocarbons, C5-C6, n-alkanes, isoalkanes, < 5% n-hexane as hazardous to the aquatic environment. However, based on the classification of its constituents pentane (Index No 601-006-00-1) and hexane, reaction mass of isomers (containing < 5 % n-hexane (Index No 601-007-00-7) as laid down in Annex I of Directive 67/548/EEC and Annex VI of Regulation (EC) No 1272/2008 Hydrocarbons, C5-C6, n-alkanes, isoalkanes, <5% n-hexane have to be classified as hazardous to the aquatic environment (aquatic chronic 2).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
