EC number: 271-013-9 | CAS number: 68513-69-9 A complex residuum from the distillation of the products from a steam-cracking process. It consists predominantly of aromatic and unsaturated hydrocarbons having carbon numbers greater than C7 and boiling in the range of approximately 101°C to 555°C (214°F to 1030°F).

Justifications and discussions
- Category definition:
- LOA Category G ‘Fuel oils’
- Category rationale:
- The ‘fuel oils’ category covers hydrocarbon streams typically produced by the distillation of products from a steam cracking process, by the distillation of products from an ethylene manufacturing process, obtained as the residual fraction from the distillation of the products of a steam cracking process, or produced by pyrolysis. Imported streams will need to confirm that they meet the chemical description and are in domain. Category members contain predominantly higher-boiling hydrocarbons, mostly cyclic olefins and aromatics, but at varying concentrations. These hydrocarbon streams have a carbon number distribution that is predominantly C8 and higher. Companies importing streams will need to confirm that such streams meet the chemical description and are in domain.
By definition, from the category, these streams have overlapping hydrocarbon compositions, within a defined range, and hence, will have similar properties. It is therefore reasonable to assume that the components of fuel oils will behave in a reasonably predictable manner, and with respect to phys-chem and environmental fate and effect properties read-across is valid.
With regard to mammalian endpoints, category members are viscous liquids with skin the primary route of exposure. The short term toxicity is driven by skin contact and potential irritation. The longer term health effects will be driven by inhalation as a route of exposure and effects and the classification of these streams will be driven by the content of benzene (when present at more than 0.1%) and toluene (when present at more than 5%) while their boiling range (130-400°C) indicates the probable presence of 3-7 ring PAH and supports overall classification Carc Cat 2/R45. Naphthalene (and other PAHs/PNAs) is regulated as a Category 3 carcinogen in the EU and is harmful by ingestion.
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.
