Description of key information
Additional information
Key study data are available for each relevant physicochemical endpoint for straight-run gas oils. All substances in the category are liquids (CONCAWE, 2010a) at ambient temperature (20°C) and pressure (101.3 kPa). There is no guideline method available for this endpoint and data presented are based on visual observation, supported by data on pour point and viscosity. The pour point for chemicals in this category ranges from -40 to 6°C(CONCAWE, 2010a). The boiling point for straight-run gas oils ranges from 150 to 399°C (CONCAWE, 2010a) and the density ranges from 0.8 to 0.9 g/cm3 at 15°C (CONCAWE, 2010a). The vapour pressure is ~0.4 kPa at 40°C (CONCAWE, 1996a).
Flash points for straight-run gas oils are generally >56°C and the self ignition temperature is typically =240°C (CONCAWE, 2010a). Straight-run gas oils having flash points between =55 °C and=75 °C meet the CLP Regulation (EC No. 1272/2008) criteria as Category 3 Flammable Liquids (H226). Straight-run gas oils do not meet classification criteria for explosiveness oroxidisingproperties under the EU CLP Regulation (EC No. 1272/2008).. The kinematic viscosity of substances in this category is between 2.1 and 27 mm2/s at 40°C (CONCAWE, 2010a).Substances having a kinematic viscosity of = 20.5 mm2/s at 40°C would meet classification criteria as aspiration hazard (H304) under CLP.
Based on information available on the properties of the substances that comprise the straight-run gas oils category of chemicals, specific data are not presented for the following endpoints: partition co-efficient, water solubility, granulometry, surface tension, flammability, explosiveness, oxidising properties, stability in organic solvents, and dissociation constant. Appropriate waiving statements are provided to indicate why data for these REACH endpoints are not applicable. The physico-chemical data presented are considered representative for the substances included in the straight-run gas oils.
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).
