Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 265-103-7 | CAS number: 64742-04-7 A complex combination of hydrocarbons obtained as the extract from a solvent extraction process. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C20 through C50. This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.

Description of key information
Additional information
Key study data are available for each relevant physicochemical endpoint for distillate aromatic extracts. All substances in the category are highly viscous fluids 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 -6 to 50°C (CONCAWE, 2010a). Boiling points for members of this category range from 200 to 640°C (CONCAWE, 2010a). The absolute density range for the category is from 930 to 1070 Kg/m3 at 15°C.(CONCAWE, 2010a) while the vapour pressure is less than 0.01 kPa at 20°C (CONCAWE, 1992a).
Flash points for members of this category are >140°C (CONCAWE, 1992a and 2010a). Self-ignition temperatures for distillate aromatic extracts are in the range of 250°C to 410°C at 1013 hPa (CONCAWE, 1992a). Distillate aromatic extracts are not considered to be flammable or explosive and do not meet the EU CLP Regulation (EC No. 1272/2008) classification criteria for oxidising properties. The viscosity of substances in this category is >10 mm2/sec at 40°C and ranges from 3.8 to 124 mm2/s at 100°C (CONCAWE, 2010a). Substances in this category having a viscosity ≤20.5 mm2/s at 40°C meet the criteria for classification as an aspiration hazard according to the EU CLP Regulation (EC No. 1272/2008).
Based on information available on the properties of the substances that comprise the distillate aromatic extracts category of chemicals, specific data are not presented for the following endpoints: appearance/physical state/colour, partition coefficient, water solubility, granulometry, surface tension, stability in organic solvents, flammability, explosiveness, oxidising properties, 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 category distillate aromatic extracts.
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.
