Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 309-870-9 | CAS number: 101316-66-9 A complex combination of hydrocarbons obtained during the sorptions of toluene from a hydrocarbon fraction from cracked gasoline treated with hydrogen in the presence of a catalyst. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C6 through C8 and boiling in the range of approximately 80°C to 135°C (176°F to 275°F).

Description of key information
The relative density of streams in this category is in the range 0.6915 to 0.932 at 20ºC.
Key value for chemical safety assessment
Additional information
Proprietary studies were available from GKA Competence Centre Analytics (2008a, 2008b) for the streams 68477-39-4 (relative density 0.89 at 20ºC) and 68467-55-1 (relative density 0.69 at 20ºC). These studies were in accordance with a standard guideline and are considered reliable for assessment. For the case of the stream 68467-55-1 the substance tested contained ca. 1% benzene which results in the substance not meeting the category chemical justification criteria. However, the amount of benzene is small and will not invalidate the result of this physical chemical endpoint. The data from these studies will be read across to other members of the category.
RÜTGERS Germany GmbH, Analytisches Zentrallabor (AZL) (2010) provided data for the stream 64742-94-5 (density 0.932 ml/g at 20ºC) via a signed Certificate of Analysis. This data provided details on the method used and was considered adequate for assessment.
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.
