Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 269-646-0 | CAS number: 68308-34-9 The complex combination of hydrocarbons obtained by the thermal decomposition (at 399°C (750°F) or higher) of kerogen. It consists of hydrocarbons and heterocyclic compounds containing nitrogen, sulfur or oxygen.
Biodegradation in water and sediment: simulation tests

- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex IX, Simulation testing on Ultimate Degradation in Surface Water (required in section 9.2.1.2) does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labeling purposes and PBT assessment, so no further testing is required. - Transformation products:
- no
- Endpoint:
- biodegradation in water: sediment simulation testing
- Data waiving:

In accordance with column 2 of REACH Annex IX, Sediment Simulation testing (required in section 9.2.1.4) does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labeling purposes and PBT assessment, so no further testing is required. Also direct and indirect exposure of the sediment is unlikely. - Transformation products:
- no
- Endpoint:
- biodegradation in water and sediment: simulation testing, other
- Remarks:
- identification of degradation products
- Data waiving:
- study technically not feasible

- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Section 2 of Annex XI of the REACH regulation, the identification of degradation products study (required in section 9.2.3), does not need to be conducted if it is not technically possible to do so. Shale oils are complex mixtures of various different compounds of low solubility, not chemically well defined with no main component. Therefore, the identification of degradation products study cannot be determined for shale oil, light fraction. - Endpoint:
- biodegradation in water and sediment: simulation testing, other
- Remarks:
- Further biotic degradation testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:

- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex X, Further biotic degradation testing (required in section 9.2.1) does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment, so no further testing is required.

Description of key information
In accordance with column 2 of REACH Annex IX, degradation testing in Surface Water (required in section 9.2.1.2), and Sediment (required in section 9.2.1.4), does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment, so no further testing is required.
In accordance with Section 2 of Annex XI of the REACH regulation, the identification of degradation products study does not need to be conducted if it is not technically possible to do so. Shale oils are complex mixtures of various different compounds of low solubility, not chemically well defined with no main component. Therefore, the identification of degradation products study cannot be determined for shale oil, middle fraction.
In accordance with column 2 of REACH Annex X, Further biotic degradation testing (required in section 9.2.1) does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment, so no further testing is required.

Additional information
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.
