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, heavy 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.
