Additional information
Discussion concerns tests of the whole substance and also an understanding of the properties of blocks and constituents. The constituent properties are needed for the risk characterisation conducted using the hydrocarbon block method and for the PBT assessment.
As part of the New Substance dossier (under Directive 67/548/EEC) it was demonstrated by prediction that short term E(L)C50values would not be achieved at up to 1000 mg/l loading as WAF. This is consistent with the measured data. Prediction for long-term effects data is difficult since it depends markedly on the model used. The available measured long-term data are not inconsistent with the properties of the constituents. PNECs are therefore based on HC5 values calculated using PETROTOX for the hydrocarbon blocks identified (see CSR, table 1.3.5).Conclusion on classification
GTL Kerosine ("Hydrocarbons, C8-C16, branched and linear") is not classified in the EU for acute or chronic toxicity on the grounds that modelled ecotoxicity properties indicate that the substance would not be toxic at a loading rate of 100 mg/l. This proposal is supported by measured data for representative samples of the substance for which there were no toxic effects at a loading rate of 100 mg/l or higher with fish,Daphnia and algae. Furthermore, long-term ecotoxicity studies with fish and Daphnia using the related substance GTL Gasoil ("Hydrocarbons, C8-C26, branched and linear") gave NOELR values of 100 and 32 mg/l respectively.
Although constituents are present which have high log Kow, their degradability (see also CSR, sections 4.1 and 8) and lack of long-term toxicity at loading rates above 1 mg/l indicate that classification as Chronic Category 4 is not required according to the criteria of Regulation 1272/2008/EC.
In conclusion, GTL Kerosine is not classified for the environment.
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).
