Description of key information
No relevant information is available on the toxicity of dimethylsebacate to soil organisms. Therefore, we applied the EPM strategy to soil risk assessment, following the rules set out in the integrated testing strategy (ITS) detailed in section R.7.11.6., Chapter R.7c of the ECHA Guidance on information requirements and chemical safety assessment (version 2.0, Nov. 2014, pp. ). No relevant terrestrial toxicity datum is available for derivation of a PNECsoil. Therefore, a “soil hazard category” was assigned to dimethylsebacate. Dimethylsebacate is not very toxic to aquatic organisms and is readily biodegradable. In addition, both partition (inferior to 5) and adsorption (inferior to 3) coefficients allow considering dimethylsebacate as not very adsorptive. Dimethylsebacate falls therefore within the scheme of “Hazard category 1”, which states that only the EPM method is required for the screening assessment. When PEC/PNECscreen is inferior to 1, then “no toxicity testing for soil organisms need to be done”, as stated in the R.7c Guidance. The new RCR derived from the new freshwater PNEC with the EPM method is inferior to 1 for the terrestrial compartment. This information is presented in the updated CSA. Therefore, following the rules set out insection R.7.11.6., Chapter R.7c of the ECHA Guidance on information requirements and chemical safety assessment (version 2.0, November 2014), and in accordance with the REACh regulation EC 1907/2006 annexes IX and X, section 9.4, column 2, no testing on terrestrial organism is needed.
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.
