Additional information
One study investigating the short-term toxicity of Didodecyl fumarate (CAS 2402-58-6) to aquatic invertebrates is available. This static study was conducted according to EU method C.2 and GLP (Küch, 1995). The test concentrations were measured using DOC analysis; however, the analysis showed that the test substance is only poorly soluble in water and thus the measurement could not be used as basis for the determination of an effect concentration. Two tests were conducted. One test applied test concentrations of 16, 64 and 80 mg/L test prepared using a vehicle and the other test applied a 100 mg/L test solution prepared without using a vehicle. The observed undissolved test material was not removed from the treatments in test 1, but the test solution is filtered in test 2. 48 h-EC50 values of 96 mg/L (test 1) and > 100 mg/L (test 2) are determined for Daphnia magna on the basis of the nominal concentrations. As no toxicity was observed using the filtered test solution the observed adverse effects in test 1 is expected to be related to physical interferences rather than systemic toxicity.
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.
