Additional information
The acute toxicity of "DIBUTYLFUMARATE" to Daphnia magna was determined in a 48 hours static test. The following guideline was applied: Annex 5 (92/69/EEC) to Commission Directive 92/32/EEC, C.2. Acute Toxicity for Daphnia,29 December 1992.
Neonates of Daphnia magna, not more than 24 hours old, were exposed to five concentrations of the test substance (nominal: 0.010, 0.018, 0.032, 0.056 and 0.100 mg mg test substance / L) in reconstituted water according ISO 6341.
The 48-hour EC50 in Daphnia magna was 0.1 mg / L in a aqueous solution of Dibutylfumerate, based on immobilisation of the test animals. The EC0 is estimated to be 0.06 mg/L. The results are based on the nominal concentrations.
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).
