Additional information
The acute toxicity of the tested substance to aquatic invertebrates was determined in accordance with the draft ISO Testing Method 14669:1999 (E). Nominal test concentrations of the test material were prepared over the range 1 to 1000 mg/l. The marine invertebrateAcartia tonsawas exposed to the test concentrations in order to determine the concentration which killed 50% of the copepods over 48 hours (LC50). The lowest concentration of test material producing 100% mortality could not be determined from this study. All concentrations of test material produced some mortality in this study. All parameters measured in this study lay within 95% confidence limits. The test material is not considered toxic toAcartia tonsawithin the conditions of this study. The registered substance is not considered to be toxic to aquatic invertebrates based on the findings of this study. In addition, an equivalent study was conducted on a monoethanolamine, a component which makes 50% of the registered reaction mass. The 48 hour LC50 of monoethanolamine was found to be 660 mg/L. Monoethanolamine is not considered to be toxic to aquatic invertebrates.
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).
