Additional information
As no acute study is available for assessing the toxicity of the substance on fish, in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 Grouping of substances, a read-across to the structurally related Alkyl Dimethyl betaine (EC-No. 931-700-2) was applied. The read across is justified due to the structural similarity of the analogue substances and similar physico-chemical properties resulting in a similar environmental fate and ecotoxicity profile. Further justification is given in the analogue justification attached to section 13 in IUCLID.
One key GLP study was conducted according to OECD guideline 203 using Brachidanio (Danio) rerio (Jung, 1989). Fish were exposed for 96 h to 4 test concentrations under static condictions. Mortality was assessed and revealed a LC 50 (96h) of 14.8 mg/L for the test substance in aqueous solution (30% in water) and a LC50 (96h) of 4.44 mg a.i./L.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.
