Additional information
1. Long-term toxicity to aquatic invertebrates:
In the Steber et al. study the chronic toxicity of C16-18 Tallow alcohol sulfate on Daphnia magna was determined in a test according to 'Verfahrensvorschlag Verlaengerter Toxizitaetstest bei Daphnia magna (Bestimmung der NOEC fuer Reproduktionsrate, Mortalitaet und den Zeitpunkt des ersten Auftretens von Nachkommen; 21d), Texte Umweltbundesamt Berlin, 16/84 (Heft 5). Based on evaluation of reproductive toxicity effects in a 21 d chronic toxicity study on daphnia the NOEC was determined to be 16.5 mg/l.
2. Long-term toxicity to aquatic invertebrates:
In the Verge et al. study the chronic toxicity of Sulfuric acid, mono-C16-18-alkyl esters, sodium salts on Daphnia magna was determined in a 21d chronic toxicity test according to OECD 202 requirements. Based on evaluation of toxicity effects in this 21 d chronic toxicity study on daphnia the EC50 was determined to be 4.2 mg/l. The justification to use read-across data from supporting substances is provided in Section 13 of the IUCLID dossier.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).
