Description of key information
The acute toxicity of aluminum, benzoate C16-18-fatty acids complexes to Daphnia showed no effects at a water accommodated fraction nominal loading rate of 100 mg/L. Therefore, the 48 hour EL50 is determined to be > 100 mg/L (WAF).
Key value for chemical safety assessment
Additional information
The acute toxicity to Daphnia was determined in a GLP-compliant, static limit test (Harlan 2013) following OECD guideline 202. As no effects were observed in the preliminary range finding test, the definitive toxicity to Daphnia test was conducted as a limit test at a nominal loading rate of 100 mg/L alongside a blank control. Twenty Daphnia divided into four replicates were exposed to a water accommodated fraction of aluminum, benzoate C16-18-fatty acids complexes for 48 hours in standard ecotoxicity media adjusted to a hardness of approximately 150 mg/L CaCO3. Observations of immobilisation or abnormalities of behaviour or appearance of the Daphnia were made at 24 and 48 hours and the test solution analysed for aluminium content and total organic carbon at test initiation and termination. As no effects were observed, the 48 hour EL50 is determined to be > 100 mg/L (WAF).
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.
