Description of key information
In a read-across publication an aquatic toxicity test with 9 -octadecenoic acid sodium salt exposed to fish was reported. The LC50 (96 h) was found to be greater than 100 mg/L.
Key value for chemical safety assessment

Additional information
A publication is available in which the acute toxicity of the analogue substance (9-Octadecenoic Acid, sodium salt, CAS-Nr. 143 -19 -1). was determined for freshwater. Therefore, red killifish (Oryzias latipes) were exposed to several concentrations of the read across substance after acclimatization. The test followed a semi-static procedure with an exposure time of 96 h. As a result, a LC50 value of 217 mg/L in freshwater was determined.
Additionally, an acute aquatic toxicity test was conducted on fish to assess the LC50 (96 h) of 9 -octadecenoic acid sodium salt. The study was conducted in 2000 according to OECD guideline 203 and in compliance with GLP by the MOE (Ministry of the Environment in Japan). As a result, an LC50 of >100 mg/L was revealed.
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.
